上一篇介绍了怎么SSM框架怎么进行整合:点击打开链接


这一篇主要创建一个项目(只写登录功能),测试一下我们的整合流程;

整合SSM:

1.创建测试数据库:db_test_ssm(编码utf8)

/*Navicat MySQL Data TransferSource Server         : 本地Source Server Version : 50536Source Host           : localhost:3306Source Database       : db_test_ssmTarget Server Type    : MYSQLTarget Server Version : 50536File Encoding         : 65001Date: 2017-07-30 16:07:13*/SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for `user`-- ----------------------------DROP TABLE IF EXISTS `user`;CREATE TABLE `user` (  `uid` int(10) NOT NULL,  `uname` varchar(10) DEFAULT NULL,  `upassword` varchar(10) DEFAULT NULL,  PRIMARY KEY (`uid`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;-- ------------------------------ Records of user-- ----------------------------

2.在eclipse中创建一个web项目

项目结构如下:

3.导入jar包

在项目的WEB-INF/lib下导入jar包,之后,并且右击-->添加到构建路径

我的jar包可以在这儿下载:点击打开链接



4.创建配置文件(db.properties)

不知道是为什么,用db.properties配置的话,我的数据库总是连接不上。所以,我还是在配置文件中

在config目录下,创建db.properties

直接从我上一个博客中复制,并修改部分参数就可以了。

    driver=com.mysql.jdbc.Driver        url=jdbc:mysql://localhost:3306/db_test_ssm      username=root      password=1234  


5.创建log4j的配置文件,log4j.properties

如果对日志没有什么需求,这块可以不配置。

在config目录下,创建log4j.properties

直接从我上一个博客中复制,不需要任何修改



6.创建spring与mybatis整合的配置文件(spring-mybatis.xml)

在config目录下,创建spring-mybatis.xml

直接从我上一个博客中复制,并修改部分参数就可以了。

7.整合springMVC(创建spring-mvc.xml)

在config目录下,创建spring-mvc.xml

直接从我上一个博客中复制,并修改部分参数就可以了。

<?xml version="1.0" encoding="UTF-8"?>      <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util"            xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"          xmlns:jpa="http://www.springframework.org/schema/data/jpa" xmlns:mvc="http://www.springframework.org/schema/mvc"          xsi:schemaLocation="              http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd              http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd              http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd              http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd              http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd              http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd              http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">                         <!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->            <context:component-scan base-package="cn.com.controller" />                      <!-- 启动SpringMVC的注解功能 -->           <mvc:annotation-driven></mvc:annotation-driven>                    <!-- 如果需要其他的配置,可以在自行引入 -->      </beans>    

8.配置web.xml

如果eclipse提示报错,可以参考:点击打开链接

如果不报错,那就更好了

如果之前项目的配置都和我的一样,那么这里的web.xml的配置直接复制,不需要进行任何修改,如果有不同之处,请自行更改。

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE xml>  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instancehttp://www.springmodules.org/schema/cache/springmodules-cache.xsdhttp://www.springmodules.org/schema/cache/springmodules-ehcache.xsd"  xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">  <display-name>test_ssm</display-name>    <!-- Spring和mybatis的配置文件 -->      <context-param>          <param-name>contextConfigLocation</param-name>          <param-value>classpath:spring-mybatis.xml</param-value>      </context-param>      <!-- 编码过滤器 -->      <filter>          <filter-name>encodingFilter</filter-name>          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>                  <async-supported>true</async-supported>          <init-param>              <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>      <!-- Spring监听器 -->      <listener>          <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>          <servlet-name>SpringMVC</servlet-name>          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>          <init-param>              <param-name>contextConfigLocation</param-name>              <param-value>classpath:spring-mvc.xml</param-value>          </init-param>          <load-on-startup>1</load-on-startup>          <async-supported>true</async-supported>      </servlet>      <servlet-mapping>          <servlet-name>SpringMVC</servlet-name>          <!-- 此处可以可以配置成*.do,对应struts的后缀习惯 -->          <url-pattern>*.do</url-pattern>      </servlet-mapping>          <welcome-file-list>          <welcome-file>/index.jsp</welcome-file>      </welcome-file-list>      <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>



