SpringMVC Spring Mybatis整合篇

1、创建WEB项目

创建项目：（ssmbuild）步骤略........

给项目添加lib文件夹，用于存放jar包：

在WEB-INF目录下创建lib文件夹：

创建完成：运行项目时需要把jar导入到lib目录下

2、pom文件

<?xml version="1.0" encoding="UTF-8"?>

            <version>2.10.2</version>
        </dependency>
    </dependencies>

    <!--2.解决资源过滤问题-->
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>

                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

</project>

3、配置web.xml

<!--注册乱码filter-->
<filter>
    <filter-name>encoding</filter-name>
    <filter-class>com.applesnt.filter.GenericEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>utf-8</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>encoding</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<!--注册DispatcherServlet-->
<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--关联一个spring配置文件:重点-->
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </init-param>
    <!--启动级别-1-->
    <load-on-startup>1</load-on-startup>
</servlet>

<!--/ 匹配所有的请求；（不包括.jsp）-->
<!--/* 匹配所有的请求；（包括.jsp）-->
<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<!--session过期时间-->
<session-config>
    <session-timeout>30</session-timeout>
</session-config>

4、创建spring配置文件：applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

5、创建解决乱码的fileter

com\applesnt\filter\GenericEncodingFilter.java

package com.applesnt.filter;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.Map;

public class GenericEncodingFilter implements Filter {
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        //处理response的字符编码
        HttpServletResponse myResponse=(HttpServletResponse) response;
        myResponse.setContentType("text/html;charset=UTF-8");

        // 转型为与协议相关对象
        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        // 对request包装增强
        HttpServletRequest myrequest = new MyRequest(httpServletRequest);
        chain.doFilter(myrequest, response);

    }

    public void destroy() {

    }

    //自定义request对象，HttpServletRequest的包装类
    class MyRequest extends HttpServletRequestWrapper {

        private HttpServletRequest request;
        //是否编码的标记
        private boolean hasEncode;

        //定义一个可以传入HttpServletRequest对象的构造函数，以便对其进行装饰
        public MyRequest(HttpServletRequest request) {
            super(request);// super必须写
            this.request = request;
        }

        // 对需要增强方法 进行覆盖
        @Override
        public Map getParameterMap() {
            // 先获得请求方式
            String method = request.getMethod();
            if (method.equalsIgnoreCase("post")) {
                // post请求
                try {
                    // 处理post乱码
                    request.setCharacterEncoding("utf-8");
                    return request.getParameterMap();
                } catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                }
            } else if (method.equalsIgnoreCase("get")) {
                // get请求
                Map<String, String[]> parameterMap = request.getParameterMap();
                if (!hasEncode) { // 确保get手动编码逻辑只运行一次
                    for (String parameterName : parameterMap.keySet()) {
                        String[] values = parameterMap.get(parameterName);
                        if (values != null) {
                            for (int i = 0; i < values.length; i++) {
                                try {
                                    // 处理get乱码
                                    values[i] = new String(values[i]
                                            .getBytes("ISO-8859-1"), "utf-8");
                                } catch (UnsupportedEncodingException e) {
                                    e.printStackTrace();
                                }
                            }
                        }
                    }
                    hasEncode = true;
                }
                return parameterMap;
            }
            return super.getParameterMap();
        }

        //取一个值
        @Override
        public String getParameter(String name) {
            Map<String, String[]> parameterMap = getParameterMap();
            String[] values = parameterMap.get(name);
            if (values == null) {
                return null;
            }
            return values[0]; // 取回参数的第一个值
        }

        //取所有值
        @Override
        public String[] getParameterValues(String name) {
            Map<String, String[]> parameterMap = getParameterMap();
            String[] values = parameterMap.get(name);
            return values;
        }
    }
}

6、创建数据库表以及vo对象

CREATE TABLE `books` (
  `bookID` int(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
  `bookName` varchar(100) NOT NULL COMMENT '书名',
  `bookCounts` int(11) NOT NULL COMMENT '数量',
  `detail` varchar(200) NOT NULL COMMENT '描述',
  KEY `bookID` (`bookID`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

