映射 JSON 类型字段

定义 JSON 对应模型

示例代码

@Data
public static class MobilePhone {
    private String iddCode;
    private String phoneNumber;
    public MobilePhone(String iddCode, String phoneNumber) {
        this.iddCode = iddCode;
        this.phoneNumber = phoneNumber;
    }
}

定义模型与 JSON 转换

示例代码

package com.anydong.example.springboot.domain.converter;
import com.alibaba.fastjson.JSON;
import com.anydong.example.springboot.domain.UserDO;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;
/**
 * @author where
 */
@Converter(autoApply = true)
public class MobilePhoneConverter implements AttributeConverter<UserDO.MobilePhone, String> {
    @Override
    public String convertToDatabaseColumn(UserDO.MobilePhone mobilePhone) {
        return JSON.toJSONString(mobilePhone);
    }
    @Override
    public UserDO.MobilePhone convertToEntityAttribute(String s) {
        return JSON.parseObject(s, UserDO.MobilePhone.class);
    }
}

定义 JSON 类型字段

import javax.persistence.*;
@Convert(converter = MobilePhoneConverter.class)
@Column(columnDefinition = "JSON NULL")
private MobilePhone phone;
