Maven项目红色叹号+JavaWeb: 报错信息The superclass "javax.servlet.http.HttpServlet" was not found on the Java B

<pre name="code" class="html"><span style="font-size:24px;">昨天写的关于解决JavaWeb: 报错信息<strong>The superclass "javax.servlet.http.HttpServlet" was not found on the Java</strong>的方案很好的解决了这个错误,但是它没有完全的解决我的问题,Maven项目依然有一个红色叹号存在。红色叹号存在的原因是:.classpath配置文件引用了某jar包,但是lib里却不存在此jar。我所遇到的问题又是一种新的情况,jar存在lib里存在,但还是报题目中的两个错误。仔细研究发现我的<strong>javaee-api</strong>这个jar包虽然存在于本地<strong>maven</strong>库,是个错误的jar(因为是个空的,发现比较容易发现)。解决方案如下:先把项目中maven依赖的错误<strong>javaee-api.jar</strong>删除(在pom文件去掉该jar的依赖配置然后保存即可从项目的maven依赖删除此jar),然后到maven本地库把错误的删除,再到pom文件把jar的依赖给配置好保存一下就可以把正确的jar引入到项目中,问题到此就解决了。</span>
