简单说明，这里是使用Gson将json字符串转换成功我们想要的list对象
需要转换的字符串
[{"id":2303,"goodsId":3817,"goodsName":"前腿肉 鲜猪肉","goodsNum":1,"orderNumber":"WPSN35012002102442753117000","orderSn":"WPSN35012002102442753117001","cost":0,"price":29,"allPrice":29,"costPrice":0,"smallPic":"https://test-1259235038.cos.ap-/user_2001110236_800x800%E4%BA%94%E8%8A%B1%E8%82%89.jpg","specDescribe":"1斤","specKey":"2001110427082","userId":123549}]
需要引用的jar包
<dependency><groupId>com.google.code.gson</groupId><artifactId>gson</artifactId><version>2.8.5</version></dependency>
代码操作
Gson gson = new Gson();List<WpOrderGoods> goods = gson.fromJson(goods1,new TypeToken<List<WpOrderGoods>>() {}.getType());
其中，goods1 就是需要装换的字符串；WpOrderGoods实体类为字符串所对应的属性值
WpOrderGoods类
private Integer id;private Integer goodsId;private String goodsName;private Integer goodsNum;private String orderNumber;private String orderSn;private BigDecimal cost;private BigDecimal price;private BigDecimal allPrice;private BigDecimal costPrice;private BigDecimal discountPrice;private String smallPic;private String specDescribe;private String specKey;private Long userId;private Byte isAppraise;private Integer specType;private Integer subattrId;private Byte isReply;private Byte isReturnApply;private Integer goodsShipTpl;private Date createTime;private BigDecimal goodsPrice;
注：get,set已省略
结果：
以上就是我要分享的内容，第一次写博客有问题的地方欢迎私聊
