Maven提示程序包javax.servlet不存在

報錯

 

 但是其實javax.servlet存在，且能正常運行，但是提示這個信息也特別讓人難受。

解決方法

在pom.xml文件中添加

<dependencies>
    <dependency>
        <groupId>org.apache.geronimo.specs</groupId>
        <artifactId>geronimo-servlet_2.4_spec</artifactId>
        <version>1.1.1</version>
        <scope>provided</scope>
    </dependency>
</dependencies>
