the url path and my project structure screen

Answer 1

404 错误是因为找不到页面或错误的 url。您正在使用球衣休息服务，因此您需要使用控制器和方法的路径映射。您需要在类和方法之前使用@Path 注释。

您可以找到以下示例代码：

@Path("/test")  
public class Test{  

@GET  
@Path("/{text}")  
public Response getText(@PathParam("text") String text) {  
    String output = text;  
    return Response.status(200).entity(output).build();  
}  

所以如果不检查你的代码不能给出正确的答案，我只是说错误的可能原因。
