前段时间把rabbitMq系统过了一遍,由于没有demo演练,俗话说:“光看不练假把式”,于是乎便着手代码的实战。很久没接触普通spring工程项目了,这不刚集成rabbitMq,各种奇葩问题。好了,废话不多说,上演问题:

看到这个报错信息,很明显没找到ServletContextListener这个类,于是搜索官方的maven中央仓库,复制粘贴

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
<scope>provided</scope>
</dependency>

引入pom文件中,结果还是找不到,报同样的信息,再仔细看,sb了,<scope>provided</scope>以为着在编译和测试时候用,解决jar冲突问题,于是赶紧去掉,然而我笑了,接着开始报错:

        at java.lang.Thread.run(Thread.java:748)

继续查找原因,写个main方法测试程序所使用的filter所在jar路径是否正确:

public static void main(String[] args) {
        URL url = Filter.class.getProtectionDomain().getCodeSource().getLocation();
        System.out.println("path:"+url.getPath()+"  name:"+url.getFile());

    }

控制台输出:path:/E:/apache-maven-3.5.3/maven-repository/javax/servlet/javax.servlet-api/4.0.1/javax.servlet-api-4.0.1.jar  name:/E:/apache-maven-3.5.3/maven-repository/javax/servlet/javax.servlet-api/4.0.1/javax.servlet-api-4.0.1.jar

没毛病啊,就是我上面pom文件引入的jar所在的路径。于是查阅网上各种资料,说法比较多的解决思路是:idea中项目需要在Project Structure——》Modules——》Libary 引入tomcat中的类库,如下图:

然并卵,根源问题好像不在这。web启动时候,优先加载的是tomcat目录lib下的jar包,于是顺着这个思路去tomcat目录lib下查找sevele-api.jar,终于找到问题所在了,tomcat10和tomcat7、8版本

 果断替换低版本的tomcat,问题解决。同时,这也为我们提供了另一种思路,如果发生类似问题,找不到问题时先检查下是不是tomcat下和项目pom引入版本是否有冲突。对于上面idea中项目需要在Project Structure——》Modules——》Libary 引入tomcat中的类库这种解决问题的方案的前提姿势要对,即版本是匹配的,也是可以的。
