【问题描述】：
我在尝试使用 jsf 2.0 渲染.png 图像时遇到问题，因为 JPG 可以正常工作
h:graphicImage library="img" name="logo.png" --> 不行，空指针如下图
h:graphicImage library="img" name="logo.jpg --> 没问题
更新 我从 Chrome 开发人员工具控制台看到以下内容 资源解释为图像，但使用 MIME 类型 text/html 传输
不确定是否需要在 web.xml 中设置内容类型
资源结构
WebContent/resources/img/logo.png
ErrorPageWrit E An exception occurred
java.lang.NullPointerException
