如何使用批注在Spring Batch中运行多个作业

我正在使用Spring Boot + Spring Batch（注释），遇到了必须运行2个作业的场景。

我有员工和薪水记录，需要使用春季批处理进行更新。我已经BatchConiguration按照本教程的spring-batch Employee和Salary对象入门教程（分别名为BatchConfigurationEmployee和BatchConfigurationSalary）配置了类。

我已经定义了ItemReader，ItemProcessor，ItemWriter并Job按照这上面已经提到的教程。

当我启动Spring Boot应用程序时，将运行两个Job之一，我想同时运行两个BatchConfigured类。我该如何实现

********* BatchConfigurationEmployee.java *************

@Configuration
@EnableBatchProcessing
public class BatchConfigurationEmployee {
    public ItemReader<employee> reader() {
        return new EmployeeItemReader();
    }

    @Bean
    public ItemProcessor<Employee, Employee> processor() {
        return new EmployeeItemProcessor();
    }

    @Bean   
    public Job Employee(JobBuilderFactory jobs, Step s1) {
        return jobs.get("Employee")
                .incrementer(new RunIdIncrementer())
                .flow(s1)
                .end()
                .build();
    }

    @Bean
    public Step step1(StepBuilderFactory stepBuilderFactory, ItemReader<Employee> reader,
                    ItemProcessor<Employee, Employee> processor) {
        return stepBuilderFactory.get("step1")
                .<Employee, Employee> chunk(1)
                .reader(reader)
                .processor(processor)
                .build();
    }
}

工资班在这里

@Configuration
@EnableBatchProcessing
public class BatchConfigurationSalary {
    public ItemReader<Salary> reader() {
        return new SalaryItemReader();
    }

    @Bean
    public ItemProcessor<Salary, Salary> processor() {
        return new SalaryItemProcessor();
    }

    @Bean
    public Job salary(JobBuilderFactory jobs, Step s1) {
        return jobs.get("Salary")
                .incrementer(new RunIdIncrementer())
                .flow(s1)
                .end()
                .build();
    }

    @Bean
    public Step step1(StepBuilderFactory stepBuilderFactory, ItemReader<Salary> reader,
                    ItemProcessor<Salary, Salary> processor) {
        return stepBuilderFactory.get("step1")
                .<Salary, Salary> chunk(1)
                .reader(reader)
                .processor(processor)
                .build();
    }
}
