java - 尽管已在 xml 中初始化，但抱怨 BATCH_JOB_INSTANCE 的 Spring 批处理不存在

问题描述

我正在尝试创建一个非常简单的 Spring 批处理项目，以便对其有所了解。我正在干燥从 csv 文件中输入一个名为 user_details 的 oracle 表中的虚拟用户名和密码。

以下是我的database.xml文件

<?xml version="1.0" encoding="UTF-8"?>

</beans>

我的应用程序类看起来像这样

package com.springbatch;

import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Application {

    public static void main(String[] args) {
        String[] springConfig  = 
            {   "config/database.xml", 
                "config/job-report.xml" 
            };

        ApplicationContext context = 
                new ClassPathXmlApplicationContext(springConfig);
        JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
        Job job = (Job) context.getBean("userDetailsJob");
        try {
            JobExecution execution = jobLauncher.run(job, new JobParameters());
            System.out.println("Exit Status : " + execution.getStatus());
        }catch(Exception e){
            e.printStackTrace();
        }
        System.out.println("Batch Done");
    }

}

用户详情模型如下

package com.springbatch.model;

public class UserDetails {

    private String username;
    private String password;
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }



}

我的pom.xml文件在下面

但我一直在下面遇到这个错误，

Batch Done

我不确定出了什么问题，我在这里缺少什么，我将非常感谢您对此的投入。

解决方案

这是job-report.xml解决我的问题的修改，另外，我必须通过运行批处理核心中提供的脚本手动创建 oracle 批处理表。
