SSM框架搭建(Spring+SpringMVC+MyBatis)与easyui集成并实现增删改查实现
一、用myEclipse初始化Web项目
新建一个web project:
二、创建包
controller //控制类
service //服务接口
service.impl
//服务实现类
dao //data access object(接口)
dao.impl //实现类
domain //实体类
mappers //mybatis的配置映射文件
util //工具类
三、是maven方式引入类库
3.1启动tomcat服务
3.2给web项目添加maven支持(引入maven私服库)
将web项目转化为maven项目:
3.3引入依赖
spring
mybatis
spring mvc
c3p0类库
MySQL
.......
3.4主要是编写pom.xml文件
- <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

四、创建dao和service的基础类库
UserDao.Java如下:
- package com.liuhai.eshop.dao;
- import java.util.List;
- import java.util.Map;
- import com.liuhai.eshop.domain.User;
- /**
- * 用户DAO接口
- * @author Administrator
- *
- */
- public interface UserDao {
- /**
- * 用户登录
- * @param user
- * @return
- */
- public User login(User user);
- /**
- * 查询所有用户
- * @return
- */
- public List<User> getAll();
- /**
- * 根据条件查询用户
- * @param user
- * @return
- */
- public User getUser(User user);
- /**
- * 删除用户
- * @param user
- * @return
- */
- public int delete(int id);
- /**
- * 更新用户
- * @param user
- * @return
- */
- public int update(User user);
- /**
- * 添加用户
- * @param user
- * @return
- */
- public int add(User user);
- /**
- * 用户查询
- * @param map
- * @return
- */
- public List<User> find(Map<String,Object> map);
- /**
- * 获取总记录数
- * @param map
- * @return
- */
- public Long getTotal(Map<String,Object> map);
- /**
- * 根据id查询用户
- * @param id
- * @return
- */
- public User getUserById(int id);
- }
UserService.java 用户service层接口如下:
- package com.liuhai.eshop.service;
- import java.util.List;
- import java.util.Map;
- import com.liuhai.eshop.domain.User;
- public interface UserService {
- public List<User> getAll();
- public User getUser(User user);
- public int delete(int id);
- public int update(User user);
- public int add(User user);
- public List<User> find(Map<String,Object> map);
- public Long getTotal(Map<String,Object> map);
- public User getUserById(int id);
- }
UserServiceImpl.java 用户service实现层如下:
- package com.liuhai.eshop.service.impl;
- import java.util.List;
- import java.util.Map;
- import javax.annotation.Resource;
- import org.springframework.stereotype.Service;
- import com.liuhai.eshop.dao.UserDao;
- import com.liuhai.eshop.domain.User;
- import com.liuhai.eshop.service.UserService;
- @Service(value="userService")
- public class UserServiceImpl implements UserService {
- private UserDao userDao;
- @Resource
- public void setUserDao(UserDao userDao) {
- this.userDao = userDao;
- }
- @Override
- public List<User> getAll() {
- return userDao.getAll();
- }
- @Override
- public User getUser(User user) {
- return userDao.getUser(user);
- }
- @Override
- public int delete(int id) {
- return userDao.delete(id);
- }
- @Override
- public int update(User user) {
- return userDao.update(user);
- }
- @Override
- public int add(User user) {
- return userDao.add(user);
- }
- @Override
- public List<User> find(Map<String, Object> map) {
- return userDao.find(map);
- }
- @Override
- public Long getTotal(Map<String, Object> map) {
- return userDao.getTotal(map);
- }
- public User getUserById(int id){
- return userDao.getUserById(id);
- }
- }
user实体类如下:
- package com.liuhai.eshop.domain;
- import java.io.Serializable;
- /**
- * 用户实体
- * @author Administrator
- *
- */
- public class User implements Serializable{
- private static final long serialVersionUID = 1L;
- private Integer id;
- private String userName;
- private String password;
- private Integer age;
- private String trueName;
- private String email;
- private String phone;
- private String roleName;
- public Integer getId() {
- return id;
- }
- public void setId(Integer id) {
- this.id = id;
- }
- public Integer getAge() {
- return age;
- }
- public void setAge(Integer age) {
- this.age = age;
- }
- public String getPassword() {
- return password;
- }
- public void setPassword(String password) {
- this.password = password;
- }
- public String getUserName() {
- return userName;
- }
- public void setUserName(String userName) {
