SpringBoot项目如何打war包

SpringBoot web项目打成war包：

• 修改pom文件打包方式：

  <packaging>warpackaging>
  

• 移除tomcat依赖或者将tomcat依赖scope改为provide：

  
  <dependency>
  	<groupId>org.springframework.bootgroupId>
      <artifactId>spring-boot-starter-webartifactId>
      
      <exclusions>
      	<exclusion>
          	<groupId>org.springframework.bootgroupId>
              <artifactId>spring-boot-starter-tomcatartifactId>
          exclusion>
      exclusions>
  dependency>
  

  
  <dependency>
  	<groupId>org.springframework.bootgroupId>
      <artifactId>spring-boot-starter-tomcatartifactId>
      <scope>providedscope>
  dependency>
  

• 继承SpringBootServletInitializer，实现configure方法：

  • 方式一：引导类继承、实现

    @SpringBootApplication
    public class Application extends SpringBootServletInitializer {
             
        public static void main(String[] args) {
             
            SpringApplication.run(Application.class, args);
        }
        
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
             
            return bulder.source(Application.class);
        }
    }
    

  • 方式二：新增加一个类继承、实现

    public class ServletInitializer extends SpringBootServletInitializer {
             
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
             
            //此处的Application.class为带有@SpringBootApplication注解的引导类
            return bulder.source(Application.class);
        }
    }
    

• 注意事项：

  • 使用外部Tomcat部署访问的时候，application.yml / application.properties中配置的server.port / server.servlet.context-path将失效，请使用tomcat的端口、webapps下项目名进行访问；

  • 为防止应用上下文所导致的项目访问资源加载不到的问题，建议pom.xml文件中标签下添加标签：

    <build>
    	
        <fileName>war包名称fileName>
        <plugins>
        	<plugin>
            	<groupId>org.springframework.bootgroupId>
                <artifactId>spring-boot-maven-pluginartifactId>
            plugin>
        plugins>
    build>
