这是一个 Spring 框架的异常,通常是由于类型转换错误导致的。具体来说,这个异常是由于将一个字符串类型转换为带有 @JsonFormat 注解的类型时失败了。@JsonFormat 注解用于指定 JSON 序列化和反序列化时使用的日期格式,如果你尝试将一个字符串转换为带有此注解的类型,但字符串格式不符合指定的日期格式,就会抛出此异常。解决此问题的方法是确保传递给类型转换的字符串符合指定的日期格式,或者将 @JsonFormat 注解从类型中移除。希望这能回答你的问题。

这个错误通常是由于Spring Boot 2.6.x与Swagger 3.0.0版本之间的冲突引起的。解决这个问题的方法有以下几种:
1. 在服务的application.properties配置中添加如下配置: # 处理SpringBoot2.6.x与Swagger2 3.0.0版本冲突 spring.mvc.pathmatch.matching-strategy=ant_path_matcher
2. 降低Swagger2的版本,可以将Swagger2的版本降低到2.9.2,但这可能会影响到其他功能。
3. 将Spring Boot版本降低到2.6以下,这也是一种解决方法。
