本文介绍了2个示例，即从mysql中读取数据写入文本和从多个文本中读取内容写入mysql。
本文使用的是jdk版本，最新版本的spring core和springb batch用不了。

一、示例1：从mysql中读取数据写入txt文件

1、maven依赖

		<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<springframework.version>5.2.25.RELEASE</springframework.version>
		<joda-time.version>2.12.5</joda-time.version>
		<mysql.connector.version>5.1.31</mysql.connector.version>
		<springbatch.version>4.2.8.RELEASE</springbatch.version>

	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.batch</groupId>
			<artifactId>spring-batch-core</artifactId>
			<version>${springbatch.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework.batch</groupId>
			<artifactId>spring-batch-infrastructure</artifactId>
			<version>${springbatch.version}</version>
		</dependency>
		<dependency>

			<version>${springframework.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-oxm</artifactId>
			<version>${springframework.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jdbc</artifactId>
			<version>${springframework.version}</version>
		</dependency>
		<dependency>
			<groupId>joda-time</groupId>
			<artifactId>joda-time</artifactId>
			<version>${joda-time.version}</version>
		</dependency>
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>${mysql.connector.version}</version>
		</dependency>
	</dependencies>

2、创建mysql 表并插入数据

DROP TABLE IF EXISTS `personinfo`;
CREATE TABLE `personinfo`  (
  `name` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `birthday` varchar(15) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `salary` double NOT NULL
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of personinfo
-- ----------------------------
INSERT INTO `personinfo` VALUES ('alanchanchn', '1985-02-01', 76);
INSERT INTO `personinfo` VALUES ('alan', '1979-09-01', 91.5);
INSERT INTO `personinfo` VALUES ('chan', '1993-03-01', 92);
INSERT INTO `personinfo` VALUES ('alanchan', '1995-08-01', 83);

SET FOREIGN_KEY_CHECKS = 1;

3、PersonInfo bean

import lombok.Data;

/**
 * @author alanchan
 *
 */
@Data
public class PersonInfo {
    
    
	private String name;
	private String birthday;
	private double salary;
}

4、建立RowMapper

import java.sql.ResultSet;
import java.sql.SQLException;

import org.springframework.jdbc.core.RowMapper;

import com.win.mysql2xml.bean.PersonInfo;

/**
 * 
 * @author alanchan
 *
 */
public class PersonInfoRowMapper implements RowMapper<PersonInfo> {
    
    

	public PersonInfo mapRow(ResultSet rs, int rowNum) throws SQLException {
    
    
		PersonInfo personInfo = new PersonInfo();
		personInfo.setName(rs.getString("name"));
		personInfo.setBirthday(rs.getString("birthday"));
		personInfo.setSalary(rs.getDouble("salary"));

		return personInfo;
	}

}

5、创建ItemProcessor实现类

本示例仅仅是过滤一下，salary小于77的设置为salary*1.3。

import org.springframework.batch.item.ItemProcessor;

import com.win.mysql2xml.bean.PersonInfo;

/**
 * 
 * @author alanchan
 *
 */
public class PersonInfoItemProcessor implements ItemProcessor<PersonInfo, PersonInfo> {
    
    

	public PersonInfo process(PersonInfo personInfo) throws Exception {
    
    
		System.out.println("Processing result :" + personInfo);

		if (personInfo.getSalary() < 77) {
    
    

			PersonInfo tempPersonInfo = new PersonInfo();
			tempPersonInfo.setName(personInfo.getName());
			tempPersonInfo.setBirthday(personInfo.getBirthday());
			tempPersonInfo.setSalary(personInfo.getSalary() * 1.3);
			personInfo = tempPersonInfo;
		}

		return personInfo;
	}

}

6、添加Job listener(JobExecutionListener)

import java.util.List;

import org.joda.time.DateTime;
//import org.joda.time.DateTime;
import org.springframework.batch.core.BatchStatus;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobExecutionListener;

/**
 * 
 * @author alanchan
 *
 */
public class PersonInfoJobListener implements JobExecutionListener {
    
    

	private DateTime startTime, stopTime;

	public void beforeJob(JobExecution jobExecution) {
    
    
		startTime = new DateTime();
		System.out.println("job开始 at :" + startTime);
	}

	public void afterJob(JobExecution jobExecution) {
    
    
		stopTime = new DateTime();
		System.out.println("job结束 at :" + stopTime);
		System.out.println("任务耗时（毫秒） :" + getTimeInMillis(startTime, stopTime));

		if (jobExecution.getStatus() == BatchStatus.COMPLETED) {
    
    
			System.out.println("job任务完成");
			// Here you can perform some other business logic like cleanup
		} else if (jobExecution.getStatus() == BatchStatus.FAILED) {
    
    
			System.out.println("job任务异常如下 ");
			List<Throwable> exceptionList = jobExecution.getAllFailureExceptions();
			for (Throwable th : exceptionList) {
    
    
				System.err.println("异常 :" + th.getLocalizedMessage());
			}
		}
	}

	private long getTimeInMillis(DateTime start, DateTime stop) {
    
    
		return stop.getMillis() - start.getMillis();
	}

}

7、进行job的配置

1）、job配置

文件位置：/sping-batch/src/main/resources/spring-batch-context4.xml

        <batch:listeners>
            <batch:listener ref="jobListener" />
        </batch:listeners>
    </batch:job>

</beans>

2）、数据源配置

文件位置：/sping-batch/src/main/resources/context-datasource.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:batch="http://www.springframework.org/schema/batch" 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-4.0.xsd">

