java.lang.NoSuchMethodException: org.apache.catalina.deploy.WebXml addServlet

spring boot1.4.7 基于maven,配置tomcat7.0.69遇到这个异常

原因是spring boot 1.4.7默认tomcat是tomcat8，改为tomcat7，导致版本冲突，

解决方式是：加入exclusions标签，去掉spring boot内置的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>

 

 

上面加上

 

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.7</java.version>
		<tomcat.version>7.0.69</tomcat.version>
	</properties>

 下面加上

 

<build>
		<finalName>hello</finalName>
		<plugins>
			<plugin>
				<groupId>org.apache.tomcat.maven</groupId>
				<artifactId>tomcat7-maven-plugin</artifactId>
				<version>2.0</version>
				<!--

				<executions>
