原因：jar包冲突 log 相关的jar

解决办法：

org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19_log4j

排除相关的 jar

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-security</artifactId>
      <exclusions>
        <exclusion>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

如果你的不是这个jar ，你可以按照同样的方法，在pom.xml 中查看依赖，搜索相关的 log 并且排除

然后保存

希望对你有所帮助
