Jsonlib使用PropertyNameProcessor处理属性首字母为大写的情况

User：

package com.zzj.jsonlib.vo;import java.util.List;import com.zzj.jsonlib.vo.user.Order;public class User {private String Username;private String Password;private List<Order> OrderList;public User() {}public User(String username, String password) {Username = username;Password = password;}public String getUsername() {return Username;}public void setUsername(String username) {Username = username;}public String getPassword() {return Password;}public void setPassword(String password) {Password = password;}public List<Order> getOrderList() {return OrderList;}public void setOrderList(List<Order> orderList) {OrderList = orderList;}@Overridepublic String toString() {return "User [Username=" + Username + ", Password=" + Password+ ", OrderList=" + OrderList + "]";}}

Order：

package com.zzj.jsonlib.vo.user;public class Order {private String OID;private String OrderStatus;private Address Address;public String getOID() {return OID;}public void setOID(String oID) {OID = oID;}public String getOrderStatus() {return OrderStatus;}public void setOrderStatus(String orderStatus) {OrderStatus = orderStatus;}public Address getAddress() {return Address;}public void setAddress(Address address) {Address = address;}@Overridepublic String toString() {return "Order [OID=" + OID + ", OrderStatus=" + OrderStatus+ ", Address=" + Address + "]";}}

Address：

package com.zzj.jsonlib.vo.user;public class Address {private String State;public String getState() {return State;}public void setState(String state) {State = state;}@Overridepublic String toString() {return "Adrress [State=" + State + "]";}}
