本篇文章将通过一个简单显示用户信息的实例整合Spring mvc+mybatis+Maven+velocity+mysql.

对于实现整合的重点在于以下几个配置文件的实现

1.Maven依赖包

2.spring配置文件(springContext-user.xml)

3.mybatis配置文件(MyBatis-User-Configuration.xml)

4.spring-mvc配置文件(spring-mvc.xml)

5.web.xml配置文件

源码下载地址：http://download.youkuaiyun.com/detail/a123demi/8398665

一、.Maven工程目录

二、Spring mvc + mybatis +maven实现

1.Mysql数据库表数据

CREATE TABLE `user` (
  `userId` varchar(20) NOT NULL,
  `userName` varchar(20) DEFAULT NULL,
  `password` varchar(20) DEFAULT NULL,
  `sex` char(1) DEFAULT '0',
  `email` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`userId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

/*Data for the table `user` */

insert  into `user`(`userId`,`userName`,`password`,`sex`,`email`) values ('1','lm','1','1','aaaaaa@126.com'),('2','dlm','1','0','bbbbbb@qq.com');

2.Maven依赖引入(pom.xml)

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.实体类UserEntity.java

package com.lm.entity;

public class UserEntity {
	private String userId;
	private String userName;
	private String password;
	private String sex;
	private String email;
	public String getUserId() {
		return userId;
	}
	public void setUserId(String userId) {
		this.userId = userId;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	@Override
	public String toString() {
		return "UserEntity [userId=" + userId + ", userName=" + userName
				+ ", password=" + password + ", sex=" + sex + ", email="
				+ email + "]";
	}
	
	
	
}

4.业务逻辑接口(Service)

package com.lm.service;

import java.util.List;

import com.lm.entity.UserEntity;


public interface UserService {

	UserEntity getUserEntityById(String userId);
	
	List<UserEntity> getUserEntities();
	
	UserEntity insertUserEntity(UserEntity userEntity);
}

说明：1.根据用户id获取用户信息

2.获取所有的用户信息

3.插入用户信息

5.接口实现(ServiceImpl)

package com.lm.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import com.lm.entity.UserEntity;
import com.lm.mapping.UserMapper;
import com.lm.service.UserService;

public class UserServiceImpl implements UserService {
	@Autowired
	private UserMapper userMapper;

	public UserMapper getUserMapper() {
		return userMapper;
	}

	public void setUserMapper(UserMapper userMapper) {
		this.userMapper = userMapper;
	}

	@Override
	public UserEntity getUserEntityById(String userId) {
		return this.userMapper.getUserEntityById(userId);
	}

	@Override
	public List<UserEntity> getUserEntities() {
		return this.userMapper.getUserEntities();
	}

	@Override
	public UserEntity insertUserEntity(UserEntity userEntity) {
		this.userMapper.insertUser(userEntity);

		return getUserEntityById(userEntity.getUserId());
	}

}

6.具体操作数据库接口(mapper)

<?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.lm.mapping.UserMapper">
	<resultMap id="userEntityMapper" type="UserEntity">
		<id property="userId" column="userId" />
		<result property="userName" column="userName" />
		<result property="password" column="password" />
		<result property="sex" column="sex" />
		<result property="email" column="email" />
	</resultMap>
	
	<select id="getUserEntityById" parameterType="String" resultMap="userEntityMapper">
		select * from user where userid=#{param1}   
	</select>
	
	<select id="getUserEntities" resultMap="userEntityMapper">
		select * from user 
	</select>
	
	<insert id="insertUser" parameterType="userEntity">
		insert into user(userId,userName,password,sex,email) 
		values(#{userEntity.userId},#{userEntity.userName},#{userEntity.password},#{userEntity.sex},#{userEntity.email})
	</insert>
	
</mapper>

说明：mybatis的简单用法

package com.lm.mapping;

import java.util.List;

import com.lm.entity.UserEntity;

public interface UserMapper {
	
	UserEntity getUserEntityById(String userId);
	
	List<UserEntity> getUserEntities();
	
	int insertUser(UserEntity userEntity);
}

7.Spring+mybatis+Spring mvc配置文件

1）spring配置文件(applicationContext-user.xml)

</beans>

2)mybatis配置文件(MyBatis-User-Configuration.xml)

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

	</settings>
	<typeAliases>
		<typeAlias alias="UserEntity"
			type="com.lm.entity.UserEntity" />

	</typeAliases>
</configuration>

3）Spring mvc 配置文件(引入velocity相关配置spring-mvc.xml)

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

	<!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
	<context:component-scan base-package="com.lm.controller" />

	<!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
	<bean id="mappingJacksonHttpMessageConverter"

		<property name="maxInMemorySize"> <value>4096</value> </property> </bean> -->

</beans>

8.数据库和log4j配置

1)数据库配置jdbc.properties

#mysql
mysql.driverClassName=com.mysql.jdbc.Driver
mysql.url=jdbc:mysql://localhost:3306/test
mysql.username=root
mysql.password=123

2)log4j日志配置

log4j.rootLogger=DEBUG,console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%p] %c#%M %x: %m%n

log4j.logger.com.ibatis=DEBUG 
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG 
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG 
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG 
log4j.logger.java.sql.Connection=DEBUG 
log4j.logger.java.sql.Statement=DEBUG 
log4j.logger.java.sql.PreparedStatement=DEBUG

9.控制层Controller（UserController.java）

package com.lm.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import com.lm.entity.UserEntity;
import com.lm.service.UserService;

@Controller
public class UserController {

	private UserService userService;

	public UserService getUserService() {
		return userService;
	}

	@Autowired
	public void setUserService(UserService userService) {
		this.userService = userService;
	}
	
	//http://localhost:8085/user_cms/userController/1/showUser.do
	@RequestMapping("/{id}/showUser")
	public String showUser(@PathVariable String id, ModelMap modelMap ,HttpServletRequest request) {
		UserEntity u = userService.getUserEntityById(id);
	
		if(u == null){
			u = new UserEntity();
			u.setEmail("");
			u.setUserId("");
		}
		modelMap.put("user", u);
		return "showUser";
	}
	
	//http://localhost:8085/user_cms/userController/showUser.do?id=1
	@RequestMapping("showUser")
	public String showUserEntity(String id, ModelMap modelMap,HttpServletRequest request) {
		UserEntity u = userService.getUserEntityById(id);
		if(u == null){
			u = new UserEntity();
			u.setEmail("");
			u.setUserId("");
		}
		modelMap.put("user", u);
		return "showUser";
	}
	
	@RequestMapping("/showUserExample")
	public String showUsers(Model model){
		return "redirect:/1/showUser.do";
	}
	
    @RequestMapping("/userList")
    public String list(ModelMap model) {
        model.put("users", userService.getUserEntities());
        return "list";
    }
    
    @RequestMapping("/user/{id}")
    public String detail(@PathVariable(value = "id") String id, ModelMap model) {
        model.put("user", userService.getUserEntityById(id));
        return "detail";
    }

}

说明：@RequestMapping的具体用法可以参考http://blog.youkuaiyun.com/lufeng20/article/details/7598801

三、前端相关配置

1.web.xml配置

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
