? 在特殊情況下，grails應(yīng)用需要調(diào)用數(shù)據(jù)庫(kù)的存儲(chǔ)過(guò)程，這在grails的官方文檔里邊好像沒(méi)有提到過(guò)，在
james的blog里介紹如何解決這個(gè)問(wèn)題。
??? 代碼轉(zhuǎn)貼如下
java 代碼
?
- class?MainController?{??
- ??
- ??def?dataSource???
- ??
- ??def?index?=?{??
- ??????Sql?sql?=?new?Sql(dataSource)??
- ??????def?row?=?sql.execute("call?create_daily_hours(${new?Date()+1})")??
- ??}??
- }??
? 需要說(shuō)明的一些是：grails本身沒(méi)有提供訪問(wèn)存儲(chǔ)過(guò)程的便捷方法，而groovy的
GSQL提供了，因此grails可以直接拿過(guò)來(lái)用了，當(dāng)然也可以用spring的JdbcTemplate。
? 希望對(duì)grails用戶有點(diǎn)用。

My experience with
grails is getting richer the longer I use it for web application
developing. It's very nice that grails is built on top of spring
framework which we can take advantage of. I am not a spring user before
but with a help from the nice people at the grails forum I was able to
achieve what I want to do.
Calling
a stored procedure from a MySQL database or any other database is
simple. First we need a datasource which spring could provide for us. I
have the following code place in the resources.xml found in the spring
folder in your grails folder.
<bean id="dataSource" class=" org.apache.commons.dbcp.BasicDataSource ">
<property name="driverClassName">
<value>org.hsqldb.jdbcDriver</value>
</property>
<property name="url">
<value>jdbc:hsqldb:hsql://localhost</value>
</property>
<property name="username">
<value>sa</value>
</property>
<property name="password">
<value></value>
</property>
</bean>
I use connection pooling for better performance. In my controller here is how I use the datasource to call a store procedure.
class MainController {
def dataSource // using the datasource we define in the spring's resources.xml
def index = {
Sql sql = new Sql(dataSource)
def row = sql.execute("call create_daily_hours(${new Date()+1})")
}
}
That's it! Notice that I am using Groovy SQL instead of Spring JDBCTemplate. It's a lot more friendlier for a beginner.
Grails
really makes everything easy here and provides a lot of flexibility
thanks to it's nice integration with spring. From here everything is
possible.
