Mybatis报错:Could not find resource mybatis-conf.xml

Mybatis报错:Could not find resource mybatis-conf.xml

报错截图:

报错内容:

java.io.IOException: Could not find resource mybatis-conf.xml at org.apache.ibatis.io.Resources.getResourceAsStream(Resources.java:114) at org.apache.ibatis.io.Resources.getResourceAsStream(Resources.java:100) at org.apache.ibatis.io.Resources.getResourceAsReader(Resources.java:160) at MybatisAdvancedTest.testQueryByNo(MybatisAdvancedTest.java:23)

CSDN上jeanFlower在文章说这是IDEA默认不编译src目录下的xml文件造成的(在后面也贴出他的解决办法),而我的mybatis-config.xml文件时在resources目录下,Debug进去观看流程发现Resources.getResourceAsReader根本没有加载到这个xml配置文件.

代码示意:

// 根据学号查询一个学生 @Test public void testQueryByNo() throws IOException { String resource = "mybatis-conf.xml"; Reader reader = Resources.getResourceAsReader(resource); SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(reader); SqlSession session = sessionFactory.openSession(); //传入StudentMapper接口，返回该接口的mapper代理对象studentMapper StudentMapper studentMapper = session.getMapper(StudentMapper.class);//接口 //通过mapper代理对象studentMapper，来调用IStudentMapper接口中的方法 Student student = studentMapper.queryStudentByNo(1); System.out.println(student+"****"); session.close(); }

解决办法:

将上面的Test方法中这部分代码进行替换:

String resource = "mybatis-conf.xml"; Reader reader = Resources.getResourceAsReader(resource);

替换成:

Reader reader = Resources.getResourceAsReader("mybatis-conf.xml");

原因暂时未知,明天Debug更新

如果是xml未被idea正常编译的问题,例如IDEA开发,但是没有将mybatis-config.xml放在resources目录下,例如放在src/main/java下,那么在pom.xml末尾添加build代码,告诉idea对我们的配置文件进行编译:

解决方案二

<build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </build>

解决方案三

将配置文件移到resources目录下,rebuild我们的项目.
