J2EE之Eclipse配置Spring插件及Spring建立HelloWord

这里写图片描述

代码实现：
HelloWord.java:

package com.mooc.spring.beans;public class HelloWord {    private String name;    public void setName(String name) {        System.out.println("setname:"+name);        this.name = name;    }    public void hello(){        System.out.println("hello"+name);    }    public HelloWord(){        System.out.println("HelloWord's Constractor....");      }}

main.java:

package com.mooc.spring.beans;import java.io.IOException;import java.lang.annotation.Annotation;import java.util.Locale;import java.util.Map;import org.springframework.beans.BeansException;import org.springframework.beans.factory.BeanFactory;import org.springframework.beans.factory.NoSuchBeanDefinitionException;import org.springframework.beans.factory.config.AutowireCapableBeanFactory;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationEvent;import org.springframework.context.MessageSourceResolvable;import org.springframework.context.NoSuchMessageException;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.core.env.Environment;import org.springframework.core.io.Resource;public class main {    public static void main(String[] args) {        /*        //创建HelloWord的一个对象        HelloWord helloWord=new HelloWord();        //为那么赋值        helloWord.setName("atguigu");        helloWord.hello();        */        //1.创建SpringIOC的容器对象        ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");//      2.从IOC容器中获取Bean对象//      HelloWord helloWord=(HelloWord) context.getBean("helloWord");        //调用hello方法//      helloWord.hello();    }}

applicationContext.xml:

package com.mooc.spring.beans;import java.io.IOException;import java.lang.annotation.Annotation;import java.util.Locale;import java.util.Map;import org.springframework.beans.BeansException;import org.springframework.beans.factory.BeanFactory;import org.springframework.beans.factory.NoSuchBeanDefinitionException;import org.springframework.beans.factory.config.AutowireCapableBeanFactory;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationEvent;import org.springframework.context.MessageSourceResolvable;import org.springframework.context.NoSuchMessageException;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.core.env.Environment;import org.springframework.core.io.Resource;public class main {    public static void main(String[] args) {        /*        //创建HelloWord的一个对象        HelloWord helloWord=new HelloWord();        //为那么赋值        helloWord.setName("atguigu");        helloWord.hello();        */        //1.创建SpringIOC的容器对象        ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");//      2.从IOC容器中获取Bean对象//      HelloWord helloWord=(HelloWord) context.getBean("helloWord");        //调用hello方法//      helloWord.hello();    }}
