Question

我已经在我的项目中升级Dropwizard并在运行单元测试时面临问题，虽然服务启动工作正常并且所有API都正常运行，问题出现在运行测试时，这是我的版本：

Dropwizard: 1.1.0
Jersey: 2.25.1
Guice: 4.1.0
hk2-api: 2.5.0-b36
hk2-utils: 2.5.0-b36
javax.ws.rs-api : 2.1-m05

下面是我正在运行＆＃34; mvn test＆＃34;

时的错误

java.lang.RuntimeException: java.lang.ClassNotFoundException: Provider org.glassfish.jersey.internal.RuntimeDelegateImpl could not be instantiated: java.lang.IllegalStateException: It appears there is no ServiceLocatorGenerator installed.

Answer 1

在运行测试或应用程序之前调用JerseyGuiceUtils会有所帮助。

static {
    JerseyGuiceUtils.install((s, serviceLocator) -> null);
}

Answer 2

看起来像Hk2版本不兼容的版本。
