注入springSecurityService不起作用

Question

在以下来自控制器的代码片段中，我在尝试访问springSecurityService.currentUser时遇到空指针异常。我希望def springSecurityService自动注入服务，我缺少什么？

@Transactional(readOnly = true)
@Secured('ROLE_USER')
class TaskController {

    static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]

    def index(Integer max) {
        params.max = Math.min(max ?: 10, 100)
def springSecurityService
def user = springSecurityService.currentUser

Answer 1

将其他Spring bean注入您的控制器或服务是在类级别而不是在方法中完成的。

例如，您的代码应如下所示：

List<String> weekdays = Arrays.asList("sun", "mon", "tue");
long sunTemp = 0;
long monTemp = 0;
for(String day : weekdays){
  if(day.equals("sun"){
  sunTemp = getSunTemp();
  }else if(day.equals("mon")){
  monTemp = getMonTemp();
  // use sunTemp ex: totalTemp = sunTemp + monTemp
  }
  //...more code
}
