如果想在Spring MVC中使用BeanBuilder，你必须确保grails-spring-.jar 包含在classpath中. 还要在/WEB-INF/web.xml文件中做如下设置：<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.groovy</param-value>
</context-param>
<context-param>
<param-name>contextClass</param-name>
<paramvalue>
org.codehaus.groovy.grails.commons.spring.GrailsWebApplicationContext</param-value>
</context-param>然后在创建 /WEB-INF/applicationContext.groovy文件并配置如下:beans {
dataSource(org.apache.commons.dbcp.BasicDataSource) {
driverClassName = "org.hsqldb.jdbcDriver"
url = "jdbc:hsqldb:mem:grailsDB"
username = "sa"
password = ""
}
}
