Appengine雲端點v2：在devserver中指定數據存儲區

Question

我根據git repo（ https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine/endpoints-frameworks-v2 ）上的遷移文檔和v2示例遷移到了雲端點v2。 但是，我不確定如何設置jvmFlag來指定其他屬性，例如backend_store，端口，啟用調試等，就像在v1中一樣。

這是我pom.xml中的build標記。

請幫助配置jvmFlags。

Answer 1

這是指定jvmFlags的解決方案之一

        <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>
