spring3 mvc 接受json格式数据是转换报错.用注解方式@RequestBody 将接受的json数据自动转换为java实体对象报错,转换不了. 点击新增 按钮 报错
org.codehaus.jackson.map.JsonMappingException: Unrecognized field "user" (Class com.springmvcext.pojo.Users), not marked as ignorable.
代码如下:
@Controller
@RequestMapping("/springMvcExt")
public class UserController {
private Logger logger = org.slf4j.LoggerFactory.getLogger(UserController.class);
@RequestMapping(value="/userManage",method=RequestMethod.POST)
@ResponseBody
public Map<String, Object> add(@RequestBody Users user) {
Map<String, Object> modelMap = new HashMap<String, Object>();
logger.info(" addUser: add ");
System.out.println("Users id is : "+user.getId());
System.out.println("Users name is : "+user.getUsername());
System.out.println("Users password is :"+user.getPassword());
modelMap.put("success", true);
return modelMap;
}
}
