第一种方式：(ResponseEnity)

使用ResponseEnity

@Controller
public class JSONController {
   @RequestMapping(value={"/{name}"}, method=RequestMethod.GET)
   public ResponseEntity<Shop> hello(@PathVariable String name) {
       Shop shop = new Shop();
       shop.setName(name);
       shop.setStaffName(new String[]{"zwh1","zwh2"});
       return new ResponseEntity<Shop>(shop,HttpStatus.OK);
   }
}

输出Json: {"name":"zzz","staffName":["zwh1","zwh2"]}

第二种方式：(@ResponseBody)

使用@ResponseBody

@Controller
public class JSONController {
   @RequestMapping(value={"/{name}"}, method=RequestMethod.GET)
   public @ResponseBody Shop hello(@PathVariable String name) {
       Shop shop = new Shop();
       shop.setName(name);
       shop.setStaffName(new String[]{"zwh1","zwh2"});
       return shop;
   }
}

 

 输出Json: {"name":"zzz","staffName":["zwh1","zwh2"]}

 

第三种方式： (MappingJacksonJsonView)

@Controller
public class JSONController {
   @RequestMapping(value={"/{name}"}, method=RequestMethod.GET)
   public ModelAndView hello(@PathVariable String name) {
       ModelAndView mv =newModelAndView(new MappingJacksonJsonView());
       Shop shop =new Shop();
       shop.setName(name);
       shop.setStaffName(newString[]{"zwh1","zwh2"});
       mv.addObject(shop);
       return mv;
   }
}

 

 输出Json:{"shop":{"name":"zzz","staffName":["zwh1","zwh2"]}}
