log4j-api-2.11.1.jar中的Tomcat 7 +批注 [英] Tomcat 7 + Annotations in log4j-api-2.11.1.jar
问题描述
我在war文件启动时从tomcat得到了这个异常:
I get this exception from tomcat upon startup of the war file:
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)
我试图在pom.xml中将log4j切换到旧版本,但是失败了,它仍然扫描log4j-api-2.11.1.jar.我将tomcats web.xml添加了metadata-complete ="true",但这并没有改变错误.
I tried to switch the log4j to an older version in the pom.xml, but failed, it still scans log4j-api-2.11.1.jar. I added metadata-complete="true" to the tomcats web.xml but this didn't change the error.
我在stackoverflow上阅读了其他页面,但没有解决我的问题:
I read other pages on stackoverflow, but it didn't resolve my problem:
后者似乎是一个很好的答案,但是我不了解如何从注释扫描中排除文件,而且我也不知道排除文件如何影响Web应用程序的功能.
The latter seems to have a good answer, but I don't understand how to exclude files from annotation scanning, and I also do not know how excluding files affects the functionality of the web application.
请附上我的pom.xml.它包括我为解决此问题而进行的一些尝试.
Please find attached my pom.xml. It includes some of my attempts to fix this in a commented out version.

我更喜欢不需要升级tomcat的解决方案.我的tomcat版本是apache-tomcat-7.0.61.
I would prefer a solution where I don't have to upgrade the tomcat. My tomcat version is apache-tomcat-7.0.61.
推荐答案
降级正确的log4j软件包似乎已解决了该问题:
Downgrading the right log4j package seems to have solved the problem:
<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>
spring boot应用程序仍然无法正常启动,但这是另一个问题.
The spring boot app still doesn't start up properly, but that is a different issue.
