我有一个 Spring Boot 应用程序，使用 Azul 的 2.2.4 版和 Zulu Java 11.0.5。它正在访问部署在 Payara Web 服务器（版本 5.194）上的 REST Web 服务。

我正在使用以下 DTO：

public class IdDTO extends BasicResponseDTO {
    private long id;

    public IdDTO(long id) {
        this.id = id;
    }

    public long getId() {
        return id;
    }

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

}

和

public class BasicResponseDTO implements Serializable {

    private String errorCode;

    public BasicResponseDTO() {
        this.setErrorCode(null);
    }

    public String getErrorCode() {
        return errorCode;
    }

    public void setErrorCode(String errorCode) …

我有一个JPA应用程序使用Hibernate而不是JDBC和MySQL,没有任何应用程序服务器.

在我的persistence.xml中,我已经定义了从脚本创建,加载和删除数据库的规则:

<property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
<property name="javax.persistence.schema-generation.create-source" value="script"/>
<property name="javax.persistence.schema-generation.create-script-source" value="META-INF/scripts/create.sql" />
<property name="javax.persistence.sql-load-script-source" value="META-INF/scripts/load.sql" />
<property name="javax.persistence.schema-generation.drop-source" value="script" />
<property name="javax.persistence.schema-generation.drop-script-source" value="META-INF/scripts/drop.sql" />

但是,当Maven测试目标执行时,我收到以下错误:

无法执行JPA模式生成create命令[CREATE TABLE country(]

堆栈跟踪看起来像这样:
