@PostConstruct

@PostConstruct是一个注解，用于指定在bean初始化完成后要执行的方法。该注解通常与Spring框架中的依赖注入相关的类一起使用，比如在UserController类中，可以使用@PostConstruct注解来标记一个方法，该方法将在UserService注入完成后自动执行。被@PostConstruct修饰的方法会在服务器加载Servlet的时候运行，并且只会被服务器执行一次。这个注解可以用于一些常规化加载数据的操作，比如加载数据字典等。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
