IDEA无法创建Servlet解决方案

本文主要是介绍IDEA无法创建Servlet解决方案，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

完美解决!!!
首先,在当前项目中创建一个maven的module.
然后在maven项目中的pom.xml文件中导入jar包,代码如下:

<!--打包方式-->
    <packaging>war</packaging>
    <!-- 导入需要使用的jar包 -->
    <dependencies>
        <!-- https://mvnrepository.com/artifact/junit/junit -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>
        <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>4.0.1</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/javax.servlet.jsp/javax.servlet.jsp-api -->
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>javax.servlet.jsp-api</artifactId>
            <version>2.3.3</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/javax.servlet/jstl -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/taglibs/standard -->
        <dependency>
            <groupId>taglibs</groupId>
            <artifactId>standard</artifactId>
            <version>1.1.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.15</version>
        </dependency>
        
    </dependencies>
    <!-- 解决静态资源导出失败问题   -->
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <excludes>
                    <exclude>/*.properties</exclude>
                    <exclude>/*.xml</exclude>
                </excludes>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <excludes>
                    <exclude>/*.properties</exclude>
                    <exclude>/*.xml</exclude>
                </excludes>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

插入进去后,保存,并点击右侧maven中的
在这里插入图片描述
等待右下角进度条加载完毕后,
进入之后

将maven项目导入的jar包导入进需要的项目,这样回去新建的时候就有Servlet了!!!
