使用springMVC框架，controller类post方法接收实体bean对象参数时常用两种方式@RequestBody和@ModelAttribute：
1、参数前为：@RequestBody
fiddler配置：
POST请求头：
Content-Type: application/json
User-Agent: Fiddler
Accept-Language: zh-CN,zh;q=0.8
X-Requested-With: XMLHttpRequest
Host: localhost:8080
Content-Length: 44
Request Body：
{"mobile":"xxxxxxxxxxx","password":"123456"}
2、参数前为：@ModelAttribute
fiddler配置：
POST请求头：
Content-Type: application/x-www-form-urlencoded
User-Agent: Fiddler
Accept-Language: zh-CN,zh;q=0.8
X-Requested-With: XMLHttpRequest
Host: localhost:8080
Content-Length: 34
