Configure MyBatis Data Source

MyBatis allows you to configure the data source using a configuration file. Here are the steps to set up the data source:

1. Set up a connection pool using a third-party connection pool library such as Apache Commons DBCP, C3P0, or HikariCP, all of which provide implementations of the DataSource interface.
2. the source of data
3. Different settings
4. Map creators

Here is a simple example:

<!-- 数据源配置 -->
<dataSource type="com.mchange.v2.c3p0.ComboPooledDataSource">
  <property name="driverClass" value="com.mysql.jdbc.Driver"/>
  <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/mydb"/>
  <property name="user" value="root"/>
  <property name="password" value="password"/>
</dataSource>

<!-- 环境配置 -->
<environments default="development">
  <environment id="development">
    <transactionManager type="JDBC"/>
    <dataSource type="POOLED">
      <property name="driver" value="${driver}"/>
      <property name="url" value="${url}"/>
      <property name="username" value="${username}"/>
      <property name="password" value="${password}"/>
    </dataSource>
  </environment>
</environments>

<!-- 加载Mapper -->
<mappers>
  <mapper resource="com/example/mapper/MyMapper.xml"/>
  <mapper class="com.example.mapper.MyMapper"/>
</mappers>

Please note that the data source type in the above example is ComboPooledDataSource from C3P0. The data source type may vary depending on the connection pool library you choose.

In practical usage, you need to configure the data source based on the requirements of your database and connection pool library. Use the above configuration example as a reference and make modifications according to your specific situation.
