java Spring Crudepository方法save无法解析方法

Question

在扩展spring Crudepository类时，它强制我从接口重写save方法。我无法在没有收到以下错误的情况下调用它：

我认为这是一个默认的方法，内置在接口中。我可以打电话给仓库。findAll（）成功，无需修改任何内容。你能解释一下吗

我的回购协议：

@Repository
@Component
public interface StorageItemRepository extends 
CrudRepository<StorageItemPersistenceModel, Long> {
}

我的模型：

 @Entity
 @Table(name = "StorageItem")
 public class StorageItemPersistenceModel {

/** Reference identifier. */
@Column(name = "ReferenceCode")
private String reference;

/** Date item was stored. */
@Column(name = "DateStored")
private DateTime dateStored;

/** Name of item. */
@Column(name = "Name")
private String name;

/** Item size. */
@Column(name = "Size")
private String size;

/** Image taken of item. */
@Column(name = "Image")
private byte[] image;


/**
 * Gets Image taken of item..
 *
 * @return Value of Image taken of item..
 */
public byte[] getImage() {
    return image;
}

/**
 * Gets Name of item..
 *
 * @return Value of Name of item..
 */
public String getName() {
    return name;
}

/**
 * Gets Date item was stored..
 *
 * @return Value of Date item was stored..
 */
public DateTime getDateStored() {
    return dateStored;
}

/**
 * Sets new Item size..
 *
 * @param size
 *         New value of Item size..
 */
public void setSize(String size) {
    this.size = size;
}

/**
 * Sets new Date item was stored..
 *
 * @param dateStored
 *         New value of Date item was stored..
 */
public void setDateStored(DateTime dateStored) {
    this.dateStored = dateStored;
}

/**
 * Gets Item size..
 *
 * @return Value of Item size..
 */
public String getSize() {
    return size;
}

/**
 * Sets new Image taken of item..
 *
 * @param image
 *         New value of Image taken of item..
 */
public void setImage(byte[] image) {
    this.image = image;
}

/**
 * Sets new Name of item..
 *
 * @param name
 *         New value of Name of item..
 */
public void setName(String name) {
    this.name = name;
}

/**
 * Sets new Reference identifier..
 *
 * @param reference
 *         New value of Reference identifier..
 */
public void setReference(String reference) {
    this.reference = reference;
}

/**
 * Gets Reference identifier..
 *
 * @return Value of Reference identifier..
 */
public String getReference() {
    return reference;
}

/**
 * Equals override.
 *
 * @param obj
 *         obj to compare.
 * @return equals boolean.
 */
@Override
public boolean equals(final Object obj) {
    if (!(obj instanceof StorageItemPersistenceModel))
        return false;
    if (obj == this)
        return true;

    StorageItemPersistenceModel storageItemControllerModel = (StorageItemPersistenceModel) obj;
    return new EqualsBuilder()
            .append(getDateStored(), storageItemControllerModel.getDateStored())
            .append(getReference(), storageItemControllerModel.getReference())
            .append(getName(), storageItemControllerModel.getName())
            .append(getSize(), storageItemControllerModel.getSize())
            .append(getImage(), storageItemControllerModel.getImage())
            .isEquals();
}

@Override
public String toString() {

    final StringBuilder stringBuilder = new StringBuilder();

    stringBuilder.append(reference).append(name).append(size).append(dateStored).append(image);

    return stringBuilder.toString();
}
