spring 注解错误

配置注解后运行提示

Unsupported class file major version 61

解决：在pom中修改

将<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>17</source>
    <target>17</target>
  </configuration>
</plugin>
修改为

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>8</source>
    <target>8</target>
  </configuration>
</plugin>
刷新后可以正常运行
