2、jdbc.property文件

jdbc.driver=com.mysql.jdbc.Driver#数据库地址jdbc.url=jdbc:mysql://localhost:3306/ChatRobot?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false#用户名jdbc.username=root#密码jdbc.password=mysql#最大连接数c3p0.maxPoolSize=30#最小连接数c3p0.minPoolSize=10#关闭连接后不自动commitc3p0.autoCommitOnClose=false#获取连接超时时间c3p0.checkoutTimeout=10000#当获取连接失败重试次数c3p0.acquireRetryAttempts=2

3、log4j.property文件

#定义LOG输出级别log4j.rootLogger=INFO,Console,File#定义日志输出目的地为控制台log4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.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.Console.layout = org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=[%c] - %m%n#文件大小到达指定尺寸的时候产生一个新的文件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 = ALLlog4j.appender.File.layout = org.apache.log4j.PatternLayoutlog4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

4、spring-mvc.xml

5、spring-mybatis

6、web.xml

   
     
    
     ChatRobot
      
    
     ChatRobot_Alpha_0.0.1
      
      
        
     
      encodingFilter
         
     
      org.springframework.web.filter.CharacterEncodingFilter
         
           
      
       encoding
            
      
       UTF-8
          
       
      
        
     
      encodingFilter
         
     
      /*

       contextConfigLocation
            
      
       classpath:spring-*.xml
          
         
     
      1
         
     
      true
       
      
        
     
      SpringMVC
         
         
     
      /
       
      
        
     
      index.html
       
    
   

7、mapper文件的写法

   
   
       
            SELECT * FROM user WHERE id = #{id}        
            select* from user        
    
              insert into user(username, password, HeadImage)        values (#{username,jdbcType=VARCHAR},#{password,jdbcType=VARCHAR},#{HeadImage,jdbcType=VARCHAR})    
        
            select* from user where username = #{username,jdbcType=VARCHAR}    
   

8、dao包的写法

package com.chatRobot.dao;import com.chatRobot.model.User;import java.util.List;public interface IUserDao {    User selectUser(long id);    User getUser( String username);    List
   
     findAllUser();    int insertUser(User user);}
   

9、service包写法

package com.chatRobot.service;import com.chatRobot.model.TicketNumber;import com.chatRobot.model.User;import java.util.List;public interface IUserService {    public User selectUser(long userId);    public List
   
     findAllUser();   public int insertUser(User user);    public User getUser( String username);}
   

10、service接口的实现类IMPLService

package com.chatRobot.service.impl;import com.chatRobot.dao.IUserDao;import com.chatRobot.model.User;import com.chatRobot.service.IUserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import javax.annotation.Resource;import java.util.List;@Service("userService")public class UserServiceImpl implements IUserService {    @Autowired    private IUserDao userDao;    public User selectUser(long userId) {        return this.userDao.selectUser(userId);    }    public List
   
     findAllUser() {        return this.userDao.findAllUser();    }    public int insertUser(User user) {        return this.userDao.insertUser(user);    }    public User getUser(String username) {        return this.userDao.getUser(username);    }}
   

11、cotroller包的写法

package com.chatRobot.cotroller;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import com.alibaba.fastjson.JSONObject;import com.chatRobot.Uitils.ExceptionProject;import com.chatRobot.model.User;import com.chatRobot.service.IUserService;import org.apache.commons.fileupload.FileItem;import org.apache.commons.fileupload.disk.DiskFileItemFactory;import org.apache.commons.fileupload.servlet.ServletFileUpload;import org.codehaus.jackson.map.ObjectMapper;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import javax.annotation.Resource;import javax.servlet.http.HttpServletResponse;import java.io.File;import java.io.IOException;import java.util.ArrayList;import java.util.List;@Controller@RequestMapping("/user")public class UserController {    @Resource(name="userService")    private IUserService userService;    //登录接口    @RequestMapping("/LoginUser")    public @ResponseBody JSONObject LoginUser(HttpServletRequest request, HttpServletResponse response) throws IOException {                JSONObject results=new JSONObject();                String UserName=request.getParameter("username");                String password=request.getParameter("password");                User oldUsername=userService.getUser(UserName);                if( UserName!=null && oldUsername.getUsername().equals(UserName) ){                    results.put("message", ExceptionProject.successLogin);                    results.put("code",200);                    results.put("data",null);                    return results;                }else{                    results.put("message",ExceptionProject.faileLogin);                    results.put("code",200);                    results.put("data",null);                    return results;                }    }}

这样一个简单SSM框架就搭建完毕，dao写接口提供mabatis数据持久，service写接口-implservice去实现，，cotroller实现request的请求和response的响应返回。
