我正在使用Spring的BeanPropertyRowMapper将来自数据库的行映射到我的Bean类Employee，Enum有2种类型，Active，Inactive。 当 beanpropertyrowmapper 尝试将来自数据库的字符串转换为我的枚举时，它会失败。 (Enum 是类中的 empStatus 作为 Enum，并在数据库中声明为 String)。
我不想为每个服务编写自定义行映射器，我需要一些通用解决方案来映射相关类的枚举。 这是我的 Employee 类。

最佳答案
如果您不想将列类型更改为enum，则应使用EnumType.String。
@Enumerated(EnumType.STRING)
//@Column(name = "name of the column to map with")
@JsonProperty("empStatus")
private EmpStatusEnum empStatus;
关于java - 无法将 'java.lang.String' 的值转换为所需类型 'myEnum'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53002077/
