1.首先要在服务器上安装好以下服务：tomcat+maven+jdk+jenkins

2.maven项目中要集成的插件tomcat和maven,配置pom:

<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>tomcat-maven-plugin</artifactId>
				<version>1.1</version>
				<configuration>
					<url>${tomcat.manager.url}</url>
					<username>tomcat</username>
					<password>jjyy</password>
					<path>/jjyy</path>
					<update>true</update>
				</configuration>
			</plugin>
			<!-- <plugin> <groupId>com.google.code.maven-svn-revision-number-plugin</groupId> <artifactId>svn-revision-number-maven-plugin</artifactId> 
				<version>1.13</version> <executions> <execution> <goals> <goal>revision</goal> </goals> </execution> 
				</executions> <configuration> <entries> <entry> <prefix>SVN</prefix> </entry> </entries> </configuration> 
				</plugin> -->
			<plugin>
				<groupId>org.liquibase</groupId>
				<artifactId>liquibase-maven-plugin</artifactId>
				<version>2.0.3</version>
				<configuration>
					<changeLogFile>src/main/db/changelog/changelog.xml</changeLogFile>
					<driver>${drivers}</driver>
					<url>${jjyy.url}</url>
					<username>${jjyy.user}</username>
					<password>${jjyy.password}</password>
					<promptOnNonLocalDatabase>${jjyy.promptOnNonLocalDatabase}</promptOnNonLocalDatabase>
				</configuration>
			</plugin>

3.tomcat的tomcat-users.xml配置用户：

4.jenkins的自动部署配置：

主要是Goals and options：的配置可以为：clean install tomcat:deploy ……（上面是集成了maven的liquibase命令同步更新项目的数据表）
