Spring boot、JPA、Hibernate 和 H2 DB 测试 - 序列不起作用 - 意外的代码路径”；SQL 语句：调用 seq_my_jobs [50000-193] 的下一个值

问题描述 投票：0回答：1

我的 Spring Boot 应用程序上有一个实体：

@Entity
@Table(name = "MY_JOBS")
public class InstallationJobEntity {

    @GeneratedValue(generator="SEQUENCE_GENERATOR", strategy = GenerationType.SEQUENCE)
    @SequenceGenerator(name="SEQUENCE_GENERATOR",sequenceName="SEQ_MY_JOBS", allocationSize=100)
    @Id
    @Column(name = "ID")
    private Long id;

    @Column(name = "CONFIGURATION_DATA")
    @Lob
    private String configurationData;

    public Long getId() {
        return id;
    }

    public String getConfigurationData() {
        return configurationData;
    }

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

    public void setConfigurationData(String configurationData) {
        this.configurationData = configurationData;
    }
}

为了进行测试，我在 application.yml 上配置 H2 DB：

spring:
    jpa:
        database: H2
        show-sql: true
        hibernate:
            ddl-auto: none
    properties:
        hibernate:
            dialect: common.H2Dialect
    datasource:
        initialize: true
        schema: schema.sql
        data: data.sql
        url: jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;Mode=Oracle;DATABASE_TO_UPPER=false;
        username:
        platform: h2
        driver-class-name: org.h2.Driver
        testWhileIdle: true
        validationQuery: SELECT 1 from DUAL

在 schema.sql 上，我创建表和序列（我直接使用 JdbcTemplate 对其进行了测试，它正在工作）

运行测试时出现此异常：

2017-02-10 15:07:47.764 ERROR 22618 --- [           main] o.h.engine.jdbc.spi.SqlExceptionHelper   : General error: "java.lang.RuntimeException: Unexpected code path"; SQL statement:

主要问题是： 引起：org.h2.jdbc.JdbcSQLException：一般错误：“java.lang.RuntimeException：意外的代码路径”； SQL语句： 调用 seq_my_jobs [50000-193] 的下一个值

我还尝试实现我自己的 H2 方言（所有注释的代码都不起作用......）：

public class H2Dialect extends org.hibernate.dialect.H2Dialect {
@Override
public String getSequenceNextValString(String sequenceName) {
//        return "SELECT "+ sequenceName + ".nextval";
//        return "SELECT "+sequenceName+".nextval from DUAL";
//        return "SELECT "+"NEXTVAL('"+sequenceName+"')";
        return "SELECT SEQ_MY_JOBS.nextVal from DUAL";
    }

}

有什么想法吗？

hibernate jpa spring-boot sequence h2

由于您在 Oracle 兼容模式下运行 H2 

Mode=Oracle
，请使用 oracle 方言：

 properties:
        hibernate:
            dialect: org.hibernate.dialect.Oracle10gDialect
