java - Appengine 云端点 v2：在 devserver 中指定数据存储

Question

我按照迁移文档和 git repo ( https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine/endpoints-frameworks-v2 ) 中的 v2 示例迁移到云端点 v2。但是，我不确定如何设置 jvmFlag(s) 以指定其他属性，如 backend_store、端口、启用调试等，就像它在 v1 中一样。

这是我的 pom.xml 中的构建标签。

请帮助配置 jvmFlags。

Answer 1

这是指定 jvmFlags 的解决方案之一

        <plugin>
            <groupId>com.google.cloud.tools</groupId>
            <artifactId>appengine-maven-plugin</artifactId>
            <version>1.3.1</version>
            <configuration>
                <!--<devserver.storagePath>/Users/user/Documents/development/health/local_db.bin</devserver.storagePath>-->
                <devserver:port>8181</devserver:port>
                <devserver.jvmFlags>-Xdebug</devserver.jvmFlags>
                <devserver.jvmFlags>-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n</devserver.jvmFlags>
                <devserver.jvmFlags>-Ddatastore.backing_store=/Users/user/Documents/development/health/local_db.bin</devserver.jvmFlags>
            </configuration>
        </plugin>
