SpringBoot排除⾃动配置
springboot结构SpringBoot的⾃动配置给我们开发带来了极⼤的便利，但有些时候也带来了⼀些问题。
问题场景：
该项⽬是基于Springboot + dubbo的微服务架构，框架结构web + facade + service，某个模块的facade引⽤了Spring
Security的pom⽂件为了继承其中的接⼝，导致实现该facade接⼝的service启动时报springsecurity中XXXConfiguration中
XXXMethod不到；本意为实现springsecurity中相关接⼝被web层调⽤，wen层才是真正需要继承springsecurity，故该service需要
排除springsecurity相关⾃动配置；
解决过程：
⾸先贴上报错信息：
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of method setAuthenticationConfiguration in org.fig.figuration.WebSecurityConfigurerAdapter requir Action:
Consider defining a bean of type 'org.fig.figuration.AuthenticationConfiguration' in your configuration.
根据报错信息知道springboot在配置WebSecurityConfigurerAdapter时发⽣了错误，springboot还是很⼈性化的，启动时开启
debug⽇志级别会打印所有AutoConfiguration信息， 搜索启动⽇志查WebSecurityConfigurerAdapter；

根据⽇志信息得知是ManagementWebSecurityAutoConfiguration负责加载WebSecurityConfigurerAdapter配置，在
springboot启动类加上排除即可。
