spring rest restful

1.只需引入jackson-mapper-asl（org.codehaus.jackson）包后，在controller中增加此方法，即可实现rest:

import im.gsj.about.vo.RestVo;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class RestConstroller {
 
 @RequestMapping(value="/RestConstroller/rest.do", method=RequestMethod.GET)
 public @ResponseBody RestVo aboutUs(){
  RestVo restVo=  new RestVo();
  restVo.setId("id");
  restVo.setName("myname");
  
  return restVo;
 }
}
