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

Question

我将被介绍给pivotal GemFire，所以我在 spring 中创建了一个入门项目，并在 spring 指南中复制了以下项目。

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

这个项目正在工作，数据被持久化，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环境变量，并且能够运行 GemFire 的命令行"gfsh" .

1) 现在我的问题是如何在这个命令行 gfsh 中查看持久化数据（通过 spring-data-gemfire 持久化）。所以，我真的可以看到它是如何存储的等等。

2) 另外，在上面的 spring 项目中，虽然它工作正常，但它的抛出异常为

那么怎么解决呢，和上面的问题（问题1）有什么关系

请帮助这个新手..谢谢

Answer 1

1) 您有几个选项可以使用 Gfsh 查看从基于 Spring Data GemFire 的应用程序中持久保存到 GemFire 的数据。

1.a) 您可以像这样从 gfsh 命令行执行 OQL...

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

例如...

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

有关详细信息，请参阅 GemFire 文档...

• http://gemfire.docs.pivotal.io/docs-gemfire/latest/tools_modules/gfsh/command-pages/query.html
• http://gemfire.docs.pivotal.io/docs-gemfire/latest/developing/querying_basics/chapter_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/监控工具的一个组件。

• http://gemfire.docs.pivotal.io/docs-gemfire/latest/tools_modules/pulse/chapter_overview.html
• http://gemfire.docs.pivotal.io/docs-gemfire/latest/tools_modules/pulse/quickstart.html#topic_F0ECE9E8179541CCA3D6C5F4FBA84404（向下滚动到“数据浏览器”部分）。

以下文档解释了如何从 Gfsh...

启动/启动 Pulse

• http://gemfire.docs.pivotal.io/docs-gemfire/latest/tools_modules/pulse/quickstart.html#topic_523F6DE33FE54307BBE8F83BB7D9355D

基本上...

gfsh>start pulse

定位器/管理器启动后。

2) 至于异常，GemFire 目前有一个错误，即使 GemFire 服务器节点不是“管理器”，它也会尝试加载管理命令类。此异常是良性的，但您可以通过在类路径中包含 Spring Shell 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>

如果您没有使用 Maven 或 Gradle，那么您可以按照异常消息状态执行操作，并将 $GEMFIRE_HOME/lib/gfsh-dependencies 放在您的应用程序类路径中（可能在您的 IDE 中）。

但是，如果您遵循 Spring 指南，那么您使用的是 Maven 或 Gradle。

希望这会有所帮助！

干杯， 约翰
