Spring Batch Java Config事务 - 属性等价 [英] Spring Batch Java Config transaction-attributes equivalent

问题描述

在Spring批处理中，您可以设置事务隔离和传播，如下所示：

In Spring batch you can set the transaction isolation and propagation like this:

<job id="someJob" xmlns="http://www.springframework.org/schema/batch">
   <step id="readWriteDate">
      <tasklet transaction-manager="transactionManager">
         <transaction-attributes isolation="DEFAULT" propagation="REQUIRED" timeout="30"/>
         <chunk reader="dbItemReader" processor="dbItemProcessor" writer="dbItemWriter"
                commit-interval="2" />
      </tasklet>
   </step>
</job>

我找不到相同的java配置。

I cant find the java config equivalent.

推荐答案

好吧它就在那里

@Configuration
public class StepWithTx {

    @Autowired
    private StepBuilderFactory steps;

    @Bean
    public Step step() throws Exception {
        return steps
                .get("CustomTxStep")
                .<String, String>chunk(10)
                .transactionAttribute(transactionAttribute...)
                .reader(reader...)
                .processor(processor...)
                .writer(writer...)
                .build();
    }
}

默认实现看看 http：// docs .spring.io / spring / docs / 4.0.5.RELEASE / javadoc-api / org / springframework / transaction / interceptor / package-summary.html
