我在 2 个这样的 Controller 中注入(inject) spring security:
class ClassName{
def springSecurityService
在某些方法中我会这样做:
def user = springSecurityService.getCurrentUser() as Employee
在一个 Controller 中 springSecurityService 工作并返回当前用户，但在另一个 Controller 中我得到这个异常:
groovy.lang.MissingPropertyException: No such property: springSecurityService for class: DUMMY
我可能会做错什么？
编辑:
Controller :
这是好事的一部分:
class EmployeeController {
def employeeService
def springSecurityService
def me() {
def emp = springSecurityService.getCurrentUser() as Employee
def toRet = [
id: emp.id,
firstName: emp.firstName,
lastName: emp.lastName,
username: emp.username,
budget: employeeService.getUserBudget(emp)
]
render toRet as JSON
}
}
这是有问题的 Controller 的一部分:
class GroupController {
def groupService
def messageSource
def springSecurityService
def list = {
def user = springSecurityService.getCurrentUser() as Employee
def groups = groupService.getUserGroups(user)
render groups.collect() {HappyHourGroup group ->
[
id: group.id,
name: group.name,
totalCost: group.totalCost,
recieveBack: group.recieveBack,
date: group.date
]
}.sort() { a,b-> a.date<=>b.date } as JSON
}
}
这是堆栈跟踪:

最佳答案
通常会出现类似的错误消息
No such property X for class: DUMMY
是由于在 IntelliJ(可能还有其他 IDE)中有一个 watch 表达式引起的，该表达式在 X 不存在的上下文中进行评估。因此，如果在您调试代码时发生此异常，请检查您是否正在观看一些涉及 springSecurityService 的表达式。如果是这样，请移除此 watch ，错误应该会消失。
关于spring - 没有这样的属性 : springSecurityService for class: DUMMY，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20734719/
