JS decodeURIComponent 与 JAVA 解码

前端用 decodeURIComponent 编码字符串后，会生成类似

%7B%22mailNo%22%3A%223322826833883%22%2C%22status%22%3A%220%22%2C%22errCode%22%3A%221%22%2C%22message%22%3A%22%5Cu67e5%5Cu8be2%5Cu4e0d%5Cu5230%5Cu4fe1%5Cu606f%5Cuff0c%5Cu8bf7%5Cu6838%5Cu5bf9%5Cu5355%5Cu53f7%5Cu548c%5Cu5feb%5Cu9012%5Cu516c%5Cu53f8%5Cu662f%5Cu5426%5Cu6b63%5Cu786e%22%2C%22expSpellName%22%3A%22shentong%22%2C%22expTextName%22%3A%22%5Cu7533%5Cu901a%5Cu5feb%5Cu9012%22%2C%22tel%22%3A%2295543%5C%2F4008895543%22%2C%22data%22%3A%5B%5D%2C%22update%22%3A%221486536329%22%2C%22cache%22%3A7%2C%22ord%22%3A%22ASC%22%7D

这样的形式。
但是这样的形式用Java不好处理，网上大部分都说用

String result = java.net.URLDecoder.decode(url, "UTF-8");

但是效果不好，内容里如果包含双引号的话，双引号里的内容没有被解码出来。

最后在StackOverFlow上找到了，解决方案很简单

String result = new java.net.URI(url).getPath();

对，你没有看错，getPath()可以完美解码。
