SpringBoot系列：SpringBoot打包成war，並在tomcat下執行
阿新 • • 發佈：2019-01-02
1、實現繼承SpringBootServletInitializer類
package com.example.demo; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; public class ServletInitializer extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(DemoApplication.class); } }
package com.example.demo; import javax.servlet.Filter; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory; import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory; import org.springframework.context.annotation.Bean; import org.springframework.web.filter.CharacterEncodingFilter; @SpringBootApplication public class DemoApplication { // 用於處理編碼問題 @Bean public Filter characterEncodingFilter() { CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter(); characterEncodingFilter.setEncoding("UTF-8"); characterEncodingFilter.setForceEncoding(true); return characterEncodingFilter; } /** * mvn打包後，需要指定內嵌tomcat的服務，否則會“找不到EmbeddedServletContainerFactory”報錯 * 也可以使用jetty服務 * @return */ @Bean public EmbeddedServletContainerFactory servletContainer() { TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory(); return factory; } public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
2、將SpringBoot打包方式改成war
<packaging>war</packaging>3、在pom中將spring-boot-starter-tomcat的scope設定成provided
如果打包成war時，不會打包tomcat相關的jar
如果打包成jar時，會打包tomcat相關jar
<!-- scope=provided，當打包成war時不會將tomcat.jar打包進去；當直接eclipse執行DemoApplication時需要 一定要配置<scope>provided</scope> --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency>
4、配置maven-war-plugin外掛
注意：failOnMissingWebXml要設定成false，因為springboot是沒有web.xml，否則mvn會出錯
outputDirectory設定成tomcat下webapps目錄下，可以自動複製到webapps目錄下
<!-- war釋出打包，並war包直接輸出到tomcat下 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<!-- 設定成false，否則檢查web.xml是否存在。因為springboot是沒有web.xml的 -->
<failOnMissingWebXml>false</failOnMissingWebXml>
<warName>myweb</warName>
<archive>
<manifest>
<mainClass>${start-class}</mainClass>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
</manifest>
</archive>
<skipTests>true</skipTests>
<skip>true</skip><!-- 跳過測試 -->
<testFailureIgnore>true</testFailureIgnore>
<!-- 將war包直接輸出到tomcat下webapps目錄下 -->
<outputDirectory>${outputDirectory}</outputDirectory>
</configuration>
</plugin>5、完整配置

通過http://127.0.0.1:8080/myweb/index訪問
如果不需要contextPath， 可以將war打包到webapps下的ROOT目錄， 則http://127.0.0.1:8080/index訪問
注意：application.properties中的埠和contextPath配置不再生效了，而是使用tomcat的方式
server.port=8081
server.context-path=/mydemo
