Question

我是Resteasy和Guice的新手，但是我在使用这个简单的教程时遇到了问题。这是我的相关文件。我已经复制了下面的错误，但我没有看到任何人和我有同样的问题。我已经让Resteasy在没有Guice的情况下工作了，之后在pom中为resteasy-jaxrs添加了提供的标签，但这似乎与resteasy-guice没有关系。我希望有人能指出我正确的方向。

由于

MyModule.java

package foo.guice;

import com.google.inject.Module;
import com.google.inject.Binder;
import foo.rest.Controller;

public class MyModule implements Module {
    @Override
    public void configure(final Binder binder) {
        binder.bind(Controller.class);
    }
}

Controller.java

package foo.rest;
import javax.ws.rs.*;
import javax.ws.rs.core.Response;
import com.google.inject.Inject;

@Path("hello")
public class Controller
{
   @GET
   @Path("{name}")
   public String hello(@PathParam("name") final String name) {
      return "Hello " + name;
   }
}

Answer 1

显然对我来说，一旦我把重新回到2.3.2.Final，这一切都奏效了，所以是的.......
