Question

我尝试注入多个上下文来运行我的应用程序，但服务器崩溃了，我收到了以下日志错误：

'Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.batch.core.configuration.ListableJobLocator] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:1100)'

我检查了错误，我找到了一些详细信息here，但我在下面的代码中找不到错误：

要加载的上下文：

@ComponentScan
@EnableAutoConfiguration
@EnableJpaRepositories
@ImportResource("classpath:job-report.xml")
public class DBDataManipulatorServiceContext {


@Bean
public DataSource dataSource() {
    return new EmbeddedDatabaseBuilder().setName("aircraft").setType(H2).build();
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
    LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
    lef.setDataSource(dataSource);
    lef.setJpaVendorAdapter(jpaVendorAdapter);
    lef.setPackagesToScan("com");
    return lef;
}

@Bean
public JpaVendorAdapter jpaVendorAdapter() {
    HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
    hibernateJpaVendorAdapter.setShowSql(true);
    hibernateJpaVendorAdapter.setGenerateDdl(true);
    hibernateJpaVendorAdapter.setDatabase(Database.H2);
    return hibernateJpaVendorAdapter;
}

@Bean
public PlatformTransactionManager transactionManager() {
    return new JpaTransactionManager();
}

}

要导入的xml文件：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:batch="http://www.springframework.org/schema/batch"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:task="http://www.springframework.org/schema/task" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

">

<context:component-scan base-package="com" />

<!-- stored job-meta in memory -->
<bean id="jobRepository"
    class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean">
    <property name="transactionManager" ref="transactionManager" />
</bean>

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

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

<bean id="Aircraft" class="com.domain.Aircraft" scope="prototype" />

<bean id="customReader" class="com.batch.CustomReader" />

<bean id="customWriter" class="com.batch.CustomWriter" />

<batch:job id="reportJob">
    <batch:step id="step1">
        <batch:tasklet>
            <batch:chunk reader="customReader" writer="customWriter"
                commit-interval="10">
            </batch:chunk>
        </batch:tasklet>
    </batch:step>
</batch:job>

<bean id="runScheduler" class="com.RunScheduler" />

<!-- Run every Hour -->
<task:scheduled-tasks>
    <!-- <task:scheduled ref="runScheduler" method="run" fixed-delay="3600000" 
        /> -->
    <task:scheduled ref="runScheduler" method="run"
        cron="0 0 * * * *" />
</task:scheduled-tasks>

runScheduler是：

@Component
public class RunScheduler {

@Autowired
private JobLauncher jobLauncher;

@Autowired
private Job job;

public void run() {

    try {

        String dateParam = new Date().toString();
        JobParameters param = new JobParametersBuilder().addString("date", dateParam).toJobParameters();

        JobExecution execution = jobLauncher.run(job, param);
        System.out.println("Exit Status : " + execution.getStatus());

    } catch (Exception e) {
        e.printStackTrace();
    }

}

}

我的自定义阅读器：

public class CustomReader implements ItemReader<Map<Integer, Aircraft>> {

@Override
public Map<Integer, Aircraft> read() throws Exception, UnexpectedInputException,
        ParseException, NonTransientResourceException {

    HTMLDataExtractorService htmlDataExtractor = new HTMLDataExtractorService();

    Map<Integer, Aircraft> aircraftsMap = htmlDataExtractor.parsePage("/Sabri/DTDailyReport.html");

    return aircraftsMap;
}

}

和我的定制作者：公共类CustomWriter实现ItemWriter {

@Override
public void write(List<? extends Aircraft> aircrafts) throws Exception {

    DBDataManipulatorServiceImpl dbDataManipulatorImpl = new DBDataManipulatorServiceImpl();

    Map <Integer, Aircraft> aircraftsMap = null;

    for(Aircraft aircraft: aircrafts){
        aircraftsMap.put(aircraft.getAircraftId(), aircraft);
    }
    dbDataManipulatorImpl.saveToDataBase(aircraftsMap);

}}

抱歉没有任何不便，但有人能告诉我我的错误在哪里，我该如何解决这个问题？

Answer 1

在ApplicationContext.xml中添加以下条目，其中声明了jobLauncher和jobRegistry bean解决了我的问题

<bean id="jobRegistry"
    class="org.springframework.batch.core.configuration.support.MapJobRegistry" />

Answer 2

将@EnableBatchProcessing添加到您的配置中，这大致相当于使用XML命名空间

没有为依赖项找到类型的限定bean
