JSON转对象（实体类对象）

1、创建对象

import java.io.Serializable;
import com.alibaba.fastjson.annotation.JSONField;
public class PushMsgContent implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;

private String amt1;// 本金 amt1
private String amt2;// 放款金额 amt2
private String amt3;// 应还本利合计为 amt3

@JSONField(name = "amt1")//对应json中的key值
public String getAmt1() {
return amt1;
}
public void setAmt1(String amt1) {
this.amt1 = amt1;
}
@JSONField(name = "amt2")
public String getAmt2() {
return amt2;
}
public void setAmt2(String amt2) {
this.amt2 = amt2;
}
@JSONField(name = "amt3")
public String getAmt3() {
return amt3;
}
public void setAmt3(String amt3) {
this.amt3 = amt3;
}
}


2、使用alibabajson把json字符串转对象import com.alibaba.fastjson.JSON;
String msgContent = "{json字符串}";
PushMsgContent pushMsgContent =  JSON.parseObject(msgContent,PushMsgContent.class);
