用test方法测试serviceImpl层时空指针异常

测试积点老人

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

1. 
   
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);
   
3. 
   
4.     String queryRoleByUser(@Param("userId") Integer userId);
   

复制代码

1. 
   
2. List<Test> findAllOrg();
   
3.     List<Test> queryOrg(@Param("userId")Integer userId);
   
4. 
   
5.     String queryRoleByUser(@Param("userId") Integer userId);
   
6. }
