spring - 将请求范围的 bean 转换为 JSON 字符串

Question

在使用对象映射器将具有请求范围的 bean 转换为 JSON 时，我遇到了一个问题。它会出现如下异常。不确定缺少什么。我在网上找不到任何相关的资源。有人可以解释一下应该怎么做。

提前致谢。

代码行：

planInfo -> 具有请求范围的 Bean

String json = new ObjectMapper().writeValueAsString(planInfo);

例外 ：

"timestampSeconds":1630567890,"timestampNanos":683000000,"severity":"ERROR","thread":"qtp133294616-216","logger":"com.signup.api.service.SignupService","message":"exception \ncom.fasterxml.jackson.databind.JsonMappingException: Infinite recursion (StackOverflowError) (through reference chain: jdk.internal.loader.ClassLoaders$PlatformClassLoader[\"unnamedModule\"]-\u003ejava.lang.Module[\"classLoader\"]-....
