spring - JAVA - 编程开发网

* * //2. Printer print=new Printer(); print.init(ink, paper); * print.print("打印机测试"); * * //3. Printer print=new Printer(); print.setInK(ink); * print.setPaper(paper); print.print("打印机测试"); */

// 早期的方式创建资源
		
		  Resource res=new ClassPathResource("applicationContext.xml");
		  
		  BeanFactory factory=new XmlBeanFactory(res); Printer
		 printer=factory.getBean("printer",Printer.class);
		  printer.print("答应测试");

如果使用国际化标签必须在XML中配置

	
  
	
  
		
    
     
     
      mess
     //国际标签的名字，可以配写多个

applicationContext.xml

测试代码（如果在XML文件中有两个Printer.Class必须指定唯一name的Printer printer = context.getBean("printer",Printer.class) printer）

		ApplicationContext context = new ClassPathXmlApplicationContext(
				"applicationContext.xml");
		// Printer printer=context.getBean(Printer.class);
		// 两个bean在applicationContext.xml
		/**
		 * 
   
    
     
    
    
     
    
   
  
   
		 * 
    
     
    
    
     
    
  
		 */
		//Printer printer = context.getBean(Printer.class);//会报错，必须指定唯一的
		Printer printer = context.getBean("printer",Printer.class);

		printer.print("答应测试");

声明多个XML文件bean.xml

测试代码bean.xml与applicationContext.xml里面的bean-name不能为一样

ref里的bean名称与name相等，property的name为类中的名称

ApplicationContext ctx=new ClassPathXmlApplicationContext(new String[]{"bean.xml","applicationContext.xml"});
		Printer printer=ctx.getBean("printer",Printer.class);
	    Printer printer1=ctx.getBean("printer1",Printer.class);
	    printer1.print("aaa");
	    printer.print("datiny");

mess.properties

hello=welcome,{0}
now=now is\:{0}

测试代码

 //国际化  参数1配置文件key 参数2占位符参数  参数3语言环境locale
		ApplicationContext ctx=new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml","bean.xml"});
		String hello=ctx.getMessage("hello",new Object[]{"spring"},Locale.getDefault());
		System.out.println(hello);
		String hello1=ctx.getMessage("now",new Object[]{new Date()},Locale.getDefault());
		System.out.println(hello1);

事件必须在XML文件配置

EmailEvent.java

package bean;

import org.springframework.context.ApplicationEvent;

public class EmailEvent extends ApplicationEvent{

	private static final long serialVersionUID = 1L;
	
	private String address;
	private String text;
	
	
	//source事件源
	public EmailEvent(Object source) {
		super(source);
		
	}


	public String getAddress() {
		return address;
	}

	public void setAddress(String address) {
		this.address = address;
	}


	public String getText() {
		return text;
	}


	public void setText(String text) {
		this.text = text;
	}


	public EmailEvent(Object source, String address, String text) {
		super(source);
		this.address = address;
		this.text = text;
	}
    
	
}

EmailListener.java

package bean;

import org.springframework.context.ApplicationListener;
//监听器
public class EmailListener   implements ApplicationListener
  
    {

	@Override
	public void onApplicationEvent(EmailEvent arg0) {
		System.out.println(arg0.getAddress());
		System.out.println(arg0.getText());
		System.out.println(arg0.getSource());
		System.out.println(arg0.getTimestamp());
	}

}

  /*
	     * 手动抛事件
	     */
		//先绑定事件   
		ApplicationContext ctx=new ClassPathXmlApplicationCo
