如何在jersey WriterInterceptor实现中获取@interface参数

Question

我有接口，比如

@NameBinding
@Retention(RetentionPolicy.RUNTIME)
public @interface AutoLogged {
    boolean query() default false;
}

如何在拦截器实现中获取query参数？

@Provider
@AutoLogged
public class AutoLoggedInterceptor implements WriterInterceptor {
    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void aroundWriteTo(final WriterInterceptorContext context)
            throws IOException, WebApplicationException {
        try {
            final String methodName = this.resourceInfo.getResourceMethod().getName();
            BasicAutoLoggedProducer.makeCall(methodName);
        } catch (final Exception e) {
            e.printStackTrace(System.err);
        } finally {
            context.proceed();
        }
    }
}

我在 context.getPropertyNames 中找不到它。我看到带有 getAnnotations 方法的注释 AutoLogged。如何从界面检索参数query？

Answer 1

你可以简单地做

AutoLogged annotation = resourceInfo.getResourceMethod().getAnnotation(AutoLogged.class);
if (annotation != null) {
    boolean query = annotation.query();
}

"and want to set parameter query"

不太清楚你的意思，但是如果你的意思是你想在运行时设置值，我不太确定目的也不太确定如何去做。希望你们 "get" 而不是 "set" :-)
