java伪代码实现责任链模式

数据：Request类 类属性：public String message;

接口：IRequestProcessor#processorRequest（处理请求的方法）

责任链处理角色1：ValidRequestProcessor extends Thread Implement IRequestProcessor

//类属性：
private IRequestProcessor iRequestProcessor;  BlockingQueue blockingQueue=new BlockingQueue ();  
//构造方法：public ValidRequestProcessor (IRequestProcessor iRequestProcessor){this.iRequestProcessor=iRequestProcessor}

责任链处理角色2：PrintRequestProcessor extends Thread Implement IRequestProcessor

//类属性：
private IRequestProcessor iRequestProcessor;  
BlockingQueue blockingQueue=new BlockingQueue ();  
 //构造方法：
 public PrintRequestProcessor  (IRequestProcessor iRequestProcessor){this.iRequestProcessor=iRequestProcessor}

责任链处理角色3：SaveRequestProcessor extends Thread Implement IRequestProcessor

//类属性：
private IRequestProcessor iRequestProcessor;  
BlockingQueue blockingQueue=new BlockingQueue ();   
//构造方法：
public SaveRequestProcessor (IRequestProcessor iRequestProcessor){this.iRequestProcessor=iRequestProcessor}

责任链处理角色4：FinalRequestProcessor extends Thread Implement IRequestProcessor

//类属性：
private IRequestProcessor iRequestProcessor;  
BlockingQueue blockingQueue=new BlockingQueue ();   
//构造方法：public FinalRequestProcessor (IRequestProcessor iRequestProcessor){this.iRequestProcessor=iRequestProcessor}

测试类：

Request request=new Request("你好")

//首先将请求加入到队列中，然后启动线程进行处理

ValidRequestProcessor validRequestProcessor =new ValidRequestProcessor (request);

PrintRequestProcessor  printRequestProcessor  =new PrintRequestProcessor(validRequestProcessor );

SaveRequestProcessor  saveRequestProcessor =new SaveRequestProcessor (saveRequestProcessor);

FinalRequestProcessor  finalRequestProcessor = new FinalRequestProcessor (finalRequestProcessor);



new Thread(validRequestProcessor ).start();

new Thread(printRequestProcessor  ).start();

new Thread(saveRequestProcessor ).start();

new Thread(finalRequestProcessor ).start();
