spring相关概念及SSM框架在本文当中就不多述了，直接上干货！
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
[html] view plain copy
1. <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：
[java] view plain copy
1. package com.liuhai.eshop.dao;
2.
3. import java.util.List;
4. import java.util.Map;
5.
6. import com.liuhai.eshop.domain.User;
7. /**
8. * 用户DAO接口
9. * @author Administrator
10. *
11. */
12. public interface UserDao {
13. /**
14. * 用户登录
15. * @param user
16. * @return
17. */
18. public User login(User user);
19. /**
20. * 查询所有用户
21. * @return
22. */
23. public List<User> getAll();
24. /**
25. * 根据条件查询用户
26. * @param user
27. * @return
28. */
29. public User getUser(User user);
30. /**
31. * 删除用户
32. * @param user
33. * @return
34. */
35. public int delete(int id);
36. /**
37. * 更新用户
38. * @param user
39. * @return
40. */
41. public int update(User user);
42. /**
43. * 添加用户
44. * @param user
45. * @return
46. */
47. public int add(User user);
48. /**
49. * 用户查询
50. * @param map
51. * @return
52. */
53. public List<User> find(Map<String,Object> map);
54. /**
55. * 获取总记录数
56. * @param map
57. * @return
58. */
59. public Long getTotal(Map<String,Object> map);
60. /**
61. * 根据id查询用户
62. * @param id
63. * @return
64. */
65. public User getUserById(int id);
66. }
UserService.java 用户service层接口如下：
[java] view plain copy
1. package com.liuhai.eshop.service;
2.
3. import java.util.List;
4. import java.util.Map;
5. import com.liuhai.eshop.domain.User;
6.
7. public interface UserService {
8. public List<User> getAll();
9. public User getUser(User user);
10. public int delete(int id);
11. public int update(User user);
12. public int add(User user);
13. public List<User> find(Map<String,Object> map);
14. public Long getTotal(Map<String,Object> map);
15. public User getUserById(int id);
16. }
UserServiceImpl.java 用户service实现层如下：
[java] view plain copy
1. package com.liuhai.eshop.service.impl;
2.
3. import java.util.List;
4. import java.util.Map;
5.
6. import javax.annotation.Resource;
7.
8. import org.springframework.stereotype.Service;
9.
10. import com.liuhai.eshop.dao.UserDao;
11. import com.liuhai.eshop.domain.User;
12. import com.liuhai.eshop.service.UserService;
13. @Service(value="userService")
14. public class UserServiceImpl implements UserService {
15. private UserDao userDao;
16. @Resource
17. public void setUserDao(UserDao userDao) {
18. this.userDao = userDao;
19. }
20. @Override
21. public List<User> getAll() {
22. return userDao.getAll();
23. }
24.
25. @Override
26. public User getUser(User user) {
27. return userDao.getUser(user);
28. }
29.
30. @Override
31. public int delete(int id) {
32. return userDao.delete(id);
33. }
34.
35. @Override
36. public int update(User user) {
37. return userDao.update(user);
38. }
39.
40. @Override
41. public int add(User user) {
42. return userDao.add(user);
43. }
44.
45. @Override
46. public List<User> find(Map<String, Object> map) {
47. return userDao.find(map);
48. }
49.
50. @Override
51. public Long getTotal(Map<String, Object> map) {
52. return userDao.getTotal(map);
53. }
54. public User getUserById(int id){
55. return userDao.getUserById(id);
56. }
57. }
user实体类如下：
[java] view plain copy
1. package com.liuhai.eshop.domain;
2.
3. import java.io.Serializable;
4.
5. /**
6. * 用户实体
7. * @author Administrator
8. *
9. */
10. public class User implements Serializable{
11. private static final long serialVersionUID = 1L;
12. private Integer id;
13. private String userName;
14. private String password;
15. private Integer age;
16. private String trueName;
17. private String email;
18. private String phone;
19. private String roleName;
20. public Integer getId() {
21. return id;
22. }
23. public void setId(Integer id) {
24. this.id = id;
25. }
26.
