springBoot jar包 改为 war包 启动

一丶 新增maven 依赖，一级 build

<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>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

二丶 新增 build

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <!--如果想在没有web.xml文件的情况下构建WAR，请设置为false。-->
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>

三丶 跟目录下，新增 FlowBootstrap 类

四丶 FlowBootStap类

@ServletComponentScan
public class FlowBootstrap extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // 注意这里要指向原先用main方法执行的Application启动类
        return builder.sources(FlowApplication.class);
    }
}


五丶 FlowApplication启动类

@SpringBootApplication
@EnableTransactionManagement // 开启事务
@MapperScan("io.shulie.center.flow.core.mapper")
public class FlowApplication  {

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

}
