maven-war-plugin配置

一、在pom.xml中做如下修改：

（一）、添加packaging

<packaging>war</packaging>

（二）、添加相关插件依赖

  1. <build>
  2.         <!--打包名字-->
  3.         <finalName>kunyuan</finalName>
  4.         <plugins>
  5.             <plugin>
  6.                 <groupId>org.apache.maven.plugins</groupId>
  7.                 <artifactId>maven-compiler-plugin</artifactId>
  8.                 <configuration>
  9.                     <source>1.8</source>
  10.                     <target>1.8</target>
  11.                 </configuration>
  12.             </plugin>
  13.             <plugin>
  14.                 <groupId>org.apache.maven.plugins</groupId>
  15.                 <artifactId>maven-war-plugin</artifactId>
  16.                 <version>3.2.0</version>
  17.                 <!--打war包时WEB-INF/web.xml报错要在下面添加以下配置-->
  18.                 <configuration>
  19.                     <failOnMissingWebXml>false</failOnMissingWebXml>
  20.                 </configuration>
  21.             </plugin>
  22.         </plugins>
  23.     </build>

 （三）、添加启动依赖

  1. <!-- 这个依赖让你能够在程序入口类：xxxAppAplication中直接执行main方法启动tomcat -->
  2.         <dependency>
  3.             <groupId>org.springframework.boot</groupId>
  4.             <artifactId>spring-boot-starter-tomcat</artifactId>
  5.             <!-- 但是这里一定要设置为provided -->
  6.             <scope>provided</scope>
  7.         </dependency>

（四）、排除springboot自带的tomcat

  1. <dependency>
  2.             <groupId>org.springframework.boot</groupId>
  3.             <artifactId>spring-boot-starter-web</artifactId>
  4.             <version>2.7.7</version>
  5.             <scope>runtime</scope>
  6.             <exclusions>
  7.                 <exclusion>
  8.                     <groupId>org.springframework.boot</groupId>
  9.                     <artifactId>spring-boot-starter-tomcat</artifactId>
  10.                 </exclusion>
  11.             </exclusions>
  12.         </dependency>

  142.             </dependency>
  143.             <dependency>
  144.                 <groupId>org.springframework.boot</groupId>

  146.                 <version>2.7.7</version>
  147.                 <scope>import</scope>
  148.                 <type>pom</type>
  149.             </dependency>
  150.         </dependencies>
  151.     </dependencyManagement>
  152. </project>

二、启动类修改如下：

  1. import org.springframework.boot.SpringApplication;
  2. import org.springframework.boot.autoconfigure.SpringBootApplication;
  3. import org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;
  4. import org.springframework.boot.builder.SpringApplicationBuilder;
  5. import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
  6.  
  7. @SpringBootApplication(exclude= {SecurityAutoConfiguration.class})
  8. // tomcat部署需要继承SpringBootServletInitializer
  9. public class KunyuanApplication extends SpringBootServletInitializer {
  10.  
  11.     public static void main(String[] args) {
  12.         SpringApplication.run(KunyuanApplication.class, args);
  13.         System.out.println("系统启动成功！");
  14.     }
  15.  
  16.     // tomcat部署重写该方法
  17.     @Override
  18.     protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
  19.         return builder.sources(KunyuanApplication.class);
  20.     }
  21.  
  22. }

做好以上步骤之后呢就可以在idea中按如下步骤打包成war包啦：

然后就会在我们的项目目录下生成一个target文件夹，里面就包含maven打出来的war包。

三、tomcat部署

（一）、本地搭建号tomcat环境后，把我们的war包丢进webapps下：

（二）、在tomcat的bin下点击startup.bat就可以启动我们的war包啦

（三）、启动成功后，我们就可以测试我们的接口是否能访问，这时候要注意当我们没对tomcat做什么特殊配置的时候，访问接口时需要带上我们war包名才可以访问。

127.0.0.1:8080/war包名/接口名
