Mybatis学习错误之：重复加载mapper.xml

 1 @Before
 2     public void setUp() throws Exception {
 3         // 创建sqlSessionFactory
 4         // mybatis配置文件
 5         String resource = "SqlMapConfig.xml";
 6         // 得到配置文件流
 7         InputStream inputStream = Resources.getResourceAsStream(resource);
 8         // 创建会话工厂，传入mybatis的配置文件信息
 9         sqlSessionFactory = new SqlSessionFactoryBuilder()
10                 .build(inputStream);
11         
12     }
13     
14     @Test
15     public void testFindUserById() throws Exception{
16         SqlSession sqlSession = sqlSessionFactory.openSession();
17         UserMapper userMapper = sqlSession.getMapper(UserMapper.class);
18         User user = userMapper.findUserById(1);
19         System.out.println(user);
