Question

我使用jersey api在weblogic 12c中运行了一个rest应用程序。我有一个带有注释@provider的http请求过滤器类。但是，在部署应用程序时，过滤器类未向我在ApplicationConfig类中添加的其他资源类注册。然后我无法过滤http请求。下面是我的日志和代码

这是applicationconfig类

@ApplicationPath("/api")

public class ApplicationConfig extends Application{

@Override
public Set<Class<?>> getClasses() {
    Set<Class<?>> s = new HashSet<Class<?>>();
    s.add(MainController.class);
    s.add(UserController.class);
    s.add(ReqFilter.class);
    s.add(BusinessController.class);
    s.add(ReportsController.class);
    return s;
}

@Override
public Set<Object> getSingletons() {
    MOXyJsonProvider moxyJsonProvider = new MOXyJsonProvider();

    //moxyJsonProvider.setAttributePrefix("@");
    moxyJsonProvider.setFormattedOutput(true);
    moxyJsonProvider.setIncludeRoot(false);
    moxyJsonProvider.setMarshalEmptyCollections(true);

    HashSet<Object> set = new HashSet<Object>(1);
    set.add(moxyJsonProvider);
    return set;
}
  }

请求过滤器类

@Provider
public class ReqFilter implements ContainerRequestFilter {

Logger logger = LoggerFactory.getLogger(ReqFilter.class);

@Override
public void filter(ContainerRequestContext requestContext) throws WebApplicationException {
    logger.info(requestContext.getMethod());
}


 }

日志文件显示我调用我的网址时没有写任何内容。如何注册这样一个类？

Answer 1

有两种方法。您描述的那个必须工作，但是，尝试将Filter放在类列表中。

@Override
public Set<Class<?>> getClasses() {
    Set<Class<?>> s = new HashSet<Class<?>>();
    s.add(ReqFilter.class);
    s.add(MainController.class);
    s.add(UserController.class);
    s.add(BusinessController.class);
    s.add(ReportsController.class);
    return s;
}

第二种方法是使用@Provider。但是如果你这样做，你需要延长Application课程，留空！

我部署了一个共享库weblogic-jax-rs 然后在我的weblogic.xml中引用它

<library-ref>
  <library-name>jax-rs</library-name>
  <specification-version>2.0</specification-version>
</library-ref>

并且过滤器已注册。但是这搞砸了我所有的Java EE注释，所有从EJB调用中获取数据的URL都被破坏了。

Jax-RS没有使用@provider注释注册资源
