通过Gwt.create(Interface.class)，根据自己给定规则，自动生成InterfaceImpl类:
1.定义exportGenerator 模块
xml代码
- < module>
-
- < inherits name='com.google.gwt.user.User'/>
-
- < generate-with class="exporter.rebind.ExporterHelperGenerator" >
- < when-type-assignable class="exporter.client.IExportableHelper"/>
- < /generate-with>
-
- < /module>
interface 接口继承IExportableHelper，通过ExporterHelperGenerator自动构造.
2.创建SourceWrite写文件：
java 代码
- PrintWriter printWriter = ctx.tryCreate(logger, packageName,generatedSimpleName);
-
-
- ClassSourceFileComposerFactory composerFactory = new ClassSourceFileComposerFactory(packageName, generatedSimpleName);
-
- composerFactory.addImport(JavaScriptObject.class.getName());
-
- composerFactory.addImplementedInterface(serviceInterfaceClassType.getSimpleSourceName());
-
-
- SourceWriter sw = composerFactory.createSourceWriter(ctx,printWriter);
3.至此,通过 SourceWrite 写我们想要自动生成的方法
java 代码
- sw.println( " public native void method1( ) /*-{ " );
-
- sw.indent();
-
- sw.println( " alert( ' hello! ' )" );
-
- sw.outdent();
-
- sw.println(" } -*/");
- sw.commit(TreeLogger);
