标题: 用test方法测试serviceImpl层时空指针异常
利用test方法测试，出现空指针异常，而且swagger文档显示no response from server

  2. public List<Test> queryProjectOrg(Integer userId) {
  3.         String role = projectInfoDao.queryRoleByUser(userId);
  4.         List<Test> list = new ArrayList<Test>();
  5.         if ("ALL".equals(role)){
  6.             list = projectInfoDao.findAllOrg();
  7.         }else {
  8.             list = projectInfoDao.queryOrg(userId);
  9.         }
  10.         return list;
  11.     }
复制代码
  1. List<Test> findAllOrg();
  2.     List<Test> queryOrg(@Param("userId")Integer userId);

  4.     String queryRoleByUser(@Param("userId") Integer userId);
复制代码

  2. List<Test> findAllOrg();
  3.     List<Test> queryOrg(@Param("userId")Integer userId);

  5.     String queryRoleByUser(@Param("userId") Integer userId);
  6. }
复制代码
