-----------------后台代码块-----------

后台：根据属性名获取对像的该属性值

InspectionStatistics object = new InspectionStatistics();
		
object.setCustomsCode("5131");
object.setFullName("tttttttt");

Field field = Class.forName("com.gzeport.app.cplatform.to.InspectionStatistics").getDeclaredField("fullName");
field.setAccessible(true);//设置私有变量允许访问
System.out.println(field.get(object));
