Java-----SSM（SpringMVC+Spring+mybaties）框架整合
在进行整合之前，首先了解这个框架的作用
Mybaties：
丰富的标签库，可写动态sql，并统一的在.XML文件中编写，方便统一管理，解耦
SpringMVC：
标准的MVC思想（mode，view，controller），使代码的耦合性降低，方便实现ioc，方便代码的维护
Spring：
Spring的核心思想是IOC和AOP，ioc使代码耦合性低，便于维护。Aop方便事物和日志等管理。
aop：面向切面编程，横切关注点，通过预编译方式和运行期动态代理实现程序功能的统一维护的一种技术。主要功能是将程序中多个模块的事物日志等抽出来统一管理，使程序员专注开发，不需要管理其它的事情。
ioc：控制反转，将实例化对象的权利翻转了，原来new对象需要用户通过代码new，现在将权利交给spring容器来new。
项目整体结构：
1.首先在pom.xml中建立相关依赖

4.在resources下配置application-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</beans>
5.在java下新建包
6.在entity包下新建实体类User.java
package org.lpf.entity;
/**
* @author user:11963
* @version date：2017年12月12日 下午8:56:29
*
*/
public class User {
private int id;
private String name;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "User [id=" + id + ", name=" + name + ", password=" + password + "]";
} }
7.在mapper包下新建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="org.lpf.dao.UserDao"> <!-- 登录 -->
<select id="dologin" parameterType="org.lpf.entity.User" resultType="org.lpf.entity.User">
select * from user where name=#{name} and
password=#{password}
</select> </mapper>
8.在dao包下新建UserDao.java
package org.lpf.dao;
/**
* @author user:11963
* @version date：2017年12月12日 下午8:58:08
*
*/ import org.lpf.entity.User; public interface UserDao {
public User dologin(User user); }
9.在service下新建UserService.java
package org.lpf.service; import org.lpf.entity.User; /**
* @author user:11963
* @version date：2017年12月12日 下午9:09:26
*
*/
public interface UserService {
public User dologin(User user); }
10.在impl包下新建UserServiceImpl.java
package org.lpf.service.impl; import org.lpf.dao.UserDao;
import org.lpf.entity.User;
import org.lpf.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional; /**
* @author user:11963
* @version date：2017年12月12日 下午9:10:52
*
*/
@Service
@Transactional
public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao; @Override
public User dologin(User user) {
// TODO Auto-generated method stub
return this.userDao.dologin(user);
} }
11.在controller在新建UserController.java
package org.lpf.controller; import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession; import org.lpf.entity.User;
import org.lpf.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping; /**
* @author user:11963
* @version date：2017年12月12日 下午9:21:02
*
*/
@Controller
@RequestMapping("/user/")
public class UserController {
@Autowired(required=true)
private UserService service; public UserController() {
// TODO Auto-generated constructor stub
} @RequestMapping("login")
public String login(User user,HttpServletRequest request,HttpSession session){
System.out.print("!!!!!");
User users=new User();
users=service.dologin(user);
return "index";
} }
12.编写jsp：
login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
