SpringBoot項目在eclipse獨立Tomcat中運行

1、首先SpringBoot默認是內嵌tomcat，要放到獨立的tomcat中運行，去掉內嵌tomcat；

第一種

1 2 3 4 5 6 7 8 9 10

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

第二種

1 2 3 4 5 6

<!-- 如果使用第三方tomcat請增加scope --> <dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-tomcat</artifactId>     <scope>provided</scope> </dependency>

2、在pom文件中將 packaging 改爲war，war 可以部署到tomcat的 webapps 中，隨tomcat的啓動而啓動。

      <packaging>war</packaging>

3、將項目的啓動類Application.java繼承SpringBootServletInitializer並重寫configure方法

@SpringBootApplication

public class DemoApplication extends SpringBootServletInitializer {

 

  public static void main(String[] args) {

    SpringApplication.run(DemoApplication.class, args);

  }

 

  @Override

  protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {

    return builder.sources(DemoApplication.class);

  }

}
