Question

我正在使用primefaces 6.0和WebSphere 8.0，我想在我的webApp中实现GZip。经过大量研究后我才知道使用omnifaces GzipResponseFilter我可以使用Gzip压缩技术。这是我的web.xml：

<?xml version="1.0" encoding="UTF-8"?>

在您的构建路径中找不到

org.omnifaces.filter.GzipResponseFilter。检查您的构建路径并更正设置。

class java.lang.ClassNotFoundException：org.omnifaces.filter.GzipResponseFilter
