利用SSM搭建web项目

下面给大家介绍一下，ssm的搭建和使用，7步搞定框架搭建

SSM所需要的jar包下载地址：http://download.csdn.net/download/baidu_32492845/10126554

1，创建数据库

DROP TABLE IF EXISTS `userinformation`;
CREATE TABLE `userinformation` (
  `id` int(100) NOT NULL AUTO_INCREMENT,
  `name` varchar(100) DEFAULT NULL,
  `password` varchar(100) DEFAULT NULL,
  `other` varchar(200) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

2，创建Javaweb项目，如下图所示，先建立几个必要的包

config-用来装配置文件；controller-用来装controller文件；domain-用来装实体类；mapper-用来装DAO文件，service-服务层文件；

3，建立创建controller类，domain实体类，DAO的mapper接口和xml文件，service类，只是创建，里面的代码下面会告诉大家怎么写，如下图所示

4，将ssm框架需要用到的jar包copy到WebRoot下面的WEB-INF下面的lib中，如图

5，开始写框架配置文件

1）在config包下面创建一个mybatis-config.xml文件，也就是DAO层的配置文件，文件代码如下

2）下面再在WebRoot下面的WEB-INF下面中创建一个applicationContext.xml,是用来配置spring的，代码如下

3）再在WebRoot下面的WEB-INF下面创建一个配置文件mvc-config.xml，是配置controller层的，代码如下

4）配置web.xml文件，代码如下

	
	
		org.springframework.web.context.ContextLoaderListener
	

	
	
		contextConfigLocation
		/WEB-INF/applicationContext.xml
	

	
	
		springMVC
		org.springframework.web.servlet.DispatcherServlet

		
			contextConfigLocation
		    /WEB-INF/mvc-config.xml
		
		
		1
	

	
	
		springMVC
		
		/
	

	
	
		org.springframework.web.util.IntrospectorCleanupListener
	

	
	
		encodingFilter
		org.springframework.web.filter.CharacterEncodingFilter
		
			encoding
			UTF-8
		
		
			forceEncoding
			true
		
	

	
		encodingFilter
		/*
	

	
		index.jsp
	

6，配置文件写好了，下面开始写代码

1)domain实体类的User.java

package com.test.domain;

public class User {
	private int id;
	private String name;
	private String password;
	private String other;

	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;
	}

	public String getOther() {
		return other;
	}

	public void setOther(String other) {
		this.other = other;
	}

}

2)DAO层UserMapper.java

package com.test.mapper;

import java.util.List;

import com.test.domain.User;

public interface UserMapper {

	List findAllUser();

}

3)DAO层UserMapper.xml

    
    
    
    	
    	
    	
    	
    
    
    
    	select * from userInformation
    
 

4）service层的UserService.java

package com.test.service;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.test.domain.User;
import com.test.mapper.UserMapper;

@Service
public class UserService {

	@Resource
	private UserMapper userMapper;

	public List getAllUser() {
		List list = userMapper.findAllUser();
		return list;
	}
}

5)controller层的UserController.java

package com.test.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.test.domain.User;
import com.test.service.UserService;

@Controller
@RequestMapping("/UserController")
public class UserController {

	@Resource
	private UserService userService;

	@RequestMapping("/getAllUser")
	public String getAllUser(String message, Model model) {
		System.out.println("============message===============:" + message);
		List list = userService.getAllUser();
		model.addAttribute("userList", list);
		return "list";
	}

}

6)index.jsp  访问项目的首页

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>



  
    
    
    
	
	
	    
	
	
	
  
  
  
    

    	
    	
    
  

7)lits.jsp  用来显示所有user的

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://" + request.getServerName() + ":"
			+ request.getServerPort() + path + "/";
%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>


	
		

		

		
		
		
		
		


	

	
		
					

			

				

					

						id
					
					

						name
					
					

						password
					
					

						other
					
				

				

						

							${list.id }
						
						

							${list.name }
						
						

							${list.password }
						
						

							${list.other }
						
					
				

			
		
	

7，运行web项目，在浏览器输入：localhost:端口号默认8080/项目名字/index.jsp，我的是： localhost:8090/TTestSSM/index.jsp，记得数据库要启动起来

下面是项目首页index.jsp

点击提交，出现下面list.jsp界面

好了，整个SSM项目到这里就搭建完成了。

最后可以下载完整版ssm的demo
