Grails中的动态修改数据库配置文件

1.在conf中定义datasource.properties，如下所示

driverClass=com.mysql.jdbc.Driver
username=root
password=root
url=jdbc:mysql://localhost:3306/testdb?useUnicode=true&characterEncoding=utf8

2. 修改DataSource.groovy,如下所示

import org.springframework.core.io.ClassPathResource
import org.springframework.core.io.support.PropertiesLoaderUtils

def properties = PropertiesLoaderUtils.loadProperties(new ClassPathResource('datasource.properties'))
dataSource {
    pooled = true
    driverClassName = properties.getProperty("driverClass")
    username = properties.getProperty("username")
    password = properties.getProperty("password")
    url = properties.getProperty("url")
//    driverClassName = "org.hsqldb.jdbcDriver"
//    username = "sa"
//    password = ""
}