- this.userName = userName;
- }
- public String getTrueName() {
- return trueName;
- }
- public void setTrueName(String trueName) {
- this.trueName = trueName;
- }
- public String getEmail() {
- return email;
- }
- public void setEmail(String email) {
- this.email = email;
- }
- public String getPhone() {
- return phone;
- }
- public void setPhone(String phone) {
- this.phone = phone;
- }
- public String getRoleName() {
- return roleName;
- }
- <h1><a name="t8"></a> public void setRoleName(String roleName) {</h1> this.roleName = roleName;
- }
- }
五、配置spring配置文件、jdbc和日志属性文件、myBatis的mapper.xml文件
5.1 spring配置文件applicationContext.xml如下:
- <?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:aop="http://www.springframework.org/schema/aop"
- xmlns:context="http://www.springframework.org/schema/context"
- 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/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
- http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
- http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
- <!-- 属性配置文件 -->
- <context:property-placeholder location="classpath:jdbc.properties"/>
- <!-- 组件扫描,指定spring管理哪些bean -->
- <context:component-scan base-package="com.liuhai.eshop.dao.impl,com.liuhai.eshop.service.impl"></context:component-scan>
- <!-- 注解驱动 -->
- <tx:annotation-driven/>
- <!-- 创建数据源 -->
- <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
- <property name="driverClass" value="${jdbc.driverclass}"></property>
- <property name="jdbcUrl" value="${jdbc.url}"></property>
- <property name="user" value="${jdbc.username}"></property>
- <property name="password" value="${jdbc.password}"></property>
- <property name="initialPoolSize" value="${c3p0.pool.size.init}"></property>
- <property name="minPoolSize" value="${c3p0.pool.size.min}"></property>
- <property name="maxPoolSize" value="${c3p0.pool.size.max}"></property>
- <property name="acquireIncrement" value="${c3p0.pool.size.increment}"></property>
- </bean>
- <!-- spring和MyBatis完美整合,不需要mybatis的配置映射文件 -->
- <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
- <property name="dataSource" ref="dataSource" />
- <!-- 自动扫描mapping.xml文件 -->
- <property name="mapperLocations" value="classpath:com/liuhai/eshop/mappers/*.xml"></property>
- </bean>
- <!-- DAO接口所在包名,Spring会自动查找其下的类 -->
- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
- <property name="basePackage" value="com.liuhai.eshop.dao"></property>
- <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
- </bean>
- <!-- 事务管理器,service层面上实现事务管理的 -->
- <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
- <property name="dataSource" ref="dataSource"></property>
- </bean>
- </beans>
5.2 jdbc属性文件jdbc.properties如下:
- jdbc.driverclass=com.mysql.jdbc.Driver
- jdbc.url=jdbc\:mysql\://localhost\:3306/eshop
- jdbc.username=root
- jdbc.password=123456
- c3p0.pool.size.max=10
- c3p0.pool.size.min=2
- c3p0.pool.size.init=3
- c3p0.pool.size.increment=2
- hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
- hibernate.show_sql=true
- hibernate.hbm2ddl.auto=none
5.3 日志属性文件log4j.properties如下:
- log4j.rootLogger=INFO,Console,File
- #定义日志输出目的地为控制台
- log4j.appender.Console=org.apache.log4j.ConsoleAppender
- log4j.appender.Console.Target=System.out
- #可以灵活地指定日志输出格式,下面一行是指定具体的格式
- log4j.appender.Console.layout = org.apache.log4j.PatternLayout
- log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
- log4j.logger.java.sql.ResultSet=INFO
- log4j.logger.org.apache=INFO
- log4j.logger.java.sql.Connection=DEBUG
- log4j.logger.java.sql.Statement=DEBUG
- log4j.logger.java.sql.PreparedStatement=DEBUG
- #文件大小到达指定尺寸的时候产生一个新的文件
- log4j.appender.File = org.apache.log4j.RollingFileAppender
- #指定输出目录
- log4j.appender.File.File = logs/ssm.log
- #定义文件最大大小
- log4j.appender.File.MaxFileSize = 10MB
- # 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志
- log4j.appender.File.Threshold =INFO
- log4j.appender.File.layout = org.apache.log4j.PatternLayout
- log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
