整合mybatis和spring，配置spring注解

首先看工程目录：

接下来分别看每个文件：

pom.xml

					**/*.properties
					**/*.xml
				
			
			
				src/main/java

注意最后的, 使maven 打包source文件夹下面的 xml等配置文件

web.xml文件：

	lmcdemo2
	
		contextConfigLocation
		classpath*:applicationContext.xml
	
	
	
		characterEncodingFilter
		org.springframework.web.filter.CharacterEncodingFilter
		
			encoding
			UTF-8
		
		
			forceEncoding
			true
		
	
	
		characterEncodingFilter
		/*
	
	
	
		org.springframework.web.context.ContextLoaderListener
	
	
		mvcServlet
		org.springframework.web.servlet.DispatcherServlet
		
		contextConfigLocation
		classpath*:/servlet-context.xml
		
		1
	
	
	
	mvcServlet
	*.action
	
	

servlet-context.xml文件：

MyBatis-Configuration.xml文件：

UserDaoMapper.xml文件：

  
 

    
        select count(*) as c from userinfo;
    

applicationContext.xml文件：

UserDao.java文件：

package lmcdemo.dao;
public interface UserDao {
    public int countAll();
}

UserService.java文件：

package lmcdemo.services;

public interface UserService {
    public int countAll();
}

UserServiceImpl.java文件：

package lmcdemo.services.impl;

import lmcdemo.dao.UserDao;
import lmcdemo.services.UserService;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository
@SuppressWarnings("rawtypes")
public class UserServiceImpl implements UserService{
	@Autowired
    private UserDao userDao;

    public UserDao getUserDao() {
        return userDao;
    }
    
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
    
    public int countAll() {
        return this.userDao.countAll();
    }
}

UserController.java测试文件：

package lmcdemo.controller;

import lmcdemo.services.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;


@Controller
@RequestMapping("/user")
public class UserController {
	@Autowired
	private UserService userInfoSerivce;

	@ResponseBody
	@SuppressWarnings("rawtypes")
	@RequestMapping(value = "/userlist")
	public String userlist(String test,int count) {
		int a=userInfoSerivce.countAll();
		return String.valueOf(a)+test+String.valueOf(count);
	}
}

http://localhost:8080/lmcdemo2/user/userlist.action?test=oracle&count=88

Helloworld.java测试文件：

package lmcdemo.controller;
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/helloworld")
public class Helloworld {
    @RequestMapping(method=RequestMethod.GET)
    public ModelAndView hello() {
        ModelAndView mv = new ModelAndView();
        mv.setViewName("helloworld");
        return mv;
    }
}

http://localhost:8080/lmcdemo2/helloworld.action

main.java测试文件：

package lmcdemo;

import lmcdemo.services.UserService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class main {
	
	public static void main(String[] args) {
		  ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
	        UserService userService = (UserService)context.getBean("userService");
	        System.out.println(userService.countAll());
		
	}

}
