Spring批处理--没有找到产品名称的DatabaseType：[]

Question

我想用Spring引导来实现Spring，因为我们使用的是informix数据库，所以当我的spring引导应用程序启动时，我会遇到以下异常。

配置：

@Bean
public DataSource dataSource() throws SQLException {
   BasicDataSource dataSource = new BasicDataSource();
   dataSource.setDriverClassName(dataSourceProperties.getDriverClassName());
    dataSource.setUrl(dataSourceProperties.getDbUrl());
    dataSource.setUsername(dataSourceProperties.getDbUsername());
    dataSource.setPassword(dataSourceProperties.getDbPassword())
    return dataSource;
}


@Bean
public DataSourceTransactionManager dataSourceTransactionManager(DataSource dataSource){

    DataSourceTransactionManager manager=new DataSourceTransactionManager(dataSource);
    return manager;
}

@Bean
public JobRepositoryFactoryBean jobRepositoryFactoryBean( DataSourceTransactionManager txManager,DataSource dataSource ) throws Exception{

    JobRepositoryFactoryBean job=new JobRepositoryFactoryBean();
    job.setDataSource(dataSource);
    job.setDatabaseType("oracle");
    job.setTransactionManager(txManager);
    job.afterPropertiesSet();
    return job;
}


@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 ItemProcessor<Person, Person> processor() {
    return new PersonItemProcessor();
}

@Bean
public ItemWriter<Person> writer(DataSource dataSource) {
    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);
    writer.afterPropertiesSet();
    return writer;
}

@Bean
public Job importUserJob(JobBuilderFactory jobs, Step s1, JobExecutionListener listener,JobRepositoryFactoryBean jobRepositoryFactoryBean) throws Exception {


    return jobs.get("importUserJob")
             .repository(jobRepositoryFactoryBean.getObject())
            .incrementer(new RunIdIncrementer())
            .listener(listener)
            .flow(s1)
            .end()
            .build();
}

@Bean
public Step step1(StepBuilderFactory stepBuilderFactory, ItemReader<Person> reader,
        ItemWriter<Person> writer, ItemProcessor<Person, Person> processor) {
    return stepBuilderFactory.get("step1")
            .<Person, Person> chunk(10)
            .reader(reader)
            .processor(processor)
            .writer(writer)
            .build();
}

异常

Spring批处理似乎不直接支持Informix。

来自org.springframework.batch.support.DatabaseType：

DERBY("Apache Derby"), 
DB2("DB2"), 
DB2ZOS("DB2ZOS"), 
HSQL("HSQL Database Engine"),
SQLSERVER("Microsoft SQL Server"),
MYSQL("MySQL"),
ORACLE("Oracle"),
POSTGRES("PostgreSQL"),
SYBASE("Sybase"), H2("H2");

但是，正如这里所说的：http://forum.spring.io/forum/spring-projects/batch/61097-why-spring-batch-doesn-t-support-informix-database，您似乎可以将数据库类型设置为Oracle，并且它将支持Informix。
