在单个Weblogic域的同一群集中部署两个Spring批处理应用程序？

java

背景 -

我正在尝试在单个Weblogic域的同一群集中以.war身份部署两个spring批处理应用程序，并且每个应用程序都在servlet.xml中配置了spring批处理管理控制台，如下所示-

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

  <!-- Spring Batch Admin -->  
  <import resource="classpath*:/org/springframework/batch/admin/web/resources/servlet-config.xml"/>
  <import resource="classpath*:/org/springframework/batch/admin/web/resources/webapp-config.xml"/>

  <bean id="resourceService" class="org.springframework.batch.admin.web.resources.DefaultResourceService">
    <property name="servletPath" value="/batch" />
  </bean>

</beans>

它的一个maven项目和spring-batch-admin-manager 1.2.2被作为依赖项引入。

问题-
我正在努力使它们同时运行。目前，我无法让它们同时运行；当其中一个已经运行时，当我尝试启动另一个时，出现以下错误–

weblogic.application.ModuleException: [HTTP:######]Servlet: "myServlet" failed to preload on startup in Web application: "myservice-app.war".

据我了解，问题出在spring-batch-
admin。由于这两个应用程序都试图从其配置中初始化相同的bean，所以我遇到了此错误，但是我不知道如何防止这种情况的发生。

我曾尝试在网上搜索stackoverflow和各种论坛，但找不到解决我问题的方法。有人可以帮忙吗？

我找到了解决此问题的方法。由于无法注册Mbean，因此我们需要覆盖jmx-context.xml，该文件将扫描具有不同域名的jmx Mbean。

在/ META-INF / spring / batch / override /目录下的具有覆盖上下文的批处理项目中的一个项目中创建jmx-
context.xml：覆盖用于扫描的mbean-export和用于集成Mbean的int-jmx：mbean-export，如下所示-

/META-INF/spring/batch/override/jmx-context.xml-

确保为该春季批处理项目更改具有唯一名称的默认域。实施此解决方案后，我使两个批处理应用程序在Weblogic域内的单个群集中同时运行。

重要的是，将jmx-context.xml作为/ appa-INF / spring / batch / override
/作为您在servlet.xml文件中导入的webapp-config.xml放置，以便配置管理控制台，并从该替代中导入所有*
.xml文件夹＆可以用来覆盖任何默认配置。仅供参考，我在这里从spring-batch-admin-manager-resources
jar复制了webapp-config.xml的内容，应将其作为项目中的依赖项引入。

/org/springframework/batch/admin/web/resources/webapp-config.xml-

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

    <!-- Workaround for INT-1831 -->
    <bean id="dummy" class="java.util.Date"/>

    <import resource="classpath*:/META-INF/spring/batch/bootstrap/**/*.xml" />
    <import resource="classpath*:/META-INF/spring/batch/override/**/*.xml" />

        <property name="prefix" value="unpack_"/>
        <property name="putEmptyParamsInPath" value="true"/>
    </bean>

</beans>

以防万一，如果您想知道我们将webapp-
config.xml导入哪里，我放下了servlet.xml的内容来配置批处理管理控制台，您在启动时将其加载到项目的web.xml中。

/WEB-INF/config/spring-beans/servlet.xml-

    <bean id="resourceService" class="org.springframework.batch.admin.web.resources.DefaultResourceService">
        <property name="servletPath" value="/batch" />
    </bean>
