IDEA讀取properties文件報錯：cannot be opened because it does not exist錯誤解決方法

緣由是IDEA編譯java文件只把.class文件放到target目錄下，而不會把靜態文件加入。

 

解決辦法：在pom文件中加入resources標籤

<build>    
    <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <excludes>
                    <exclude>**/*.java</exclude>
                </excludes>
            </resource>
        </resources>
</build>
