解决方案

运行到gson解析JSON时报如上异常，代码没变，为什么在不同服务器上运行的结果就不一样了呢，后来各种搜索，才了解到Gson不同服务器在解析时间格式不一样，了解到这一点后，只需要在Gson实例化指定解析的格式即可，将

Gson gson=new Gson();替换为 Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create();

最终代码实现

对应测试的javabean

@Data
@AllArgsConstructor
@NoArgsConstructor
@Accessors(chain = true)
public class DemoOne {
    private Integer id;
    private String userName;
    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date bir;
    private Double salary;
}
