grails 开发增删改查 on IntelliJ IDEA

1.安装grails

下载grails，然后配置：
GRAILS_HOME=”D:/JavaDev/grails”
path追加：%GRAILS_HOME%/bin

2.创建grails项目

3.配置数据源

打开conf/DataSource.groovy

dataSource {
    dbCreate = "update"
    url = "jdbc:mysql://192.168.58.11:3306/grailsdb?useUnicode=true&characterEncoding=UTF-8"
    driverClassName = "com.mysql.jdbc.Driver"
    username = "root"
    password = "root"
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
//    cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
}

// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:mysql://192.168.58.11:3306/grailsdb?useUnicode=true&characterEncoding=UTF-8"
        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:mysql://192.168.58.11:3306/grailsdb?useUnicode=true&characterEncoding=UTF-8"
        }
    }
    production {
        dataSource {
            dbCreate = "update"
            url = "jdbc:mysql://192.168.58.11:3306/grailsdb?useUnicode=true&characterEncoding=UTF-8"
            properties {
               maxActive = -1
               minEvictableIdleTimeMillis=1800000
               timeBetweenEvictionRunsMillis=1800000
               numTestsPerEvictionRun=3
               testOnBorrow=true
               testWhileIdle=true
               testOnReturn=false
               validationQuery="SELECT 1"
               jdbcInterceptors="ConnectionState"
            }
        }
    }
}

4.引入数据库驱动包

lib下添加mysql-connector-java-5.1.32.jar
用命令refresh-dependencies添加到依赖

5.新建Domain类。

两种方式：（1）通过命令：create-domain-class Book（2）右键-〉New-〉Domain Class
Book代码如下：

package hellograils

class Book {
    String title
    String content
    static constraints = {
    }
}

6.创建controller和views：两种方式

（1）打Book类，点击图标上面的Controller 和Views 就可以产生代码了
（2）命令grails generate-all hellograils.Book
grails会自动创建Controller（会自动生成增、删、改、查的相关方法）和View（会自动生成增、删、改、查的相关页面）

7.运行

点击像eclipse那样的小图标运行，打开地址
http://localhost:8080/hellograils/book/index
