has been compiled by a more recent version of the Java Runtime (class file version 61.0)

第一次使用spring boot starter项目遇到的问题，记录下

Exception in thread “main” java.lang.UnsupportedClassVersionError: org/springframework/boot/SpringApplication has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 59.0

造成原因是创建项目时选择的spring boot 的运行环境选择高了。而eclipse的编译环境低了。

上图为查看eclipse最高编译环境。

创建spring boot 时我选择的运行环境。spring boot version 3.0.4（我理解为运行环境）

JDK version和class file version(Class编译版本号)对应关系
