Grails：直接从src / java使用GORM的最佳方法是什么？

Question

In my grails application I have Java classes (src/java). And I want to have access to my domain classes and use GORM features(like get(), findBy..., save(), delete() and etc.) directly from my Java classes. I know, I can do this by Spring IoC: for example, I can add grails service to my Java class:

public class SimpleJavaClass{

    //...    

    @Autowired
    private ExampleService exampleService;

    //...
}

And wireup each instance of this class by Spring:

//...

GrailsApplication grailsApplication

//...

def simpleAction(){
    def instance = new SimpleJavaClass()
    grailsApplication.mainContext.autowireCapableBeanFactory.autowireBean(instance)
}

But may be there is more appropriate way to do same?

Answer 1

Using Grails 2.0, the only current way is to package your domain classes into a binary plugin (see http://grails.org/doc/2.0.x/guide/single.html#binaryPlugins )

You then can depend on this binary plugin and because it is precompiled the Java code will see many of the GORM methods which are wired into the byte code
