个人查询开发

controller类：

@GetMapping("find_by_token")
public JsonData findByToken(HttpServletRequest request){
//这里的getAttribute需要在拦截器中使用setAttribute才能获取到

    Integer userId = (Integer) request.getAttribute("user_id");
    if (userId == null){
        return JsonData.buildError("查询失败");
    }
    User user = userService.findByUserId(userId);

    return JsonData.buildSuccess(user);
}

拦截器：

public class LoginInterceptor implements HandlerInterceptor {

    /**
     * 进入controller之前
     * @param request
     * @param response
     * @param handler
     * @return
     * @throws Exception
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        try {
            String accessToken = request.getHeader("token");
            if (accessToken == null){
                accessToken = request.getParameter("token");
            }

            if (StringUtils.isNotBlank(accessToken)){
                Claims claims = JwtUtils.checkJWT(accessToken);
                if (claims == null){
                    sendJsonMessage(response, JsonData.buildError("登录过期，重新登录"));
                    return false;
                }

                Integer id = (Integer) claims.get("id");
                String name = (String) claims.get("name");


//setAttribute

                request.setAttribute("user_id",id);
                request.setAttribute("name",name);
                return true;
            }
        }catch (Exception e){

        }
        sendJsonMessage(response, JsonData.buildError("登录失败，请重试"));
        return false;
    }

   ...
}

impl实现类：

@Override
public User findByUserId(Integer userId) {
    User user = userMapper.findByUserId(userId);
    user.setPwd("");
    return user;
}
