Property has no getter method json
场景:错误:JSON: property "xxx" has no getter method in class
异常:JSON: property "xxx" has no getter method in class
异常:JSON: property "xxx" has no getter method in class
异常:JSON: property "xxx" has no getter method in class ""
解决:声明bean为public class xxx,必须是public,我用默认类型(class xxx)都不行
