报错JSON parse error: Cannot deserialize value of type `java.lang.Integer` from String

前端界面报错
JSON parse error: Cannot deserialize value of type java.lang.Integer from String “77777777777”: Overflow: numeric value (77777777777) out of range of Integer (-2147483648 - 2147483647); nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type java.lang.Integer from String “77777777777”: Overflow: numeric value (77777777777) out of range of Integer (-2147483648 - 2147483647) at [Source: (PushbackInputStream); line: 1, column: 121] (through reference chain: com.weilanaoli.ruge.base.client.vo.ProjectVO[“floorSpace”])
解决思路
在检查了验证规则以及输入框最大长度没有错误之后,可以看看是否是接口问题,
答案就是接口报错503,那么这个问题就是要找后端了。
