我用的是Sping Boot ，H2数据库
我要求是将json字符串存储到数据库中。
下面是我的实体类

import org.json.JSONObject;

@Entity
@Table(name = "TABLE_JSON")
public class DataJson {

    @Id
    @Type(type = "uuid-char")
    @GeneratedValue(generator = "UUID")
    @GenericGenerator(name = "UUID", strategy = "org.hibernate.id.UUIDGenerator")
    @Column(name = "id", updatable = false, nullable = false)
    private UUID id;

    @NonNull
    private String check;

    @NonNull
    @Column(columnDefinition = "TEXT")
    @Convert(converter= JSONObjectConverterForMe.class)
    private JSONObject json_data;

}

下面是Converter类

import org.json.JSONObject;

@Converter
public class JSONObjectConverterForMe implements AttributeConverter<JSONObject, String> {
    @Override
    public String convertToDatabaseColumn(JSONObject jsonData) {
        String json;
        try{
            json = jsonData.toString();
        }
        catch (NullPointerException ex)
        {
            //extend error handling here if you want
            json = "";
        }
        return json;
    }

    @Override
    public JSONObject convertToEntityAttribute(String jsonDataAsJson) {
        JSONObject jsonData;
        try {
            jsonData = new JSONObject(jsonDataAsJson);
        } catch (JSONException ex) {
            //extend error handling here if you want
            jsonData = null;
        }
        return jsonData;
    }
}

当我运行spring Boot 应用程序时，我得到了以下错误

org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table TABLE_JSON (id varchar(255) not null, check varchar(255), json_data TEXT, primary key (id))" via JDBC Statement

check是一个SQL Reserved keyword，所以你不能使用check作为一个没有引号/反勾的列名。默认情况下，Hibernate在查询中不使用引号/反勾作为列名。你可以这样显式地使用反勾/引号

@Column(name="`check`")
private String check;

在某些数据库中，反勾不起作用，例如：postgresql对它们使用引号

@Column(name="\"check\"")
private String check;

或者，您可以在配置文件中使用此命令，强制Hibernate对列名和表名使用引号

hibernate.globally_quoted_identifiers=true

您还应该指定id列的长度，默认情况下为255，这会产生问题。

@Column(name = "id", length = 36 , updatable = false, nullable = false)
private UUID id;

我认为您正在尝试使用SQL关键字（check）作为列名。请尝试使用其他名称命名该列：

@NonNull
@Column(name="another_column_name")
private String check;

我也遇到了同样的问题，最后我意识到。我的表名是保留关键字。请不要在postgresql中使用保留关键字作为表名，列名。
