配置黄瓜汁 [英] Configuring cucumber-guice

问题描述

我正在尝试在步骤定义中使用DI。我有一个模块，

I am trying to use DI in my step definitions. I have a module,

public class MyModule extends AbstractModule
{
    private final static MyInterface INSTANCE = new MyInterfaceImpl();

    @Override
    protected void configure()
    {
        bind(MyInterface.class).toInstance(INSTANCE);
    }
}

并想将此实例注入到

public class MyStepDefs
{
    private final MyInterface instance;

    @Inject
    public MyStepDefs(MyInterface instance)
    {
        this.instance = instance
    }
}

我想我需要使用Cucumber-guice.properties文件配置GuiceFactory，但我真的不知道这是什么吗？目前我得到的错误是

I think I need to configure the GuiceFactory using a cucumber-guice.properties file but I don't really know what this is? At the moment the error I get is,

java.lang.NoClassDefFoundError: javax/inject/Singleton
    at cucumber.runtime.java.guice.GuiceFactory$CucumberModule.configure(GuiceFactory.java:86)

也应该我正在使用提供者进行构造函数注入？

Also should I be using a Provider for constructor injection?

推荐答案

MyModule 和 MyStepDefs 类很好。 NoClassDefFoundError 是由于没有添加最新版本的Guice作为依赖项引起的。我添加了这个

The MyModule and MyStepDefs classes were fine. The NoClassDefFoundError was caused by not having latest version of Guice added as a dependency. I added this,

<dependency>
  <groupId>com.google.inject</groupId>
  <artifactId>guice</artifactId>
  <version>3.0</version>
</dependency>

到我的 POM.xml 。

cucumber-guice.properties 文件位于 src / main / resources 文件夹。该文件由 GuiceFactory 类读取，并且应包含要使用的Guice模块的属性。 EG ..

The cucumber-guice.properties file goes in the src/main/resources folder. This file is read by the GuiceFactory class and should contain a property for the Guice module you want to use. EG..

guiceModule = com.felix.cucumber.MyModule
