# 问题描述： #

eclipse创建maven 的 webapp项目，创建完就报错的  
报的是

The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

# 原因分析： #

说实话，我也不知道这算是个什么问题。但是你看着行报错  
它说**javax.servlet.http.HttpServlet**这个东西在 **Build Path** 里面找不到。

# 解决方案： #

所以解决方法就有两种了

## 第一种 ##

我感觉这种方式比较简单，直接在pom.xml中加个依赖

<dependency> 
                    <groupId>javax.servlet</groupId> 
                    <artifactId>servlet-api</artifactId> 
                    <version>2.5</version> 
                    <scope>provided</scope> 
                    </dependency>
      </dependencies>

然后保存更新，ok，问题就解决了

## 第二种 ##

这种方式必须先安装好Tomcat，且在eclipse配置好tomcat  
假设eclipse还没配置的话，你看到的情况是这样的  
右击工程->Build path->Configure Build Path

libraries->add Library->server Runtime  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5MTUwMDQ5_size_16_color_FFFFFF_t_70 2]  
如果没有配置tomcant，你看到的就是空空如也

这时候你没安装Tomcat的话先按装下Tomcat  
然后配置  
配置如下  
1.打开Eclipse，Window–>Preference  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5MTUwMDQ5_size_16_color_FFFFFF_t_70 4]  
–>Server–>Runtime Environments-》add  
这里因为我的tomcat版本是7.0.94所以我选7.0，  
next  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5MTUwMDQ5_size_16_color_FFFFFF_t_70 5]  
选一下tomcat安装目录-finish

applyandclose

这时候再右击工程->Build path->Configure Build Path  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5MTUwMDQ5_size_16_color_FFFFFF_t_70 8]  
libraries-addLibrary-serverruntime-next  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5MTUwMDQ5_size_16_color_FFFFFF_t_70 9]  
此时就可以看到你的tomcat，你加进来，最后applyandcose就可以了

问题解决，拜拜
