Question

我使用了@Provider注释

的自定义异常映射器

@Provider
public class DataNotFoundExceptionMapper implements ExceptionMapper<DataNotFoundException>{

    @Override
    public Response toResponse(DataNotFoundException arg0) {

        ErrorMessage errorMessage = new ErrorMessage(arg0.getMessage(), 404);
        return Response.status(Status.NOT_FOUND)
                        .entity(errorMessage)
                        .build();

    }

}

问题是尽管如此，我继续获得Tomcat服务器错误页面。这是我的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,

        <servlet-name>Jersey Web Application</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>
</web-app>

现在我已经在SO

上检查了这个问题

SO Question

这表明有两种解决方案，

using classes.add(EntityExceptionMapper.class); worked for me thanks a lot @Provider does not seems to work



 Adding the following line to the init
    jerseyServletFactory.addExceptionMapper(new MyCustomExceptionHandler());

有人可以帮助我了解我在哪里可以执行这两个步骤中的任何一个。任何帮助表示赞赏。

不在Jersey项目中调用ExceptionMapper方法
