这种错误是因为maven默认简单构建项目是sevlet3.0版本,web.xml不是必须的,这时候需要手动创建webapp/WEB-INF/web.xml,web.xml可以从其他项目复制一个过来改改,
或者pom.xml添加如下配置
<build> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <configuration> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin> </plugins> </pluginManagement> </build>
修改完了别忘了右键项目Mavan/update project..
