MyBatis配置和使用

SqlMapConfig.xml

<configuration>
  <prperties resource＝"db配置文件" />
  <typeAliases>扫包起别名，不区分大小写
    <package name＝"pojo包下"/>
  </typeAliases>
  <environments default＝"development">
    <environment id＝"development">
    <transactionManager type＝"JDBC"/>
    <dataSource type＝"POOLED">
      <property name＝"driver" value＝"${jdbc.driver}" />
      <property name＝"url" value＝${jdbc.url} />
      <property nane＝"username" value＝"${jdbc.username}" />
      <property name＝"password" value＝"${jdbc.password}" />
    </dataSource>
    </environment>
  </environments>

  <mappers>
    <mapper resource＝"xxx.xml" />
    <mapper name＝"xml所在包">
  </mappers>
</configuration>

调用mybatis的方法

InpuyStream in＝Resources.getResourceAsStream("SqlMapConfig.xml");
SqlSessionFactory sessionFactory＝new SqlSessionFactoryBuilder().build(in);
SqlSession session ＝sessionFactory.openSession();
session.commit();
session.close();
