常量池中的无效字节标记：19 错误消息

Question

此错误消息显示 Tomcat 是 8.0.30，而我使用的是 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？

已更新（我想根据建议配置不扫描注释）：

Answer 1

Tomcat 8.0 已停产，不应再使用！

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

org.apache.tomcat.util.bcel.classfile.Constant.readConstant(Constant.java:97)

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。

您的选择：

1. 忽视。
2. 升级 Tomcat。
3. 从注释扫描中排除那些罐子。 （参见官方 Tomcat FAQ → 性能 → 如何让 Tomcat 启动更快？）。

Answer 2

为了升级tomcat版本为tomcat7-maven-plugin。

 <properties>
    <tomcat7-version>7.0.93</tomcat7-version>
</properties>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
            <dependencies>
                <dependency>
                    <groupId>org.apache.tomcat.embed</groupId>
                    <artifactId>tomcat-embed-core</artifactId>
                    <version>${tomcat7-version}</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>
