Spring MVC+Mybatis+Maven+Velocity+Mysql整合实例
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

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','[email protected]'),('2','dlm','1','0','[email protected]');
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"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

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

</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.csdn.net/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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>mybatis</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/applicationContext-user.xml</param-value> </context-param> <filter> <description>字符集过滤器</description> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <description>字符集编码</description> <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> <listener> <description>spring监听器</description> <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> <description>spring mvc servlet</description> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <description>spring mvc 配置文件</description> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!-- 配置session超时时间，单位分钟 --> <session-config> <session-timeout>15</session-timeout> </session-config> </web-app>
2.index.jsp
<script language="javascript"> window.location.href="userList.do"; </script>
3.相关vm文件
1）模板文件layout.vm
<html>
<head>
<title>Spring MVC and Velocity</title>
</head>
<body>
<h1>Spring MVC and Velocity</h1>
$screen_content
<hr />
Copyright © 2014 lm
</body>
</html>
2) list.vm
<h2>List of Feeds</h2>
<ul>
#foreach($user in $users)
<li><a href="user/${user.userId}">${user.email}</a></li>
#end
</ul>
3) detail.vm
<h2>Detail of Feed</h2>
<p>Id: ${user.userId}</p>
<p>Title: ${user.email}</p>
以上就是Spring mvc+mybatis+maven+velocity+mysql整合的所有内容
