注解引用:1.service.xml 配置注解模式
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> <!--将针对注解的处理器配置好 --> <context:annotation-config /> <context:component-scan base-package="*.*"/> </beans>
2.UserService.java
使用@Service 命名该类的name
使用@Controller("userService") 效果也是一样
如果单使用@Controller 那么命名就只能用userService 这样的驼峰
package com.sun.service; import java.util.ArrayList; import javax.annotation.Resource; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @Service("userservice") public class UserService { private String name; private ArrayList arr; public ArrayList getArr() { return arr; } public void setArr(ArrayList arr) { this.arr = arr; } public UserService(){ System.out.println("this is chushihua"); } public String getName() { return name; } public void setName(String name) { this.name = name; } public void init(){ System.out.println("init------------"); } public void cleanup(){ System.out.println("cleanup------------"); } }
3.HelloWorld.java
package com.sun.service; import org.springframework.context.ApplicationContext; import org.springframework.context.support.AbstractApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class HelloWorld { public static void main(String[] args) { // TODO Auto-generated method stub AbstractApplicationContext app = new ClassPathXmlApplicationContext("service.xml"); UserService us = (UserService) app.getBean("userservice"); us.setName("Hello World"); System.out.println(us.getName()); //us.setName("sunzhiyan"); /*System.out.println(us.getName()); for(int i = 0;i < us.getArr().size();i++){ System.out.println(us.getArr().get(i)); } app.registerShutdownHook();*/ } }
这样能够进行输出。
