Spring+SpringMVC+Mybatis简单配置和使用
之前做的项目一直使用SSM框架开发，用了几个月的SSM，个人感觉搭建起来比较简单也非常好用，之前自己也搭过小型的ssm但没记录下来，正好写ftp+nginx+fileinput的时候需要用到,所以又整理了一次就记录了下来。
SSM整合
一、配置文件
需要的JAR包
- 创建编写jdbc配置文件jdbc.properties
#JDBC Configure
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test
jdbc.username=root
jdbc.password=123456- 建立配置spring-mybatis文件

web-app>- 建立配置日志记录文件log4j.properties
log4j.rootLogger=INFO,Console,File
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
log4j.appender.File = org.apache.log4j.RollingFileAppender
log4j.appender.File.File = logs/ssm.log
log4j.appender.File.MaxFileSize = 10MB
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n 关于上面的几个配置文件可以参照博文http://blog.csdn.net/mrslw/article/details/52824145的详细介绍，上面每个配置的功能介绍是比较详细的。
二、功能编写
上面的配置文件配置好后接下来就做一个简单的用户登录系统
建立的文件结构：
User.java文件:
package com.xw.demo.domain;
import java.io.Serializable;
public class User implements Serializable {
private static final long serialVersionUID = -5383127837792395250L;
//用户ID
private Integer id;
//用户名
private String username;
//用户密码
private String password;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
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;
}
}UserMapper代码：
<mapper namespace="com.xw.demo.dao.UserDao">
<resultMap type="com.xw.demo.domain.User" id="UserMap">
<id column="id" property="id" />
<result column="username" property="username" />
<result column="password" property="password" />
resultMap>
<select id="selectByUsername" resultMap="UserMap" parameterType="String" resultType="com.xw.demo.domain.User">
SELECT * FROM TB_USER WHERE USERNAME = #{username};
select>
mapper>
UserDao代码：
package com.xw.demo.dao;
import com.xw.demo.domain.User;
public interface UserDao {
/**
* 根据用户名查询
* @param username 用户名
* @return
*/
public User selectByUsername(String username);
}
UserService代码：
package com.xw.demo.service;
import com.xw.demo.domain.User;
public interface UserService {
/**
* 根据用户名查询
* @param username 用户名
* @return
*/
public User selectByUsername(String username);
}
UserServiceImpl代码：
package com.xw.demo.service.impl;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.xw.demo.dao.UserDao;
import com.xw.demo.domain.User;
import com.xw.demo.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService {
@Resource
private UserDao userDao;
/**
* 根据用户名查询
* @param username 用户名
* @return user 用户集合
*/
public User selectByUsername(String username) {
User user = userDao.selectByUsername(username);
return user;
}
}登录页面：
代码：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>用户登录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">

head>
<body>
<div style="padding: 300px 100px 10px;" align="center">
<form class="bs-example bs-example-form" name="login_form" id="login_form">
<div class="input-group">
<span class="input-group-addon" style="width:67px;">用户名span>

div>
body>
<script type="text/javascript">
$(function() {
$("#login_btn").click(function(){
$("#login_form").submit();
});
$("#login_form").ajaxForm({
url:"/SSM/user/loginCheck",
dataType:"json",
type:"post",
success:function(data){
alert(data.message);
}
});
});
script>
html>
Controller层编写
package com.xw.demo.controller;
import java.util.HashMap;
import java.util.Map;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import com.xw.demo.domain.User;
import com.xw.demo.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Resource
private UserService userService;
private final static String LOGIN_PAGE = "/login";
@RequestMapping(value = "/login",method=RequestMethod.GET)
public String tologin(){
return LOGIN_PAGE;
}
@RequestMapping(value = "/loginCheck", method = RequestMethod.POST)
@ResponseBody
public Map login(String username,String password){
Map map = new HashMap();
User user = userService.selectByUsername(username);
if(user != null && user.getPassword().equals(password)){
map.put("message", "登陆成功!");
}else{
map.put("message", "用户名或者密码错误!");
}
return map;
}
}
三、功能测试
输入正确的用户名和密码：
输入错误的用户名和密码：
到这里整个SSM环境下的登录验证就完成了。
