Java Dropwizard 0.8-启用CORS

有人知道如何为dropwizard 0.8启用CORS吗？我只能找到有关版本0.7的信息

显然这不管用

FilterRegistration.Dynamic filter = environment.servlets().addFilter(
                "CORS", CrossOriginFilter.class);
        // Add URL mapping
        filter.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class),
                true, "/*");
        filter.setInitParameter(CrossOriginFilter.ALLOWED_METHODS_PARAM,
                "GET,PUT,POST,DELETE,OPTIONS");
        filter.setInitParameter(CrossOriginFilter.ALLOWED_ORIGINS_PARAM, "*");
        filter.setInitParameter(
                CrossOriginFilter.ACCESS_CONTROL_ALLOW_ORIGIN_HEADER, "*");
        filter.setInitParameter("allowedHeaders",
                "Content-Type,Authorization,X-Requested-With,Content-Length,Accept,Origin");
        filter.setInitParameter("allowCredentials", "true");

上述措施应该有效。我写了一篇关于单元测试的工作要点：它是针对0.8.1和0.9.0-SNAPSHOT进行测试的。将其作为引用运行

如果您有问题，请尝试将日志级别设置为@elec建议的调试级别：

loggers:
   org.eclipse.jetty.servlets: DEBUG

当CrossOriginFilter初始化时，它应打印出以下日志条目：

DEBUG [2015-05-07 11:55:39,247] org.eclipse.jetty.servlets.CrossOriginFilter: Cross-origin filter configuration: allowedOrigins = *, allowedMethods = GET,PUT,POST,DELETE,OPTIONS, allowedHeaders = Origin, Content-Type, Accept, Authorization, preflightMaxAge = 1800, allowCredentials = true,exposedHeaders = ,chainPreflight = true

我已经为此挣扎了将近一周，我将在这里发布我的代码，对于那些感兴趣的人，基本上步骤是相同的： 1.在应用程序类中包含此项 final FilterRegistration.Dynamic filter=environment.servlets（）.addFilter（“CORSFilter”，CrossOriginFilter.class）

在当前资源上提供响应时，请明确包含您的选项

return Response.status(status)
        .entity(new MessageResponse(this.counter.incrementAndGet(), message, response))
        .header("Access-Control-Allow-Origin", origin.isPresent() ? origin.get():"*")
        .header("Access-Control-Allow-Methods", methods)
        .header("Access-Control-Allow-Headers", "Content-Type, header-task")
        .type(MediaType.APPLICATION_JSON)
        .encoding("UTF-8")
        .allow(allow)
        .build();

您是否尝试将org.eclipse.jetty.servlet的日志级别设置为调试？

return Response.status(status)
        .entity(new MessageResponse(this.counter.incrementAndGet(), message, response))
        .header("Access-Control-Allow-Origin", origin.isPresent() ? origin.get():"*")
        .header("Access-Control-Allow-Methods", methods)
        .header("Access-Control-Allow-Headers", "Content-Type, header-task")
        .type(MediaType.APPLICATION_JSON)
        .encoding("UTF-8")
        .allow(allow)
        .build();
