只需要一行注解，就可以配置mybadis的多数据源

mysql:
  server:
    saas:
      url: "jdbc:mysql://localhost:3306/saas?useUnicode=true&characterEncoding=utf8"
      username: root
      password: 123
      driverClassName: com.mysql.jdbc.Driver
      initialSize: 1  #初始化大小
      minIdle: 1  #空闲连接池的大小
      maxActive: 50 #最大激活数量
    saas2:
      url: "jdbc:mysql://localhost:3306/saas2?useUnicode=true&characterEncoding=utf8"
      username: root
      password: 123
      driverClassName: com.mysql.jdbc.Driver
      initialSize: 1  #初始化大小
      minIdle: 1  #空闲连接池的大小
      maxActive: 50 #最大激活数量

@MyBadisLoader({"saas = com.llc.admin.web.dao.saas = classpath:mapper/*xml" , 
                "saas2 = com.llc.admin.web.dao.saas2 = classpath:mapper/*.xml,classpath:mapper/user/*.xml"})
@SpringBootApplication
public class WebApplication {

    public static void main(String[] args) {
        SpringApplication.run(WebApplication.class,args);
    }
}
