org.apache.openjpa.lib.jdbc.ReportingSQLException、MySQL、OpenJPA、Geronimo

Question

任何人都可以解释为什么我收到此错误（下面是完整的堆栈跟踪）：

由以下原因引起：org.apache.openjpa.lib.jdbc.ReportingSQLException：您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 1 行“TYPE = innodb”附近使用的正确语法** {stmnt 763763032 CREATE TABLE ADMIN_USER (admin_id BIGINT NOT NULL AUTO_INCRMENT,first_name VARCHAR(255),last_name VARCHAR(255) ), 用户名 VARCHAR(255), 主键 (admin_id))类型 = innodb} [代码=1064，状态=42000]*

我有一个带有 MySQL 5.5.11 和 openJPA 1.2.2 以及 Geronimo 的 Web 应用程序2.2.1 使用 Tomcat 6。我能够很好地解聚 .ear 。但是，当我提交表单以保留 Admin @Entity 时，我收到上面的以下错误。

另外，我使用 tranql-connector-mysql-local-1.5.rar（来自 Geronimo 存储库）作为我的连接器。

persistence.xml

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">
    <persistence-unit name="AReyesPersistUnit" transaction-type="JTA">
        <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
        <jta-data-source>AReyesMySql</jta-data-source>
        <class>com.areyes.entity.Admin</class>
        <properties>
            <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema"/>
        </properties>
    </persistence-unit>
</persistence>

Admin @Entity

@Entity
@Table (name="ADMIN_USER")
public class Admin implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue (strategy=GenerationType.IDENTITY)
    @Column (name="admin_id")private long id;
    @Column (name="user_name")private String userName;
    @Column (name="first_name")private String firstName;
    @Column (name="last_name")private String lastName;

...后跟 getters/setters

Answer 1

经过大量挖掘，这是一个已修复的错误。根本问题是 MySQL 在 5.1 左右的时间范围内将 table_option 'type' 更改为 'engine'。

您可以迁移到更新级别的 OpenJPA（1.3.x、2.0.x 等），或者不使用 OpenJPA 创建表。
