Java @PathParam出现错误

我正在使用Jersey，我有以下两种RESTful方法：

@GET
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public List<Activity> getAllActivities() {
    return activityRepository.findAllActivities();
}

在我添加第二种方法之前，一切都很顺利。但是，我的tomcat现在给出了以下错误

org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.
[[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method GET and input mime-types as defined by @Consumes and @Produces annotations

有什么线索吗？

你应该使用

@Path（“{activityId}”）

而不是

@PathParam（“{activityId}”）

文件指出

@路径参数

将URI模板参数或包含模板参数的路径段的值绑定到资源方法参数、资源类字段或资源类bean属性

@路径

标识资源类或类方法将为其请求提供服务的URI路径

因此，应该使用

@Path

来定义资源方法将服务的URI路径

org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.
[[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method GET and input mime-types as defined by @Consumes and @Produces annotations
