Question

我正在eclipse中使用Spring Batch开发一个应用程序

启动服务器时出错

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: 
 Error creating bean with name 'notificationController' defined in ServletContext       
 resource [/WEB-INF/springbatch-config.xml]: Cannot create inner bean 
 'com.confluence14.utility.Notifier#72372ef8' of type 
 [com.confluence14.utility.Notifier] while setting constructor argument; 
 nested exception is org.springframework.beans.factory.BeanCreationException: 
 Error creating bean with name 'com.confluence14.utility.Notifier#72372ef8' defined in

 'dispatchMailsJob': Cannot create inner bean '(inner bean)' of type 
 [org.springframework.batch.core.configuration.xml.SimpleFlowFactoryBean] while setting 
 bean property 'flow'; ......and so on.......

我用于配置spring批处理的xml文件是

<?xml version="1.0" encoding="UTF-8"?>

            </bean>
        </constructor-arg>
    </bean>
</beans>

现在问题在于此配置文件顶部的xmlns部分。

在这个配置文件中，我声明的最后一个bean notificationController尝试引用名为dispatchMailsJob的bean，它是上面声明的第一个bean但无法识别它。

我被打了好几天。这是我在春季批次的第二个项目，我记得同样的问题在我的第一个项目中消耗了几天。（我现在无法访问我的第一个项目的代码）

请帮我解决一下我应该在xmlns架构部分写什么

我使用的弹簧相关库是

spring-aop-3.2.3.RELEASE.jar
spring-batch-core-2.2.3.RELEASE.jar
spring-batch-infrastructure-2.2.3.RELEASE.jar
spring-beans-3.2.3.RELEASE.jar

Answer 1

对于使用后期绑定（例如scope="step"）的bean，可能需要#{jobParameters[...]}; spring无法创建作业bean，因为它无法解析与批处理相关的spEL表达式
