在log4j的-API-2.11.1.jar的Tomcat 7 +注解

Question

我从Tomcat在战争文件的启动得到这个异常：

Unable to process Jar entry [META-INF/versions/9/module-info.class] from Jar [jar:file:/C:/tomcat/apache-tomcat-7.0.61/webapps/monitormonitor/WEB-INF/lib/log4j-api-2.11.1.jar!/] for annotations
org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in
constant pool: 19
    at org.apache.tomcat.util.bcel.classfile.Constant.readConstant(Constant.java:97)

我试着log4j的切换到pom.xml中的旧版本，但失败了，但它仍然扫描的log4j-API 2.11.1.jar。我添加元数据的完整=“true”添加到雄猫web.xml中，但这并没有改变错误。

我读了计算器其他页面，但它并没有解决我的问题：

Tomcat 7 and Java 8 compatibility issue

Invalid byte tag in constant pool: 19 error message

后者似乎有一个很好的答案，但我不知道如何排除注释扫描文件，我也不知道该怎么排除文件影响的Web应用程序的功能。

附上我的pom.xml。它包括我的一些尝试在注释掉的版本来解决这个的。

我宁愿一个解决方案，我没有升级tomcat的。我的tomcat的版本是Apache的Tomcat的7.0.61。

Answer 1

降级权log4j的包似乎已经解决了这个问题：

    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <!-- changed version vs. ClassFormatException: Invalid byte tag in constant pool: 19 -->
        <!--<version>2.11.1</version>-->
        <version>2.7</version>
        <!--<scope>provided</scope>-->
    </dependency>

春天启动的应用程序仍不能正常启动，但是这是一个不同的问题。
