我是Spring和Spring Batch的新手我正在为Spring Batch作业设置Java配置，我使用正确运行的XML配置测试了它 . 但是我遇到了一个问题，我甚至无法让应用程序运行，因为我相信，设置DataSource bean会出现问题 . 我要解决这里抛出的错误：
2016 - 11 - 22 16: 49: 59.819 WARN 20056---[main] o.s.c.a.ConfigurationClassEnhancer: @Bean method ScopeConfiguration.stepScope is non - static and returns an object assignable to Spring's BeanFactoryPostProcessor interface. This will result in a failure to process annotations such as @Autowired, @Resource and @PostConstruct within the method's declaring@ Configuration class.Add the 'static' modifier to this method to avoid these container lifecycle issues; see@ Bean javadoc for complete details.

我不知道我的配置出错了，因为我遵循了Spring和其他教程提出的设计模式 . 由于bean未正确创建且工厂后处理未关闭，因此会破坏我在ArchiveJobConfig类中设置的Autowired cBeans . 任何帮助，将不胜感激

Job Launcher
这个类将从一个控制器调用，以启动一个参数列表，我将在另一个类中映射到所需的参数列表，但尚未实现 . 该参数仅用于连接到数据库后的测试 .
@ComponentScan
@EnableAutoConfiguration
public class ArchiveJob {
public int startJob(List paramList) throws JobParametersInvalidException, JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException, BeansException {
SpringApplication app = new SpringApplication(ArchiveJob.class);
ConfigurableApplicationContext ctx = app.run();
BatchStatus exitStatus;
String test = "2016";
SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
Job archiveDBJob = ctx.getBean("archiveDBJob", Job.class);
JobParameters jobParameters = new JobParametersBuilder()
.addString("year", test)
.toJobParameters();
JobExecution jobExecution = jobLauncher.run(archiveDBJob, jobParameters);
exitStatus = jobExecution.getStatus();
if(exitStatus.equals("COMPLETED"))
return 1;
else
return 0;
}
}
ArchiveJobConfig
这是作业持有占位符项读取器，编写器和Spring Batch java配置服务示例中的处理器 . 插入这些只是为了验证我的读者，作家等不会导致问题 .
@Configuration
@EnableBatchProcessing
@Import( InfrastructureConfig.class )
public class ArchiveJobConfig {
@Autowired
public JobBuilderFactory jobBuilderFactory;
@Autowired
public StepBuilderFactory stepBuilderFactory;
@Autowired
public DataSource dataSource;
@Bean
public ItemReader<Person> reader() {
FlatFileItemReader<Person> reader = new FlatFileItemReader<Person>();
reader.setResource(new ClassPathResource("sample-data.csv"));
reader.setLineMapper(new DefaultLineMapper<Person>() {{
setLineTokenizer(new DelimitedLineTokenizer() {{
setNames(new String[] { "firstName", "lastName" });
}});
setFieldSetMapper(new BeanWrapperFieldSetMapper<Person>() {{
setTargetType(Person.class);
}});
}});
return reader;
}
@Bean
public PersonItemProcessor processor() {
return new PersonItemProcessor();
}
@Bean
public ItemWriter<Person> writer() {
JdbcBatchItemWriter<Person> writer = new JdbcBatchItemWriter<Person>();
writer.setItemSqlParameterSourceProvider(new BeanPropertyItemSqlParameterSourceProvider<Person>());
writer.setSql("INSERT INTO people (first_name, last_name) VALUES (:firstName, :lastName)");
writer.setDataSource(dataSource);
return writer;
}
@Bean
public Job archiveDBJob() {
return jobBuilderFactory.get("archiveDBJob")
.incrementer(new RunIdIncrementer())
.flow(step1())
.end()
.build();
}
@Bean
public Step step1() {
return stepBuilderFactory.get("step")
.<Person,Person>chunk(10)
.reader(reader())
.processor(processor())
.writer(writer())
.build();
}
}
Infrastructure Class - DataSource Bean
这是我认为问题正在发生的地方，url和驱动程序设置器中的值是此提交的占位符 . 我将此类导入到作业配置类中 . 使用EnableBatchProcessing注释，应该自动创建jobRepository bean，并且自动装配bean应该使我设置的数据源成为此作业的默认数据源 . 但我很遗憾地错过了配置中的一些步骤 . 再次任何建议/协助将不胜感激
@Configuration
@PropertySource("classpath:spring/batch/config/db.properties")
public class InfrastructureConfig {
@Autowired
Environment env;
@Bean
public DataSource dataSource() {
return DataSourceBuilder.create()
// .driverClassName(env.getProperty("databaseUrl"))
// .url(env.getProperty("databaseUrl"))
.driverClassName("com.mysql.jdbc.Driver")
.url("databaseUrl")
.build();
}
