我正在尝试在 gae 上使用谷歌云端点。我正在尝试将它集成到 Maven 中。我发现这个 maven 插件可以这样做： http ://code.google.com/p/maven-endpoint-plugin/

我能够定义我的 api 并生成 api。当我的 api 部署在应用程序引擎上时，我可以调用它。但是当我尝试在本地调用它进行调试时，我得到以下异常：

而且我也无法生成客户端库（执行 mvn compile 或使用 google eclipse 插件）

有没有人成功地将 google cloud enpoints 与 maven 集成： - 生成客户端库 - 在本地测试 - 部署到应用程序引擎并使其工作（这是唯一的步骤，我设法开始工作）

如果您依赖 com.google.appengine appengine-endpoints 1.7.7 com.google.appengine appengine-api-1.0-sdk 1.7.7 javax.servlet servlet-api 2.5

并且您使用 Google App Engine Maven 插件 1.7.7：

        <plugin>
            <groupId>com.google.appengine</groupId>
            <artifactId>appengine-maven-plugin</artifactId>
            <version>1.7.7</version>
            <executions>
                <execution>
                    <phase>compile</phase>
                    <goals>
                        <goal>endpoints_get_discovery_doc</goal>
                        <!--goal>endpoints_get_client_lib</goal-->
                    </goals>
                </execution>
            </executions>
            <configuration>
                <serviceClassNames>YOURENDPOINTSCLASSES(comma separated)</serviceClassNames>
            </configuration>
        </plugin>

你很高兴实现这两个目标：enpoints_get_discovery_doc 和 endpoints_get_client_lib

我终于能够在我的本地端点服务器上运行我的端点。该异常与 Maven 插件无关。我没有正确使用 enpoint 注释，这就是为什么我一直有这个异常。我无法弄清楚为什么它可以在 gae 生产服务器上运行。这是错误：我写了

public void deleteProject(@Named Long projectId) {
    projectManager.deleteProject(projectId);
}

而不是写

public void deleteProject(@Named("id") Long projectId) {
    projectManager.deleteProject(projectId);
}

我忘记为我的一些方法定义“@Named”注释的名称参数。

添加这个

<dependency>
    <groupId>com.google.appengine</groupId>
    <artifactId>appengine-endpoints</artifactId>
    <version>1.7.6</version>
    <scope>runtime</scope>
</dependency>

到您的 Maven 依赖项（当然，我使用的是 1.7.6 版本）

你能发布你的 pom.xml 吗？
