Spring Boot Web Application using Selenium WebDriver
提问by user3054735
I am trying to get my head around spring boot and I am having some issues trying to integrate selenium into my spring boot application. I am trying to achieve a simple web page, which has a input box and button. The input box will contain a URL and the button will then launch a selenium browser navigating to that URL entered.
我正在尝试了解 Spring Boot，但在尝试将 selenium 集成到我的 Spring Boot 应用程序中时遇到了一些问题。我正在尝试实现一个简单的网页，它有一个输入框和按钮。输入框将包含一个 URL，然后该按钮将启动一个 selenium 浏览器，导航到输入的 URL。
I currently have a simple spring boot application consisting of the following:
我目前有一个简单的 spring boot 应用程序，包括以下内容：
index.html
索引.html
Contains an input form (user types URL here) which is passed to myController.
包含传递给 myController 的输入表单（用户在此处键入 URL）。
myController.java
我的控制器
@Controller
public class myController {
@Autowired
private WebDriver driver;
....
}
pom.xml
pom.xml
Contains selenium..
含硒..
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.4.0</version>
</dependency>
My error when I run my project:
运行项目时出现错误：
APPLICATION FAILED TO START
Description:
Field driver in com.project.myController required a bean of type 'org.openqa.selenium.WebDriver' that could not be found.
Action:
Consider defining a bean of type 'org.openqa.selenium.WebDriver' in your configuration.
I am trying to create an instance of Selenium WebDriver so that I can use it whenever I need to. I will only ever need it in this controller, so I declared it here. What am I missing? Any help will be appreciated. Thank you in advance.
我正在尝试创建 Selenium WebDriver 的实例，以便我可以在需要时使用它。我只会在这个控制器中需要它，所以我在这里声明了它。我错过了什么？任何帮助将不胜感激。先感谢您。

You need to have an instance of WebDriver, e.g.:
您需要有一个 WebDriver 实例，例如：
@Bean
public WebDriver webDriver() {
return new WebDriver();
}
in one of your configuration classes. That would be anything annotated with @Configurationor an annotation which includes this; in the most basic Spring Boot application (as used in Spring Boot examples), this would probably be something like this:
在您的配置类之一中。那将是任何带有注释的@Configuration或包含此注释的注释；在最基本的 Spring Boot 应用程序中（在 Spring Boot 示例中使用），这可能是这样的：
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
// Your beans go here
}
because @SpringBootApplicationis annotated with @SpringBootConfigurationwhich is annotated with @Configuration.
因为用@SpringBootApplication注释 用@SpringBootConfiguration注释@Configuration。

I can start spring boot from eclipse than make a GET call to the url localhost:8080/api/cenario/teste. So Selenium open the browser and execute the test cenarios on demand, than I show the results on a web page.
我可以从 eclipse 启动 spring boot，而不是对 url localhost:8080/api/cenario/teste 进行 GET 调用。所以 Selenium 打开浏览器并按需执行测试场景，而不是我在网页上显示结果。
But when I generate a jar file with the project, selenium fail to start the browser.
但是当我用项目生成一个jar文件时，selenium启动浏览器失败。
