Spring Boot - 批处理服务

批处理服务是一个在单个任务中执行多个命令的过程。在本章中，您将学习如何在 Spring Boot 应用程序中创建批处理服务。

让我们考虑一个将 CSV 文件内容保存到 MySql 的示例。

要创建批处理服务程序，我们需要在构建配置文件中添加 Spring Boot Starter Batch、MySQL 和 Spring Data JPA 依赖项。

Maven 用户可以在 pom.xml 文件中添加以下依赖项。

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-batch</artifactId>
</dependency>
<dependency>
   <groupId>com.mysql</groupId>
   <artifactId>mysql-connector-j</artifactId>
</dependency>
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

Gradle 用户可以在 build.gradle 文件中添加以下依赖项。

compile("org.springframework.boot:spring-boot-starter-batch")
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile("com.mysql:mysql-connector-j")

现在，将简单的 CSV 数据文件添加到类路径资源 - src/main/resources 下，并将文件命名为 report.csv，如下所示 -

report.csv

William,John
Mike, Sebastian
Lawarance, Lime
Kumar, Mahesh
Goswami, Saikat
Khan, Jaid
Kaur, Manpreet

为 USERS 模型创建一个 POJO 类，如下所示 -

User.java

package com.tutorialspoint.batchservice.model;

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.Id;

@Entity
public class User {
	   
   @Id
   @GeneratedValue
   private Long id;

   private String lastName;
   private String firstName;

   public User() {
   }
   public User(String firstName, String lastName) {
      this.firstName = firstName;
      this.lastName = lastName;
   }
   public void setFirstName(String firstName) {
      this.firstName = firstName;
   }
   public String getFirstName() {
      return firstName;
   }
   public String getLastName() {
      return lastName;
   }
   public void setLastName(String lastName) {
      this.lastName = lastName;
   }

   @Override
   public String toString() {
      return "firstName: " + firstName + ", lastName: " + lastName;
   }   
}

现在，创建一个中间处理器，在从 CSV 文件读取数据和将数据写入 SQL 之前执行操作。

UserItemProcessor.java

package com.tutorialspoint.batchservice.processor;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.batch.item.ItemProcessor;

import com.tutorialspoint.batchservice.model.User;

public class UserItemProcessor implements ItemProcessor<User, User> {
   private static final Logger log = LoggerFactory.getLogger(UserItemProcessor.class);

   @Override
   public User process(final User user) throws Exception {
      final String firstName = user.getFirstName().toUpperCase();
      final String lastName = user.getLastName().toUpperCase();
      final User transformedPerson = new User(firstName, lastName);

      log.info("Converting (" + user + ") into (" + transformedPerson + ")");
      return transformedPerson;
   }
}

让我们创建一个批处理配置文件，用于读取 CSV 中的数据并将其写入数据库，如下所示。

BatchConfiguration.java

package com.tutorialspoint.batchservice.configuration;

import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobExecutionListener;
import org.springframework.batch.core.Step;
import org.springframework.batch.core.configuration.annotation.StepScope;
import org.springframework.batch.core.job.builder.JobBuilder;
import org.springframework.batch.core.launch.support.RunIdIncrementer;
import org.springframework.batch.core.repository.JobRepository;
import org.springframework.batch.core.step.builder.StepBuilder;
import org.springframework.batch.item.ItemWriter;
import org.springframework.batch.item.file.FlatFileItemReader;
import org.springframework.batch.item.file.mapping.BeanWrapperFieldSetMapper;
import org.springframework.batch.item.file.mapping.DefaultLineMapper;
import org.springframework.batch.item.file.transform.DelimitedLineTokenizer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.transaction.PlatformTransactionManager;

import com.tutorialspoint.batchservice.listener.UserListener;
import com.tutorialspoint.batchservice.model.User;
import com.tutorialspoint.batchservice.processor.UserItemProcessor;
import com.tutorialspoint.batchservice.repository.UserRepository;

