## 7. 如何动态卸载 Spring Boot 业务应用

目前 Spring boot 不支持动态卸载。如果要动态卸载，需要注册一个卸载的事件handler，请参考 sofaboot 的代码：[SofaBizUninstallEventHandler](https://github.com/sofastack/sofa-boot/blob/master/sofa-boot-project/sofa-boot-core/runtime-sofa-boot/src/main/java/com/alipay/sofa/runtime/SofaBizUninstallEventHandler.java)。

## 8. 日志配置

- logback 框架配置日志参数

一般而言，建议业务应用使用 application.properties 配置日志参数，**不要写在 logback-spring.xml 中**。因为业务应用使用的 LoggerContext 是宿主应用的 LoggerContext（由宿主的类加载器加载），LoggerContext 只会在初始化时读取一次宿主应用的 logback-spring.xml，所以业务应用即使配置了 logback-spring.xml 也不会被读取。

- 切换至 log4j2 框架

排除项目各项依赖中的 logback 依赖，添加 log4j2依赖。

- SOFAArk 容器日志

参考 [Ark 日志说明](../sofa-ark-ark-log) 和 [配置文档](../sofa-ark-ark-config).
