1.可以通过配置文件

这里有三个数据源
2.可以通过注解（不需要mapping.xml）
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- <properties resource="mybatis/jdbc.properties"/> --> <typeAliases> <typeAlias alias="Player" type="gamedataserver.model.Player"/> <typeAlias alias="ServerConfig" type="gamedataserver.model.ServerConfig"/> </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 name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> </dataSource> </environment> </environments> <mappers> <mapper class="gamedataserver.dao.one.PlayerMapper"/> <mapper class="gamedataserver.dao.two.ServerConfigMapper"/> </mappers> </configuration>
package gamedataserver.dao.one;
import java.util.List;
import java.util.Map;
import org.apache.ibatis.annotations.Delete;

}
