我不知道为什么这个查询没有返回它所需要的任何值
SELECT JOB_INSTANCE_ID, JOB_NAME from BATCH_JOB_INSTANCE where JOB_NAME = ? and JOB_KEY = ?]
我的 application-test.properties 如下 -

spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

spring.jpa.database=h2
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
我在文件下为 BATCH_JOB_INSTANCE 创建了以下架构
schema.sqlCREATE TABLE BATCH_JOB_INSTANCE (
JOB_INSTANCE_ID BIGINT GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY ,
VERSION BIGINT ,
JOB_NAME VARCHAR(100) NOT NULL,
JOB_KEY VARCHAR(32) NOT NULL,
constraint JOB_INST_UN unique (JOB_NAME, JOB_KEY)
) ;
好像和Spring Batch的一些内部类有关。你改变了SpringBoot版本或做了类似的事情吗？
首先确保正确配置了 DataSource、TransactionManager 和 JobRepository。
其次，我遇到了这个问题，当我在该行切换断点时，我看到?处的
id参数设置为0，而正确的作业ID是不同的值。这解释了为什么查询不返回任何内容。 由于上述配置而发生此错误的值设置。我正在迁移 SpringBoot，一些 BeanFactory 类（例如 MapJobRepositoryFactoryBean）已被弃用。将已弃用的类替换为弃用注释中推荐的类后，问题得到了解决。
