如何在gemfire命令行gfsh中查看持久化数据(持久化通过spring-data-gemfire)

Question

我开始介绍关键GemFire，所以我在spring创建了一个初学者项目，并在spring指南中复制了下面的项目。

https://spring.io/guides/gs/accessing-data-gemfire/

而且这个项目的工作数据是持久化的，我也可以检索数据。

另一方面，我已经下载了"GemFire 8.2.1“并安装在我的系统中，并设置了所有env变量，并且能够运行GemFire conmmandLine。

1)现在我的问题是如何查看这个命令行gfsh中的持久化数据(持久化通过spring gemfire)。所以，我能真正看到它是如何储存的等等。

2)此外，在上面的spring项目中，虽然它运行良好，但抛出的异常情况如下

那么如何解决这一问题，与上述问题有任何关系(问题1)。

请帮助这个纽比..。谢谢

Answer 1

1)您可以使用Gfsh从基于Spring的应用程序中看到数据持久化到GemFire的几个选项。

1.a)可以从gfsh命令行执行OQL，如下所示.

gfsh>query --query="SELECT * FROM /<your region name here> WHERE <predicates here>"

例如..。

SELECT c.name FROM /Customers c WHERE c.age > 21

有关更多细节，请参见GemFire文档..。

• 模块/gfsh/命令-page/query.html
• overview.html

1.b)您还可以选择使用GemFire的数据浏览器工具，它是GemFire脉冲管理/监视工具的一个组件。

• overview.html
• F0ECE9E8179541CCA3D6C5F4FBA84404 (向下滚动到“数据浏览器”部分)。

下面的文档解释了如何从Gfsh启动/启动脉冲。

• 523 F6DE33FE54307BBE8F83BB7D9355D

本质上..。

gfsh>start pulse

在定位器/管理器启动后。

2)至于异常，GemFire当前有一个错误，它尝试加载管理命令类，即使GemFire服务器节点不是“管理器”。此异常是良性的，但您可以通过在类路径上包含Spring依赖项来消除它。例如，使用Maven，您将声明以下依赖项..。

<dependency>
  <groupId>org.springframework.shell</groupId>
  <artifactId>spring-shell</artifactId>
  <version>1.0.0.RELEASE</version>
  <scope>runtime</scope>
  <exclusions>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context-support</artifactId>
    </exclusion>
  </exclusions>
</dependency>

如果不使用Maven或Gradle，则可以将$GEMFIRE_HOME/lib/gfsh-依赖项作为异常消息状态放在应用程序类路径(可能在IDE中)中。

但是，如果您正在遵循Spring，那么您将使用Maven或Gradle。

希望这能有所帮助！

干杯，约翰
