如何从外部库共享bean到GWT客户端？ [英] How can share bean from external library to GWT client?

问题描述

我有一个关于将库中的java bean共享给gwt客户端的问题
我知道GWT客户端和服务器之间的bean共享，通常放入包domain.shared。

然而，如何在GWT客户端上使用外部jar库中的现有bean？

因为我总是收到这条消息。
没有源代码可用于类型xxxx.xxxx.bean您是否忘记继承所需的模块？

解决方案

假定您的bean位于 xxx.xxx.bean 包中，并且它们位于导入的 my_beans.jar 库中。
$ b

在应用程序中创建一个文件夹 src 树（或 src / main / java 如果您使用的是maven）名称 xxx / xxx

创建一个新的

 <$ c $   C><模块> 
<继承了name ='com.google.gwt.user.User'/> 
< source path =bean/> 
< / module> 
  

编辑您的 Application.gwt.xml 和添加此行

 < inherits name =xxx.xxx.MyBeans/> 
  

请注意， xxx.xxx.bean package必须使用GWT支持的类。

您应该检查 my_beans.jar 库包含要使用的bean的Java源文件。

I have a question about share the java bean in library to gwt client I know bean share between GWT client and server usually put into package domain.shared.

However, how can I make use of existing bean from external jar library on GWT client?

Because I always got this message. No source code is available for type xxxx.xxxx.bean did you forget to inherit a required module?

解决方案

Given that your beans are in the package xxx.xxx.bean, and they are in an imported my_beans.jar library.

Create a folder in your Application src tree (or src/main/java if you are using maven) with the name xxx/xxx

Create a new Module file in this folder called MyBeans.gwt.xml with this content:

<module>
  <inherits name='com.google.gwt.user.User'/>
  <source path="bean"/>
</module>

Edit your Application.gwt.xml and add this line

<inherits name="xxx.xxx.MyBeans"/>

Be aware that all Classes in the xxx.xxx.bean package must use classes supported by GWT.

You should check as well that the my_beans.jar library includes the java source files of the beans you are going to use.
