spring batch配置db2的DataSourceConfig示例代码

以下是一个使用Spring Batch的DB2数据源配置示例代码：

@Configuration
@EnableBatchProcessing
public class BatchConfig {

    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Autowired
    private DataSource dataSource;

    @Bean
    public JdbcCursorItemReader<YourEntity> reader() {
        JdbcCursorItemReader<YourEntity> reader = new JdbcCursorItemReader<>();
        reader.setDataSource(dataSource);
        reader.setSql("SELECT * FROM YOUR_TABLE");
        reader.setRowMapper(new YourEntityRowMapper());
        return reader;
    }

    @Bean
    public ItemProcessor<YourEntity, YourProcessedEntity> processor() {
        return new YourEntityProcessor();
    }

    @Bean
    public JdbcBatchItemWriter<YourProcessedEntity> writer() {
        JdbcBatchItemWriter<YourProcessedEntity> writer = new JdbcBatchItemWriter<>();
        writer.setDataSource(dataSource);
        writer.setSql("INSERT INTO YOUR_TABLE_PROCESSED VALUES (:id, :name)");
        writer.setItemSqlParameterSourceProvider(new BeanPropertyItemSqlParameterSourceProvider<>());
        writer.afterPropertiesSet();
        return writer;
    }

    @Bean
    public Step step1() {
        return stepBuilderFactory.get("step1")
                .<YourEntity, YourProcessedEntity>chunk(10)
                .reader(reader())
                .processor(processor())
                .writer(writer())
                .build();
    }

    @Bean
    public Job job() {
        return jobBuilderFactory.get("job")
                .incrementer(new RunIdIncrementer())
                .start(step1())
                .build();
    }

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.ibm.db2.jcc.DB2Driver");
        dataSource.setUrl("jdbc:db2://your-db2-server:your-db2-port/your-db2-database");
        dataSource.setUsername("your-db2-username");
        dataSource.setPassword("your-db2-password");
        return dataSource;
    }

}

请注意，这里的数据源是使用`DriverManagerDataSource`配置的。您可以使用其他类型的数据源，例如`BasicDataSource`或`HikariDataSource`。只需根据您的需要进行修改即可。
