Java 如何使用Hibernate持久化枚举类型字段？
我有以下代码 回购 看法 Idk怎么了 schema.sqlJava 如何使用Hibernate持久化枚举类型字段？,java,spring,spring-boot,hibernate,Java,Spring,Spring Boot,Hibernate,我有以下代码 回购 看法 Idk怎么了 schema.sql create table if not exists component（id varchar（4）not null， 名称varchar（40）不为空，类型varchar（10）不为空）； data.sql > delete from Taco_Order_Tacos; delete from Taco_Ingredients; delete > from Taco; delete from Taco_Order; &
create table if not exists component（id varchar（4）not null，

类型是varchar类型，因此idk为什么我有数字异常我的表中没有任何数字您应该在
类型@Enumerated（EnumType.STRING）@枚举（EnumType.STRING）
私有最终类型；
