MyBatis allows you to configure the data source using a configuration file. Here are the steps to set up the data source:<\/p>\n

    \n
  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.<\/li>\n
  2. the source of data<\/li>\n
  3. Different settings<\/li>\n
  4. Map creators<\/li>\n<\/ol>\n

    Here is a simple example:<\/p>\n

    <!-- \u6570\u636e\u6e90\u914d\u7f6e -->\r\n<dataSource type=\"com.mchange.v2.c3p0.ComboPooledDataSource\">\r\n  <property name=\"driverClass\" value=\"com.mysql.jdbc.Driver\"\/>\r\n  <property name=\"jdbcUrl\" value=\"jdbc:mysql:\/\/localhost:3306\/mydb\"\/>\r\n  <property name=\"user\" value=\"root\"\/>\r\n  <property name=\"password\" value=\"password\"\/>\r\n<\/dataSource>\r\n\r\n<!-- \u73af\u5883\u914d\u7f6e -->\r\n<environments default=\"development\">\r\n  <environment id=\"development\">\r\n    <transactionManager type=\"JDBC\"\/>\r\n    <dataSource type=\"POOLED\">\r\n      <property name=\"driver\" value=\"${driver}\"\/>\r\n      <property name=\"url\" value=\"${url}\"\/>\r\n      <property name=\"username\" value=\"${username}\"\/>\r\n      <property name=\"password\" value=\"${password}\"\/>\r\n    <\/dataSource>\r\n  <\/environment>\r\n<\/environments>\r\n\r\n<!-- \u52a0\u8f7dMapper -->\r\n<mappers>\r\n  <mapper resource=\"com\/example\/mapper\/MyMapper.xml\"\/>\r\n  <mapper class=\"com.example.mapper.MyMapper\"\/>\r\n<\/mappers>\r\n<\/code><\/pre>\n
    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.<\/p>\n
    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.<\/p>\n","protected":false},"excerpt":{"rendered":"
