Question

我正在尝试使用Spring Batchs在MySQL数据库中运行详细信息，我进行了一些调试，但我似乎无法通过@EnableBatchProcessing错误...

我彻底搜索了可能是我的错误以及我做错了什么但无济于事...我认为可能是问题出在依赖错误上？但是我尝试安装不同的版本/依赖项，但这会带来更多错误...请向T.T咨询

这是我显示的完整控制台错误...

这是我的DemoApplication ...

package com.example.demo;

import org.springframework.boot.SpringApplication;

import java.util.logging.Logger;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {

        logger.info("starting project...");

        SpringApplication.run(DemoApplication.class, args);

        logger.info("done processing");


    }
}

我的SpringBatchConfiguration类...

    @Configuration

public class SpringBatchConfig {

    @Autowired
    public JobBuilderFactory jobBuilderFactory;

    @Autowired

Answer 1

您需要定义JobBuilderFactory bean

@Bean
public JobBuilderFactory jobBuilderFactory() throws Exception {
    JobBuilderFactory jobBuilderFactory = new JobBuilderFactory(jobRepository());
    return jobBuilderFactory;
}

Answer 2

java.lang.ClassNotFoundException: javax.batch.runtime.JobInstance意味着您遇到了依赖项解析问题，并且JSR-352 jar不在您的类路径中。我建议使用spring-boot-starter-batch并让spring boot管理依赖项，而不是手动导入spring-batch-core和spring-batch-infrastrucutre并将其版本设置为4.1.0。

您需要：

删除spring-batch-core和spring-batch-infrastrucutre并用spring-boot-starter-batch替换（不指定版本，Spring Boot将导入正确的版本）
在SpringBatchConfig中，自动装配数据源，并将其同时定义为bean。虽然这不是问题，但我不明白为什么需要在此类中自动装配数据源，因此您可以尝试删除@Autowired public DataSource dataSource;并将@Bean public static DataSource dataSource()设为 non 静态的。

希望这会有所帮助。

Answer 3

在主应用程序类“DemoApplication”上添加@EnableBatchProcessing

@SpringBootApplication
@EnableBatchProcessing
public class DemoApplication {

    public static void main(String[] args) {
        Logger logger = Logger.getLogger("SpringBatchConfig.java");

    logger.info("starting project...");
.
.
.
}
}

@EnableBatchProcessing上的不满意依赖项异常