9.检查是否有缺漏

框架整合完之后,完整的项目结构图如下:



编写项目代码:

1.在数据库中插入一条测试数据

2.编写前台登录页面(index.jsp)

我这里主要使用,使用ajax发送请求

稍微解释一下:输入用户名和密码,点击登录,ajax就会向后台发送请求。


<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><!-- 使用ajax,需要引入jquery --><script type="text/javascript" src="js/jquery-1.9.1.min.js"></script><title>测试ssm框架</title></head><!--   script代码   --><script type="text/javascript">$(function(){var uname = $('#uname').val();var upassword = $("#upassword").val();$('#login').click(function(){$.ajax({url:'user/login.do',data:{uanme:uname,upassword:upassword},type:'post',async:false,success:function(data){//如果登录成功:弹出:登陆成功,否则:弹出失败alert(data);}});});});</script><body><!-- 前台页面 -->用户名:<input type="text" id="uname" name="uname"></input><br>密码:<input type="password" id="upassword" name="upassword"></input><br><button id="login" >login</button></body></html>

3.编写后台代码

各个类如下:


先说明一下:从上往下说:

0.user实体类

1.前台发送请求,找到LoginController

2.LoginController调用LoginServiceImpl

3.LoginServiceImpl调用ILoginDao

4.ILoginDao实现类使用Spring的自动代理实现

5.ILoginDao中的方法,必须对应loginMapper.xml中的id

6.loginMapper.xml中,写sql语句

7.测试

具体代码在下面:

3.0.User实体类

package cn.com.domain;public class User {private int uid;private String uname;private String upassword;public int getUid() {return uid;}public void setUid(int uid) {this.uid = uid;}public String getUname() {return uname;}public void setUname(String uname) {this.uname = uname;}public String getUpassword() {return upassword;}public void setUpassword(String upassword) {this.upassword = upassword;}}


3.1.LoginController 的代码

当我们使用@Resource的注解的时候,无法使用,也没有可以导入的包,怎么办?

那是因为@Resource的注解不是spring 的,而是tomcat的,具体设置参考:点击打开链接

package cn.com.controller;import javax.annotation.Resource;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import cn.com.service.impl.LoginServiceImpl;@Controller@RequestMapping("/user")public class LoginController {@Resourceprivate LoginServiceImpl loginService;@RequestMapping("/login.do")@ResponseBodypublic String execute(String uname,String upassword){String result = loginService.login(uname,upassword);//因为前台乱码,所以我在这里输出一下System.out.println(result);return result;}}



3.2.ILoginService的代码

package cn.com.service;public interface ILoginService {public String login(String uname,String upassword);}



3.3.LoginServiceImpl的代码

package cn.com.service.impl;import javax.annotation.Resource;import org.springframework.stereotype.Service;import cn.com.dao.ILoginDao;import cn.com.domain.User;import cn.com.service.ILoginService;@Servicepublic class LoginServiceImpl implements ILoginService{@Resourceprivate ILoginDao loginDao;public String login(String uname,String upassword) {User user=   loginDao.login(uname);if(upassword.equals(user.getUpassword())){return "登录成功";}return "登录失败";}}


3.4.ILoginDao的代码

package cn.com.dao;import cn.com.domain.User;public interface ILoginDao {public User login(String uname);}


3.5.loginMapper的代码

<?xml version="1.0" encoding="UTF-8" ?>  <!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"       "http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd"> <mapper namespace="cn.com.dao.ILoginDao"><select id="login" resultType="cn.com.domain.User">SELECT * from `user` WHERE uname =#{uname}</select></mapper>
