具有文件名的java Spring批处理作业参数

我想用SpringBatch rest控制器和动态输入文件名创建项目

我的代码：Rest控制器

@RestController

公共类FileNameController{

@Autowired
JobLauncher jobLauncher;

@Autowired
Job job;

@RequestMapping("/launchjob")
public String handle(@RequestParam("fileName") String fileName) throws Exception {

    Logger logger = LoggerFactory.getLogger(this.getClass());
    try {
        JobParameters jobParameters = new JobParametersBuilder()
                                                    .addString("input.file.name", fileName)
                                                    .addLong("time", System.currentTimeMillis())
                                                    .toJobParameters();
        jobLauncher.run(job, jobParameters);
    } catch (Exception e) {
        logger.info(e.getMessage());
    }

    return "Done";
}

}

作业配置：

@Configuration

@EnableBatchProcessing 公共类JobConfig{

@Autowired
public JobBuilderFactory jobBuilderFactory;

@Autowired
public StepBuilderFactory stepBuilderFactory;


 Filetasklet ft=new Filetasklet();
 Logger log = LoggerFactory.getLogger(this.getClass().getName());


private String pathFile = urlCoffreFort + "\\" + ft.getFileName();

// => Configuration of Job  
        @Bean
        public Job job() throws IOException {
                    return jobBuilderFactory.get("job")
                    .incrementer(new RunIdIncrementer())
                    .flow(step1())
                    .end()
                    .build();
        }

        //###### Steps          
        // => Step cecStep1
        @Bean
        public Step step1() throws IOException {
            return stepBuilderFactory.get("fileDecrypt")
                    .<Person, String>chunk(100)
                    .reader(reader1())
                    .processor(processor1FileDecrypt())
                    .writer(writer1())
                    .faultTolerant()
                    .skip(Exception.class)
                    .skipLimit(100)
                    .build();
        }
        // ####### readers 

        // => reader1()
        @Bean
        public FlatFileItemReader<Person> reader1() throws IOException{

            return new FlatFileItemReaderBuilder<CSCivique>().name("personItemReader")
                                        .resource(new ClassPathResource(pathFile))
                                        .delimited()
                                        .delimiter(";")
                                        .names(new String[] { "id",  "nomNaissance", "prenom" })
                                        .targetType(CSCivique.class)
                                        .build();
        }

        // ######Processors             

        @Bean
        public PersonItemProcessor1FileDecrypt processor1FileDecrypt() {
            return new PersonItemProcessor1FileDecrypt();
        }

        // ######Writers 

        @Bean
        public FlatFileItemWriter<String> writer1() {
            return new FlatFileItemWriterBuilder<String>().name("greetingItemWriter")
                    .resource(new FileSystemResource("sav/greetings.csv"))
                    .lineAggregator(new PassThroughLineAggregator<>()).build();
        }

}

当我编写url时： http://localhost:8080/launchjob?fileName=djecc5cpt.csv 控制台打印：

PreparedStatementCallback；错误的SQL语法[从批处理作业实例中选择作业实例ID、作业名称，其中作业名称=？和作业密钥=？]；嵌套的异常是org。postgresql。util。PSQLException:错误：“批处理作业实例”关系不存在职位：39

有 Java 编程相关的问题?
