啟動類JeewxBootApplication 添加繼承SpringBootServletInitializer

重寫實現

@SpringBootApplicationpublic class JeewxBootApplication extends SpringBootServletInitializer {  public final static Logger log = LoggerFactory.getLogger(JeewxBootApplication.class);  public static void main(String[] args) {    ConfigurableApplicationContext application = SpringApplication.run(JeewxBootApplication.class, args);    Environment env = application.getEnvironment();    String ip = InetAddress.getLocalHost().getHostAddress();    String port = env.getProperty("server.port");    String path = env.getProperty("server.servlet.context-path");    log.info("/n----------------------------------------------------------/n/t" +      "Application is running! Access URLs:/n/t" +      "Local: /t/thttp://localhost:" + port + path + "http://n/t" +      "External: /thttp://" + ip + ":" + port + path + "http://n/t" +      "----------------------------------------------------------");  }  @Override  protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {    return application.sources(JeewxBootApplication.class);  }}

pom文件添加插件

<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId>  <configuration>    <failOnMissingWebXml>false</failOnMissingWebXml>  </configuration></plugin>

pom文件添加依賴

<dependency>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-starter-tomcat</artifactId>  <scope>provided</scope></dependency><dependency>  <groupId>javax.servlet</groupId>  <artifactId>javax.servlet-api</artifactId>  <version>3.0.1</version>  <scope>provided</scope></dependency>
