在GWT项目中继承外部Java源代码 [英] Inherit external java source in GWT project
问题描述
我有一个在服务器端使用的ENUM。
我希望可以巧妙地在客户端(GWT)使用这个枚举。
这是结构:
se.mycompany.core
se.mycompany.core.TheEnum< - this Enum。
se.mycomapny.web.gwtproject< - GWT项目。
se.mycomapny.web.gwtproject.client
我试着添加
< inherits name =se.mycompany.core.TheEnum/>
添加到我的gwtproject.gwt.xml文件中。但是,我收到以下错误消息:
[p] [错误]无法在您的类路径中找到'se / mycompany / core / TheEnum.gwt.xml';可能是一个错字,或者你忘了为源代码包含类路径条目?
我试图将文件TheEnum.gwt.xml添加到'se / mycompany /核心/'与以下上下文。
< module>
<继承了name ='com.google.gwt.user.User'/>
< source path =TheEnum>< / source>
< / module>
但它仍抱怨同样的事情。
我猜我需要将se.mycompany.core.TheEnum添加到build.xml中的类路径中,但我不知道如何或在哪里。
inherits标记用于导入其他模块,而不是单个类。您可以通过在核心
包下创建一个简单的GWT模块,然后在现有模块中继承该模块来达到目的:
在包 se.mycompany.core
下使用以下命令创建名为 Core.gwt.xml
的文件内容:
<?xml version =1.0encoding =UTF-8?>
< module>
< source path =includes =TheEnum.java/>
< / module>
然后在您现有的模块中添加:
< inherits name ='se.mycompany.core.Core'/>
I have an ENUM that is used on the server-side. I want to be ably to use this enum on the client side (GWT) aswell.
This is the structure:
se.mycompany.core
se.mycompany.core.TheEnum <-- this Enum.
se.mycomapny.web.gwtproject <-- The GWT project.
se.mycomapny.web.gwtproject.client
I have tried to add
<inherits name="se.mycompany.core.TheEnum"/>
to my gwtproject.gwt.xml file. But I get the following error message:
[ERROR] Unable to find 'se/mycompany/core/TheEnum.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?
I have tried to add the file TheEnum.gwt.xml to 'se/mycompany/core/' with the following context.
<module>
<inherits name='com.google.gwt.user.User'/>
<source path="TheEnum"></source>
</module>
But it still complains about the same thing.
I'm guessing I need to add the se.mycompany.core.TheEnum to the classpath in build.xml somehow, but I dont know how or where.
The "inherits" tag is used to import other modules, not individual classes. You could achieve what you want by creating a simple GWT module under the core
package, and then inherit that module in the existing one:
Create a file called Core.gwt.xml
under package se.mycompany.core
with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<module>
<source path="" includes="TheEnum.java"/>
</module>
Then in your existing module add:
<inherits name='se.mycompany.core.Core'/>
