为Spring Batch应用初始化H2数据库
我使用Java 8新创建了Sprringboot批处理应用程序,我想为仅带附加说明的SpringBatch表创建一个数据库。
我想我必须创建配置文件,但我不知道如何做。
您可以在下面看到我希望在Java程序中使用注释重现的所有配置:
<!-- Base de donnees H2 pour les tables Spring Batch -->
<jdbc:embedded-database id="springBatchDataSource" type="H2">
<jdbc:script location="org/springframework/batch/core/schema-drop-h2.sql" />
<jdbc:script location="org/springframework/batch/core/schema-h2.sql" />
</jdbc:embedded-database>
<!-- TransactionManager Spring Batch -->
<bean id="springBatchTransactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />
<!-- JobRepository Spring Batch -->
<bean id="jobRepository" class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
<property name="dataSource" ref="springBatchDataSource" />
<property name="transactionManager" ref="springBatchTransactionManager" />
<property name="databaseType" value="H2" />
</bean>
我已经添加了以下代码:
@配置 公共类ConfigBatch{
@Bean(destroyMethod = "shutdown")
public EmbeddedDatabase dataSourceH2() {
return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2)
.addScript("classpath:org/springframework/batch/core/schema-drop-h2.sql")
.addScript("classpath:org/springframework/batch/core/schema-h2.sql").build();
}
@Bean
public SimpleJobLauncher jobLauncher() throws Exception {
final SimpleJobLauncher launcher = new SimpleJobLauncher();
launcher.setJobRepository(jobRepository());
return launcher;
}
@Bean
public JobRepository jobRepository() throws Exception {
final JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDatabaseType(DatabaseType.H2.getProductName());
factory.setDataSource(dataSourceH2());
factory.setTransactionManager(transactionManager());
return factory.getObject();
}
@Bean
public ResourcelessTransactionManager transactionManager() {
return new ResourcelessTransactionManager();
}
}
我的导入"@ImportResource"生成错误,因为我的Java代码中有一个数据源,XML文件中也有一个数据源:
未定义[javax.sql.DataSource]类型的限定Bean:需要单个匹配Bean,但找到2个:
我只想在H2数据源中生成Spring Batch表,并在Oracle数据源(XML导入资源)中运行Batch Writer。
你能帮我吗? 谢谢您:)
解决方案
将以下代码放入带有@Configuration批注的类中。
@Bean
public DataSource dataSource() {
EmbeddedDatabaseBuilder embeddedDatabaseBuilder = new EmbeddedDatabaseBuilder();
return embeddedDatabaseBuilder.addScript("classpath:org/springframework/batch/core/schema-drop-h2.sql")
.addScript("classpath:org/springframework/batch/core/schema-h2.sql")
.setType(EmbeddedDatabaseType.H2)
.build();
}
@Bean
public ResourcelessTransactionManager transactionManager() {
return new ResourcelessTransactionManager();
}
@Bean
public JobRepository jobRepository() throws Exception {
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDatabaseType(DatabaseType.H2.getProductName());
factory.setDataSource(dataSource());
factory.setTransactionManager(transactionManager());
return factory.getObject();
}
