springboot項目怎麼部署到外部tomcat

spring-boot項目中，默認提供內嵌的tomcat，因此打包直接生成jar包，用Java -jar命令就能夠啓動。

可是也有必定的需求，會使用外部tomcat來部署項目。下面來看：

 

1.新建項目boot-tomcat-test

2.pom依賴：(添加spring-boot-starter-tomcat依賴，打包方式爲war)

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.2.RELEASE</version>
        <relativePath/>
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>

            <artifactId>spring-boot-starter-tomcat</artifactId>
        </dependency>
    </dependencies>
    <!-- tomcat 打war包 -->
    <packaging>war</packaging>
</project>

3.啓動App繼承SpringBootServletInitializer類，並重寫configure方法

package boottest;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;

/**
 * App類描述:
 *  繼承SpringBootServletInitializer，能夠用tomcat部署
 * @author yangzhenlong
 * @since 2017/5/3
 */
@SpringBootApplication
public class App extends SpringBootServletInitializer{

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

    public static void main(String[] args) throws Exception {
        SpringApplication.run(App.class, args);
    }
}

4.Controller：

package boottest;


import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * IndexController類描述:
 *
 * @author yangzhenlong
 * @since 2017/5/3
 */
@RestController
public class IndexController {

    @RequestMapping("/")
    public String index(){
        return "hello boot";
    }
}

5.配置項目到tomcat，而後啓動tomcat

訪問：http://localhost:8080/

ok了！
