java - 关键 GemFire 9.3.0 : Spring Data GemFire XML config in GemFire cluster

Question

我正在将 GemFire 集群从 8.2.7(使用 Spring Data GemFire 1.6.0.RELEASE)迁移到 Pivotal GemFire 9.3.0(SDG 2.0.7.RELEASE)。我使用 spring-context.xml (在 cache.xml 中的 initializer 标记下声明)来初始化区域，同时在每个区域上启动缓存服务器节点。

当我尝试为 Pivotal GemFire 9.3.0 重用相同的 spring-context.xml 时，gfsh 命令无法识别我的 Spring beans 标记，而我出现以下异常:

Caused by: org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 107; cvc-elt.1: Cannot find the declaration of element 'beans'.

        at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203)

        at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.error(ErrorHandlerWrapper.java:134)

spring-context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:gfe="http://www.springframework.org/schema/geode"

    <gfe:replicated-region id="ProductCustomer">

我根据 spring-data-gemfire:2.0.7.RELEASE 的 Spring 文档将 XML 架构路径从“gemfire”更新为“geode” .

尝试使用 GF 9.1.1 和 SDGF 2.0.7。 (SDGF jar放在lib中)

脚本:

#!/bin/sh
export PATH=$PATH:/var/tmp/user/gemfire/9.1.1:/opt/jdk/1.8.0_71l64/bin/:/var/tmp/user/gemfire/9.1.1/bin/
export GEMFIRE=/var/tmp/user/gemfire/9.1.1/


for i in `ls  /var/tmp/user/gemfire/9.1.1/lib/*.jar`
do
  CLASSPATH=${CLASSPATH}:${i}
done
CLASSPATH=$CLASSPATH:/var/tmp/user/gemfire/9.1.1/config
#echo $CLASSPATH

if [ -e "/var/tmp/user/gemfire/9.1.1/config/spring-context.xml" ]; then
   echo "File exists"
else
 echo "File does not exist"
fi


gfsh start server --name=server1 --server-port=40405 --classpath=$CLASSPATH --spring-xml-location=/var/tmp/user/gemfire/9.1.1/config/spring-context.xml  --locators=hostA[10334],hostB[10334] --mcast-port=0

更新:

FileNotFoundException 抛出:

Caused by: java.io.FileNotFoundException: class path resource [var/tmp/sn17180/gemfire/9.1.1/config/spring-context.xml] cannot be opened because it does not exist

        at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:330)

        ... 17 more

我已经授予了所有文件的权限，并且我的脚本中的 -e "/"也打印了“文件存在”。

更新:

自 9.x 版本系列起，Pivotal GemFire 已停止在 $GEMFIRE_HOME/lib 目录中随 Spring Data GemFire 一起提供。造成这种情况的主要原因有两个。

1) 首先，Pivotal GemFire 依赖 SDG 是一个难题，SDG 完全用于 gfsh>start server --name=SpringConfiguredServer --spring-xml-location-/path/to/spring/context.xml，当SDG依赖于Pivotal GemFire时，这显然形成了循环依赖。

2) 在版本方面，Pivotal GemFire 明显落后于 Spring 生态系统的当前状态。即使是最新版本 9.3.0，也附带过时的 Spring JAR，例如核心 Spring Framework 4.3.13.RELEASE，当核心 Spring Framework 4.3.17.RELEASE 已经可用时以及 5.0.6.RELEASE，即将推出 5.1。

话虽如此，当使用启动服务器从Gfsh启动时，仍然可以使用Spring配置和引导您的Pivotal GemFire服务器命令，--spring-xml-location 选项。您只需下载 appropriate version基于您正在使用的 Pivotal GemFire 版本(例如(9.3.0))的 SDG，并在启动服务器时将 SDG 放在类路径上。

NOTE: currently, SDG 2.1.0.M3 (SD Lovelace) is the only version based on Pivotal GemFire 9.3 and later; currently set to 9.5.0.

NOTE: also not, I don't specifically recall whether I ran into any API breaking changes between upgrading SDG Lovelace progressively from Pivotal GemFire 9.3, then to 9.4 and finally arriving at 9.5. If you have trouble with spring-data-gemfire:2.1.0.M3, you can also use spring-data-gemfire:2.1.0.M2 which was based on Pivotal GemFire 9.3 at the time.

因此，按照上面的方法，您将执行以下操作...

gfsh> start server --name=SpringConfiguredServer --classpath=/file/system/path/to/spring-data-gemfire22.1.0.M3.jar --spring-xml-location=/classpath/to/your/spring-context.xml

这应该有效!

此外，您不需要将模式从“gemfire”切换到“geode”。当您使用 Spring Data GemFire 时，请使用“spring-gemfire”模式。当您使用 Spring Data Geode 时，请使用“spring-geode”模式。两者都可能有效，但是...

希望这有帮助!