27. public Integer getAge() {
28. return age;
29. }
30. public void setAge(Integer age) {
31. this.age = age;
32. }
33. public String getPassword() {
34. return password;
35. }
36. public void setPassword(String password) {
37. this.password = password;
38. }
39. public String getUserName() {
40. return userName;
41. }
42. public void setUserName(String userName) {
43. this.userName = userName;
44. }
45. public String getTrueName() {
46. return trueName;
47. }
48. public void setTrueName(String trueName) {
49. this.trueName = trueName;
50. }
51. public String getEmail() {
52. return email;
53. }
54. public void setEmail(String email) {
55. this.email = email;
56. }
57. public String getPhone() {
58. return phone;
59. }
60. public void setPhone(String phone) {
61. this.phone = phone;
62. }
63. public String getRoleName() {
64. return roleName;
65. }
66. <h1><a name="t8"></a> public void setRoleName(String roleName) {</h1> this.roleName = roleName;
67. }
68. }
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：
[html] view plain copy
1. <?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4. xmlns:aop="http://www.springframework.org/schema/aop"
5. xmlns:context="http://www.springframework.org/schema/context"
6. xmlns:tx="http://www.springframework.org/schema/tx"
7. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
8. http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
9. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
10. http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
11. <!-- 属性配置文件 -->
12. <context:property-placeholder location="classpath:jdbc.properties"/>
13. <!-- 组件扫描，指定spring管理哪些bean -->
14. <context:component-scan base-package="com.liuhai.eshop.dao.impl,com.liuhai.eshop.service.impl"></context:component-scan>
15.
16. <!-- 注解驱动 -->
17. <tx:annotation-driven/>
18. <!-- 创建数据源 -->
19. <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
20. <property name="driverClass" value="${jdbc.driverclass}"></property>
21. <property name="jdbcUrl" value="${jdbc.url}"></property>
22. <property name="user" value="${jdbc.username}"></property>
23. <property name="password" value="${jdbc.password}"></property>
24. <property name="initialPoolSize" value="${c3p0.pool.size.init}"></property>
25. <property name="minPoolSize" value="${c3p0.pool.size.min}"></property>
26. <property name="maxPoolSize" value="${c3p0.pool.size.max}"></property>
27. <property name="acquireIncrement" value="${c3p0.pool.size.increment}"></property>
28. </bean>
29. <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
30. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
31. <property name="dataSource" ref="dataSource" />
32. <!-- 自动扫描mapping.xml文件 -->
33. <property name="mapperLocations" value="classpath:com/liuhai/eshop/mappers/*.xml"></property>
34. </bean>
35. <!-- DAO接口所在包名，Spring会自动查找其下的类 -->
36. <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
37. <property name="basePackage" value="com.liuhai.eshop.dao"></property>
38. <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
39. </bean>
40. <!-- 事务管理器，service层面上实现事务管理的 -->
41. <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
42. <property name="dataSource" ref="dataSource"></property>
43. </bean>
44. </beans>
5.2 jdbc属性文件jdbc.properties如下：
[html] view plain copy
1. jdbc.driverclass=com.mysql.jdbc.Driver
2. jdbc.url=jdbc\:mysql\://localhost\:3306/eshop
3. jdbc.username=root
4. jdbc.password=123456
5. c3p0.pool.size.max=10
6. c3p0.pool.size.min=2
7. c3p0.pool.size.init=3
8. c3p0.pool.size.increment=2
9.
10. hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
11. hibernate.show_sql=true
12. hibernate.hbm2ddl.auto=none
5.3 日志属性文件log4j.properties如下：
[html] view plain copy
1. log4j.rootLogger=INFO,Console,File
2. #定义日志输出目的地为控制台
3. log4j.appender.Console=org.apache.log4j.ConsoleAppender
4. log4j.appender.Console.Target=System.out
5. #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
6. log4j.appender.Console.layout = org.apache.log4j.PatternLayout
7. log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
8.
9. log4j.logger.java.sql.ResultSet=INFO
10. log4j.logger.org.apache=INFO
11. log4j.logger.java.sql.Connection=DEBUG
12. log4j.logger.java.sql.Statement=DEBUG
13. log4j.logger.java.sql.PreparedStatement=DEBUG
14.
