        //String text = "successfull";
        return "Hello " + request;
    }
    }

Answer 1

1.) 将 @Produces("text/palin") 更改为 @Produces("text/plain")

2.) 在@Path("/{method}") 中，您使用了单词method 来表示路径参数的标识符。因此，将其更改为一些合理的名称。例如，将 @Path("/{method}") 更改为 @Path("/{name}")，并将 @PathParam("method") 更改为 @PathParam("name") (否则可能会让您感到困惑:)

3.) 尝试访问此 url:/sample_maven/rest/sample/prasad (注意:这里 prasad 将是路径参数的值)