INSERT INTO `books` VALUES ('1', 'Java', '1', '从入门到放弃');
INSERT INTO `books` VALUES ('2', 'MySQL', '10', '从删库到跑路');
INSERT INTO `books` VALUES ('3', 'Linux', '5', '从进门到进牢');

com\applesnt\vo\Books.java

package com.applesnt.vo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

7、创建Mapper接口

com\applesnt\mapper\BooksMapper.java

package com.applesnt.mapper;

import com.applesnt.vo.Books;

import java.util.List;

public interface BooksMapper {

    /*新增一本书*/
    public int addBook(Books books);

    /*删除一本书*/
    public int deleteBook(int id);

    /*修改一本书*/
    public int updateBook(Books books);

    /*查询一本书*/
    public Books queryBookById(int id);

    /*查询所有书*/
    public List<Books> queryBook();
}

8、创建mapper对应的xml

com\applesnt\mapper\BooksMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.applesnt.mapper.BooksMapper">

    <insert id="addBook" parameterType="Books">
        insert into books(bookName,bookCounts,detail)
        values (#{bookName}, #{bookCounts}, #{detail})
    </insert>

    <delete id="deleteBook" parameterType="int">
        delete from books where bookID = #{id}
    </delete>

    <update id="updateBook" parameterType="Books">
        update books set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID = #{bookID}
    </update>

    <!--resultType：别名-->
    <select id="queryBookById" resultType="books">
        select * from books where bookID = #{id}
    </select>

    <select id="queryBook" resultType="books">
        select * from books
    </select>

</mapper>

9、创建jdbc.properties数据库连接文件

resources\jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://ip:3306/my_test?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=xxxxxxxx

10、创建Mybatis主配置文件

resources\mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <settings>
        <!--打印sql语句-->
        <setting name="logImpl" value="STDOUT_LOGGING" />
        <!-- 全局性设置懒加载 -->
        <setting name="lazyLoadingEnabled" value="true"/>
        <!-- 每个属性都按需加载 -->
        <setting name="aggressiveLazyLoading" value="false"/>
        <!-- 开启驼峰命名 -->
        <setting name="mapUnderscoreToCamelCase" value="true" />
    </settings>

    <!--开启别名-->
    <typeAliases>
        <package name="com.applesnt.vo" />
    </typeAliases>

    <!--mapper文件-->
    <mappers>
        <mapper resource="com/applesnt/mapper/BooksMapper.xml" />
    </mappers>

</configuration>

11、构建DAO层的spring配置文件

resources\spring-mapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd">

    <!--加载jdbc配置文件-->
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:jdbc.properties</value>
            </list>
        </property>
    </bean>

    <!--数据源配置 数据源提供者包括：spring、c3p0、dbcp、druid-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${jdbc.driver}"></property>
        <property name="url" value="${jdbc.url}"></property>
        <property name="username" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--配置得到SqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <!--绑定mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    </bean>

    <!--通过MapperScannerConfigurer配置dao接口扫描包 实现动态注入到spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
        <!--要扫描的dao包-->
        <property name="basePackage" value="com.applesnt.mapper" />
    </bean>

</beans>

12、创建Service接口

com\applesnt\service\BooksService.java

package com.applesnt.service;

import com.applesnt.vo.Books;
import java.util.List;

public interface BooksService {

    /*新增一本书*/
    public int addBook(Books books);

    /*删除一本书*/
    public int deleteBook(int id);

    /*修改一本书*/
    public int updateBook(Books books);

    /*查询一本书*/
    public Books queryBookById(int id);

    /*查询所有书*/
    public List<Books> queryBook();
}

13、创建Service接口实现类

com\applesnt\service\impl\BooksServiceImpl.java

package com.applesnt.service.impl;

import com.applesnt.mapper.BooksMapper;
import com.applesnt.service.BooksService;
import com.applesnt.vo.Books;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class BooksServiceImpl implements BooksService {

