jersey - 在 Dropwizard 中运行测试时没有安装 ServiceLocatorGenerator 错误

Question

我已经在我的项目中升级了 Dropwizard 并在运行单元测试时遇到了问题，虽然服务启动工作正常并且所有 API 都运行正常，但只有在运行测试时才会出现问题，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

以下是我运行“mvn test”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

调用 JerseyGuiceUtils在运行测试或应用程序可以提供帮助之前。

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