Question

我是hibernate的新手。我试图映射以下实体，但获得hibernate映射异常。将非常感谢帮助。记住，Iam使用PostgreSQL

package st.malike.auth.server.model;

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import org.springframework.security.oauth2.common.OAuth2RefreshToken;
import org.springframework.security.oauth2.provider.OAuth2Authentication;


@Entity
public class OAuth2AuthenticationRefreshToken implements Serializable {

//    @Indexed
    @javax.persistence.Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String id;
    private final String tokenId;
    private final OAuth2RefreshToken oAuth2RefreshToken;
    private final OAuth2Authentication authentication;

    public OAuth2AuthenticationRefreshToken(OAuth2RefreshToken oAuth2RefreshToken, OAuth2Authentication authentication) {
        this.oAuth2RefreshToken = oAuth2RefreshToken;
        this.authentication = authentication;
        this.tokenId = oAuth2RefreshToken.getValue();
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getTokenId() {
        return tokenId;
    }

    public OAuth2RefreshToken getoAuth2RefreshToken() {
        return oAuth2RefreshToken;
    }

    public OAuth2Authentication getAuthentication() {
        return authentication;
    }
}

如下所示获得例外

Answer 1

如果您没有保存属性oAuth2RefreshToken的任何值，请添加注释@Transient以忽略与数据库的任何映射。

如果您有一些地图，请将其添加到您的问题

Answer 2

在您的OAuth2RefreshToken (OAuth2AccessToken)类中将接口DefaultOAuth2RefreshToken (DefaultOAuth2AccessToken)更改为Entity。 DefaultOAuth2RefreshToken (DefaultOAuth2AccessToken)是类，但不是接口。 Postgres BD将其另存为BYTEA。

最后，我邀请您阅读此Hibernate链接，以便了解可以在其中使用该实体模型的POJO模型。休眠https://docs.jboss.org/hibernate/orm/5.4/userguide/html_single/Hibernate_User_Guide.html#entity-pojo
