创建Mybatis工程时的一些小技巧

1.快速创建多个包套文件

2.快速创建多个包

java下可以直接创建package包

resource下不能直接创建包，所以要用分隔符/来分割

注意其命名规范和创建方式

与《快速创建多个包套文件》区分开来

3.快速生成前半部分代码

//打一半代码
sqlSessionFactory.openSession();
//alt+enter
SqlSession sqlSession = sqlSessionFactory.openSession();

 

解决问题

问题1

### Error querying database.  Cause: java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/...

问题2

问题3

### Error building SqlSession.
### The error may exist in com/SZX/Mapper/ParameterMapper.xml
### Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. The XML location is 'com/SZX/Mapper/ParameterMapper.xml'. Cause: org.apache.ibatis.builder.BuilderException: Wrong namespace.
