无法将 JAX-RS 服务连接到 MVC 模板 [英] Can not connect JAX-RS service to MVC template

问题描述

我正在尝试使用 JAX-RS' (Jersey) MVC 模式.尝试访问 http://localhost:8080/myproject/foos/test 会导致错误阅读:

I'm attempting to make use of JAX-RS' (Jersey) MVC pattern. Attempts to reach http://localhost:8080/myproject/foos/test result in an error that reads:

java.io.IOException: The template name, /view, could not be resolved to a fully qualified template name

http://localhost:8080/myproject/foos 导致同样的错误.

我错过了什么?
