maven+springMVC+myBatis+mysql+junit+slf4j+logback示例代码总结

1. 创建Maven Project

2.创建文件夹和相应的文件,总体目录结构如下

3.编写配置文件们

pom.xml内容如下:这个配置文件是用来引入项目所需要的jar包的

    demo
  

config.properties内容如下:这个配置文件是用来配置数据库连接信息的

river=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8
username=root
password=root
initialSize=0
maxActive=20
maxIdle=20
minIdle=1
maxWait=60000

logback.xml内容如下:这个配置文件是用来配置日志的处理方式的

	
		

	
	
	
	
	
	
	
		
			%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{20} - %msg%n
		
	
	
	
	
		
          ERROR
          ACCEPT
          DENY
        
		${log_dir}/example_error.log
		
			${log_dir}/example_error.%d.log
			${maxHistory}
		
		
			%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{20} - %msg%n
			UTF-8
		
	
	
	
	
	
		
          INFO
        
		${log_dir}/example_error.log
		
			${log_dir}/example_error.%d.log
			${maxHistory}
		
		
			%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{20} - %msg%n
			UTF-8
		
	
		
	
	  
    	 
     	
	
     
	

spring-mvc.xml内容如下:这个文件是用来配置spring mvc的control所在的包和其他spring mvc相关信息

    
    
    
    
        
            
                text/html;charset=UTF-8
            
        
    
    
    
        
            
                 
            
        
    
    
    
        
        
    

    
    
        
        
        
        
        
        
    

spring-mybatis.xml内容如下:这个配置文件用于springmvc和mybatis的整合

web.xml:这个配置文件用于配置项目的全局信息

  Archetype Created Web Application
  
   
    
        contextConfigLocation
        classpath:spring-mybatis.xml
    
    
    
        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        true
        
            encoding
            UTF-8
        
    
    
        encodingFilter
        /*
    
    
    
    

    
    
        org.springframework.web.context.ContextLoaderListener
    
    
    
        org.springframework.web.util.IntrospectorCleanupListener
    
    
    
    
        SpringMVC
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:spring-mvc.xml
        
        
        1
        
        true
    
    
        SpringMVC
        
        
        *.htm
    
    
    
    	/WEB-INF/jsp/login.jsp
    
    
	

4.根据数据库生成model,mapper文件和相应的dao层

数据库信息如下:

参考我的这篇博客: mybatis如何自动生成实体类,映射文件以及对应的dao层 ,生成后将文件复制到相应的包下,目录如下

 TestUser.java:

package cn.edu.nankai.demo.model;

public class TestUser {
    private Integer uid;

    private String uname;

    private String udesc;

    public Integer getUid() {
        return uid;
    }

    public void setUid(Integer uid) {
        this.uid = uid;
    }

    public String getUname() {
        return uname;
    }

    public void setUname(String uname) {
        this.uname = uname == null ? null : uname.trim();
    }

    public String getUdesc() {
        return udesc;
    }

    public void setUdesc(String udesc) {
        this.udesc = udesc == null ? null : udesc.trim();
    }
}
 
  
 
  
 
  
 
  
 TestUserMapper.java: 
  
 
  
 
  
package cn.edu.nankai.demo.dao;

import cn.edu.nankai.demo.model.TestUser;

public interface TestUserMapper {
    int deleteByPrimaryKey(Integer uid);

    int insert(TestUser record);

    int insertSelective(TestUser record);

    TestUser selectByPrimaryKey(Integer uid);

    int updateByPrimaryKeySelective(TestUser record);

    int updateByPrimaryKey(TestUser record);
}
 
  
 TestUserMapper.xml: 
  
 
  



  
    
    
    
  
  
    uid, uname, udesc
  
  
    select 
    
    from test_user
    where uid = #{uid,jdbcType=INTEGER}
  
  
    delete from test_user
    where uid = #{uid,jdbcType=INTEGER}
  
  
    insert into test_user (uid, uname, udesc
      )
    values (#{uid,jdbcType=INTEGER}, #{uname,jdbcType=VARCHAR}, #{udesc,jdbcType=VARCHAR}
      )
  
  
    insert into test_user
    
      
        uid,
      
      
        uname,
      
      
        udesc,
      
    
    
      
        #{uid,jdbcType=INTEGER},
      
      
        #{uname,jdbcType=VARCHAR},
      
      
        #{udesc,jdbcType=VARCHAR},
      
    
  
  
    update test_user
    
      
        uname = #{uname,jdbcType=VARCHAR},
      
      
        udesc = #{udesc,jdbcType=VARCHAR},
      
    
    where uid = #{uid,jdbcType=INTEGER}
  
  
    update test_user
    set uname = #{uname,jdbcType=VARCHAR},
      udesc = #{udesc,jdbcType=VARCHAR}
    where uid = #{uid,jdbcType=INTEGER}
  

 
  
 
  
5.编写service和serviceImpl层
 
  
TestUserService.java:
 
  
 
  
package cn.edu.nankai.demo.service;

import cn.edu.nankai.demo.model.TestUser;

public interface TestUserService {
	
	int insert(TestUser record);
	
}
 
  

 TestUserServiceImpl.java: 
  
 
  
package cn.edu.nankai.demo.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import cn.edu.nankai.demo.dao.TestUserMapper;
import cn.edu.nankai.demo.model.TestUser;
import cn.edu.nankai.demo.service.TestUserService;

@Service("testUserService")
public class TestUserServiceImpl implements TestUserService {

	@Resource
	TestUserMapper testUserMapper;
	public int insert(TestUser record) {
		// TODO Auto-generated method stub
		return testUserMapper.insert(record);
	}

}
 
  
 6.编写页面login.htm: 
  
 
  
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>



  
    
    
    
    
	
	
	    
	
	
	

  
  
  
    This is my JSP page. 

    点我增加用户
  

 
  
 7.编写Controller 
  
  
 
  
8.运行结果
