有时启动项目失败，报错：无法解析的循环引用

Question

我们有时启动项目失败，当然大多数时候启动成功。失败时报错：

[AbstractApplicationContext.java] refresh : 487 -- Exception encountered during context initialization - cancelling refresh attempt 
org.springframework.beans.factory.BeanCurrentlyInCreationException: 
Error creating bean with name 'ITsysDesktopConfig': 
Requested bean is currently in creation: 
Is there an unresolvable circular reference?

我确定没有循环引用。

使用的是Spring版本4.1.1.RELEASE，我使用的是Spring XML文件，项目中没有注解

当我使用更高配置的电脑时，发生错误的可能性较小。

Answer 1

问题可能出在

@ComponentScan(basePackages = "com.my.app")

尝试改变

@ComponentScan(basePackages = "com.my.app")

到

@ComponentScan(basePackages = {"com.my.app.service", "com.my.app.config", "com.my.app"})

我认为这是 bean 加载器的 Spring 问题...
