在一個簡單的RMI程序中,我設法在兩個線程之間傳遞Context。現在我需要將設置/報告從上下文移動到AspectJ類。如何將方法移動到AspectJ類?
我的問題是:如何將背景下,如果我需要把它作爲問候(上下文)的參數
HelloIF
public interface HelloIF extends Remote {
String greeting(Context c) throws RemoteException;
}
你好
public class Hello extends UnicastRemoteObject implements HelloIF {
public Hello() throws RemoteException {
}
public String greeting(Context c) throws RemoteException {
c.report();
return "greeting";
}
}
的RMIServer
public class RMIServer {
public static void main(String[] args) throws RemoteException, MalformedURLException {
LocateRegistry.createRegistry(1099);
HelloIF hello = new Hello();
Naming.rebind("server.Hello", hello);
System.out.println("server.RMI Server is ready.");
}
}
RMIClient
public class RMIClient {
public static void main(String[] args) throws RemoteException, MalformedURLException, NotBoundException {
Context context = new Context("request1", Thread.currentThread().getName()+System.currentTimeMillis());
Registry registry = LocateRegistry.getRegistry("localhost");
HelloIF hello = (HelloIF) registry.lookup("server.Hello");
System.out.println(hello.greeting(context));
context.report();
}
}
語境
public class Context implements Serializable
{
private String requestType;
private String distributedThreadName;
public Context(String requestType, String distributedThreadName)
{
this.requestType = requestType;
this.distributedThreadName = distributedThreadName;
}
(...)
public void report() {
System.out.println("thread : "
+ Thread.currentThread().getName() + " "
+ Thread.currentThread().getId());
System.out.println("context : "
+ this.getDistributedThreadName() + " " + this.getRequestType());
}
}
最後一個空的AspectJ類
@Aspect
public class ReportingAspect {
@Before("call(void main(..))")
public void beforeReportClient(JoinPoint joinPoint) throws Throwable {
}
@After("call(void main(..))")
public void afterReportClient(JoinPoint joinPoint) throws Throwable {
}
@Before("call(String greeting(..))")
public void beforeReportGreeting(JoinPoint joinPoint) throws Throwable {
}
@After("call(String greeting(..))")
public void afterReportGreeting(JoinPoint joinPoint) throws Throwable {
}
}
如何從您好,RMIClient上下文()構造函數和C/context.report(移動)■報告方面?
好的,我明白了。我試圖爲連接到一個請求的所有線程設置相同的上下文(線程名稱)。我的問題是,這只是一個簡單的例子,我必須在龐大的系統中執行此操作。所以我的想法是在各個方面構建/管理上下文。有什麼建議我應該做什麼? – alicjasalamon 2012-08-01 07:01:55
