springboot学习笔记(十一)springboot 打成war包问题

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
