基于 Maven + Spring + SpringMVC + Mybatis + MySql + Oracle 的项目基本框架搭建完成后，启动项目时启动失败，主要异常信息：

class path resource [config/spring/] cannot be resolved to URL because it does not exist

局部截图如下：

解决办法：

无法解析当前 URL，找不到文件！

Web.xml 配置内容如下：

解析当前 Url 需要在 classpath 后加个 “ * ” 即可，如下图：

*注：前题还需要确保配置文件路径、大小写、符号等，错一个都不能找到系统配置文件的。

当然上面个问题解决了，我还遇到其他的问题，一并记录在这儿了，可以参考一下。

在项目的持久层，我使用的是 Mybatis 的 Mapper 将对象映射到数据库，实现数据的持久方案，在运行的时候，出现 “org.apache.ibatis.binding.BindingException ”  的异常，关于这个问题的话，很简单，到项目的 mapper 映射文件夹，可以看到为空，这是由于未加载映射文件导致的，在项目的 pom.xml 配置文件中加入如下图：

为了方便各位的复制我将源码贴一下，在 pom.xml 的末尾加入如下代码片段即可，具体内容如下：

	
		
			src/main/java
			
				**/*.properties
				**/*.xml
			
			false
		
		
			src/main/resources
			
				**/*.properties
				**/*.xml
			
			false
		
	

好了，关于 “ cannot be resolved to URL because it does not exist ” 就解决了，如果还有什么疑问或遇到什么问题，可以给我留言。
