一. 遇到问题❓ ❗️先放一张tomcat启动时报错的日志❗️ 我所用的JDK版本为：jdk8 tomcat版本为：tomcat 7.xx 从字面以后可以看到 Unable to process Jar entry xxx for annotations （无法处理注释的xx Jar包的条目） 对应的报错是**ClassFormatException **( 类格式异常) 这个异常继承了RuntimeException（运行时异常） 官方解释如下： Thrown when the BCEL att

这个问题是tomcat版本过低报的错误，由于开发的tomcat版本高于部署的tomcat版本，所以你部署的时候会遇见这个错误。 解决办法： 方法一：将当前的tomcat7升级至高版本tomcat8。 方法二：将当前的tomcat7的tomcat\conf\catalina.properties文件，节点增加log4j-api-2.10.0.jar，然后重新启动tomcat，问题解决。(其实目的就是设置tomcat扫描时忽略这个jar包) tomcat.util.scan.DefaultJarSca

从错误日志中可以看出，问题的核心是Tomcat在处理`module-info.class`文件时抛出了`Invalid byte tag in constant pool: 19`异常。这是因为Tomcat的类加载器（具体是`BCEL`库）无法正确解析Java 9+引入的模块化信息...

需要把tomcat.util.scan.DefaultJarScanner.jarsToSkip 新增相应的jar包。经查询有的说要把相关的jar 包进行降级，但是我这边降了还是会报一样的错误，经过大牛的指点，需要修改。Server下边的tomcat的catalina.properties文件进行操作，问题解决。目前在用eclipse启动老项目的时候遇到一个报错，导致tomcat 不来，报。
