1.写一个 applicationContext.xml,  schema取自: ${spring}/docs/spring-framework-reference/htmlsingle/index.html

     
             
          
              
                   
        
         hello world
                
           
      
     

 

 

2.一个 POJO

public class GreetingService {    /* 属性 */    private String greeting;    public String getGreeting() {            return greeting;    }    public void setGreeting(String greeting) {            this.greeting = greeting;    }}

 

3.使用

// 初始化 应用 上下文

ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");

// 获取 Bean

GreetingService gService = (GreetingService) ac.getBean("greetingService");

// 使用

System.out.println(gService.getGreeting());
