一 : SpringMVC

  • 接收参数
基本数据类型+String
JavaBean
一对一
一对多
Map
List
  • 注解
@RequestMapping("/user/add")  请求路径与方法绑定
@RequestParam()  提交参数与后台接收参数不一致问题
@PathVariable()     获取请求路径中的一部分,作为一个参数

Model:将数据存入到Request中

  • SpringMVC数据响应、文件上传、异常处理、拦截器
  • SpringMVC数据响应
void
String
ModelAndView
  • 文件上传-SpringMVC
MultipartFile : 文件封装
MultipartFile.transferTo(new File())
  • 拦截器
preHandler:方法执行前执行
postHandler:方法执行后执行
afterCompletion:方法执行页面渲染后执行

二 : SSM集成

整合的思路

  1. 先搭建整合的环境
  2. 再搭建SpringMVC,只搭建控制层
  3. 再搭建Service层,集成Spring
  4. 最后使用Spring整合MyBatis框架

三大框架集成:

  1. 工程搭建环境

  创建工程名,引入依赖

  • 创建相对应的javabean

  2.集成SpringMVC框架

  • 集成SpringMVC的步骤

  

1.web.xml中配置SpringMVC核心控制器
2.web.xml中配置SpringMVC的POST编码过滤器
3.创建SpringMVC的核心配置文件springmvc.xml
4.在SpringMVC的核心配置文件中配置注解驱动、包扫描、视图解析器、静态资源过滤等
  • 创建控制层

  例如:

@Controller
@RequestMapping(value = "/account")
public class AccountController {

    /**
     * list集合查询
     * @return
     */
    @RequestMapping(value = "/list")
    public String list(){
        System.out.println("AccountController.list");
        return "list";
    }

    /***
     * 增加
     * @return
     */
    @RequestMapping(value = "/add")
    public String add(){
        System.out.println("AccountController.add");
        return "redirect:/account/list";
    }
}
  •   配置web.xml

    <mvc:resources location="/js/" mapping="/js/**" />

    <!-- 开启对SpringMVC注解的支持 -->
    <mvc:annotation-driven />
</beans>

  3.集成Spring框架

  • (1)创建Service接口

  

public interface AccountService {

    /***
     * 集合
     */
    List<Account> list();

    /***
     * 增加
     */
    int add(Account account);
}
  • (2)创建Service实现类

  

@Service
public class AccountServiceImpl implements AccountService {

    /**
     * 集合
     * @return
     */
    @Override
    public List<Account> list() {
        System.out.println("AccountServiceImpl.list");
        return null;
    }

    /**
     * 增加
     * @param account
     * @return
     */
    @Override
    public int add(Account account) {
        System.out.println("AccountServiceImpl.add");
        return 0;
    }
}
  • 创建spring核心配置文件

  

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">

 需改springmvc.xml包扫描

<!-- 扫描controller的注解,别的不扫描 -->
<context:component-scan base-package="com.bky" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

修改spring.xml包扫描

<!--开启注解扫描,要扫描的是service和dao层的注解,要忽略web层注解,因为web层让SpringMVC框架去管理-->
<context:component-scan base-package="com.bky">
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!-- 配置Spring的监听器 -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置加载类路径的配置文件 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
</context-param>

  4.集成mybatis框架

  • dao层代码
public interface AccountDao {

    /***
     * 保存账号
     * @param account
     */
    @Insert("insert into account(name,money)values(#{name},#{money})")
    int add(Account account);

    /***
     * 查询所有
     * @return
     */
    @Select("select * from account")
    List<Account> list();
}
  • 配置xml
在Spring。xml中添加以下配置

<!-- 配置的连接池对象 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://127.0.0.1:3306/spring5"/>
    <property name="username" value="root"/>
    <property name="password" value="itcast"/>
</bean>

<!-- 配置SqlSession的工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
</bean>

<!-- 配置扫描dao的包 -->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.bky.dao"/>
</bean>

  

  5.声明式事务配置

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

<!-- 配置事务通知 -->
<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
        <tx:method name="list*" read-only="true"/>
        <tx:method name="*" isolation="DEFAULT"/>
    </tx:attributes>
</tx:advice>

<!-- 配置AOP增强事务 -->
<aop:config>
    <aop:advisor advice-ref="txAdvice" pointcut="execution(public * com.bky.service.impl.*.*(..))"/>
</aop:config>

  6.项目完整配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  • 之前的是使用Springmvc容器和Spring容器,下面是使用一个容器Springmvc,将所有的配置文件放入其中。
  • 这样做得好处是,不会产生包冲突,增加配置文件的查找效率
