被坑记之：从拼接字符串中将对象解析出来

描述下背景：目前做一个项目，需要对接第三方提供的WebService接口，读取xml数据并保存进数据库。然后而拿到数据的时候有点蒙蔽。返回来的数据是这样子的：

[{material_number=04.04.09.001.0398, material_model=WYD33W04-2200, qty=128, entry_id=frpbjbgpQheLY3CkGASZEiYEHMU=, material_name=浴霸2200W, totalReceiptQty=0},

好吧

1、直接序列化对象肯定是不可行的了

2、尝试将字符串通过字符替换的方式转换为可序列化的Json格式，最终也以失败告终，因为它的值包含了“，”、“：”等，即什么情况都可以出现，无法进行替换。

3、好吧 那只能进行字符截取了：将类的属性名称解析出来，遍历获得属性名称在字符串中的索引，再通过索引将字符串中的值分割出来。

4、好吧 不知道有没有更好的办法

5、花了一个晚上的时候来处理了这个问题

6、最坑的来了，将写好的方法跑测试，发现存到了一些空的行，检查一下，发现返回的数据居然正常了，返回xml格式了，居然正常了，常了！！！！！！！！！！！

7、第三方哪个SaZi写的代码，老子想砍人~~~

8、下面是写的解决方法

9、专此记录一下被坑，屌丝何必为难屌丝
