我在Spring Boot中遇到豆类问题

时间：2019-03-27 10:54:16

标签： java spring spring-boot javabeans

我对bean和自动装配有问题。 抱歉，简短说明。我不太懂英语。 Bean可能有什么问题？

我尝试在实体类中添加@Getter和@Setter之类的龙目岛注释，以支持json序列化。

错误代码：

Package structure

我期望服务器启动

3 个答案:

答案 0 :(得分：0)

我通过在主类中添加@ComponentScan（basePackages = {“”}）注释解决了我的问题。

答案 1 :(得分：-1)

您可以在应用程序的配置类中使用以下注释启用存储库：

@EnableJpaRepositories("com.petClinic.petClinic.data_operations")

假设您的存储库位于com.petClinic.petClinic.data_operations包中

答案 2 :(得分：-1)

我也遇到了相同的错误

  

“ 不符合所有BeanPostProcessor（对于   例如：不具备自动代理资格）“

通过添加@ComponentScan和在“ basePackages ”中配置的bean软件包来解决此问题。例如

@ComponentScan(basePackages = {"com.in.security", "com.in.rest","com.in.service"})
