springboot项目打包部署在指定的tomcat容器中

1、首先需要修改项目的打包方式，将package改为war

  <packaging>war</packaging>

2、移除spring boot web中的嵌入式tomcat

      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
          <exclusions>
              <exclusion>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter-tomcat</artifactId>
              </exclusion>
          </exclusions>
      </dependency>

3、添加servlet的依赖

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

4、新建一个类SpringBootStartApplication，继承SpringBootServletInitializer，并重写方法configure

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class SpringBootStartApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }
}

5、进入pom.xml目录，执行mvn package。编译完成后target目录下会出现一个war文件。

6、将该war文件放入tomcat容器里，然后启动tomcat，即可。
