grails - 在DataSources.groovy中扩展多个grails DataSources？

Question

您在DataSource.groovy中定义的每个环境都在环境之外扩展了文件根目录中的基本dataSource定义。

我有两个特定的配置，我需要将它们应用于许多具有特定于环境的细微更改的不同环境。确实，我需要两个“基本定义”或某种扩展现有定义的方法。

我该怎么做？

dataSource1 {
    dbCreate = "update"
    dialect = org.hibernate.dialect.Oracle10gDialect
    pooled = false
    jndiName = "java:something"
}
dataSource2 {
            pooled = true
            driverClassName = "org.hsqldb.jdbcDriver"
            username = "sa"
            password = ""
            dbCreate = "update"
            url = "jdbc:hsqldb:mem:testDb"
}

// environment specific settings
environments {
    //extend datasource1
    production{
    }
    //extend datasource2
    development{
    }
}

Answer 1

下面将为dataSource1和dataSource2分配一个Closure(注意=)，然后可以在环境块中调用它们。

dataSource1 = {
    dbCreate = "update"
    driverClassName = "org.hsqldb.jdbcDriver"
    dialect = org.hibernate.dialect.Oracle10gDialect
    pooled = false
    jndiName = "java:something"
}

dataSource2 = {
            pooled = true
            driverClassName = "org.hsqldb.jdbcDriver"
            username = "sa"
            password = ""
            dbCreate = "update"
            url = "jdbc:hsqldb:mem:testDb"
}

environments {
    production {
        dataSource {
            dataSource1.call()
        }
    }
    development {
        dataSource {
            dataSource2.call()
        }
    }
}
