        @GET
    @Path("/{method}")
    @Produces("text/palin")
    public String handleRequest(@PathParam("method")String request) {

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

Answer 1

1。）将@Produces（＆＃34; text / palin＆＃34;）更改为@Produces（＆＃34; text / plain＆＃34;）

2。）在@Path（＆＃34; / {method}＆＃34;）中，您使用了单词method来表示路径参数的标识符。因此，改变一些明智的名称。例如，将@Path（＆＃34; / {method}＆＃34;）更改为@Path（＆＃34; / {name}＆＃34;）以及@PathParam（＆＃34;方法＆＃34;）到@PathParam（＆＃34;名称＆＃34;）（否则可能会让你感到困惑：）

3.）尝试访问此url：/ sample_maven / rest / sample / prasad（注意：此处prasad将是path参数的值）