@Configuration
public class BatchConfiguration {

   @Bean
   FlatFileItemReader<User> reader() {

      FlatFileItemReader<User> reader= new FlatFileItemReader<>();
      reader.setResource(new ClassPathResource("/report.csv"));

      reader.setLineMapper(new DefaultLineMapper<>() {{
         setLineTokenizer(new DelimitedLineTokenizer() {{
            setDelimiter(DELIMITER_COMMA);
            setNames("lastName","firstName");
         }});

         setFieldSetMapper(new BeanWrapperFieldSetMapper<>() {{
            setTargetType(User.class);
         }});
      }});
      return reader;
   }

   @Autowired
   UserRepository repository;

   @Bean
   ItemWriter<User> writer(){
      return users -> {
         System.out.println("Saving User: " +users);
         repository.saveAll(users);
      };
   }

   @Bean
   public JobExecutionListener listener() {
      return new UserListener();
   }

   @Bean
   Job importUserJob(JobRepository jobRepository, Step step1) {
      return new JobBuilder("importUserJob", jobRepository)
         .incrementer(new RunIdIncrementer())
         .listener(listener())
         .start(step1)
         .build();
   }

   @Bean
   Step step1(JobRepository jobRepository, PlatformTransactionManager transactionManager) {
      return new StepBuilder("step1", jobRepository)
         .<User, User>chunk(100, transactionManager)
         .reader(reader())
         .processor(userProcessor())
         .writer(writer())
         .build();
   }

   @Bean
   @StepScope
   UserItemProcessor userProcessor() {
      return new UserItemProcessor();
   } 
}

reader() 方法用于从 CSV 文件读取数据，而 writer() 方法用于将数据写入数据库。

接下来，我们将不得不编写一个作业完成通知监听器类 - 用于在作业完成之后发出通知。

UserListener.java

package com.tutorialspoint.batchservice.listener;

import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobExecutionListener;

public class UserListener implements JobExecutionListener{

   @Override
   public void beforeJob(JobExecution jobExecution) {
      System.out.println("Job Started: "+ jobExecution.getStartTime() 
         + ", Status: " + jobExecution.getStatus());
   }

   @Override
   public void afterJob(JobExecution jobExecution) {
      System.out.println("Job Started: "+ jobExecution.getStartTime() 
         + ", Status: " + jobExecution.getStatus());
   }
}

我们将不得不编写一个存储库，它将用户保存到数据库中。

UserRepository.java

package com.tutorialspoint.batchservice.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import com.tutorialspoint.batchservice.model.User;

public interface UserRepository extends JpaRepository<User, Long> {
}

我们有自定义处理器来显示保存到数据库之前记录的自定义。

UserItemProcessor.java

package com.tutorialspoint.batchservice.processor;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.batch.item.ItemProcessor;

import com.tutorialspoint.batchservice.model.User;

public class UserItemProcessor implements ItemProcessor<User, User> {
   private static final Logger log = LoggerFactory.getLogger(UserItemProcessor.class);

   @Override
   public User process(final User user) throws Exception {
      final String firstName = user.getFirstName().toUpperCase();
      final String lastName = user.getLastName().toUpperCase();
      final User transformedPerson = new User(firstName, lastName);

      log.info("Converting (" + user + ") into (" + transformedPerson + ")");
      return transformedPerson;
   }
}

主要的 Spring Boot 应用程序类。

BatchserviceApplication.java

package com.tutorialspoint.batchservice;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication()
public class BatchserviceApplication {

   public static void main(String[] args) {
      SpringApplication.run(BatchserviceApplication.class, args);
   }
}

这是完整的 pom.xml

编译和执行

现在，创建一个可执行的 JAR 文件，并使用以下 Maven 或 Gradle 命令运行 Spring Boot 应用程序。

对于 Maven，使用如下所示的命令 -

mvn clean install

在“BUILD SUCCESS”之后，您可以在 target 目录下找到 JAR 文件。

对于 Gradle，您可以使用如下所示的命令 -

gradle clean build

在“BUILD SUCCESSFUL”之后，您可以在 build/libs 目录下找到 JAR 文件。

使用此处提供的命令运行 JAR 文件 -

java –jar <JARFILE>

您可以在控制台窗口中看到输出，如下所示 -