15. #文件大小到达指定尺寸的时候产生一个新的文件
16. log4j.appender.File = org.apache.log4j.RollingFileAppender
17. #指定输出目录
18. log4j.appender.File.File = logs/ssm.log
19. #定义文件最大大小
20. log4j.appender.File.MaxFileSize = 10MB
21. # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
22. log4j.appender.File.Threshold =INFO
23. log4j.appender.File.layout = org.apache.log4j.PatternLayout
24. 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）
[html] view plain copy
1. <?xml version="1.0" encoding="UTF-8"?>
2. <!DOCTYPE mapper
3. PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
4. "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
5. <mapper namespace="com.liuhai.eshop.dao.UserDao">
6. <!-- 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 -->
7. <cache size="1024" flushInterval="60000" eviction="LRU" readOnly="false"></cache>
8. <!-- 增加 -->
9. <insert id="add" parameterType="com.liuhai.eshop.domain.User">
10. insert into users values(null,#{userName},#{password},#{age},#{trueName},#{email},#{phone},#{roleName})
11. </insert>
12. <resultMap id="userResultMap" type="com.liuhai.eshop.domain.User" >
13. <id property="id" column="id"/>
14. <result property="userName" column="userName"/>
15. <result property="password" column="password"/>
16. <result property="age" column="age"/>
17. <result property="trueName" column="trueName" />
18. <result property="email" column="email" />
19. <result property="phone" column="phone" />
20. <result property="roleName" column="roleName" />
21. </resultMap>
22. <select id="getUserById" parameterType="Integer" resultMap="userResultMap">
23. select * from users where id=#{id}
24. </select>
25. <select id="find" parameterType="com.liuhai.eshop.domain.User" resultMap="userResultMap">
26. select * from users
27. <where>
28. <if test="userName!=null and userName!='' ">
29. and userName like #{userName}
30. </if>
31. </where>
32. <if test="start!=null and size!=null">
33. limit #{start},#{size}
34. </if>
35. </select>
36. <select id="getTotal" parameterType="Map" resultType="Long">
37. select count(*) from users
38. <where>
39. <if test="userName!=null and userName!='' ">
40. and userName like #{userName}
41. </if>
42. </where>
43. </select>
44. <!-- 用户删除 -->
45. <delete id="delete" parameterType="Integer">
46. delete from users where id = #{id}
47. </delete>
48. <!-- 用户修改 -->
49. <update id="update" parameterType="com.liuhai.eshop.domain.User">
50. update users
51. <set>
52. <if test="age != null and age != ''">age = #{age},</if>
53. <if test="userName != null and userName != ''">userName = #{userName},</if>
54. <if test="password != null and password != ''">password = #{password},</if>
55. <if test="trueName != null and trueName != ''">trueName = #{trueName},</if>
56. <if test="email != null and email != ''">email = #{email},</if>
57. <if test="phone != null and phone != ''">phone = #{phone},</if>
58. <if test="roleName != null and roleName != ''">roleName = #{roleName},</if>
59. </set>
60. where id = #{id}
61. </update>
62. </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：
[java] view plain copy
1. package com.liuhai.eshop;
2.
3. import org.junit.Test;
4. import org.springframework.context.ApplicationContext;
5. import org.springframework.context.support.ClassPathXmlApplicationContext;
6.
7. import com.liuhai.eshop.domain.User;
8. import com.liuhai.eshop.service.UserService;
9.
10. public class TestSpring {
11. @Test
12. public void TestUserService() throws Exception{
13. @SuppressWarnings("resource")
14. ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
15. UserService us=(UserService) ac.getBean("userService");
16. User user=new User();
17. user.setAge(1);
18. user.setUserName("zhangsan");
19. user.setPassword("123456");
20. user.setTrueName("张三");
21. us.add(user);
22. }
23. }
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
[html] view plain copy
1. <span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4. xmlns:context="http://www.springframework.org/schema/context"
5. xmlns:mvc="http://www.springframework.org/schema/mvc"
6. xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
7. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
8. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
9.
10. <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
11. <context:component-scan base-package="com.liuhai.eshop.controller"></context:component-scan>
12. <!--避免IE执行AJAX时，返回JSON出现下载文件 -->
13. <bean id="mappingJacksonHttpMessageConverter"
14. class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
15. <property name="supportedMediaTypes">
16. <list>
17. <value>text/html;charset=UTF-8</value>
18. </list>
19. </property>
20. </bean>
21. <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
22. <!-- 详细介绍：http://www.ibm.com/developerworks/cn/web/wa-restful/ -->
23. <bean
24. class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
25. <property name="messageConverters">

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。
[html] view plain copy

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：

分页Model类PageBean.java
[java] view plain copy
1. package com.liuhai.eshop.util;
2. /**
3. * 分页Model类
4. * @author Administrator
5. *
6. */
7. public class PageBean {
8. private int page; // 第几页
9. private int pageSize; // 每页记录数
10. private int start; // 起始页
11. public PageBean(int page, int pageSize) {
12. super();
13. this.page = page;
14. this.pageSize = pageSize;
15. }
16. public int getPage() {
17. return page;
18. }
19. public void setPage(int page) {
20. this.page = page;
21. }
22. public int getPageSize() {
23. return pageSize;
24. }
25. public void setPageSize(int pageSize) {
26. this.pageSize = pageSize;
27. }
28. public int getStart() {
29. return (page-1)*pageSize;
30. }
31. }
用于返回json数据ResponseUtil.java
[java] view plain copy
1. package com.liuhai.eshop.util;
2.
3. import java.io.PrintWriter;
4.
5. import javax.servlet.http.HttpServletResponse;
6. /***
7. * 主要用于返回json数据
8. * @author Administrator
9. */
10. public class ResponseUtil {
11. public static void write(HttpServletResponse response,Object object)throws Exception{
12. response.setContentType("text/html;charset=utf-8");
13. PrintWriter out=response.getWriter();
14. out.println(object);
15. out.flush();
16. out.close();
17. }
18. }
字符串工具类StringUtil.java如下:
[java] view plain copy
1. package com.liuhai.eshop.util;