5.4 myBatis的mapper.xml文件(UserMapper.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.liuhai.eshop.dao.UserDao">
- <!-- 定义缓存 一般是一级缓存,如果用同一个sqlsession 那么相同查询直接会从缓存中查找 -->
- <cache size="1024" flushInterval="60000" eviction="LRU" readOnly="false"></cache>
- <!-- 增加 -->
- <insert id="add" parameterType="com.liuhai.eshop.domain.User">
- insert into users values(null,#{userName},#{password},#{age},#{trueName},#{email},#{phone},#{roleName})
- </insert>
- <resultMap id="userResultMap" type="com.liuhai.eshop.domain.User" >
- <id property="id" column="id"/>
- <result property="userName" column="userName"/>
- <result property="password" column="password"/>
- <result property="age" column="age"/>
- <result property="trueName" column="trueName" />
- <result property="email" column="email" />
- <result property="phone" column="phone" />
- <result property="roleName" column="roleName" />
- </resultMap>
- <select id="getUserById" parameterType="Integer" resultMap="userResultMap">
- select * from users where id=#{id}
- </select>
- <select id="find" parameterType="com.liuhai.eshop.domain.User" resultMap="userResultMap">
- select * from users
- <where>
- <if test="userName!=null and userName!='' ">
- and userName like #{userName}
- </if>
- </where>
- <if test="start!=null and size!=null">
- limit #{start},#{size}
- </if>
- </select>
- <select id="getTotal" parameterType="Map" resultType="Long">
- select count(*) from users
- <where>
- <if test="userName!=null and userName!='' ">
- and userName like #{userName}
- </if>
- </where>
- </select>
- <!-- 用户删除 -->
- <delete id="delete" parameterType="Integer">
- delete from users where id = #{id}
- </delete>
- <!-- 用户修改 -->
- <update id="update" parameterType="com.liuhai.eshop.domain.User">
- update users
- <set>
- <if test="age != null and age != ''">age = #{age},</if>
- <if test="userName != null and userName != ''">userName = #{userName},</if>
- <if test="password != null and password != ''">password = #{password},</if>
- <if test="trueName != null and trueName != ''">trueName = #{trueName},</if>
- <if test="email != null and email != ''">email = #{email},</if>
- <if test="phone != null and phone != ''">phone = #{phone},</if>
- <if test="roleName != null and roleName != ''">roleName = #{roleName},</if>
- </set>
- where id = #{id}
- </update>
- </mapper>
六、创建测试类,测试数据源是否通了
以上spring框架及spring+mybatis配置基本完成,再就是创建测试类测试数据源是否通
首先创建一个mysql库的,再建立users表,创建测试类TestSpring.java如下:
- package com.liuhai.eshop;
- import org.junit.Test;
- import org.springframework.context.ApplicationContext;
- import org.springframework.context.support.ClassPathXmlApplicationContext;
- import com.liuhai.eshop.domain.User;
- import com.liuhai.eshop.service.UserService;
- public class TestSpring {
- @Test
- public void TestUserService() throws Exception{
- @SuppressWarnings("resource")
- ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
- UserService us=(UserService) ac.getBean("userService");
- User user=new User();
- user.setAge(1);
- user.setUserName("zhangsan");
- user.setPassword("123456");
- user.setTrueName("张三");
- us.add(user);
- }
- }
最后查询users表中是否有新插入的数据。
七、整合SpringMVC
7.1、配置spring-mvc.xml
配置里面的注释也很详细,在此就不说了,主要是自动扫描控制器,视图模式,注解的启动这三个
- <span style="font-size:18px;"><?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
- 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-4.0.xsd">
- <!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->
- <context:component-scan base-package="com.liuhai.eshop.controller"></context:component-scan>
- <!--避免IE执行AJAX时,返回JSON出现下载文件 -->
- <bean id="mappingJacksonHttpMessageConverter"
- class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
- <property name="supportedMediaTypes">
- <list>
- <value>text/html;charset=UTF-8</value>
- </list>
- </property>
- </bean>
- <!-- 启动SpringMVC的注解功能,完成请求和注解POJO的映射 -->
- <!-- 详细介绍:http://www.ibm.com/developerworks/cn/web/wa-restful/ -->
- <bean
- class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
