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

@ServletComponentScanpublic 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);    }

}
