GWT和Guice的集成

在GWT中集成Guice的关键就是让Guice来负责RemoteServiceImpl对象的创建。以下是一个最简单的示例，继承自RemoteServiceServlet，重写了processCall的方法:

package com.yingxia.tonglin.server.common;

import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.SerializationException;
import com.google.gwt.user.server.rpc.RPC;
import com.google.gwt.user.server.rpc.RPCRequest;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import com.google.inject.Guice;
import com.google.inject.Injector;

@SuppressWarnings("serial")
public class GuiceRemoteServiceServlet extends RemoteServiceServlet {

    private static final Injector injector = Guice.createInjector();

    @Override
    public String processCall(String payload) throws SerializationException {
        RPCRequest rpcRequest = RPC.decodeRequest(payload);
        Class<?> serviceClass = rpcRequest.getMethod().getDeclaringClass();
        RemoteService service = (RemoteService) injector.getInstance(serviceClass);
        return RPC.invokeAndEncodeResponse(service, rpcRequest.getMethod(), rpcRequest.getParameters(), rpcRequest.getSerializationPolicy());
    }
   
}
