RPC调用不起作用。 GUICE + DISPATCH

Question

我有一个简单的动作和结果类。处理程序只是在操作中增加变量并将结果返回。 行动

public class IncrementCounter implements Action<IncrementCounterResult> { 
    private int amount; 

    /** For serialization only. */ 
    public IncrementCounter(){} 

    public IncrementCounter(int amount){ 
     this.amount = amount; 
    } 

    public int getAmount() { 
     return amount; 
    } 
} 

结果

public class IncrementCounterResult implements Result { 
    private int amount; 
    private int current; 

    /** For serialization only. */ 
    public IncrementCounterResult(){} 

    public IncrementCounterResult(int amount, int current){ 
     this.amount = amount; 
     this.current = current; 
    } 

    public int getAmount() { 
     return amount; 
    } 

    public int getCurrent() { 
     return current; 
    } 
} 

我有一个动作模块，在这里我结合上处理行动。 ActionsModule

public class ActionsModule extends ActionHandlerModule { 
    @Override 
    protected void configureHandlers() { 
     bindHandler(IncrementCounter.class, IncrementCounterHandler.class); 
    } 
} 

DispatchServletModule

public class DispatcherServletModule extends ServletModule { 
    @Override 
    protected void configureServlets() { 
     serve("/dispatch").with(GuiceStandardDispatchServlet.class); 
    } 
} 

处理器，其增量在行动领域和结果返回。

public class IncrementCounterHandler implements ActionHandler<IncrementCounter, IncrementCounterResult> { 
    private int current = 0; 


    public Class<IncrementCounter> getActionType() { 
     return IncrementCounter.class; 
    } 


    public IncrementCounterResult execute(IncrementCounter action, ExecutionContext context) throws ActionException { 
     current += action.getAmount(); 
     return new IncrementCounterResult(action.getAmount(), current); 
    } 


    public void rollback(IncrementCounter action, IncrementCounterResult result, ExecutionContext context) throws ActionException { 
     current = result.getCurrent() - result.getAmount(); 
    } 
} 

，最后一个是听众：

public class RpcCommandGuiceConfig extends GuiceServletContextListener { 

    @Override 
    protected Injector getInjector() { 
     return Guice.createInjector(new ServerDispatchModule(), new ActionsModule()); 
    } 
} 

这里是我的的web.xml文件

<?xml version="1.0" encoding="UTF-8"?> 
<web-app> 
    <filter> 
     <filter-name>guiceFilter</filter-name> 
     <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> 
    </filter> 
    <filter-mapping> 
     <filter-name>guiceFilter</filter-name> 
     <url-pattern>/*</url-pattern> 
    </filter-mapping> 
    <listener> 
     <listener-class>server.RpcCommandGuiceConfig</listener-class> 
    </listener> 
    <welcome-file-list> 
     <welcome-file>Module.html</welcome-file> 
    </welcome-file-list> 
</web-app> 

我打电话dispatch.execute当按钮点击。并在onFailure部分跳转。 我有这个日志：

任何人都可以帮助解决这个问题吗？

我认为你需要的模块名称的前缀serve在DispatcherServletModule。在你的情况下，它看起来像它的根，所以才模块名称：Module：

serve("/Module/dispatch").with(GuiceStandardDispatchServlet.class);
