springboot打包成war包

pom.xml中

war

<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository -->

<plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.4.2</version> <configuration> <skipTests>true</skipTests> </configuration> </plugin> </plugins>

添加依赖，打包时检查这两个依赖是否存在，不存在的话添加一下

<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId>

<groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope>

启动类

@EnableTransactionManagement
@ServletComponentScan
@SpringBootApplication
public class SyscloudApplication extends SpringBootServletInitializer {

@Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { return builder.sources(SyscloudApplication.class); } public static void main(String[] args) { SpringApplication.run(SyscloudApplication.class, args); } 

}
然后开始打包，修改后由于没有去掉自带的tomcat，所以项目可以正常通过springboot启动

要去掉tomcat时，将pom.xml文件中的web依赖改为：

<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!-- 移除嵌入式tomcat插件 --> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions>
