springboot多模块报错分析（一）

1. Lombok 注解与 Jackson 序列化冲突

原因：我在SysRole实体类中使用了lombox的Data数据类型
解决：导入import java.util.Date;，日期类型使用的是该类
2.运行时候用到其他模块的资源怎么办：Spring 无法创建 SysRoleController 实例，根源是无法解析该类（通常因依赖缺失、类加载失败或注解冲突导致）

[main] ERROR org.springframework.boot.SpringApplication- Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sysRoleController': Lookup method resolution failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [com.xq.web.sys_role.controller.SysRoleController] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]
	at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.determineCandidateConstructors(AutowiredAnnotationBeanPos

解决：进入其他模块，执行命令mvn clean install，之后正常运行程序
