SpringBoot 打包成war

1.修改pom.xml文件

<packaging>war</packaging>

<properties>

        <project.build.sourceEncoding>UTF-</project.build.sourceEncoding>

        <project.reporting.outputEncoding>UTF-</project.reporting.outputEncoding>

        <java.version>1.8</java.version>
</properties>

<!--servlet依赖-->

<dependency>

       <groupId>javax.servlet</groupId>

       <artifactId>javax.servlet-api</artifactId>

       <version>3.1.</version>

       <scope>provided</scope>

</dependency>

<build>

        <!--生成war包的名称-->

        <finalName>pay-demo</finalName>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-war-plugin</artifactId>

                <version>2.6</version>

                <configuration>

                    <failOnMissingWebXml>false</failOnMissingWebXml>

                </configuration>

            </plugin>

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-compiler-plugin</artifactId>

                <version>3.1</version>

                <configuration>

                    <source>1.8</source><!--这里版本需和服务器版本保持一致-->

                    <target>1.8</target>

                </configuration>

            </plugin>

        </plugins>

</build>

2. 修改启动类

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 DemoApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {

        SpringApplication.run(DemoApplication.class, args);

    }

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application){

        return application.sources(DemoApplication.class);

    }

}

3.最后在Maven中双击package生成war包
