[框架]eclipse搭建ssm框架一

虽然现在也做过一些项目，但是自己从头搭起来的框架几乎没有，所以这两天自己搭了一下ssm的框架，下面写一下框架的搭建过程。并且给出增删改查四条线来方便大家熟悉代码。

## 环境准备 ##

maven3.2.3  
eclipse luna Service Release（4.4.1）  
jdk 1.7  
tomcat7.0.40  
我们需要的工具就是这些，版本影响其实不太大。

## 配置 ##

一般来说，tomcat ，jdk ，maven一起配置就可以。windows->preferences->Server配置tomcat，顺便配置jdk，如图  
![这里写图片描述][SouthEast]  
![这里写图片描述][SouthEast 1]  
到此步，tomcat配置完成  
下面配置maven，选择菜单windows->preferences->Maven->User Settings,具体看自己的配置文件，将配置文件和maven文件夹都设置好，如图  
![这里写图片描述][SouthEast 2]

## 新建maven项目 ##

File->New->Maven Project 新建一个maven项目  
![这里写图片描述][SouthEast 3]  
选择文件夹  
![这里写图片描述][SouthEast 4]  
选择webapp，如果刚到这个页面不现实下面这些，把catalog选项换成Internal  
![这里写图片描述][SouthEast 5]  
给项目起个名字  
![这里写图片描述][SouthEast 6]

最后，还有个index.jsp报错，我们需要引入Java EE的jar包即可。在pom.xml中引入：

<dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-api</artifactId>  
            <version>7.0</version>  
        </dependency>

到现在为止，  
一个maven项目就搭建完成了。

## 引入jar包 ##

我们需要引入的jar包包括以下几种  
spring核心包  
mybatis核心包  
spring-mybatis整合包  
mysql连接包  
jstl标签类  
日志包  
json解析包  
下面是pom文件的内容

## 整合spring-mybatis ##

### jdbc.properties ###

这个文件配置连接数据库的参数赋值等。

        log4j.appender.Console=org.apache.log4j.ConsoleAppender  
        log4j.appender.Console.Target=System.out  
        #可以灵活地指定日志输出格式，下面一行是指定具体的格式

        log4j.appender.File = org.apache.log4j.RollingFileAppender  
        #指定输出目录  
        log4j.appender.File.File = logs/ssm.log  
        #定义文件最大大小  
        log4j.appender.File.MaxFileSize = 10MB  
        # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志  
        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

到此为止，spring和mybatis的整合就完成了，下面做springmvc的整合。

以上配置文件的路径如图：

需要注意的是，spring-mybatis和spring-mvc这两个配置文件里面涉及到路径的要改成自己的实际路径，不然会报错。

## 测试 ##

框架搭建完成，然后我们连接数据库测试一下，下面是数据库创建语句

DROP TABLE IF EXISTS `user_t`;
    CREATE TABLE `user_t` (
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `user_name` varchar(40) NOT NULL,
      `password` varchar(255) NOT NULL,
      `age` int(4) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB AUTO_INCREMENT=125556 DEFAULT CHARSET=utf8;
    
    -- ----------------------------
    -- Records of user_t
    -- ----------------------------
    INSERT INTO `user_t` VALUES ('12', '123', '123', '14');
    INSERT INTO `user_t` VALUES ('123', 'test', '123', '13');
    INSERT INTO `user_t` VALUES ('11111', 'zahgnsan', '123', '23');
    INSERT INTO `user_t` VALUES ('123456', 'username', '12id', '34');
    INSERT INTO `user_t` VALUES ('125555', '123', '123', '14');

建表成功以后，我们使用mybatis的插件来生成接口和mapper的代码，可以参考这个博客：  
[http://blog.csdn.net/zhshulin/article/details/23912615][http_blog.csdn.net_zhshulin_article_details_23912615]  
生成之后将文件拷贝到我们的目录下，如图：  
![这里写图片描述][SouthEast 8]

然后我们从前台到后台写一条线，先写一个查询。敲之前记得先把maven更新一下。

## IUserService.java ##

package com.cn.ssm.service;
    
    import com.cn.ssm.pojo.User;
    
    public interface IUserService {
    
        public User getUserById(int userId);
    
    }

## UserServiceImpl.java ##

package com.cn.ssm.service.impl;
    import javax.annotation.Resource;
    import javax.transaction.Transactional;
    import org.springframework.stereotype.Service;
    import com.cn.ssm.dao.UserMapper;
    import com.cn.ssm.pojo.User;
    import com.cn.ssm.service.IUserService;
    
    @Service
    @Transactional
    public class UserServiceImpl implements IUserService {
    
        @Resource
        public UserMapper userMapper;
    
        public User getUserById(int userId) {
            // TODO Auto-generated method stub
    
            return this.userMapper.selectByPrimaryKey(userId);
        }
    
    }

## UserController.java ##

package com.cn.ssm.controller;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpServletRequest;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import com.cn.ssm.pojo.User;
    import com.cn.ssm.service.IUserService;
    
    @Controller
    @RequestMapping("/user")
    public class UserController {
    
        @Resource
        private IUserService userService;
    
        @RequestMapping("userShow")
        public String toIndex(HttpServletRequest request,Model model){
            int userId = Integer.parseInt(request.getParameter("id"));
    
            User user = userService.getUserById(userId);
    
            model.addAttribute("user", user);
    
            return "showUser";
        }
    
    }

## showUser.jsp ##

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>  
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
    <html>  
      <head>  
        <title>测试</title>  
      </head>  
    
      <body>  
        ${user.userName}  
      </body>  
    </html>

## 显示 ##

启动tomcat，然后在浏览器的地址栏输入[http://localhost:8080/ssm/user/userShow?id=12][http_localhost_8080_ssm_user_userShow_id_12]  
将ssm改成你的项目名称。  
显示如图：

搭建这个框架，我基本上是参照这个博客来做的，因为觉得应该总结一下自己这两天的成功，所以写了这篇博客，不过大部分代码和原博客一样，所以大家可以去看看原博客，写的超级好。附链接：[http://blog.csdn.net/zhshulin/article/details/37956105/][http_blog.csdn.net_zhshulin_article_details_37956105]  
谢谢。
