我是靠谱客的博主搞怪蛋挞，最近开发中收集的这篇文章主要介绍解决IDEA无法读取resources文件夹，觉得挺不错的，现在分享给大家，希望可以做个参考。

IDEA无法读取resources文件夹

最近在编码过程中发现在新建ClassPathXmlApplicationContext解析XML文件中，传入classpath地址可是一直在报异常FileNotFoundException

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [META-INF/dependency-lookup-context.xml]; nested exception is java.io.FileNotFoundException: class path resource [META-INF/dependency-lookup-context.xml] cannot be opened because it does not exist

跟着源码走进去发现，在类：org.springframework.beans.factory.xml.XmlBeanDefinitionReader中loadBeanDefinitions方法找出为331行报错，为encodedResource.getResource()文件无法找出，无法找到对应文件，导致报错FileNotFoundException

所以归根结底发现为文件resources文件夹无法找出

原因有两种：

1.resources文件夹未被标记，标记resources文件夹操作方式如下：

在这里插入图片描述

2.标记resources也无效，可修改pom.xml文件,在include中添加自己想要的

<build>
        <sourceDirectory>src/main/java</sourceDirectory>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.hbm.xml</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>

            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                    <include>**/*.properties</include>
                    <include>**/*.xls</include>
                    <include>**/*.xsl</include>
                    <include>**/*.xlsx</include>
                    <include>**/*.tld</include>
                    <include>**/*.png</include>
                </includes>
            </resource>
        </resources>
    </build>
