CDI 无法注入 FirefoxDriver (Selenium)
CDI Can't inject FirefoxDriver (Selenium)
我正在尝试在需要时使用 CDI 注入 firefox（避免总是配置驱动程序）。但我总是得到 NullPointer.
我为 firefox 驱动程序创建了一个 生产者
@ApplicationScoped
public class FirefoxDriverProducer {
@Produces @RequestScoped
public FirefoxDriver getDriver() {
// Inicia o Firefox pelo Selenium
String caminhoFirefox = "/usr/bin/firefox";
String profileFirefox = "Selenium";
// Aponta o caminho para o firefox
File pathToBinary = new File(caminhoFirefox);
FirefoxBinary ffBinary = new FirefoxBinary(pathToBinary);
// Profile que precisa ser criado no firefox
ProfilesIni profile = new ProfilesIni();
FirefoxProfile myprofile = profile.getProfile(profileFirefox);
// Proxy
String PROXY = "companyproxy:8080";
org.openqa.selenium.Proxy proxy = new org.openqa.selenium.Proxy();
proxy.setHttpProxy(PROXY).setFtpProxy(PROXY).setSslProxy(PROXY);
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability(CapabilityType.PROXY, proxy);
FirefoxDriver driver = new FirefoxDriver(ffBinary, myprofile, cap);
return driver;
}
public void close(@Disposes FirefoxDriver driver) {
driver.quit();
}
}
当我想使用它时，我这样称呼它：
@Inject
private FirefoxDriver driver;
就像我想注入的任何其他对象一样。
但是我总是得到 NullPointer，当我尝试调试驱动程序时它总是空的，通过在生产者方法中放置一个断点 getDriver() 它甚至没有被调用...
在同一个项目中，我已经用 FacesContext 和 NavigationHandler 做了类似的事情，他们都工作得很好。
ps：我是 运行 Wildfly 8，beans.xml 在我的 web-inf 上。
ps2: 我这样做是因为我需要访问另一个公司网站并不时下载一些信息，因为他们不提供任何网络服务或其他任何东西, 只能通过网络浏览器。
ps3：如果我不使用 CDI 并从生产者那里获取所有代码并将其放在 class 上，我认为它工作正常。所以我假设这不是 Selenium

我的 Download class，其中我注入了 FireFoxDriver：
public class DownloadCsr {
@Inject
private FirefoxDriver driver;
public DownloadCsr(String usuario, String senha, LocalDateTime dataInicial,
LocalDateTime dataFinal) throws LoginException {
driver.get("https://companysite.net");
// Encontra o elemento para inserir o usuario
WebElement webUsuario = getElementByLocator(By.name("USER"), driver);
// Insere o usuario
webUsuario.sendKeys(usuario);
// Encontra o elemento para inserir a senha
WebElement webSenha = getElementByLocator(By.name("PASSWORD"), driver);
// Insere a senha
webSenha.sendKeys(senha);
// Acha o bot�o de login e clica
WebElement button = getElementByLocator(By.name("IMAGE1"), driver);
button.click();
// Confere se logou na pagina verificando o titulo dela, do contrario
// lança a exceção
if (!driver.getTitle().equals("Business Home")) {
throw new LoginException("Can't reach the loged-in page");
}
}
为了测试，我使用了以下内容。
@Named
@RequestScoped
public class TesteBean implements Serializable {
public void teste() {
LocalDateTime dataInicial = LocalDateTime.now().minusDays(1);
LocalDateTime dataFinal = LocalDateTime.now();
try {
new DownloadCsr("login", "password",
dataInicial, dataFinal);
} catch (LoginException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
您的问题来自于 DownloadCsr 不是一个 bean。它有一个带参数的构造函数，您可以在 class TesteBean 中实例化它。要获得 CDI 功能，您必须让 CDI 容器为您实例化 bean，并像其他可注入 bean 一样提供所有需要的信息。换句话说：使用 new 给你一个非托管的未注入实例。
将业务代码放在构造函数中也是一种不好的做法。构造函数应该只包含初始化代码。在字段的构造函数 none 期间被注入，所以即使你的 DownloadCsr 满足成为 bean 的要求，你的构造函数中也会有一个 NPE。
你可以做的是这样的事情：
@Named
@RequestScoped
public class TesteBean implements Serializable {
@Inject
private DownloadCsr dcsr;
public void teste() {
LocalDateTime dataInicial = LocalDateTime.now().minusDays(1);
LocalDateTime dataFinal = LocalDateTime.now();
try {
dcsr.crawl("login","password", dataInicial, dataFinal);
} catch (LoginException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
与以下 DownloadCsr
public class DownloadCsr {
@Inject
private FirefoxDriver driver;
public void crawl(String usuario, String senha, LocalDateTime dataInicial,