- <property name="messageConverters">
- <list>
- <ref bean="mappingJacksonHttpMessageConverter" /> <!-- 对象转化为JSON转换器 -->
- </list>
- </property>
- </bean>
- <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
- <property name="prefix" value="/jsps/"></property>
- <property name="suffix" value=".jsp"></property>
- </bean>
- <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
- <!-- 默认编码 -->
- <property name="defaultEncoding" value="utf-8"></property>
- <!-- 文件大小最大值 -->
- <property name="maxUploadSize" value="10485760000"></property>
- <!-- 内存中的最大值 -->
- <property name="maxInMemorySize" value="40960"></property>
- </bean>
- </beans></span>
7.2、配置web.xml文件
这里面对applicationContext.xml的引入以及配置的spring-mvc的Servlet就是为了完成SSM整合,之前2框架整合不需要在此处进行任何配置。配置一样有详细注释,不多解释了。
- <?xml version="1.0" encoding="UTF-8"?>
- <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xmlns="http://java.sun.com/xml/ns/javaee"
- xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
- version="3.0">
- <display-name>web 测试页面</display-name>
- <!-- Spring和mybatis的配置文件 -->
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>classpath:applicationContext.xml</param-value>
- </context-param>
- <!-- 编码过滤器 -->
- <filter>
- <filter-name>encodingFilter</filter-name>
- <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
- <async-supported>true</async-supported>
- <init-param>
- <param-name>encoding</param-name>
- <param-value>UTF-8</param-value>
- </init-param>
- </filter>
- <filter-mapping>
- <filter-name>encodingFilter</filter-name>
- <url-pattern>/*</url-pattern>
- </filter-mapping>
- <!-- Spring监听器:启动Web容器时,自动装配ApplicationContext的配置信息,即上面的:contextConfigLocation-->
- <listener>
- <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
- </listener>
- <!-- 防止Spring内存溢出监听器 -->
- <listener>
- <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
- </listener>
- <!-- Spring MVC servlet -->
- <servlet>
- <servlet-name>springMVC</servlet-name>
- <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
- <init-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>classpath:spring-mvc.xml</param-value>
- </init-param>
- <load-on-startup>1</load-on-startup>
- <async-supported>true</async-supported>
- </servlet>
- <servlet-mapping>
- <servlet-name>springMVC</servlet-name>
- <!-- 此处可以可以配置成*.do,对应struts的后缀习惯 也可以是/-->
- <url-pattern>*.do</url-pattern>
- </servlet-mapping>
- <!-- 解决由于采用spring的过滤器,导致页面引用的JS、images、CSS发生找不到的错误;也可以用使用spring mvc 的 <mvc:resources /> 注解 用来处理静态文件 -->
- <servlet-mapping>
- <servlet-name>default</servlet-name>
- <url-pattern>*.css</url-pattern>
- </servlet-mapping>
- <servlet-mapping>
- <servlet-name>default</servlet-name>

- </servlet-mapping>
- <servlet-mapping>
- <servlet-name>default</servlet-name>
- <url-pattern>*.png</url-pattern>
- </servlet-mapping>
- <servlet-mapping>
- <servlet-name>default</servlet-name>
- <url-pattern>*.jpg</url-pattern>
- </servlet-mapping>
- <servlet-mapping>
- <servlet-name>default</servlet-name>
- <url-pattern>*.js</url-pattern>
- </servlet-mapping>
- <welcome-file-list>
- <welcome-file>/index.jsp</welcome-file>
- </welcome-file-list>
- </web-app>
7.3 新建控制类controller及jsp页面之间交互
在这里使用jsp页面引入easyui集成并实现增删改查功能
userManage.jsp如下:
- <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
- <%
- String path = request.getContextPath();
- String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
- %>
- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
- <html>
- <head>
- <base href="<%=basePath%>">
- <title>My JSP 'userManage.jsp' starting page</title>
- <meta http-equiv="pragma" content="no-cache">
- <meta http-equiv="cache-control" content="no-cache">
- <meta http-equiv="expires" content="0">
- <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
- <meta http-equiv="description" content="This is my page">
- <link rel="stylesheet" type="text/css" href="jquery-easyui-1.5.1/themes/default/easyui.css">
- <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/jquery-easyui-1.5.1/themes/icon.css">
