由于java.lang.NoSuchMethodError，Tomcat 7无法部署应用程序

Question

我有一个无法部署的Tomcat 7应用程序，导致此错误：

SEVERE: ContainerBase.addChild: start:
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/canje]]

SEVERE: Error deploying web application archive /var/lib/tomcat7/webapps/app.war

可能是由于某些版本问题？

这些是我服务器中的版本：

Server version: Apache Tomcat/7.0.52 (Ubuntu)
Server built:   Oct 10 2018 11:13:44
Server number:  7.0.52.0
OS Name:        Linux
OS Version:     3.13.0-161-generic
Architecture:   amd64
JVM Version:    1.7.0_181-b01
JVM Vendor:     Oracle Corporation

有什么帮助吗？

谢谢Jaime

如果您使用的是spring boot，嵌入式tomcat和tomcat之间的主要冲突会导致此错误。你应该从springboot中排除tomcat。

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
   </dependency>
