关于jar包运行报错：Exception in thread “main“ java.lang.UnsupportedClassVersionError的解决办法

打包jar包后 ，在jar路径下cmd使用命令 java -jar  jar包名字

报错：

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/TH/EdupublicAccountApplication has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

解决方法：

在Springboot项目中的pom.xml文件中更改Maven的插件配置，更改如下

<plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.5.7</version>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.7</version>
                <dependencies>
                    <dependency>
                        <groupId>org.apache.maven.shared</groupId>
                        <artifactId>maven-filtering</artifactId>
                        <version>1.3</version>
                    </dependency>
                </dependencies>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <!--<source>11</source>
                    <target>11</target>-->
<!--                    jar包运行错误后更改-->
                    <source>8</source>
                    <target>8</target>
                </configuration>
            </plugin>
        </plugins>

本人在Maven插件配置如下图1时，则运行jar包时会报错

<source>11</source>
<target>11</target>

图1        jar包运行错误时Maven插件配置

当Maven插件配置改为下图2时，则运行jar包成功

<source>8</source>
<target>8</target>

本人是个菜鸟，不知道是什么原因导致的错误，经过百度等一些查询都说是JDK版本不一致

欢迎知道原因的大佬留言
