今天写了一个项目，用maven打成了war包发布到tomcat 下，但是项目一直不跑。

找了许多资料，才发现要把springboot项目打包发布到tomcat下必须把springboot内置的tomcat屏蔽掉。

整理springboot打成war包如下：

首先把pom文件的打包结果由jar改成war

<groupId>com.xc</groupId>
      <artifactId>KafkaService</artifactId>
      <version>1.0.0</version>
      <packaging>war</packaging>

引入打包插件：

<build>
    		
    		<plugins>
    		
    		
    			<plugin>
    				<artifactId>maven-compiler-plugin</artifactId>
    				<executions>
    					<execution>
    						<id>default-compile</id>
    						<phase>compile</phase>
    						<goals>
    							<goal>compile</goal>
    						</goals>
    						<configuration>
    							<source>1.7</source>
    							<target>1.7</target>
    						</configuration>
    					</execution>
    					<execution>
    						<id>default-testCompile</id>
    						<phase>test-compile</phase>
    						<goals>
    							<goal>testCompile</goal>
    						</goals>
    						<configuration>
    							<source>1.7</source>
    							<target>1.7</target>
    						</configuration>
    					</execution>
    				</executions>
    				<configuration>
    					<source>1.7</source>
    					<target>1.7</target>
    				</configuration>
    			</plugin>
    			<plugin>
    				<artifactId>maven-war-plugin</artifactId>
    				<executions>
    					<execution>
    						<id>default-war</id>
    						<phase>package</phase>
    						<goals>
    							<goal>war</goal>
    						</goals>
    						<configuration>
    							<includeEmptyDirectories>true</includeEmptyDirectories>
    							<warName>kafkaServer</warName>
    							
    							<failOnMissingWebXml>false</failOnMissingWebXml>
    							<archive>
    								<manifest>
    									<mainClass>com.xc.KafkaApplication</mainClass>
    								</manifest>
    							</archive>
    						</configuration>
    					</execution>
    				</executions>
    			</plugin>
    		</plugins>
    	</build>

排除spring boot依赖中的tomcat内置容器:

<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>

启动类继承SpringBootServletInitializer

import org.springframework.boot.SpringApplication;
    
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.context.web.SpringBootServletInitializer;
    
    
    @SpringBootApplication  
    public class KafkaApplication extends SpringBootServletInitializer
    {
    	  public static void main(String[] args) throws Exception {  
    	        SpringApplication.run(KafkaApplication.class, args);  
    	    }  
    	 
    }

OK 搞定！可以打war包了
