使用外部容器運行spring-boot項目：不使用spring-boot內置容器讓spring-boot項目運行在外部tomcat容器中

前言：本項目基于maven構建

spring-boot項目可以快速構建web利用，其內置的tomcat容器也10分方便我們的測試運行；

spring-boot項目需要部署在外部容器中的時候，spring-boot導出的war包沒法再外部容器（tomcat）中運行或運行報錯，本章就是詳細講授如何解決這個問題

1、pom.xml1覽

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven⑷.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>項目名稱自行自行定義</groupId> <artifactId>項目名稱自行定義</artifactId> <version>1.1.2-SNAPSHOT</version> <packaging>war</packaging> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.0.RELEASE</version> </parent> <dependencies>  <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> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> </dependency>  <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> </dependency>  <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-pool2</artifactId> </dependency> <dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>com.jayway.jsonpath</groupId> <artifactId>json-path</artifactId> <scope>test</scope> </dependency> </dependencies>  <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> <repositories> <repository> <id>spring-releases</id> <url>https://repo.spring.io/libs-release</url> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>spring-releases</id> <url>https://repo.spring.io/libs-release</url> </pluginRepository> </pluginRepositories> </project>

2、排除org.springframework.boot依賴中的tomcat內置容器

注意：只有排除內置容器，才能讓外部容器運行spring-boot項目

org.springframework.boot依賴中的排除項，測試時不要排除內置容器，會致使springboot沒法測試運行，導出war包時再加上該項便可

<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>

3、實現SpringBootServletInitializer接口

spring-boot入口類必須實現SpringBootServletInitializer接口的configure方法才能讓外部容器運行spring-boot項目

注意：SpringBootServletInitializer接口需要依賴 javax.servlet

package cn.eguid.Run; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; import org.springframework.context.annotation.ComponentScan; import cc.eguid.livepush.PushManager; import cc.eguid.livepush.PushManagerImpl; import cn.eguid.livePushServer.redisManager.RedisMQHandler; @SpringBootApplication // 開啟通用注解掃描 @ComponentScan public class Application extends SpringBootServletInitializer { /** * 實現SpringBootServletInitializer可讓spring-boot項目在web容器中運行 */ @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { builder.sources(this.getClass()); return super.configure(builder); } public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
