在一个简单的RMI程序中,我设法在两个线程之间传递Context。现在我需要将设置/报告从上下文移动到AspectJ类。如何将方法移动到AspectJ类?
我的问题是:如何将背景下,如果我需要把它作为问候(上下文)的参数
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();
}
}
语境
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());
}
}
最后一个空的AspectJ类
@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 {
}
}
如何从您好,RMIClient上下文()构造函数和C/context.report(移动)■报告方面?
好的,我明白了。我试图为连接到一个请求的所有线程设置相同的上下文(线程名称)。我的问题是,这只是一个简单的例子,我必须在庞大的系统中执行此操作。所以我的想法是在各个方面构建/管理上下文。有什么建议我应该做什么? – alicjasalamon 2012-08-01 07:01:55
