高級(jí)適配玩法攒巍，上面那種方法需要一個(gè)枚舉對(duì)應(yīng)一個(gè)轉(zhuǎn)換類很麻煩
基礎(chǔ)枚舉轉(zhuǎn)換類
package com.gecko.charging.common.jpaenum.converter;
import com.gecko.charging.common.BaseEnum;
import javax.persistence.AttributeConverter;
import java.lang.reflect.Method;
import java.lang.reflect.ParameterizedType;
public class BaseEnumConverter <X extends BaseEnum<Y>, Y> implements AttributeConverter<BaseEnum<Y>, Y> {
private Class<X> xclazz;
private Method valuesMethod;
@SuppressWarnings("unchecked")
public BaseEnumConverter() {
this.xclazz = (Class<X>) (((ParameterizedType) this.getClass().getGenericSuperclass())
.getActualTypeArguments())[0];
try {
valuesMethod = xclazz.getMethod("values");
} catch (Exception e) {
throw new RuntimeException("can't get values method from " + xclazz);
}
}
@Override
public Y convertToDatabaseColumn(BaseEnum attribute) {
return attribute == null ? null : (Y) attribute.getCode();
}
@SuppressWarnings("unchecked")
@Override
public X convertToEntityAttribute(Y dbData) {
try {
X[] values = (X[]) valuesMethod.invoke(null);
for (X x : values) {
if (x.getCode().equals(dbData)) {
return x;
}
}
} catch (Exception e) {
throw new RuntimeException("can't convertToEntityAttribute" + e.getMessage());
}
throw new RuntimeException("unknown dbData " + dbData);
}
}
枚舉基礎(chǔ)類
package com.gecko.charging.common;
public interface BaseEnum<Y> {
Y getCode();
static BaseEnum[] getValues() {
return new BaseEnum[0];
}
}
枚舉
package com.gecko.charging.device.enums;
import com.alibaba.fastjson.annotation.JSONType;
import com.gecko.charging.common.BaseEnum;
import com.gecko.charging.util.json.EnumDeserializer;
import com.gecko.charging.util.json.EnumSerializer;
/**
* 設(shè)備歸屬枚舉
*/
@JSONType(serializer = EnumSerializer.class, deserializer = EnumDeserializer.class, serializeEnumAsJavaBean = true)
public enum DeviceOwnerType implements BaseEnum<Integer> {
PLATFORM(1),// 平臺(tái)
PROPERTY(2),// 物業(yè)商
FRANCHISEE(3),// 加盟商
;
private Integer code;
DeviceOwnerType(Integer code) {
this.code = code;
}
@Override
public Integer getCode() {
return code;
}
public static class Convert extends BaseEnumConverter<DeviceOwnerType, Integer> {
}
}
實(shí)體類 需要加注解 @Convert(converter = DeviceOwnerType.Convert.class)
package com.gecko.charging.device.entity;
import com.gecko.charging.device.enums.*;
import com.meenoframework.common.BaseEntity;
import lombok.AllArgsConstructor;

import java.util.Date;
/**

@Entity

@AllArgsConstructor
@EntityListeners(AuditingEntityListener.class)
public class ChargingDevice extends BaseEntity {

@Convert(converter = DeviceOwnerType.Convert.class)
private DeviceOwnerType ownerType;

private Long creatorId;
@CreatedDate

private Date updateTime;
// 上線時(shí)間

}
@Convert(converter = DeviceOwnerType.Convert.class)
使用這個(gè)注解配置生效!
