### 一、问题的原因 ###

为何会出现这种FIleNotFoundException呢？ 原因无非两点：

1、路径配置错误

2、编译有问题，文件不存在

### 二、解决办法： ###

对于第一个原因，这个我们不多说，大家自己看看Java Web classpath详解，改好配置目录路径，第一个原因排除，给大家一个案例参考

至于第二个原因，编译不成功，导致文件不存在，拿Eclipse or MyEclipse为例， 首先去项目的编译目录查看资源文件和class文件是否编译成功

如果编译目录的下不存在资源文件，那么编译不成功， 解决办法也很简单，选择Eclipse 工具栏上的Project ， 选择clean up ,并勾选下面的 Build Automatically,这样就会自动编译了，等编译完成，你再看文件目录，是否存在资源文件，存在了，则完美解决

如果还不行，那么看看你是否是通过第三方插件或工具来进行编译的，重新对项目进行编译就好了

通过对比发现我是第二种原因，但用上述的方法不能解决后来想到了，是下面的原因造成的，要在工程的pom中，添加如下的

<build>
    <resources>
                <resource>
                    <directory>src/main/resources</directory>
                    <includes>
                        <include>**/*.properties</include>
                        <include>**/*.xml</include>
                    </includes>
                    <filtering>false</filtering>
                </resource>
            </resources>
    </build>

如果不添加上面的语句，maven在编译的时候就会打.xml和.properties最为后缀的文件过滤掉，所以就会报错了
