Google cloudendpoint和guice

Question

我在使用google Guice获取google cloudendpoint时遇到了麻烦。从endpoints库中可用的类看来，这应该是可能的，但我不清楚如何连接它，也没有看到任何文档。

Answer 1

在guice中使用endpoint的关键是获得servlet映射权。试试看

public class YourGuiceListener extends GuiceServletContextListener {
    static class ServletModule extends GuiceSystemServiceServletModule {
        @Override
        protected void configureServlets() {
            super.configureServlets();
            Set<Class<?>> serviceClasses = new HashSet<Class<?>>();
            serviceClasses.add(YourEndpointsService1.class);
            serviceClasses.add(YourEndpointsService2.class);
            this.serveGuiceSystemServiceServlet("/_ah/spi/*", serviceClasses);//endpoints servlet mapping
            ...
        }
    }

    public static class InjectionModule extends AbstractModule {
        @Override
        protected void configure() {
            bind... //optional bindings
        }
    }
}

向web.xml添加Guice侦听器和筛选器

<listener><listener-class>package.YourGuiceListener</listener-class></listener>
<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>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
</filter-mapping>
