java - 无法启动嵌入式 Google App Engine 服务器进行集成测试

Question

我正在尝试在由 maven 故障安全插件运行的测试套件的 @BeforeClass 中启动嵌入式 Google App Engine 开发服务器 (sdk 1.7.3)。应该启动它的代码如下所示:

private static final String HOST = "0.0.0.0";
private static final int PORT = 8887;
private static DevAppServer devAppServer;


@BeforeClass
public static void setup() throws Exception {
    log.debug("Starting development server");
    File appRootDir = new File("target/visualize-1.0.war");
    DevAppServerFactory devAppServerFactory = new DevAppServerFactory();
    devAppServer = devAppServerFactory.createDevAppServer(appRootDir, HOST, PORT); 
    devAppServer.start();
}

但是在调用 createDevAppServer 期间，我遇到了一个安全异常:

java.security.AccessControlException: access denied (java.lang.RuntimePermission setContextClassLoader)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:374)
at java.security.AccessController.checkPermission(AccessController.java:546)

使用 -Djava.security.debug=access,failure 调试安全异常我看到了:

  access: access allowed (java.io.FilePermission    /home/me/.m2/repository/com/google/appengine/appengine-tools-sdk/1.7.3/appengine-tools-sdk-1.7.3.jar read)

我做错了什么？

Answer 1

实际上，您不应该像以前那样调用 GAE(提示:GAE 有很多补丁来处理安全问题，这根本不值得)

但是，maven-gae-plugin 确实有 gae:start 和 gae:stop 是专门为 IT 设计的。

这就是我将它用于 IT 的方式:
