springboot 配置文件属性设置环境变量报错:Circular placeholder reference 'xx:xx' in property definitions

springboot配置文件属性设置环境变量值
application.properties

test.testenv=${test.testenv:127.0.0.1}

报错 循环替换引用，原因：配置文件中属性名 和 获取的环境变量名 都是 test.testenv：

java.lang.IllegalArgumentException: Circular placeholder reference 'test.testenv:127.0.0.1' in property definitions

具体报错如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testController': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Circular placeholder reference 'test.testenv:127.0.0.1' in property definitions

解决：配置文件属性名和获取的环境变量名不要命名相同
