Question

我已经通过了Spring Batch Framework - Auto create Batch Table之类的许多链接，并尝试了许多选项，但对我而言仍然无效。

我正在使用Spring Boot项目。

我不想在现有的Oracle数据库上创建 Spring Batch元数据表。我只是在开发使用Spring Batch将数据从Oracle迁移到MongoDB的实用程序。

当我执行代码时-

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [SELECT JOB_INSTANCE_ID, JOB_NAME from BATCH_JOB_INSTANCE where JOB_NAME = ? and JOB_KEY = ?]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist
] with root cause

java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist

application.properties

spring.batch.initialize-schema =从不

更新:: 现在，我无法在MYSQL上创建Spring Batch表。

您可以将Spring批处理元数据存储在其他数据库中，例如基于文件或内存的数据库，例如HSQL，请参阅示例XML配置

    <bean id="dataSourceBatchJob" class="org.apache.commons.dbcp.BasicDataSource"
    lazy-init="true" destroy-method="close">
    <property name="driverClassName" value="org.hsqldb.jdbc.JDBCDriver" />
    <property name="url"
        value="jdbc:hsqldb:file:batchdbspring/batchcore.db;hsqldb.default_table_type=cached;shutdown=true;hsqldb.sqllog=0;hsqldb.log_data=false;hsqldb.log_size=50;hsqldb.reconfig_logging=false" />
    <property name="username" value="sa" />
    <property name="password" value="" />
</bean>

<jdbc:initialize-database data-source="dataSourceBatchJob">
    <jdbc:script location="org/springframework/batch/core/schema-drop-hsqldb.sql" />
    <jdbc:script location="org/springframework/batch/core/schema-hsqldb.sql" />
</jdbc:initialize-database>

<bean id="jobRepository"
    class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
    <property name="transactionManager" ref="transactionManager" />
    <property name="databaseType" value="HSQL"></property>
    <property name="dataSource" ref="dataSourceBatchJob"></property>
</bean>

<bean id="jobExplorer"
    class="org.springframework.batch.core.explore.support.JobExplorerFactoryBean">
    <property name="dataSource" ref="dataSourceBatchJob" />
</bean>


<bean id="jobLauncher"
    class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
    <property name="jobRepository" ref="jobRepository" />
</bean>

嵌套异常是java.sql.SQLSyntaxErrorException：ORA-00942：表或视图不存在-如何避免创建Spring Batch元数据？
