将两个数据库用于grails中的应用程序

dataSource:
    db1:
        driverClassName: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost/db1
        username: root
        password: password

dataSource:
    db2:
        driverClassName: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost/db2
        username: root
        password: password

class Db1Table {
    String name
    // 其他属性和关联关系
    static mapping = {
        datasource 'db1'
    }
}

class Db2Table {
    String name
    // 其他属性和关联关系
    static mapping = {
        datasource 'db2'
    }
}

class MyController {
    def dataSource_db1
    def dataSource_db2

    def action() {
        def db1Data = Db1Table.findAll()
        def db2Data = Db2Table.findAll()

        // 处理数据
    }
}
