我在2个控制器中注入spring security：
class ClassName{
def springSecurityService
在我做的一些方法中：
def user = springSecurityService.getCurrentUser() as Employee
在一个控制器中，springSecurityService工作并返回当前用户，但在另一个控制器中，我得到以下异常：
groovy.lang.MissingPropertyException: No such property: springSecurityService for class: DUMMY
我可能做错了什么？
修改
控制器：
这是好的一部分：
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
}
}
这是有问题的控制器的一部分：
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：

答案 0 :(得分：90)
通常是错误消息，如
类没有这样的属性X：DUMMY
是由IntelliJ（也许还有其他IDE）中的监视表达式引起的，该监视表达式是在不存在X的上下文中计算的。因此，如果在调试代码时发生此异常，请检查您是否正在观看涉及springSecurityService的某个表达式。如果是这样，请移除此手表，错误应该消失。
