我正在尝试使用这个超级好的插件: https://github.com/robfletcher/grails-gson/blob/master/test/apps/gson-test/grails-app/controllers/grails/plugin/gson/test/AlbumController.groovy
因为默认的GRAILS JSON不会展开相关项目。
然而,当我尝试它时,它失败了。
现在,当我这样做时,它有效:
def levelJson() {
render ToolType.list(params) as JSON
}
这失败了:
def levelJson() {
render ToolType.list(params) as GSON
}
错误:
ERROR errors.GrailsExceptionResolver - UnsupportedOperationException occurred when processing request: [GET] /authtools/toolType/levelJson
Attempted to serialize java.lang.Class: org.hibernate.proxy.HibernateProxy. Forgot to register a type adapter?. Stacktrace follows:
Message: Attempted to serialize java.lang.Class: org.hibernate.proxy.HibernateProxy. Forgot to register a type adapter?
类:
class Artist {
String name
static hasMany = [albums: Album]
}
class Album {
String title
static belongsTo = Artist
}
答案 0 :(得分:0)
dmahapatro指出的解决方案是修改数据类belongsTo
之前(不工作):
class Album {
String title
static belongsTo = Artist
}
之后(工作):
class Album {
String title
static belongsTo = [artist: Artist]
}
