項目報錯This is often the result of over-eager type matching

　　今天啟動項目時報錯：org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'colorController': Unsatisfied dependency expressed through field 'jobService'; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'jobService': Bean with name 'jobService' has been injected into other beans [ProcessService,ProcessManualService] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesForType' with the 'allowEagerInit' flag turned off, for example.

首先控制台是從一個controller報出的錯

 跟蹤發現

 於是去jobService中看看

 然后到這兩個service中再看看，結果發現

構成了循環引用，去掉沒有使用的引用，問題解決！

當然，如果你的系統過於龐大，不好找哪里構成了循環引用，可以使用spring提供的bean懶加載解決：

@Autowired
@Lazy
private ClassA classA;
@Autowired
@Lazy
private ClassB classB;

不過解決循環依賴，當然最好的方法是重構你的代碼，進行解耦。
