Spring 3.2 - 将 @EnableAsync 添加到 @Configuration 类时项目无法加载

Question

我需要异步执行我的 bean 的方法。为此，我将@Async注释添加到我的 bean 方法和@EnableAsync带@Configuration注释的类中，但从那时起，我的项目已停止加载，并出现以下错误：

当我删除@EnableAsync注释时，一切都再次完美。如果我在这里遗漏了什么，请提出建议。

Answer 1

尝试将惰性注释添加到要自动装配的对象中。它为我解决了

@Autowired
@Lazy(value=true)
MyService servObj;
