Question

尝试运行Spring Batch代码时出现以下错误。我已经配置了JobRepository和JobLauncher，还配置了Job。通过main方法运行时出现以下错误

代码

<bean id="transactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
        <property name="url" value="jdbc:oracle:thin:@XX.YY.INT:1527/TEST" />
        <property name="username" value="TEST_USER" />
        <property name="password" value="BGFFFF" />
    </bean>

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

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

错误

log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

主要方法：

public class SendCustomerApp {

    public static void main(String[] args) throws JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException, JobParametersInvalidException {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath*:/META-INF/spring/ABC_context.xml");

        JobLauncher jobLauncher = (JobLauncher) applicationContext.getBean("jobLauncher");
        Job job = (Job) applicationContext.getBean("ABCJob");

        JobExecution execution = jobLauncher.run(job, new JobParameters());
        System.out.println("EXIT STATUS :: "+execution.getStatus());

        System.out.println("DONE !!");
    }
}

Answer 1

我创建了一个项目来测试您的代码，一切顺利。我只是将dataSource bean属性更改为连接到h2-db而不是Oracle。关于您的问题，请考虑，您粘贴了ABC_Job.xml内容，但是在您的代码中，您引用了ABC_context.xml，也许这是您的问题。顺便说一句，如果添加适当的记录器并设置日志级别进行调试，则可以查看spring创建的bean，还可以跟踪bean以找出问题的原因。

我能够通过使用FileSystemXMlApplication上下文解决以下问题。我坚信我正在使用的Maven项目的项目结构不正确，或者同时使用Boot和MainMethod。

public class MainApp {
    public static void main(String[] args) {
        PropertyConfigurator.configure("src/main/resources/log4j.properties");

        String[] springConfig = { "C:\\XXXX\\src\\main\\resources\\META-INF\\spring\\XXXXX-job.xml" };

        ApplicationContext context = new FileSystemXmlApplicationContext(springConfig);
        JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
        Job job = (Job) context.getBean("XXXJob");

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

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

        System.out.println("Done");
    }
}

线程“主” org.springframework.beans.factory.NoSuchBeanDefinitionException：没有定义名为“ jobLauncher”的bean
