grails 中实现数据库的可配置（二）

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 = ""
}
