Question

我已经实现了Spring Batch作业存储库实现，以将作业元数据存储在一个数据库中。

配置永久作业存储库

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:batch="http://www.springframework.org/schema/batch" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/batch 
        http://www.springframework.org/schema/batch/spring-batch-2.2.xsd">

    <!-- stored job-meta in memory --> 

    <batch:job-repository id="jobRepository"
    data-source="dataSource"
    transaction-manager="transactionManager" />

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
        <property name="dataSource" ref="dataSource"/>
        </bean>

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

</beans>

database.xml如下： -

<beans xmlns="http://www.springframework.org/schema/beans"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns:jdbc="http://www.springframework.org/schema/jdbc"
            xsi:schemaLocation="http://www.springframework.org/schema/beans
                                                    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                                                    http://www.springframework.org/schema/jdbc
                                                    http://www.springframework.org/schema/jdbc/spring-jdbc.xsd">

    <!-- connect to database -->
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/sod_sustenance" />
        <property name="username" value="root"></property>
        <property name="password" value="root"></property>
    </bean>

    <bean id="oracleDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
        <property name="url" value="jdbc:oracle:thin:@internal.com:1533:vis" />
        <property name="username" value="system"></property>
        <property name="password" value="manager"></property>
    </bean>

    <!-- <bean id="transactionManager"
        class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" /> -->

    <!-- create job-meta tables automatically -->
    <jdbc:initialize-database data-source="dataSource">
        <jdbc:script location="org/springframework/batch/core/schema-drop-mysql.sql" />
        <jdbc:script location="org/springframework/batch/core/schema-mysql.sql" />
    </jdbc:initialize-database>


</beans>

运行应用程序后，表在MySQL中创建。但是我收到以下错误： -

由于此错误，无法插入值并且未插入作业元数据。

只是一次更新 - 在MySQL中创建了以下表结构： -

CREATE TABLE `batch_job_execution` (
  `JOB_EXECUTION_ID` bigint(20) NOT NULL,
  `VERSION` bigint(20) DEFAULT NULL,
  `JOB_INSTANCE_ID` bigint(20) NOT NULL,
  `CREATE_TIME` date DEFAULT NULL,
  `START_TIME` datetime DEFAULT NULL,
  `END_TIME` datetime DEFAULT NULL,
  `STATUS` varchar(10) DEFAULT NULL,
  `EXIT_CODE` varchar(100) DEFAULT NULL,
  `EXIT_MESSAGE` varchar(2500) DEFAULT NULL,
  `LAST_UPDATED` datetime DEFAULT NULL,
  PRIMARY KEY (`JOB_EXECUTION_ID`),
  KEY `JOB_INST_EXEC_FK` (`JOB_INSTANCE_ID`),
  CONSTRAINT `JOB_INST_EXEC_FK` FOREIGN KEY (`JOB_INSTANCE_ID`) REFERENCES `batch_job_instance` (`JOB_INSTANCE_ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

Answer 1

您可以尝试以下JDBC选项：

jdbcCompliantTruncation=false

Answer 2

您是否尝试使用Oracle作为job-repo元数据持有者并检查它是否有效？因为，如this线程中所述，可能是My SQL连接器驱动程序的问题。
