导读：Consider these classes... src/java/com/example/SomeClass.java package com.example; public class SomeClass { public SomeClass(java.util.ListSomeOtherClass soc) { } } src/java/com/example/SomeOtherClass.java package com.example; public class

Consider these classes...

src/java/com/example/SomeClass.java

package
 com.example;

public
 class SomeClass {
public
 SomeClass(java.util.List<SomeOtherClass> soc) {

   }

}

src/java/com/example/SomeOtherClass.java

package
 com.example;

public
 class SomeOtherClass {
public
 SomeOtherClass(java.io.File f) {

   }

}

In the Spring Bean Builder you can wire those up using something like this...

grails-app/conf/resources.groovy

beans = {

   xmlns util:"http://www.springframework.org/schema/util"




   someotherbean(com.example.SomeOtherClass,new
 File('somefile.txt'))

   someotherbean2(com.example.SomeOtherClass,new
 File('somefile.txt'))


   util.list(id: 'mybeans'){

       ref(bean:'someotherbean')

       ref(bean:'someotherbean2')

   }

   somebean(com.example.SomeClass,ref('mybeans') )

}

It would be better if you could do something like this...

grails-app/conf/resources.groovy

beans = {

   someotherbean(com.example.SomeOtherClass,new
 File('somefile.txt'))

   somebean(com.example.SomeClass,[someotherbean,someotherbean2])
}
