我正在访问我的服务时遇到404 Not not Exception ...我正在向GWT Guice webapp添加一个非常简单的servlet ...我正在使用RPC来实现我的servlet。
**更新(我的更改后仍然遇到同样的问题):我意识到我可能需要在ServletModule类中绑定,所以我添加了这个:
protected void configureServlets() {
bind(BCDWebImpl.class).in(Singleton.class);
serve("/a-bcd/abcd/bcdWebUtil").with(BCDWebImpl.class);
我还在我的代码中添加了一个Window.alert(GWT.getModuleBaseURL()),输出:
http://xx.xx.xx.xx:8080/a-bcd/abcd/
这是我从firebug获得的输出:

这是我的web.xml:
<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>
<servlet>
<servlet-name>BCDWebImpl</servlet-name>
<servlet-class>com.pz.abcd.server.rest.BCDWebImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>BCDWebImpl</servlet-name>
<url-pattern>/a-bcd/abcd/BCDWeb</url-pattern>
</servlet-mapping>
BCDWeb类:
@RemoteServiceRelativePath("bcdWeb")
public interface BCDWeb extends RemoteService
{
public String getName ();
}
gwt.xml:
<module rename-to='abcd'>
<servlet class="com.pz.abcd.server.rest.BCDWebImpl" path="/bcdWeb" />
BCDEntryPoint.java:
public void onModuleLoad() {
// This is required for Gwt-Platform proxy's generator
DelayedBindRegistry.bind(ginjector);
ginjector.getPlaceManager().revealCurrentPlace();
setUpEnv();
}
private void setUpEnv(){
BCDWebAsync web = GWT.create(BCDWeb.class);
ServiceDefTarget endpoint = (ServiceDefTarget)web;
endpoint.setServiceEntryPoint(GWT.getModuleBaseURL() + "bcdWeb");
web.getName(new AsyncCallback<String>() {
@Override
public void onFailure(Throwable caught) {
GWT.log(caught.getMessage());
}
@Override
public void onSuccess(final String name) {
// do something here;
}
});
}
同样,这个webapp正在使用guice,但我正在尝试添加一个非常简单的RPC servlet ...任何想法可能是什么问题?
提前致谢。
答案 0 :(得分:0)
网址格式区分大小写
你在web.xml
<url-pattern>/a-bcd/abcd/BCDWeb</url-pattern>
^____
|
@RemoteServiceRelativePath("bcdWeb"); //and using the path in small letters.
尝试将模式更改为
<url-pattern>/a-bcd/abcd/bcdWeb</url-pattern>
