一.项目的整体目录结构


二.构建Maven项目



三、pom文件

四、web.xml的配置，包括字符集的设置，Springmvc的分发器的配置，加载Spring文件

[html]  view plain  copy
  1. <?xml version="1.0" encoding="UTF-8"?>    
  2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  53.     </welcome-file-list>    
  54.     
  55. </web-app>    

五.在rousources建立相关的配置文件

5.1 数据库的信息配置（注意不能有空格）

[html]  view plain  copy
  1. jdbc.driver=com.mysql.jdbc.Driver  
  2. jdbc.url=jdbc:mysql://127.0.0.1/websocket  
  3. jdbc.username=root  
  4. jdbc.password=123456  

5.2 日志信息配置

[html]  view plain  copy
  1. #\u5B9A\u4E49LOG\u8F93\u51FA\u7EA7\u522B    
  2. log4j.rootLogger=INFO,Console,File    
  3. #\u5B9A\u4E49\u65E5\u5FD7\u8F93\u51FA\u76EE\u7684\u5730\u4E3A\u63A7\u5236\u53F0

  7. log4j.appender.Console.layout = org.apache.log4j.PatternLayout    
  8. log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n    
  9.

  11. log4j.appender.File = org.apache.log4j.RollingFileAppender    
  12. #\u6307\u5B9A\u8F93\u51FA\u76EE\u5F55    
  13. log4j.appender.File.File = logs/ssm.log    
  14. #\u5B9A\u4E49\u6587\u4EF6\u6700\u5927\u5927\u5C0F

  17. log4j.appender.File.Threshold = ALL    
  18. log4j.appender.File.layout = org.apache.log4j.PatternLayout    
  19. log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n   


5.3 SpringMVC的配置，主要包括控制器的扫描路径，视图的配置，上传配置等

  23.     }  
  24.

6.2 dao层 采用xml配置方式

[java]  view plain  copy
  1. package com.yuanjun.dao;  
  2.   
  3. import java.util.List;  
  4.   
  5. import com.yuanjun.bean.Person;  
  6.   
  7. public interface PersonDao {  
  8.   
  9.     List<Person> findall();   
  10.   
  11. }  

注意对应关系 namespace对象dao接口，id对应接口对应的方法，resultType返回的实体类

[html]  view plain  copy
  1. <?xml version="1.0" encoding="UTF-8" ?>  
  2. <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >  
  3. <mapper namespace="com.yuanjun.dao.PersonDao" >  
  4.   <select id="findall" resultType="com.yuanjun.bean.Person">  
  5.      select id,name,password from person  
  6.   </select>  
  7.     
  8. </mapper  

6.3 Service层

[java]  view plain  copy
  1. package com.yuanjun.service;  
  2.   
  3. import java.util.List;  
  4.   
  5. import com.yuanjun.bean.Person;  
  6.   
  7. public interface PersonService {  
  8.       
  9.     List<Person> findAll();  
  10.       
  11. }     

[java]  view plain  copy
  1. package com.yuanjun.service;  
  2.   
  3. import java.util.List;  
  4.   
  5. import org.springframework.beans.factory.annotation.Autowired;  
  6. import org.springframework.stereotype.Service;  
  7.   
  8. import com.yuanjun.bean.Person;  
  9. import com.yuanjun.dao.PersonDao;  
  10. @Service  
  11. public class PersonServiceImpl implements PersonService {  
  12.       
  13.     @Autowired  
  14.     private PersonDao personDao;  
  15.       
  16.     public PersonDao getPersonDao() {  
  17.         return personDao;  
  18.     }  
  19.   
  20.     public void setPersonDao(PersonDao personDao) {  
  21.         this.personDao = personDao;  
  22.     }  
  23.   
  24.     public List<Person> findAll() {  
  25.         return personDao.findall();  
  26.     }  
  27.   
  28. }  

6.4 控制层

[java]  view plain  copy
  1. package com.yuanjun.control;  
  2.   
  3. import java.util.List;  
  4.   
  5. import org.springframework.beans.factory.annotation.Autowired;  
  6. import org.springframework.stereotype.Controller;  
  7. import org.springframework.web.bind.annotation.RequestMapping;  
  8.   
  9. import com.yuanjun.bean.Person;  
  10. import com.yuanjun.service.PersonService;  
  11.   
  12. @Controller  
  13. public class LoginControl {  
  14.     @Autowired  
  15.     private PersonService personService;  
  16.       
  17.     @RequestMapping("/main")  
  18.     public String test(){  
  19.           
  20.         List<Person> list = personService.findAll();  
  21.         for (Person person : list) {  
  22.             System.out.println(person);  
  23.         }  
  24.         return "main";  
  25.     }  
  26. }  



已成功的跳转，并且在控制台打印出相应的数据库信息，完成SSM的框架的整合，
