Web Service之Soap请求响应内容中文编码解密
java模拟Soap请求测试Web Service接口，发现Web Service响应内容中的中文竟然是编码格式。比如：
中文：退保成功
Soap中文编码：退保成功
我仔细分析后发现，退编码实际上就是Unicode编码的Soap版，正规的Unicode编码是\u9000，Soap改成自己的格式&#x[4位内容];格式。
还有其他的比如：
换行，Soap编码：
单引号，Soap为转换为html编码：'
与号，Soap为转换为html编码：&
小于号，Soap为转换为html编码：<
等等
因此，结合以上情况。想看到直观的内容，就需要解密这些编码了。解密简单，利用正则替换实现。这里介绍下Soap中文编码的解密：
1.将退替换成\u9000。替换&#x为\u，去掉分号
2.解密Unicode编码\u9000
为了更直观看Soap响应内容，我还替换了Soap换行符编码

替换为\n换行符
