Maven項目 Project Clean 之後運行包錯找不到XXX.xml文件

報錯 java.io.FileNotFoundException: class path resource [spring/applicationContext_*.xml]

一、問題的原因

爲何會出現這種FIleNotFoundException呢？ 原因無非兩點：

1、路徑配置錯誤

2、編譯有問題，文件不存在

二、解決辦法：

對於第一個原因，這個我們不多說，大家自己看看Java Web classpath詳解，改好配置目錄路徑，第一個原因排除，給大家一個案例參考

至於第二個原因，編譯不成功，導致文件不存在，拿Eclipse or MyEclipse爲例， 首先去項目的編譯目錄查看資源文件和class文件是否編譯成功

如果編譯目錄的下不存在資源文件，那麼編譯不成功， 解決辦法也很簡單，選擇Eclipse 工具欄上的Project ， 選擇clean up ,並勾選下面的 Build Automatically,這樣就會自動編譯了，等編譯完成，你再看文件目錄，是否存在資源文件，存在了，則完美解決

如果還不行，那麼看看你是否是通過第三方插件或工具來進行編譯的，重新對項目進行編譯就好了

通過對比發現我是第二種原因，但用上述的方法不能解決後來想到了，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>

如果不添加上面的語句，maven在編譯的時候就會打.xml和.properties最爲後綴的文件過濾掉，所以就會報錯了
