Springbatch3.0.1的xml架构？

Question

我正在尝试在春季3.0.1中完成弹簧批处理，并且类路径中已包含足够的jar。当我尝试使用命令行作业运行程序运行项目时，我得到了一个由于spring3.0.1的miss match xml架构而显示的错误。我有3个不同的xml文件，如下所示

的applicationContext.xml

Java代码：

public class HelloWorldTasklet implements Tasklet {
    private String message;

    public void setMessage(String message) {
        this.message = message;
    }

    @Override
    public RepeatStatus execute(StepContribution contribution,
            ChunkContext context) throws Exception {
        // TODO Auto-generated method stub
        System.out.println(message);
        return RepeatStatus.FINISHED;
    }
}

任何回复都会提前得到很高的评价。

Answer 1

您的类路径上有Spring Batch 2.2.0.RELEASE jar，但您没有在模式中指定该版本。更新以使用版本，你会没事的。

作为旁注，您是否有理由不在配置中使用模式？在配置批处理组件时，如果不使用命名空间或工厂bean，就会很难实现。例如，而不是：

<bean
    class="org.springframework.batch.core.repository.support.SimpleJobRepository"
    id="jobRepository">
    <constructor-arg>
        <bean
            class="org.springframework.batch.core.repository.dao.MapJobInstanceDao" />
    </constructor-arg>
    <constructor-arg>
        <bean
            class="org.springframework.batch.core.repository.dao.MapJobExecutionDao" />
    </constructor-arg>
    <constructor-arg>
        <bean
            class="org.springframework.batch.core.repository.dao.MapStepExecutionDao" />
    </constructor-arg>
    <constructor-arg>
        <bean
            class="org.springframework.batch.core.repository.dao.MapExecutionContextDao" />
    </constructor-arg>
</bean>

你可以这样做：

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="transactionManager" ref="transactionManager"/>
</bean>

我们还为作业配置提供名称空间支持。而不是：

<bean class="org.springframework.batch.core.job.SimpleJob" id="mySimpleJob">
    <property name="name" value="mySimpleJob" />
    <property name="steps">
        <list>
            <bean parent="taskletStep">
                <property name="tasklet" ref="helloTasklet" />
            </bean>
            <bean parent="taskletStep">
                <property name="tasklet" ref="createdByTasklet" />
            </bean>
        </list>
    </property>
    <property name="jobRepository" ref="jobRepository" />
</bean>

你应该试试这个：

<batch:job id="mySimpleJob">
    <batch:step id="step1" next="step2">
        <batch:tasklet ref="helloTasklet"/>
    </batch:step>
    <batch:step id="step2">
        <batch:tasklet ref="createdByTasklet"/>
    </batch:step>
</batch:job>

命名空间处理一些细节，例如自动连接作业存储库和事务管理器等。我建议您在这里查看Spring Batch文档：http://docs.spring.io/spring-batch/2.2.x/reference/html/index.html
