　　项目开发中发现服务器上Tomcat启动失败

　　开始定位

　　第一步：打开tomcat日志catalina.log:

2017-07-25 17:02:43,799 [Catalina-startStop-1] ERROR org.apache.catalina.core.ContainerBase - A child container failed during start

　　找到关键点：java.lang.NoSuchMethodError: org.apache.tomcat.util.res.StringManager.getManager(Ljava/lang/Class;)Lorg/apache/tomcat/util/res/StringManager;
　　虽然不清楚是什么原因，不过很奇怪的是本地项目是能跑起来的。看了下测试机tomcat版本是7.0.56，本地是7.0.68，难道和这个有关？
第二步：判断是否和tomcat版本有关：
　　下载了一个7.0.56版本的tomcat，在本地运行，果不其然，也复现了该错误。然而是不是和tomcat有关呢？这个不不能确定，但是有一点是可以肯定的，测试机tomcat版本替换难度较大，而且还要所有环境版本同步，这个代价较大，因此转换思路，是否是类冲突了呢。。
　　开始百度

第三步：发现关键原因：类冲突
　　网上查找类似错误，有前辈遇到了，并且分析了原因：Springboot内嵌tomcat8，与tomcat7冲突,突然意识到这个需求引入了部门其他同事提供的Jar包，难道是那个Jar包导致的。。
　　OK,那我们验证下，先使用maven命令：mvn dependency:tree 输出下maven依赖树：
　　发现关键点：

果然，这个XXXJar包引用了org.springframework.boot:spring-boot-starter-web
试着使用网上的办法去掉spring-boot-starter-web依赖的spring-boot-starter-tomcat Jar包，没用

于是直接粗暴点：

 

<dependency>
    <groupId>com.xxx.xxx.xxx</groupId>
    <artifactId>xxx-client</artifactId>
        <version>1.0-SNAPSHOT</version>
        <exclusions>
            <exclusion>
            　　<groupId>org.apache.tomcat.embed</groupId>
                <artifactId>tomcat-embed-core</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.apache.tomcat.embed</groupId>
                <artifactId>tomcat-embed-el</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-websocket</artifactId>
        </exclusion>
    </exclusions>
</dependency>

重新打包运行，问题解决。
