大家好，又见面了，我是你们的朋友全栈君。
Spring Batch示例中是读取本地文件sample-data.csv,然后存储到数据库people表中
https://github.com/spring-guides/gs-batch-processing
reader
@Bean
public FlatFileItemReader<People> reader() {
FlatFileItemReader<People> reader = new FlatFileItemReader<People>();
reader.setResource(new ClassPathResource("sample-data.csv"));
reader.setLineMapper(new DefaultLineMapper<People>() {
{
setLineTokenizer(new DelimitedLineTokenizer() {
{
setNames(new String[] { "firstName", "lastName" });
}
});
setFieldSetMapper(new BeanWrapperFieldSetMapper<People>() {
{
setTargetType(People.class);
}
});
}
});
return reader;
}我们新建一个db_reader用以读取数据库表中的内容，然后经过processor，重新更新到数据库中。
@Bean(destroyMethod="")
public ItemReader<? extends User> db_reader() {
JpaPagingItemReader<User> reader = new JpaPagingItemReader<User>();
String sqlQuery = "select id,username,updatetime from test.user where id = :limit ";
try {
JpaNativeQueryProvider<User> queryProvider = new JpaNativeQueryProvider<User>();
queryProvider.setSqlQuery(sqlQuery);
queryProvider.setEntityClass(User.class);
queryProvider.afterPropertiesSet();
reader.setEntityManagerFactory(emf);
reader.setPageSize(3);
reader.setQueryProvider(queryProvider);
reader.setParameterValues(Collections.<String, Object>singletonMap("limit", 1));
reader.afterPropertiesSet();
reader.setSaveState(true);
} catch (Exception e) {
e.printStackTrace();
}
return reader;
}
新建一个step
@Bean
public Step step1() {
return stepBuilderFactory
.get("step1")
.<User, People>chunk(10)
.reader(db_reader())
.processor(db_processor())
.writer(writer())
.build();
}Job中加入新增的Step
@Bean
public Job importUserJob(JobCompletionNotificationListener listener) {
return jobBuilderFactory
.get("importUserJob")
.incrementer(new RunIdIncrementer())
.listener(listener)
.flow(step1())
.next(step0())
.end()
.build();
}
运行效果
