java 番石榴库和 GWT

Guava libraries and GWT

提问by jldupont

Just discovered the Guava librariesproject.

刚刚发现了番石榴库项目。

Do these work with GWT?

这些对 GWT 有用吗？

From the introductory PDF on that page,

从该页面的介绍性 PDF 中，

You can use these libraries on...

• On JDK 6
• On Android
  We think. Need volunteers to help us test it out.
• On Google App Engine
  We think. Need volunteers to help us test it out.
• On GWT -- spotty!
  Because GWT's JDK library support is spotty
  Maybe 2/3 the stuff in these libraries is GWT-safe so far
  Just look for @GwtCompatible!
  Performance? Not necessarily good.

您可以在...上使用这些库

• 在 JDK 6 上
• 在 Android
  我们认为。需要志愿者帮助我们进行测试。
• 关于 Google App Engine
  我们认为。需要志愿者帮助我们进行测试。
• 在 GWT 上——参差不齐！
  因为 GWT 的 JDK 库支持参差不齐
  ，到目前为止，这些库中的内容可能是 GWT 安全的 2/3
  只需寻找@GwtCompatible！
  表现？不一定好。

Here are some more details on how to accomplish this with the (currently latest) 19.0release of Guava.

以下是有关如何使用（当前最新的）19.0Guava 版本完成此操作的更多详细信息。

1. The Guava release consists of two JARs, guava-19.0.jarand guava-gwt-19.0.jar. You will need bothfor getting Guava to work within your GWT project. (In a non-GWT project you will only need the former.) Download them and add them to your project; if you use Maven, use these dependencies:

   <dependency>
       <groupId>com.google.guava</groupId>
       <artifactId>guava</artifactId>
       <version>19.0</version>
   </dependency>
   <dependency>
       <groupId>com.google.guava</groupId>
       <artifactId>guava-gwt</artifactId>
       <version>19.0</version>
   </dependency>
   

   Maven will then automatically download the two Jars from the Central Maven Repository, see also the Guava page on mvnrepositories. As an SBT user, you would go for something like libraryDependencies += "com.google.guava" % "guava" % "19.0".

2. Add

     <inherits name="com.google.common.collect.Collect"/>
   

   to your GWT module file to enable Guava.

1. Guava 版本由两个 JARguava-19.0.jar和guava-gwt-19.0.jar. 您将需要两者才能让 Guava 在您的 GWT 项目中工作。（在非 GWT 项目中，您只需要前者。）下载它们并将它们添加到您的项目中；如果您使用 Maven，请使用这些依赖项：

   <dependency>
       <groupId>com.google.guava</groupId>
       <artifactId>guava</artifactId>
       <version>19.0</version>
   </dependency>
   <dependency>
       <groupId>com.google.guava</groupId>
       <artifactId>guava-gwt</artifactId>
       <version>19.0</version>
   </dependency>
   

   然后 Maven 将自动从中央 Maven 存储库下载两个 Jars ，另请参阅mvnrepositories 上的Guava 页面。作为SBT 用户，您会选择类似libraryDependencies += "com.google.guava" % "guava" % "19.0".

2. 添加

     <inherits name="com.google.common.collect.Collect"/>
   

   到您的 GWT 模块文件以启用 Guava。

In the future, we'll release a working GWT module covering the @GwtCompatible subset of the library. Stay tuned.

将来，我们将发布一个工作 GWT 模块，涵盖库的 @GwtCompatible 子集。敬请关注。
