java - 为什么仅在生产环境中针对 Autowire 问题进行 Spring 循环引用？

Question

#All请阅读我的问题，我已经解决了这个问题

Spring 循环引用适用于 Local 、 UAT 、 DEMO 、 STGGING 环境，但不仅仅适用于生产环境。所有环境具有相同的配置

1 JDK : 1.7.0.79

Answer 1

我不久前也遇到过这个问题。 Spring 在连接依赖项的顺序上有点随机，因此在某些情况下应用程序会启动......而在生产中它会因此错误而失败。

这个问题是 Spring 直到一两年前才提倡的一种非常糟糕的做法......问题是什么？在字段上使用 setter/@Autowired 进行注入(inject)，而不是构造函数注入(inject)。我们遇到的问题是，我们正在慢慢地将配置迁移到构造函数注入(inject)，并且我们对这个问题持开放态度，因为我们混合了两者。该问题取决于首先实例化哪个 bean。我现在记不太清楚了，但我认为如果首先实例化使用构造函数注入(inject)的bean，则会出现错误，但如果首先实例化使用setter注入(inject)的bean，则会发生错误。在这种情况下，我们应该一次性完成所有工作。当一切都使用构造函数注入(inject)时，该问题可以在所有环境中复制。

解决方案很简单:依赖循环是类设计问题的症状。你必须找到这个循环是什么并切断它。这不是 Spring 的问题，而是您的应用程序中的问题。
