Java ResourceConfig实例不包含任何根资源类

时间:2017-07-27 14:14:36

标签: java maven jersey

我正在使用jersey来构建web服务,但每次启动服务器(tomcar v9.0)时都会出现以下错误:

  

SEVERE:ResourceConfig实例不包含任何根资源   类。

我在另一篇文章中看到了一些答案,但对我来说没有任何作用

我已经从其他堆栈溢出问题中检查过的事情:

    web.xml上的
  • com.sun.jersey.config.property.packages - 它位于文件
  • 球衣上的Param不正确 - MessageService的包是api
  • 是正确的
  • 课堂上的@Path - 在课堂上
  • 清理/重建项目 - 完成
  • 错误的文件夹位置 - 它在src文件夹中

这是我的代码:

尝试添加ResourceConfig,可能类似于:

public class MyConfiguration extends ResourceConfig {

    public MyConfiguration() {
        packages(this.getClass().getPackage().getName()); // "api" in your case.
        register(RequestContextFilter.class);
    }
}
