本文记录了一次在SpringBoot应用中配置Zookeeper注册中心时遇到的问题，具体表现为配置文件中的占位符无法正确解析，导致应用启动失败。通过检查发现是由于配置项的大小写不一致所引起的错误。

properties:

server.port=${random.int[10000,19999]}
regCenter.serverList=192.168.110.10:2181
regCenter.namespace=yubo-ejob-springboot

code:

@Configuration
public class RegisterCenter {

    @Bean(initMethod = "init")
    public ZookeeperRegistryCenter registryCenter(@Value("${regCenter.serverList}") final String serverList,
                                                  @Value("${regCenter.nameSpace}") final String nameSpace      //Could not resolve placeholder 'regCenter.nameSpace' in value "${regCenter.nameSpace}" ??
                                                  ){
        return new ZookeeperRegistryCenter(new ZookeeperConfiguration( serverList, nameSpace));
    }
}

报错： Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'registryCenter' defined in class path resource [com/example/demo/RegisterCenter.class]: Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'regCenter.nameSpace' in value "${regCenter.nameSpace}"

解决：

我去，居然是大小写一样。
