ORMLite不知道如何存储java接口。util。列表

Question

产品

@DatabaseTable
public class Product implements Serializable {
private static final long serialVersionUID = 1L;

public Product() {
    // TODO Auto-generated constructor stub
}

public Product(String originalId) {
    this.originalId = originalId;
}

@DatabaseField(id = true)
private String originalId;

...

@DatabaseField
private List<SkuInfo> skusInfo;

SkuInfo

public class SkuInfo implements Serializable {

private static final long serialVersionUID = 1L;
...
}

错误是：

java.lang.IllegalArgumentException: ORMLite does not know how to store interface java.util.List for field skusInfo. Use another class or a custom persister.

当我使用：

@DatabaseField(dataType = DataType.SERIALIZABLE)
private List<SkuInfo> skusInfo;

错误更改为：

java.lang.IllegalArgumentException: ORMLite does not know how to store interface java.util.List for field skusInfo. Use another class or a custom persister.

我已经在另一篇帖子中读到了关于标签Foreign的内容，但我的物品不是外键

Answer 1

java.lang.IllegalArgumentException: ORMLite does not know how to store interface java.util.List for field skusInfo. Use another class or a custom persister.

就为了子孙后代，你可以把它改成一个ArrayList，它实际上实现了java.io.Serializable，因为这就是它想要的。不幸的是，List没有这样做，ORMLite抛出了异常

Answer 2

我使用了一个自定义的可序列化对象，比如posthere，并进行了工作

public class SerializableCollectionsType extends SerializableType {
    private static SerializableCollectionsType singleton;
    public SerializableCollectionsType() {
        super(SqlType.SERIALIZABLE, new Class<?>[0]);
    }

    public static SerializableCollectionsType getSingleton() {
        if (singleton == null) {
            singleton = new SerializableCollectionsType();
        }
        return singleton;
    }
    @Override
    public boolean isValidForField(Field field) {
        return Collection.class.isAssignableFrom(field.getType());
    }
}

产品

@DatabaseField(persisterClass = SerializableCollectionsType.class)
private List<SkuInfo> skusInfo;
