春天批次AsynchJob啓動，在設置作業回購

Question

錯誤

你好下面是我創建asynchlob發射

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

<bean id="taskExecutor" class="org.springframework.core.task.SimpleAsyncTaskExecutor" /> 

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean" /> 

我收到以下錯誤

我嘗試沒有&也正在配置。

誤差這樣

Report.java：

import javax.xml.bind.annotation.XmlAttribute; 
import javax.xml.bind.annotation.XmlElement; 
import javax.xml.bind.annotation.XmlRootElement; 

@XmlRootElement(name = "record") 
public class Report { 

    private int id; 
    private String sales; 
    private int qty; 
    private String staffName; 
    private String date; 

    @XmlAttribute(name = "id") 
    public int getId() { 
     return id; 
    } 

    public void setId(int id) { 
     this.id = id; 
    } 

    @XmlElement(name = "sales") 
    public String getSales() { 
     return sales; 
    } 

    public void setSales(String sales) { 
     this.sales = sales; 
    } 

    @XmlElement(name = "qty") 
    public int getQty() { 
     return qty; 
    } 

    public void setQty(int qty) { 
     this.qty = qty; 
    } 

    @XmlElement(name = "staffName") 
    public String getStaffName() { 
     return staffName; 
    } 

    public void setStaffName(String staffName) { 
     this.staffName = staffName; 
    } 

    public String getDate() { 
     return date; 
    } 

    public void setDate(String date) { 
     this.date = date; 
    } 

    @Override 
    public String toString() { 
     return "Report [id=" + id + ", sales=" + sales 
        + ", qty=" + qty + ", staffName=" + staffName + "]"; 
    } 

} 

要運行中使用的servlet用下面的代碼：

 ApplicationContext context = 
     new ClassPathXmlApplicationContext("job.xml"); 

JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher"); 
Job job = (Job) context.getBean("helloWorldJob"); 

try { 

    org.springframework.batch.core.JobExecution execution = jobLauncher.run(job, new JobParameters()); 
    System.out.println("Exit Status : " + execution.getStatus()); 

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