前提:我是 Spring 季批次新手 .
我'm trying to customize the spring batch admin but , till now, i'我无法让我的类从外部文件中读取一些属性 .
我的作业从第三方数据库中提取数据以打印报告,因此我需要两个数据源:一个用于收集报告信息,另一个用于存储作业的状态和元数据 .
我已经阅读了教程:http://docs.spring.io/spring-batch-admin/reference/customization.html
和许多其他教程和以下帖子load external config file in spring batch admin .
然而,我无法启动该应用程序 . 它必须在Tomcat 6上运行 .
这是我的项目树的屏幕截图,由官方示例改编:
这是我的配置类:
@Configuration
@EnableBatchProcessing
public class RegistroGiornalieroConfiguration extends DefaultBatchConfigurer {
private final static Logger log = LoggerFactory.getLogger(RegistroGiornalieroConfiguration.class);
private final static Date data = null;
@Autowired
public JobBuilderFactory jobFactory;
@Autowired
public StepBuilderFactory stepFactory;
@Autowired
VolumiPropertySource volumiPropertySource;
@Value("${batch.jdbc.driver}")
private String driverName;
/**
* datasource di default, viene resitituito dall'annotazione Autowired
* @return
* @throws SQLException
*/
@Bean(name="springBatchDatasource")
@Primary
public DataSource springBatchDatasource() throws SQLException {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(driverName);//"com.mysql.jdbc.Driver");
// dataSource.setUrl(env.getProperty("springBatchUrl"));//"jdbc:mysql://localhost/spring_batch_annotations");
// dataSource.setUsername(env.getProperty("springBatchUser"));//"root");
// dataSource.setPassword(env.getProperty("springBatchPassword"));//"root");
return dataSource;
}
/**

*/
@Bean(name="estarDatasource")
public DataSource estarDatasource() throws SQLException {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(driverName);//"com.mysql.jdbc.Driver");

return dataSource;
}
// @PostConstruct

@Bean
@StepScope
public JdbcCursorItemReader<RegistroGiornaliero> reader(
@Value("#{jobParameters[data]}")
Date data)
{
System.out.println("reader");
// select protocol.nprotoc,protocol.dataprot,protocol.arrpar,protocol.numdoc,

JdbcCursorItemReader<RegistroGiornaliero> reader = new JdbcCursorItemReader<RegistroGiornaliero>();
try {
reader.setDataSource(estarDatasource());
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
reader.setPreparedStatementSetter(new ParameterSetter(data));
reader.setSql(sb.toString());
reader.setRowMapper(estarRowMapper());
reader.setVerifyCursorPosition(false);
return reader;
}
@Bean
public RegistroGiornalieroProcessor processorGenerazioneRegistro() {
return new RegistroGiornalieroProcessor();
}
@Bean
public ItemWriter<RegistroGiornaliero> pdfwriter() {
return new PDFItemWriter<RegistroGiornaliero>();
}
@Bean
public JobExecutionListener listener() {
return new JobCompletionNotificationListener();
}
@Bean
public RegistroGiornalieroRowMapper estarRowMapper() {
return new RegistroGiornalieroRowMapper();
}
@Bean
public Job generaRegistroGiornaliero()
{
return jobFactory
.get("generaRegistroGiornaliero")
.incrementer(new RunIdIncrementer())
.flow(leggiDocumentiProtocollo())
.end()
.build();
}
@Bean
public Step leggiDocumentiProtocollo()
{
return stepFactory.get("leggiDocumentiProtocollo")
.<RegistroGiornaliero, RegistroGiornaliero> chunk(10)
.reader(reader(data))
.processor(processorGenerazioneRegistro())
.writer(pdfwriter())
.build();
}
@Override
public JobRepository getJobRepository() {
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
// use the autowired data source
try {
factory.setDataSource(springBatchDatasource());
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
factory.setTransactionManager(getTransactionManager());
try {
factory.afterPropertiesSet();
return factory.getObject();
} catch (Exception e) {
// TODO Auto-generated catch block
//e.printStackTrace();
}
return null;
}
}
这是我的工作配置(registrogiornaliero.xml):
<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd

http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<context:annotation-config/>
<context:component-scan base-package="it.infogroup.estav.registrogiornaliero"/>
</beans>
最后这是我的env.xml,如stackoverflow帖子:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
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.xsd">
<!-- Use this to set additional properties on beans at run time -->
<bean id="placeholderProperties"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:/org/springframework/batch/admin/bootstrap/batch.properties</value>
<value>classpath:batch-default.properties</value>
<!-- <value>classpath:batch-${ENVIRONMENT:hsql}.properties</value>-->
<value>classpath:batch-${ENVIRONMENT:mysql}.properties</value>
<!-- here we load properties from external config folder -->
<value>file:${app.conf}</value>
</list>
</property>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="ignoreResourceNotFound" value="false" />
<property name="ignoreUnresolvablePlaceholders" value="false" />
<property name="order" value="1" />
</bean>
</beans>
任何帮助将不胜感激

免责声明:我是 Spring 季批次的新手,因此这不是最好的解决方案:
http://www.springframework.org/schema/beans/spring-beans.xsd“>
$ 是一个jvm参数 .
2.我已经用占位符变量es替换了Environment类的使用 . :
问题2:多个数据源,有很多帖子描述了不同的解决方案,包括重写DefaultBatchConfigurer类及其getJobRepository方法 .
对我有用的唯一解决方案是添加
到Use of multiple DataSources in Spring Batch中描述(并清楚解释)的配置类
并覆盖data-source-context.xml文件:我把它放在/ src / main / resources / META-INF / spring / batch / override /下 .
其内容是:
希望这有助于其他一些初学者,我很高兴知道这是否是一个合适的解决方案,并最终如何将属性读入Environment类 .
