spring+springmvc+mybatis集成

一个核心：将对象交给spring管理。

1新建web项目

2添加项目jar包

spring包见上一篇博客

3建立项目的目录结构

4完成Mapper的集成

和mybatis进行集成，交给spring产生Mapper接口的代理对象。

4.1建立Mapper接口

1 package org.guangsoft.mapper; 2  3 import java.util.List; 4  5 import org.guangsoft.pojo.Privilege; 6  7 public interface PrivilegeMapper 8 { 9     public void addPrivilege(Privilege privilege);10     public void deletePrivilege(Privilege privilege);11     public void updatePrivilege(Privilege privilege);12     public Privilege selectPrivilegeById(Privilege privilege);13     public List
     
       selectAllPrivileges();14 }

4.2建立Mapper.xml文件

1 
      2  3 
     
       4      
      
        5          insert into privilege values(null,#{pname}) 6      
       7      
      
        8          delete from privilege 9      
      10      
      
       11          update privilege set pname=#{pname} where pid=#{pid}12      
      13      
      16      
      19

4.3建立application_mapper.xml

在config下建立：

配置数据库连接池。

管理SqlSessionFactory，注入DataSource

产生Mapper接口的代理对象。

5完成service的功能

5.1建立Service接口

1 package org.guangsoft.service; 2  3 import java.util.List; 4  5 import org.guangsoft.pojo.Privilege; 6  7 public interface PrivilegeService 8 { 9     public void addPrivilege(Privilege privilege);10     public void deletePrivilege(Privilege privilege);11     public void updatePrivilege(Privilege privilege);12     public Privilege selectPrivilegeById(Privilege privilege);13     public List
     
       selectAllPrivileges();14 }

5.2建立业务接口实现类

将实现类的对象纳入spring容器。注入Mapper接口的代理对象

1 package org.guangsoft.service.impl; 2  3 import java.util.List; 4  5 import org.guangsoft.mapper.PrivilegeMapper; 6 import org.guangsoft.pojo.Privilege; 7 import org.guangsoft.service.PrivilegeService; 8 import org.springframework.beans.factory.annotation.Autowired; 9 import org.springframework.stereotype.Service;10 11 @Service12 public class PrivilegeServiceImpl implements PrivilegeService13 {14     /**15      * 注入Mapper接口的代理对象16      */17     @Autowired18     private PrivilegeMapper privilegeMapper;19     20     @Override21     public void addPrivilege(Privilege privilege)22     {23         privilegeMapper.addPrivilege(privilege);24     }25 26     @Override27     public void deletePrivilege(Privilege privilege)28     {29         privilegeMapper.deletePrivilege(privilege);30     }31 32     @Override33     public void updatePrivilege(Privilege privilege)34     {35         privilegeMapper.updatePrivilege(privilege);36     }37 38     @Override39     public Privilege selectPrivilegeById(Privilege privilege)40     {41         return privilegeMapper.selectPrivilegeById(privilege);42     }43 44     @Override45     public List
     
       selectAllPrivileges()46     {47         return privilegeMapper.selectAllPrivileges();48     }49 50 }

5.3建立application_service.xml

扫描service包

事务配置

6完成Action的功能

6.1建立Handler处理器

1 package org.guangsoft.controller; 2  3 import org.guangsoft.pojo.Privilege; 4 import org.guangsoft.service.PrivilegeService; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.stereotype.Controller; 7 import org.springframework.web.bind.annotation.RequestMapping; 8  9 @Controller10 public class PrivilegeController11 {12     @Autowired13     private PrivilegeService privilegeService;14     //定义菜单项求求的方法15     @RequestMapping("/addPrivilege")16     public String addPrivilege(Privilege privilege)17     {18         privilegeService.addPrivilege(privilege);19         return "index.jsp";20     }21 }

6.2建立springmvc的配置文件

7配置web.xml

1 
      2 
     
       3   
      
        4

        classpath:application_*.xml
        6   
       7   
      
        8     
       
        org.springframework.web.context.ContextLoaderListener
        9   
      10   
      
       11     
       
        springmvc
       12     
       
        org.springframework.web.servlet.DispatcherServlet
       13     
       
        14       
        
         contextConfigLocation
        15       
        
         classpath:springmvc_servlet.xml
        16     
       17     
       
        1
       18   
      19   
      
       20     
       
        springmvc
       21     
       
        *.action
       22   
      23

8建立视图页面

1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 2 <% 3 String path = request.getContextPath(); 4 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 5 %> 6  7  8  9   10     11     My JSP 'index.jsp' starting page12     
     13
