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;
}
}

答案 0 :(得分:0)
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.......
