JPA @PostPersist 和@PreUpdate回调函数中无法注入Bean得解决方案_@postupdate use bean

@Autowired
static private TeacherService teacherService;

@Autowired
static private TestService testService;

@Autowired
public void init(TeacherService teacherService, TestService testService) {
    TeacherListener.teacherService = teacherService;
    TeacherListener.testService = testService;
}

声明static私有变量，再在方法上@AutoWired注入，最后私有变量赋值。OK,搞定