LocalDateTime dataFinal) throws LoginException {
driver.get("https://companysite.net");
// Encontra o elemento para inserir o usuario
WebElement webUsuario = getElementByLocator(By.name("USER"), driver);
// Insere o usuario
webUsuario.sendKeys(usuario);
// Encontra o elemento para inserir a senha
WebElement webSenha = getElementByLocator(By.name("PASSWORD"), driver);
// Insere a senha
webSenha.sendKeys(senha);
// Acha o boto de login e clica
WebElement button = getElementByLocator(By.name("IMAGE1"), driver);
button.click();
// Confere se logou na pagina verificando o titulo dela, do contrario
// lança a exceção
if (!driver.getTitle().equals("Business Home")) {
throw new LoginException("Can't reach the loged-in page");
}
}
}

我的 Download class，其中我注入了 FireFoxDriver：
public class DownloadCsr {
@Inject
private FirefoxDriver driver;
public DownloadCsr(String usuario, String senha, LocalDateTime dataInicial,
LocalDateTime dataFinal) throws LoginException {
driver.get("https://companysite.net");
// Encontra o elemento para inserir o usuario
WebElement webUsuario = getElementByLocator(By.name("USER"), driver);
// Insere o usuario
webUsuario.sendKeys(usuario);
// Encontra o elemento para inserir a senha
WebElement webSenha = getElementByLocator(By.name("PASSWORD"), driver);
// Insere a senha
webSenha.sendKeys(senha);
// Acha o bot�o de login e clica
WebElement button = getElementByLocator(By.name("IMAGE1"), driver);
button.click();
// Confere se logou na pagina verificando o titulo dela, do contrario
// lança a exceção
if (!driver.getTitle().equals("Business Home")) {
throw new LoginException("Can't reach the loged-in page");
}
}
为了测试，我使用了以下内容。
@Named
@RequestScoped
public class TesteBean implements Serializable {
public void teste() {
LocalDateTime dataInicial = LocalDateTime.now().minusDays(1);
LocalDateTime dataFinal = LocalDateTime.now();
try {
new DownloadCsr("login", "password",
dataInicial, dataFinal);
} catch (LoginException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
您的问题来自于 DownloadCsr 不是一个 bean。它有一个带参数的构造函数，您可以在 class TesteBean 中实例化它。要获得 CDI 功能，您必须让 CDI 容器为您实例化 bean，并像其他可注入 bean 一样提供所有需要的信息。换句话说：使用 new 给你一个非托管的未注入实例。
将业务代码放在构造函数中也是一种不好的做法。构造函数应该只包含初始化代码。在字段的构造函数 none 期间被注入，所以即使你的 DownloadCsr 满足成为 bean 的要求，你的构造函数中也会有一个 NPE。
你可以做的是这样的事情：
@Named
@RequestScoped
public class TesteBean implements Serializable {
@Inject
private DownloadCsr dcsr;
public void teste() {
LocalDateTime dataInicial = LocalDateTime.now().minusDays(1);
LocalDateTime dataFinal = LocalDateTime.now();
try {
dcsr.crawl("login","password", dataInicial, dataFinal);
} catch (LoginException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
与以下 DownloadCsr
public class DownloadCsr {
@Inject
private FirefoxDriver driver;
public void crawl(String usuario, String senha, LocalDateTime dataInicial,
LocalDateTime dataFinal) throws LoginException {
driver.get("https://companysite.net");
// Encontra o elemento para inserir o usuario
WebElement webUsuario = getElementByLocator(By.name("USER"), driver);
// Insere o usuario
webUsuario.sendKeys(usuario);
// Encontra o elemento para inserir a senha
WebElement webSenha = getElementByLocator(By.name("PASSWORD"), driver);
// Insere a senha
webSenha.sendKeys(senha);
// Acha o boto de login e clica
WebElement button = getElementByLocator(By.name("IMAGE1"), driver);
button.click();
// Confere se logou na pagina verificando o titulo dela, do contrario
// lança a exceção
if (!driver.getTitle().equals("Business Home")) {
throw new LoginException("Can't reach the loged-in page");
}
}
}
