java - org.springframework.beans.factory.BeanCreationException 和引起：java.lang.ClassNotFoundException：

Question

我遇到了 bean 错误，我的假设是 bean A 尝试注入 bean B 但 bean B 未能创建，因为找不到它的类。

Exiting with throwable: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'A' defined in URL(a path to a xml based configuration): Cannot resolve reference to bean 'B' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'B' defined in URL (same path location with bean A): BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [packagename1.packagename2.packagename3.packagename4.classNameC] for bean with name 'B' defined in URL [same path location with bean A]; nested exception is java.lang.ClassNotFoundException: packagename1.packagename2.packagename3.packagename4.classNameC

我也看到了原因错误

我尝试使用 java -cp 重新定义 classNameC 路径，但出现错误提示错误：无法找到或加载主类。我从pwd复制了绝对路径，然后把packagename1.packagename2.packagename3.packagename4.classNameC。
