org.apache.catalina.core.StandardContext.startInternal Context [] startup failed due to previous err

我在整合SSM中开启tomcat时出现了这个错误

解决方法：
删除乱码过滤器
就这个

    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping> 

原因研究中·······
才疏学浅，望大佬指教！–2020年5月4日

后来项目需要乱码处理，添上后不知道为什么又好了，真有意思······ --2020年5月5日

这里应该是在发布时lib文件里面的jar包有问题没导全 --2020年5月7日
