基础测试类，其他的测试类要继承这个类
```
package tk.mybatis.simple.mapper;
import java.io.IOException;
import java.io.Reader;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.BeforeClass;
/**
* 生成sqlSessionFactory实例
* 基础测试类
*/
public class BaseMapperTest {
private static SqlSessionFactory sqlSessionFactory;
@BeforeClass
public static void init(){
try {
Reader reader = Resources.getResourceAsReader("mybatis-config.xml");
sqlSessionFactory = new SqlSessionFactoryBuilder().build(reader);
reader.close();
} catch (IOException ignore) {
ignore.printStackTrace();
}
}
public SqlSession getSqlSession(){
return sqlSessionFactory.openSession();
}
}
```
