java - 如何合并 springframework.beans.factory.UnsatisfiedDependencyException 堆栈跟踪？

Question

这个堆栈跟踪很长而且令人困惑。它列出了 5 个原因:UnsatisfiedDependencyException/BeanCreationException/UnsatisfiedDependencyException/BeanCreationException/实际错误 (NoHostname)。

有什么方法可以将其减少到单一原因吗？

Answer 1

如你所知，spring 通过依赖注入(inject)来工作。日志中报告的每个异常子句彼此完全不同，但根据依赖注入(inject)规则，一个子句依赖于另一个子句。

BeanCreationException 和 UnsatisfiedDependencyException 是 java.lang.Runtime Exception 的子类。我们无法优雅地处理运行时异常。

异常通过堆栈数据结构算法起作用。最后一个条目通常是失败的原因，而其他条目则躺在实际失败的顶部。

• BeanCreationException - 由于主机无法创建“ session ”bean被发现。
• UnsatisfiedDependencyException - 由于“ session ”而导致“cassandraTemplate”bean 未创建(由于第一点)。
• BeanCreationException - 'tsMessageHistoryRepo' 由于找不到“cassandraTemplate”引用(由于第二点)。
• UnsatisfiedDependencyException - 'messageHistoryService' bean 不存在由于“cassandraTemplate”和“Session”bean 创建失败而创建(由于第一点和第二点)。
