SpringBoot+Groovy使用外部tomcat实例

Spring boot 使用默认的jar形式非常方便，照着官网的QuickStart就可以跑起来。真正做到了零配置。 因为Spring boot集成了tomcat，所以，创建一个sprint boot工程不需要另外部署至tomcat下。 但目前大多数情况是，公司已经有其它项目都在一个tomcat下运行，新建的项目自然也需要部署到该tomcat下。 下面就以Spring boot 1.5.3+Groovy 2.4.7为例（不同版本的配置还是有一点不同的），看看怎样把spring boot工程部署到外部tomcat中。

关键的几行

<packaging>war</packaging>

声明build时，打包成 war包

<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>

移除内置的tomcat

<dependency> <!-- To build an executable war use one of the profiles below --> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <scope>provided</scope> </dependency>

因为tomcat已移除，所以需要声明servlet类的依赖

Application类

Application类需要继承 SpringBootServletInitializer

package com.beekor.wxvote; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.support.SpringBootServletInitializer; /** * Hello world! * */ @SpringBootApplication public class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }

做好这两步，就可以把工程部署到外部tomcat下运行了。
