spring-boot项目需要部署在外部容器中的时候,spring-boot导出的war包无法再外部容器(tomcat)中运行或运行报错。
为了解决这个问题,需要移除springBoot自带的tomcat容器。
具体解决方法如下:
1.pom.xml中
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<!-- 排除内置容器,排除内置容器导出成war包可以让外部容器运行spring-boot项目-->
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- 增加servlet-api依赖 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
</dependency>
2.实现SpringBootServletInitializer接口
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer; public class Application extends SpringBootServletInitializer{ public static void main(String[] args) {
SpringApplication.run(Application.class);
} @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(Application.class);
}
}
