路徑如何註冊到資料庫中

在soul-spring-boot-starter-client-sofa這個專案中
可以發現類SoulSofaClientConfiguration
有2個Bean的方法

    @Bean
    public SofaServiceBeanPostProcessor sofaServiceBeanPostProcessor(final SofaConfig sofaConfig) {
        return new SofaServiceBeanPostProcessor(sofaConfig);
    }
    @Bean
 

    @ConfigurationProperties(prefix = "soul.sofa")
    public SofaConfig sofaConfig() {
        return new SofaConfig();
    }

sofaServiceBeanPostProcessor這個類中的要作用@SoulSofaClient註解相關的資訊.儲存.
sofaConfig獲取配置資訊.
