正如Alex所说，为防止无限递归，您添加了此批注
@JsonIgnoreProperties(value = {"exchange"})@oneToMany(mappedBy = "exchange")private List<HalfFlow> halfFlows;所以我实际上通过在注释中添加以下内容解决了这个问题
@JsonIgnoreProperties(value = {"exchange"}, allowSetters = true)@oneToMany(mappedBy = "exchange")private List<HalfFlow> halfFlows;此解决方案在这里有更好的解释https://softwareengineering.stackexchange.com/questions/300115/best-
