我检查了我所有的模型，所有的属性都有getter和setter。
我可以通过添加spring.Jackson.serialization.fail-on-empty-beans =false来修复这个问题，但我认为这只是一个隐藏异常的解决方案。
在以下位置发生异常：类型定义错误：[简单类型，类组织。休眠。代理。pojo。Java辅助。Java辅助惰性初始化程序];嵌套的异常是com.fasterxml.Jackson.数据绑定.exc。无效定义异常：未找到类org. hib.proxy.pojo.javassist.JavassistLazyInitializer的序列化程序，也未发现用于创建BeanSerializer的属性（为避免异常，请禁用SerializationFeature.FAIL_ON_EMPTY_BEANS）（通过引用链：[0]-〉com.auzmor. platform. models. entities.雇员_$$_jvst80f_13 [“处理程序”]）
