java maven项目获取静态文件（针对项目打包后就找不到文件报错）

文件目录如下

InputStream trustcaInputStream  = Resources.getResourceAsStream("cert/ca.jks");

此时可能还是会报错

  打开pom.xml，必须把文件加入打包，不然是找不到的

        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                    <include>**/*.p12</include>
                    <include>**/*.jks</include>
                    <include>**/*.pkcs12</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
