同学你好！

在pom文件中添加以下代码，测试一下

<build>
    <finalName>b_mvn</finalName>
    <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <port>8081</port>
                    <path>/</path>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

同学这个错和之前的一样哦，同学将以上代码的tomcat7改为tomcat8测试一下。另外同学使用的是什么工具呢，idea还是eclipse。同学也可以重新创建一个项目测试一下。祝学习愉快~

同学你好！

有用的报错信息

根据报错的信息的提示：说明同学的jsp文件的第一行有错误，同学检查一下jsp文件是否导入了java.io.ObjectInputStream这个类，如果有同学可以删除一下。
