此特别信息在开发之历程中为每每的可看得到，当然也是比较简单的十分。在非常的音信遭受比了解的指明了诱惑那个的故There
is no getter for property named ’empid’ in ‘class
cn.happy.entity.Emp’，找到呼应的MODEL看看有没起相应之性能和相应的SET和GET
方法！我此是紧缺相应的性质，也常有未曾相应之SET和GET方法！
只是用注意的是：在MyBatis映射文件中因故#跟$传递参数的风味，#凡是因占位符的形式来传递对应变量的参数值的，框架会指向传播的参数做预编译的动作，用$时会将盛传的变量的参数值原样的传递过去，并且因此$传递传递参数的时刻要出对应之GET方法，在MyBatis的照射文件被而因此有变量传递传递参数，这个变量必须有让对应的范中，并且发生照应的GET方法！此点时引起莫名的十分问题，要多加留心！
重要原因，其实是实体类的字段大小写及if语句里的字段大小写不一样!
