java - pom.xml 文件没有配置好

标签 java spring maven spring-boot pom.xml

我在使用 pom.xml 文件时遇到一些问题。我已经尝试了在互联网上找到的所有解决方案，但没有人帮助我。如果您能帮助我，我将非常感激。下面是我的 pom.xml 文件和错误日志。

提前谢谢您!

最佳答案

您应该添加父 Artifact 。 

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.2.RELEASE</version>
</parent>

或

If you don’t use the starter parent, in your pom.xml you need (inside the element):

  <build>
  <plugins>
   <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>${spring-boot-version}</version>
   </plugin>
   <plugin>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>
  </plugins>
 </build>
