  • 分析问题
    从最后一行看问题：

    Error creating bean with name ‘syyyAccountServiceImpl’: Bean with name ‘syyyAccountServiceImpl’ has been injected into other beans [standardTaskServiceImpl] in its raw version as part of a circular reference

    说明在standardTaskServiceImpl bean中注入的syyyAccountServiceImpl，导致循环依赖了。如下：

  • 解决问题
    可能的解决方案：

    • 重构代码以消除循环依赖:

      将某些依赖改为方法注入: 如果可能，使用方法注入而不是构造函数注入，这样可以延迟依赖的解决，直到bean实际需要它为止。
      引入一个中间层: 通过引入一个新的服务或者将某些功能拆分到不同的类中，以消除循环依赖。

    • 使用@Lazy注解:

      在一个或多个依赖的bean上加上@Lazy注解，这会告诉Spring在需要时再初始化这个bean，而不是在启动时立即初始化。例如：
      在这里插入图片描述

    • 考虑使用ApplicationContext手动获取Bean:

      在需要的地方，通过ApplicationContext获取bean，这样避免了自动注入带来的循环依赖问题。
