测试 grails 属性是否是惰性的/未初始化的？
我似乎无法测试对象是否延迟初始化。我在这里做错了什么？
public void testLazy(){
User lazyUser = User.withCriteria {
like("userId", 'test')
fetchMode("preferences", FetchMode.LAZY )
}.get(0)
assertFalse( "DOM objects of user were not lazy initialized",
GrailsHibernateUtil.isInitialized(lazyUser, "preferences") )
}
I can't seem to test if an object is lazy initialized. What am I doing wrong here?
public void testLazy(){
User lazyUser = User.withCriteria {
like("userId", 'test')
fetchMode("preferences", FetchMode.LAZY )
}.get(0)
assertFalse( "DOM objects of user were not lazy initialized",
GrailsHibernateUtil.isInitialized(lazyUser, "preferences") )
}

你做得很好。
完全相同的代码片段对我有用 - 对于（子域对象）属性的集合，
isInitialized()返回false，对于字符串属性 -true.也许 FetchMode.LAZY 并不能保证 - 如果您请求一个简单类型，它无论如何都会被获取。首选项的类型是什么？You're doing all right.
Exactly same code piece worked for me - for a collection (of child domain objects) property,
isInitialized()returnedfalseand for a String property -true. MaybeFetchMode.LAZYis not a guarantee - if you're requesting a simple type, it gets fetched anyway.What is
preferences' type?
