是否可以在纯 JPA 中进行类型转换(从布尔到 yes_no)? [英] Is it possible to do type conversion (from boolean to yes_no) in pure JPA?

问题描述

Hibernate 中有一个注解可以在数据库中将布尔类型持久化为Y"/N".

There is an annotation in Hibernate that can persist boolean types as 'Y'/'N' in the database.

但是，如果我不想绑定到 Hibernate，有没有办法在纯 JPA 中做到这一点而不使用 getter/setter?

However if I don't want to bind to Hibernate is there a way to do it in pure JPA without using getters/setters?

推荐答案

Pure JPA without Hibernate 是通过某种转换实现的

Pure JPA without Hibernate is achieved by using some kind of conversion

private boolean enabled;

@Transient
public boolean isEnabled() {
    return this.enabled;
}
public void setEnabled(boolean enabled) {
    this.enabled = enabled;
}

@Column(name="ENABLED")
public String getEnabledAsString(){
    return enabled ? "Y" : "N";
}

public void setEnabledAsString(String enabled){
    this.enabled = "Y".equalsIgnoreCase(enabled);
}

没有别的
