如何拥有多个 spring 启动批处理配置 class

Question

如果我想在我的批处理项目中有多个作业。每个文件只包含一个作业。

作业 1：

@Configuration
public class StartTest1 {

    @Autowired
    JobBuilderFactory jobBuilderFactory;

    @Autowired
    StepBuilderFactory stepBuilderFactory;

    @Bean
    public Job processJob() {
        return jobBuilderFactory.get("processJob1").incrementer(new RunIdIncrementer())....;
    }
    ....
}

作业 2：

@Configuration
public class StartTest2 {

    @Autowired
    JobBuilderFactory jobBuilderFactory;

    @Autowired
    StepBuilderFactory stepBuilderFactory;

    @Bean
    public Job processJob() {
        return jobBuilderFactory.get("processJob2").incrementer(new RunIdIncrementer())....;
    }
    ....
}

我尝试为每个 class 设置 @Configuration 注释。但是只有一项工作在运行时间执行。如何拥有多个作业文件？

Answer 1

我认为问题在于两个作业 bean 具有相同的名称 processJob，因此在构建应用程序上下文时一个会覆盖另一个。最简单的解决方案是使用唯一的 bean 名称，例如您为 Job 提供的名称：processJob1、processJob2.

Answer 2

我找到了另一种方法，

set different bean name!

工作 1：

@Configuration
public class StartTest1 {

    @Autowired
    JobBuilderFactory jobBuilderFactory;

    @Autowired
    StepBuilderFactory stepBuilderFactory;

    @Bean("job1")
    public Job processJob() {
        return jobBuilderFactory.get("processJob1").incrementer(new RunIdIncrementer())....;
    }
    ....
}

作业 2：

@Configuration
public class StartTest2 {

    @Autowired
    JobBuilderFactory jobBuilderFactory;

    @Autowired
    StepBuilderFactory stepBuilderFactory;

    @Bean("job2")
    public Job processJob() {
        return jobBuilderFactory.get("processJob2").incrementer(new RunIdIncrementer())....;
    }
    ....
}
