在idea运行代码时，下面的代码一直空指针

Thread.currentThread().getContextClassLoader.getResourceAsStream(“core.properties”);

网上查解决方案，很多都是说idea需要把工程设置为Resources，查了已经是设置了。后来查到有的说是pom问题，经常摸索，果然是pom问题，是下面的pom设置影响到了。

<resources>
            <resource>
                <directory>${project.basedir}/libs</directory>
                <targetPath>BOOT-INF/lib/</targetPath>
                <includes>
                    <include>**/*.jar</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <targetPath>BOOT-INF/classes/</targetPath>
            </resource>
        </resources> 

配置文件是否能访问，可以看在target/classes文件夹中是否存在

后来修改了pom文件，再运行果然没有报空指针的问题了

<resources>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.properties</include>
            <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
    </resource>
    <resource>
        <directory>${project.basedir}/libs</directory>
        <targetPath>BOOT-INF/lib/</targetPath>
        <includes>
            <include>**/*.jar</include>
        </includes>
    </resource>
</resources>
