java - com.fasterxml.jackson.databind.JsonMappingException : Numeric value (1557587751202) out of range of int

Question

我使用 Spring Initializr 生成了一个 Spring Boot Web 应用程序，在 macOS Sierra 中使用嵌入式 Tomcat + Thymeleaf 模板引擎，我必须在其中解析 Json 对象

我有一个具有此属性的域对象:

@JsonProperty("activationTime")
private BigInteger activationTime;

但是当我解析这个对象时出现这个错误:

com.fasterxml.jackson.databind.JsonMappingException: Numeric value (1557587751202) out of range of int

"tokenEnd":1557587751202

那是你的问题。 Java 中 int 的最大值为 2,147,483,647。将表示 tokenEnd 的任何类字段更改为(例如)long。
