Spring 批处理管理 (2.0.0.M1)：创建 bean batchMBeanExporter 时出错

Question

我正尝试从 spring 启动应用程序运行 spring 批管理。

我正在使用来自 Michael (@mminella) 的 this 优秀示例。此应用程序运行良好。

但是，我需要使用maven的类似应用程序；我继续使用相同的文件、作业、配置和依赖项创建了一个。但我最终出现了以下异常。

我看到的唯一区别是 spring-batch-core 的版本。对于 Maven，它的版本是 3.0.6，而对于 gradle（Michael 的应用程序），它的版本是 3.0.4.

不确定我使用 maven 时发生了什么；非常感谢您的帮助。如果需要任何其他详细信息，请告诉我。

期待您的意见。

谢谢，

Spring 启动配置

@SpringBootApplication(exclude = {HypermediaAutoConfiguration.class, MultipartAutoConfiguration.class})
@EnableBatchAdmin
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

Answer 1

最后，我能够使用 spring 批处理管理员运行 spring 批处理；尽管有 this 个项目。仍然无法将 @EnableBatchAdmin 与 Maven 构建一起使用。非常感谢 mminella 和@vesperaba。

虽然我面临另一个问题；当我运行来自存储库的带有 2.0.0.M1 的项目时，它工作正常。但是，当我在解决 [JobController 空指针异常] (https://github.com/spring-projects/spring-batch-admin/pull/42) 后在本地构建项目时；

我必须明确地在 POM 中包含 "spring-batch-admin-resources"；当我运行应用程序使用时情况并非如此存储库 (libs-snapshot-local) 2.0.0.M1 建造。
当我包含 "spring-batch-admin-resources" 应用程序时不能够开始说“cvc-datatype-valid.1.2.1： '/job-configuration' 不是 'NCName' 的有效值。"

如有任何意见，我们将不胜感激。谢谢。

Answer 2

为了避免，JobController空指针异常，放在下面

server.servletPath=/*

此致，吉格尔.

Answer 3

终于找到了在maven项目中做注解@EnableBatchAdmin的方法

这允许您修复以下错误。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'batchMBeanExporter' defined in URL [jar:file:/C:/Users/Admin/.m2/repository/org/springframework/batch/spring-batch-admin-manager/2.0.0.BUILD-SNAPSHOT/spring-batch-admin-manager-2.0.0.BUILD-SNAPSHOT.jar!/META-INF/spring/batch/bootstrap/manager/jmx-context.xml]: Cannot create inner bean 'org.springframework.aop.framework.ProxyFactoryBean#7807ac2c' of type [org.springframework.aop.framework.ProxyFactoryBean] while setting bean property 'jobService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.framework.ProxyFactoryBean#7807ac2c': Post-processing of FactoryBean's object failed; nested exception is java.lang.IllegalStateException: @Scheduled method 'removeInactiveExecutions' found on bean target class 'SimpleJobService' but not found in any interface(s) for a dynamic proxy. Either pull the method up to a declared interface or switch to subclass (CGLIB) proxies by setting proxy-target-class/proxyTargetClass to 'true'.

在这个问题中找到了解决方案https://github.com/spring-projects/spring-batch-admin-samples/issues/12

并通过以下

覆盖jmx-context.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:mbean-server id="mbeanServer"/>

<context:mbean-export default-domain="spring.application" server="mbeanServer"/>

<!-- Override the `batchMBeanExporter` and set the `proxyTargetClass` property to true on the `jobService` proxy.
    This is a workaround for the related https://jira.spring.io/browse/BATCHADM-126 -->
<bean id="batchMBeanExporter" class="org.springframework.batch.admin.jmx.BatchMBeanExporter">
    <property name="server" ref="mbeanServer"/>
    <property name="jobService">
        <bean class="org.springframework.aop.framework.ProxyFactoryBean">
            <property name="targetName" value="jobService"/>
            <property name="proxyTargetClass" value="true"/>
        </bean>
    </property>
    <property name="defaultDomain" value="spring.application"/>
</bean>

通过将此代码放入您自己的 jmx.context.xml 文件中 main/resources/META-INF/spring/batch/override
