分布式配置中心config-client配置报错：java.lang.IllegalStateException: duplicate key: spring

标签：path dev ati context build list classpath 测试环境 post 今天练习分布式配置中心，写config-client配置文件，使用bootstrap.properties配置，运行没有问题。 bootstrap.properties： 但是我使用了bootstrap.yml配置文件，启动报错： bootstrap.yml： 报错如下： 报错信息显示无法加载配置文件，原因是重复建“spring”。 解决：yml文件在单一文件中，可用连续三个连字号（---）区分多个文件。更改bootstrap.yml： 重启，运行成功。 分布式配置中心config-client配置报错：java.lang.IllegalStateException: duplicate key: spring 标签：path dev ati context build list classpath 测试环境 post 原文地址：https://www.cnblogs.com/saule/p/11569868.htmlspring.application.name=config-client
