Spring mvc 使用Gson 返回Json数据 中文乱码问

Spring mvc 使用Gson 返回Json数据 中文乱码问题

最近在学习java web 使用Intllij IDEA15.0.4创建一个maven管理的Spring mvc项目，我使用的是gson转化为Json返回，返回的中文显示？？？？，

代码如下：

/**

@Controller

@RequestMapping(“/hello”)

public class HelloController {

@RequestMapping(value = “/index”, method = RequestMethod.GET)

@ResponseBody()

public String index(){

return “welcome”;

}

@RequestMapping(value = “/login”,method = RequestMethod.POST,produces = “text/html;charset=UTF-8”)

@ResponseBody()

public String login(HttpServletRequest request){

String name = request.getParameter(“username”);

String password = request.getParameter(“password”);

//调用业务处理LoginCheck

UserEntity entity=LoginCheck.login(name,password);

if(entity!=null){

;return JsonUtil.toJson(entity);

}else{

return “error”;

}

}

}

网上有很多解决方法，都看着比较复杂，最后发现只要在注解的地方加一句话，就能轻松搞定

produces = “text/html;charset=UTF-8”

@ResponseBody

@RequestMapping(value="/UserApi/SelectByPrimaryKey2",method= RequestMethod.POST,produces="text/html;charset=UTF-8")

publicStringSelectByPrimaryKey2(HttpServletRequest request,HttpServletResponse response){

User user=null;

String userJson =null;

try{

Integer userId = Integer.valueOf(request.getParameter("id"));

logger.debug("========userID===="+userId);

//查询user表中所有数据

user =this.userService.selectByPrimaryKey(userId);

Gson gson =newGson();

userJson = gson.toJson(user);

/*{"id":1,"username":"倪新生","pwd":"123","registtime":"2017-11-21 15:12:48","logintime":"2017-11-21 15:12:48","updatetime":"2017-11-21 15:13:47"}*/

logger.debug("=====用户信息json=====user="+userJson);

}catch(Exception e){

e.printStackTrace();

}

returnuserJson;

}
