Java 常量池中的字节标记无效：19 错误消息

Invalid byte tag in constant pool: 19 error message

提问by user697911

This error message shows that the Tomcat is 8.0.30, and I am using JDK 8. I am creating a Spring-boot project. Some suggested that JDK 8 should be used but I indeed am using JDK 8. What's the problem here?

这个错误信息显示Tomcat是8.0.30，我使用的是JDK 8。我正在创建一个Spring-boot项目。有人建议应该使用 JDK 8，但我确实在使用 JDK 8。这里有什么问题？

Tomcat 8.0 has reached End of Life and should not be used!

Tomcat 8.0 已结束生命周期，不应使用！

The replacement is Tomcat 8.5 (implementing the same specifications as Tomcat 8.0) or Tomcat 9.0 (newer versions of specifications). See "Migration Guide" at tomcat.apache.org.

替代品是 Tomcat 8.5（实现与 Tomcat 8.0 相同的规范）或 Tomcat 9.0（较新版本的规范）。请参阅 tomcat.apache.org 上的“迁移指南”。

The BCEL library here is used to parse class files when Tomcat scans for annotations. The version that you are using does not support some features in class file format of Java 8, and thus fails when trying to parse the file.

这里的BCEL库用于Tomcat扫描注解时解析类文件。您使用的版本不支持 Java 8 类文件格式的某些功能，因此在尝试解析文件时失败。

Your options:

您的选择：

1. Ignore.
2. Upgrade Tomcat.
3. Exclude those jars from annotation scanning. (See the official Tomcat FAQ → Performance → How do I make Tomcat start up faster?).

1. 忽略。
2. 升级Tomcat。
3. 从注释扫描中排除这些 jar。（请参阅官方 Tomcat FAQ → 性能 → 如何让 Tomcat 启动得更快？）。

I also got same issue. I just changed aspectjrt and aspectjweaver jar version to

我也遇到了同样的问题。我只是将 aspectjrt 和 aspectjweaver jar 版本更改为

    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>1.8.5</version>
    </dependency>

    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>1.8.5</version>
    </dependency>

Try this one might work for you also.

试试这个也可能对你有用。
