在本文中,将演示如何将Spring Boot WAR文件部署到Tomcat servlet容器中。 !!!!!! 打包在你springboot项目地方打开cmd 然后输入 mvn install package 对于Spring Boot WAR部署,需要执行三个步骤: 扩展SpringBootServletInitializer 根据提供标记嵌入式servlet容器。 更新包装为 War 测试工具: Spring Boot 1.4.2.RELEASE Tomcat 8.5.9 Maven 3 注意 在Spring Boot中,具有嵌入服务器解决方案的最终可执行JAR文件可能不适合所有生产环境,特别是部署团队(具有良好的服务器优化和监控技能知识,但缺乏开发经验的团队),他们希望完全控制服务器,并且不能接触代码。 1. 推展 SpringBootServletInitializer 使现有的 @SpringBootApplication 类扩展 SpringBootServletInitializer 1.1 - 经典Spring Boot JAR部署(更新此文件以支持WAR部署)。 SpringBootWebApplication.java 文件的内容如下 - import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class SpringBootWebApplication { public static void main(String[] args) throws Exception { SpringApplication.run(SpringBootWebApplication.class, args); } } Java 1.2 Spring Boot WAR 部署 SpringBootWebApplication.java 文件的内容如下 - import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; @SpringBootApplication public class SpringBootWebApplication extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(SpringBootWebApplication.class); } public static void main(String[] args) throws Exception { SpringApplication.run(SpringBootWebApplication.class, args); } } /*@SpringBootApplication public class SpringBootWebApplication { public static void main(String[] args) throws Exception { SpringApplication.run(SpringBootWebApplication.class, args); } }*/ Java 如果要为部署创建了一个额外的SpringBootWebApplication类,请确保告诉Spring Boot要从哪个主类开始启动程序: 在 pom.xml 文件中增加以下内容指定 - <properties> <start-class>com.yiibai.NewSpringBootWebApplicationForWAR</start-class> </properties> XML 2.提供标记嵌入式servlet容器 在 pom.xml 文件中增加以下内容指定 - <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!-- marked the embedded servlet container as provided --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> </dependencies> XML 3.更新包装为War 在 pom.xml 文件中增加以下内容指定 - <packaging>war</packaging> XML 完成,mvn打包并将$project/target/xxx.war复制到Tomcat发布目录进行部署。 4. 完整的Spring Boot WAR + Tomcat部署 4.1 - 以Spring Boot Thymeleaf为例,更新它并手动部署到Tomcat。 4.2 - 更新现有的SpringBootWebApplication并让它扩展SpringBootServletInitializer类。 SpringBootWebApplication.java文件的完整代码如下所示 - package com.yiibai; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; @SpringBootApplication public class SpringBootWebApplication extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(SpringBootWebApplication.class); } public static void main(String[] args) throws Exception { SpringApplication.run(SpringBootWebApplication.class, args); } } Java 4.3 - 更新打包包,并按提供的标记spring-boot-starter-tomcat。 pom.xml文件的完整代码如下所示 - <?xml version="1.0" encoding="UTF-8"?> <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/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>spring-boot-web-thymeleaf</artifactId> <packaging>war</packaging> <name>Spring Boot Web Thymeleaf Example</name> <description>Spring Boot Web Thymeleaf Example</description> <url>http://www.yiibai.com</url> <version>1.0</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.2.RELEASE</version> </parent> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!-- marked the embedded servlet container as provided --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <!-- hot swapping, disable cache for template, enable live reload --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> <!-- Optional, for bootstrap --> <dependency> <groupId>org.webjars</groupId> <artifactId>bootstrap</artifactId> <version>3.3.7</version> </dependency> </dependencies> <build> <plugins> <!-- Package as an executable jar/war --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> XML 4.4 - 这是可选的,将contextPath更新为/yiibai以方便稍后作为演示。准备好WAR部署文件。 application.properties 文件的完整内容如下所示 - welcome.message: Hello Yiibai server.contextPath=/yiibai Bash 4.5 - 获取Tomcat并部署WAR文件,执行以下命令 - F:workspspringbootspring-boot-war-tomcat>mvn clean package [INFO] Scanning for projects...
