我有以下cxf配置文件

服务等级

@Path("/test")
public class TestService {
    protected final Logger log = LoggerFactory.getLogger(TestService.class);

    @Path("/hello")
    @Produces("text/html")
    public String hello(@RequestBody String payload) {

        return "OK";
    }
 }

现在，每当我调用此服务时，它都会转到 hello 方法，从该方法返回字符串“OK”后，它会给出以下错误

我做错了什么吗？我正在使用 apache-cxf、spring、jas-rs。如果在其他地方回答了这个问题，请告诉我。

Answer 1

您需要一个 HTTP 方法，例如 @GET:

@GET
@Path("/hello")
@Produces("text/html")
public String hello(@RequestBody String payload) {

    return "OK";
}
