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>

af6a
<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。
