我在Spring中有以下配置,但Autowiring失败,因为存储库的Impl类缺少一个init方法。Spring不应该尝试通过构造函数初始化bean,而应该使用Factory...我可能错过了一些简单的配置...或者遇到了一个错误。
我正在尝试实现一个通用存储库,所有存储库都可以共享方法和特定于我的映射域类的特定方法...
这是我的错误:
Error creating bean with name 'auditRepositoryImpl' defined in file AuditRepositoryImpl.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.domain.biz.dao.impl.AuditRepositoryImpl]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.domain.biz.dao.impl.AuditRepositoryImpl.<init>()
另外,看起来我的CustomFactory没有被识别。
