SpringBoot项目打包

1：在pom.xml中把jar改为war  

<groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>war</packaging>
    <name>demo</name>
    <description>Demo project for Spring Boot</description>

2.pom.xml并且添加下面一段代码

 <!--因配置外部TOMCAT 而配置 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

3:找到<build></build>中，添加下方红色代码。打war包后war包的名字

<build>
   <finalName>demo02</finalName>

<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>

</build>

此时项目可能会有个红x，按照下图。右键工程选择maven,再选择update project...，弹窗中选择本项目，最下方点击ok红叉即消失

4：重要一步：Demo02Application启动类改为，否则打包后的war包在tomcat中无法启动。

package com.my.sb;

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

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // TODO Auto-generated method stub
        return builder.sources(Application.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

5：打war包，右键工程，run as 后选择maven install 等待编译

6：编译好后，打开项目target中可以看到所打包的demo02.war包。复制。放到tomcat中既可

tomcat访问还是老规矩需要加上项目名字:
