1.移除嵌入式tomcat插件
<dependency>
<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>
</dependency>
2.添加servlet依赖
<!-- 打war包时加入此项， 告诉spring-boot tomcat相关jar包用外部的，不要打进去 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
3.修改plugin
<plugins>
<!-- <plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
4.继承SpringBootServletInitializer，重写configure
@SpringBootApplication
public class BallApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(BallApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
// 注意这里要指向原先用main方法执行的Application启动类
return builder.sources(BallApplication.class);
}
}
