let ele = new DOMParser().parseFromString(str, "text/xml")
获取到document对象
然后ele.firstChild就是你想要的html元素来
String text = "字符内容"String htmlFileName = UUIDUtil.generateUUID()+".html"
String htmlPath = imgPath+ File.separatorChar+htmlFileName
File file2 = new File(htmlPath)
StringBuilder sb = new StringBuilder()
try {
file2.createNewFile()//创建文件
sb.append("<html><head><meta http-equiv=\"Content-Type\" content=\"text/htmlcharset=utf-8\"><title>Html Test</title></head><body>")
sb.append("<div>")
sb.append(text)
sb.append("</div>")
sb.append("</body></html>")
PrintStream printStream = new PrintStream(new FileOutputStream(file2))
printStream.println(sb.toString())//将字符串写入文件
} catch (IOException e) {
code = 0
e.printStackTrace()
