Spring Boot接入 apollo 后启动 dubbo 报错

某Spring Boot项目接入 apollo 后启动 dubbo 报错Caused by: java.lang.IllegalStateException: ApplicationConfig.application == null.
TLDR

apollo-client 版本>= 1.2.0。点击查看Apollo Client最新版本
在application.properties内添加配置apollo.bootstrap.eagerLoad.enabled=true。
解决步骤复盘

根据异常猜测是 dubbo 启动时未读取到 apollo 内的配置。
0x01

先Google关键字 dubbo 2.6.2 apollo, 第二条 “继承dubbo配置不生效…”.
0x02

点开第二条之后发现跟我们的问题毫无关系，但是里面提到 apollo use cases.
0x03

使用 SourceTree 下载 apollo-use-cases，并在本机跑起来，发现没问题。
0x04

对比支付系统与其中的spring-boot-dubbo-consumer项目的异同。 1. dubbo 版本一致 2. dubbo-spring-boot-starter版本差 0.0.1 3. 支付系统启动类上多@EnableJpaRepositories, @EnableCaching,@EnableSwagger2。 4. 发现支付系统启动类里上还多一个@ImportResource(value = {"classpath*:commons-dubbo-api.xml"}.
0x05

在发现的异同里，跟 dubbo 关系最大的就是第四条。给spring-boot-dubbo-consumer的添加commons-dubbo-api-balcony 依赖，然后在启动类上添加注解 @ImportResource(value = {"classpath*:commons-dubbo-api.xml"}问题复现。可以肯定这个问题是 apollo 与 dubbo 的兼容性问题。
0x06

访问 appollo issues, 以 dubbo 作为关键字搜索。结果差不多一页，⌘ + F 用浏览器的查找配置.在第三个高亮项里找到跟我一模一样的问题。 1.2.0版本已经发布，支持把Apollo配置加载提到初始化日志系统之前，可以解决此issue中提到的问题。 ，升级 apollo 到 1.2.0 问题依旧存在。
0x07

回顾该 issue, 之前提到 不过测试了一下，#1614 合并后就可以解决这个问题。，进入#1614 发现配置apollo.bootstrap.eagerLoad.enabled项,把 apollo.bootstrap.eagerLoad.enabled=true放入项目application.properties,可成功启动项目。
