Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘commonConvertServiceImpl’: Unsatisfied dependency expressed through field ‘****Service’; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘****ServiceImpl’: Unsatisfied dependency expressed through field ‘****Service’; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘****ServiceImpl’: Unsatisfied dependency expressed through field ‘iConvertService’; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name ‘****ServiceImpl’: Bean with name ‘***ertServiceImpl’ has been injected into other beans [***ServiceImpl,***ManagerServiceImpl] 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.

如上错误，我们可以看到主要问题是循环依赖导致项目产生错误。
也就是这个iConvertService 在@Autowired修饰的下造成的循环依赖，我们可以用如下解决办法：
-
构造函数注入改为Setter方法注入：将循环依赖的类之间的构造函数注入改为Setter方法注入。这样可以打破循环依赖链条，使得Spring能够正确地解析依赖关系。
-
使用@Lazy注解延迟初始化：在循环依赖的其中一个类上使用@Lazy注解，将其标记为延迟初始化。这样Spring会在需要时才创建对象，从而避免循环依赖问题。
-
使用@DependsOn注解指定初始化顺序：使用@DependsOn注解来指定Bean的初始化顺序。通过在循环依赖的类上使用@DependsOn注解，可以明确指定它们之间的初始化顺序，从而解决循环依赖问题。
-
使用代理对象：在循环依赖的类中使用代理对象来解决循环依赖。Spring可以通过代理对象来解决循环依赖问题，从而保持依赖关系的正确性。
-
使用@Autowired注解指定特定的Bean名称：在循环依赖的类中使用@Autowired注解，并通过@Qualifier注解指定特定的Bean名称。这样可以明确指定依赖的Bean，从而解决循环依赖问题。
而我选择的办法则是：在造成循环依赖的类里边调用的iConvertService接口上加上@Lazy。
@Autowired
@Lazy
private IConvertService iConvertService;
进而解决相关问题。
