最近接触springbatch处理一些批量的业务数据，由于公司项目是SpringMvc架构，网上大部分SpringBatch都是和SpringBoot搭配使用的，在爬无数个坑后，记录下SpringMvc和SpringBatch搭配方式（ps：注解方式）。
前提是您已然熟悉使用SpringMVC和SpringBatch。
1、创建纯粹的SpringMvc项目
我用的是intellij，项目结构如图

public class TestController {

public String hello(){
return "Hello world.";
}
}
好啦，如果启动tomcat，看到如下页面，说明一个纯粹的SpringMvc项目已经搭建好了

2、下面开始一步一步加入SpringBatch
修改后的项目结构
下面备注的是需要添加的部分
修改pom.xml，加入SpringBatch依赖

添加数据库配置文件，用于存储springbatch任务执行情况
custom.jdbc.connection.driverClass=com.mysql.jdbc.Driver
custom.jdbc.connection.jdbcUrl=jdbc:mysql://127.0.0.1:3306/xxxx?useUnicossssde=true&characterEncoding=UTF-8&allowMultiQueries=true
custom.jdbc.connection.user=xxxx
custom.jdbc.connection.password=xxxx
修改dispatcher-servlet.xml，添加数据源和对springmvc定时任务的支持
text/html;charset=UTF-8
添加SpringBatchJob，我们只简单打印一句话标明SpringBatch运行了；由于SpringBatchJob在咱们配置的SpringMvc扫描包内，所以不用再去声明bean了，SpringMvc会扫描到自动注入的。
package com.test;
import org.springframework.batch.core.*;
import org.springframework.batch.core.annotation.AfterJob;
import org.springframework.batch.core.annotation.BeforeJob;
import org.springframework.batch.core.configuration.annotation.EnableBatchProcessing;
import org.springframework.batch.core.configuration.annotation.JobBuilderFactory;
import org.springframework.batch.core.configuration.annotation.StepBuilderFactory;
import org.springframework.batch.repeat.RepeatStatus;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.Map;
@Configuration
@EnableBatchProcessing
public class SpringBatchJob {
@Autowired
JobBuilderFactory jobBuilderFactory;
@Autowired
StepBuilderFactory stepBuilderFactory;
@Bean
@Qualifier("batchJob")
public Job batchJob() {
return jobBuilderFactory.get(System.currentTimeMillis() + "")
.start(step())
.build();
}
@Autowired
public Step step() {
return stepBuilderFactory.get("step")
.tasklet((stepContribution, chunkContext) -> {
System.out.println("########################## I am SpringBatch! ##########################");
return RepeatStatus.FINISHED;
})
.build();
}
}
添加springMvc定时任务
package com.test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.JobParametersBuilder;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.util.Date;
@Component
public class QuartzTask {
final static Logger logger = LoggerFactory.getLogger(QuartzTask.class);
@Autowired
JobLauncher jobLauncher;
@Autowired
Job batchJob;
/**
* 定时计算。每分触发
*/
@Scheduled(cron = "0/5 * * * * ?")
public void run() {
try {
//由于注入bean后，每次调用都是同一个springbatch job实例，且springbatch默认任务是不重复执行的，所以需要每次传递不同参数来每次都执行Springbatch
//如果有中文参数，需要将springbatch相关表，字符编码改为utf-8，且表中字段字符编码也改为utf-8，不然记录springbatch参数到数据库会报错，导致任务一直无法执行
JobParameters params = new JobParametersBuilder().addDate("timestamp",new Date()).toJobParameters();
jobLauncher.run(batchJob, params);
logger.info("job run ... ");
} catch (Exception e) {
}
}
}
好啦，这时再启动tomcat后，到了任务执行时间就会在控制台输出啦