    @Autowired
    /*通过class自动注入*/
    private BooksMapper booksMapper;

    public void setBooksMapper(BooksMapper booksMapper) {
        this.booksMapper = booksMapper;
    }

    public int addBook(Books books) {
        return booksMapper.addBook(books);
    }

    public int deleteBook(int id) {
        return booksMapper.deleteBook(id);
    }

    public int updateBook(Books books) {
        return booksMapper.updateBook(books);
    }

    public Books queryBookById(int id) {
        return booksMapper.queryBookById(id);
    }

    public List<Books> queryBook() {
        return booksMapper.queryBook();
    }
}

14、构建Service层的spring配置文件

resources\spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--注解版扫描包，这个包下面的注解就会生效-->
    <context:component-scan base-package="com.applesnt.service" />

    <!--<bean class="com.applesnt.service.impl.BooksServiceImpl">
        <property name="booksMapper" ref="booksMapper"></property>
    </bean>-->

    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <!--给哪些方法配置事务-->
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>

    <!--配置事务切入-->
    <aop:config>
        <aop:pointcut id="txpoint" expression="execution(* com.applesnt.mapper.*.*(..))"></aop:pointcut>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txpoint"></aop:advisor>
    </aop:config>

</beans>

15、创建controller

com\applesnt\controller\BooksController.java

package com.applesnt.controller;

import com.applesnt.service.BooksService;
import com.applesnt.vo.Books;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.List;

@Controller
public class BooksController {

    @Autowired
    /*通过class自动注入*/
    private BooksService booksService;

    /*查询书籍列表*/
    @RequestMapping("/getbooks")
    public String queryBook(Model model){
        List<Books> booksList = this.booksService.queryBook();
        model.addAttribute("booklist",booksList);
        return "books";
    }

    /*跳转至添加书籍页面*/
    @RequestMapping("/toAddBook")
    public String toAddBook(){
        return "addbook";
    }

    /*添加书籍*/
    @RequestMapping("/addBook")
    public String addBook(Books books){
        booksService.addBook(books);
        return "redirect:/getbooks";/*重定向到列表页*/
    }

    /*跳转至修改书籍页面*/
    @RequestMapping("/toUpdateBook/{id}")
    public String toUpdateBook(@PathVariable int id,Model model){
        Books book = booksService.queryBookById(id);
        model.addAttribute("book",book);
        return "updatebook";
    }

    /*修改书籍*/
    @RequestMapping("/updateBook")
    public String toUpdateBook(Books book){
        booksService.updateBook(book);
        return "redirect:/getbooks";/*重定向到列表页*/
    }

    /*删除书籍*/
    @RequestMapping("/deleteBook/{id}")
    public String deleteBook(@PathVariable int id,Model model){
        booksService.deleteBook(id);
        return "redirect:/getbooks";/*重定向到列表页*/
    }

}

16、构建Controller层的spring配置文件

resources\springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <context:component-scan base-package="com.applesnt.controller"/>

    <!-- 让Spring MVC不处理静态资源 -->
    <mvc:default-servlet-handler />

    <!--annotation-driven配置帮助我们完成处理器映射器和处理器适配器-->
    <mvc:annotation-driven />

    <!--视图解析器:DispatcherServlet给他的ModelAndView-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/WEB-INF/jsp/"/>

        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

17、把SpringMVC Spring Mybatis配置文件合并

resources\applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="spring-mapper.xml"/>
    <import resource="spring-service.xml"/>
    <import resource="springmvc-servlet.xml"/>

</beans>

18、访问测试：

http://localhost/index.jsp

项目涉及到的页面：如下

web\index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
  </head>
  <body>
  <h3>
    <a href="${pageContext.request.contextPath}/getbooks">书籍管理</a>
  </h3>
  </body>
</html>

            <table class="table table-bordered table-hover">
                <thead>
                <tr>
                    <th>书籍编号</th>
                    <th>书籍名称</th>
                    <th>书籍库存</th>
                    <th>书籍描述</th>
                    <th>操作</th>
                </tr>
                </thead>
                <tbody>
                <c:forEach var="book" items="${booklist}">
                    <tr>
                        <td>${book.bookID}</td>
                        <td>${book.bookName}</td>

                        <td>${book.detail}</td>
                        <td><a href="${pageContext.request.contextPath}/toUpdateBook/${book.bookID}" >修改</a>

                    </tr>
                </c:forEach>
                </tbody>
            </table>
