}

接口dao

package cn.zhc.dao;

public interface EmpInfoDao {
     
    public void addEmp();
}

实现类Impl

package cn.zhc.dao.Impl;

import cn.zhc.dao.EmpInfoDao;

public class EmpInfoDaoImpl implements EmpInfoDao {
     
    @Override
    public void addEmp() {
     
        System.out.println("迪丽迪丽热巴呀");
    }
}

Service层

package cn.zhc.service;

import cn.zhc.dao.EmpInfoDao;

public class EmpService {
     
    private EmpInfoDao empInfoDao;

    public EmpInfoDao getEmpInfoDao() {
     
        return empInfoDao;
    }

    public void setEmpInfoDao(EmpInfoDao empInfoDao) {
     
        this.empInfoDao = empInfoDao;
    }

    public void addEmp(){
     
        empInfoDao.addEmp();
    }
}

action层

package cn.zhc.action;

import cn.zhc.service.EmpService;

public class EmpAction {
     
    private EmpService empService;

    public EmpService getEmpService() {
     
        return empService;
    }

    public void setEmpService(EmpService empService) {
     
        this.empService = empService;
    }

    public String execute(){
     
        empService.addEmp();
        return null;
    }
}

测试类

package cn.zhc.test;

import cn.zhc.action.EmpAction;
import cn.zhc.domain.EmpInfo;
import cn.zhc.service.EmpService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
     
    public static void main(String[] args) {
     
        //test1();
        //test2();
        //test3();
        test4();
    }
    
    private static void test1() {
     
        ApplicationContext ac = new ClassPathXmlApplicationContext("spring.xml");
        EmpInfo empInfo= (EmpInfo) ac.getBean("empInfo");
        System.out.println(empInfo.getAddress().getHomeAddress());
    }

    private static void test2() {
     
        ApplicationContext ac = new ClassPathXmlApplicationContext("spring.xml");
        EmpService es = (EmpService) ac.getBean("empService");
        es.addEmp();
    }

    private static void test3() {
     
        ApplicationContext ac = new ClassPathXmlApplicationContext("spring.xml");
        EmpService es1 = (EmpService) ac.getBean("empService");
        EmpService es2 = (EmpService) ac.getBean("empService");
        System.out.println(es1==es2);
    }

    private static void test4() {
     
        ApplicationContext ac = new ClassPathXmlApplicationContext("spring.xml");
        EmpAction ea = (EmpAction) ac.getBean("empAction");
        ea.execute();
    }
}