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://192.168.10.44:3306/test" />
        <property name="username" value="root" />
        <property name="password" value="1234" />
    </bean>

</beans>

8、创建一个运行job的main类

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

/**
 * 
 * @author alanchan
 *
 */
public class App {
    
    
	@SuppressWarnings("resource")
	public static void main(String areg[]) {
    
    

		ApplicationContext context = new ClassPathXmlApplicationContext("spring-batch-context4.xml");

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

		try {
    
    
			JobExecution execution = jobLauncher.run(job, new JobParameters());
			System.out.println("Job执行状态 : " + execution.getStatus());

		} catch (JobExecutionException e) {
    
    
			System.out.println("Job 执行失败");
			e.printStackTrace();
		}
	}
}

9、验证

运行程序 ，查看输出文件内以及控制台内容

1）、控制台输出

job开始 at :2023-07-21T10:49:44.683+08:00
Processing result :PersonInfo(name=alanchanchn, birthday=1985-02-01, salary=76.0)
Processing result :PersonInfo(name=alan, birthday=1979-09-01, salary=91.5)
Processing result :PersonInfo(name=chan, birthday=1993-03-01, salary=92.0)
Processing result :PersonInfo(name=alanchan, birthday=1995-08-01, salary=83.0)
job结束 at :2023-07-21T10:49:44.918+08:00
任务耗时（毫秒） :235
job任务完成
Job执行状态 : COMPLETED

2）、程序结果输出

二、示例2：从多数据源文件读取写入mysql

1、maven依赖

在这里插入代码片

2、创建表

DROP TABLE IF EXISTS `personinfo`;
CREATE TABLE `personinfo`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `salary` double(10, 2) NOT NULL,
  `birthday` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

3、PersonInfo bean

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import lombok.Data;

/**
 * @author alanchan
 *
 */
@Data
@Entity
@Table(name = "personinfo")
public class PersonInfo {
    
    
	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private int id;
	@Column(name = "name", nullable = false)
	private String name;
	@Column(name = "birthday", nullable = false)
	private String birthday;
	@Column(name = "salary", nullable = false)
	private double salary;
}

4、建立FieldSetMapper

import org.springframework.batch.item.file.mapping.FieldSetMapper;
import org.springframework.batch.item.file.transform.FieldSet;
import org.springframework.validation.BindException;

import com.win.multireaderhibernatewriter.bean.PersonInfo;

/**
 * 
 * @author alanchan
 *
 */
public class PersonInfoFieldSetMapper implements FieldSetMapper<PersonInfo> {
    
    

	public PersonInfo mapFieldSet(FieldSet fieldSet) throws BindException {
    
    
		PersonInfo personInfo = new PersonInfo();
		personInfo.setName(fieldSet.readString(0));
		personInfo.setBirthday(fieldSet.readString(1));
		personInfo.setSalary(fieldSet.readDouble(2));
		return personInfo;
	}

}

5、创建ItemProcessor实现类

import org.springframework.batch.item.ItemProcessor;

import com.win.multireaderhibernatewriter.bean.PersonInfo;

/**
 * 
 * @author alanchan
 *
 */
public class PersonInfoItemProcessor implements ItemProcessor<PersonInfo, PersonInfo> {
    
    

	public PersonInfo process(PersonInfo personInfo) throws Exception {
    
    
		System.out.println("Processing result :" + personInfo);

		if (personInfo.getSalary() < 60) {
    
    
			PersonInfo tempPersonInfo = new PersonInfo();
			tempPersonInfo.setName(personInfo.getName());
			tempPersonInfo.setBirthday(personInfo.getBirthday());
			tempPersonInfo.setSalary(personInfo.getSalary() * 1.5);
			personInfo = tempPersonInfo;
		}

		return personInfo;
	}
}

6、添加Job listener(JobExecutionListener)

import java.util.List;

import org.joda.time.DateTime;
import org.springframework.batch.core.BatchStatus;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobExecutionListener;

/**
 * 
 * @author chenw
 *
 */
public class PersonInfoJobListener implements JobExecutionListener {
    
    

	private DateTime startTime, stopTime;

	public void beforeJob(JobExecution jobExecution) {
    
    
		startTime = new DateTime();
		System.out.println("job开始 at :" + startTime);
	}

	public void afterJob(JobExecution jobExecution) {
    
    
		stopTime = new DateTime();
		System.out.println("job结束 at :" + stopTime);
		System.out.println("任务耗时（毫秒） :" + getTimeInMillis(startTime, stopTime));

		if (jobExecution.getStatus() == BatchStatus.COMPLETED) {
    
    
			System.out.println("job任务完成");
			// Here you can perform some other business logic like cleanup
		} else if (jobExecution.getStatus() == BatchStatus.FAILED) {
    
    
			System.out.println("job任务异常如下 ");
			List<Throwable> exceptionList = jobExecution.getAllFailureExceptions();
			for (Throwable th : exceptionList) {
    
    
				System.err.println("异常 :" + th.getLocalizedMessage());
			}
		}
	}

	private long getTimeInMillis(DateTime start, DateTime stop) {
    
    
		return stop.getMillis() - start.getMillis();
	}

}

7、进行job的配置

1）、数据源配置

	public static void main(String areg[]) {
    
    
		ApplicationContext context = new ClassPathXmlApplicationContext("spring-batch-context5.xml");

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

		try {
    
    
			JobExecution execution = jobLauncher.run(job, new JobParameters());
			System.out.println("Job 执行状态  : " + execution.getStatus());

		} catch (JobExecutionException e) {
    
    
			System.out.println("Job 失败");
			e.printStackTrace();
		}
	}
}

9、准备测试数据
