如何在CF中获取java类 [英] How to get java class in CF
问题描述
我想从我的coldfusion文件中的java方法访问返回值。我已经加载所有的jar文件在coldfusion文件，并获得了java类对象成功。使用类对象，我想访问java类方法，它返回一个 Set ;但我不能得到任何返回值。
这是我的Java代码：
I want to access the return value from a java method in my coldfusion file. I have loaded all the jar files in coldfusion file and got the java class object successfully. Using the class object, I want to access java class method which returns a Set; but I can't get any return value.
Here is my Java Code:
public Set getSession(String url) {
result+="hello";
try {
DesiredCapabilities caps = new DesiredCapabilities();
caps.setJavascriptEnabled(true);
caps.setCapability("takesScreenshot", false);
caps.setCapability(
PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
"E:\\TicketScraper\\phantomjs\\phantomjs.exe"
);
driver = new PhantomJSDriver(caps);
driver.get(url);
driver.findElement(By.id("login:loginName")).sendKeys("XXXX");
driver.findElement(By.id("login:password")).sendKeys("XXXX");
waitForJQueryProcessing(driver, 5);
driver.findElement(By.id("login:j_idt145")).click();
Thread.sleep(10000);
Set<org.openqa.selenium.Cookie> allCookies=driver.manage().getCookies();
for ( org.openqa.selenium.Cookie loadedCookie : allCookies) {
System.out.println(String.format("%s -> %s", loadedCookie.getName(),loadedCookie.getValue()));
}
} catch(Exception e) {
System.out.println(e);
}
return allCookies;
}
java代码运行Phantom JS驱动程序，登录到上面的代码，并获取所有的cookie。所有cookie都收集在 Set 变量中，并从方法中返回。我想在CF代码中获得这个设置变量。
The java code runs the Phantom JS driver, logs in to the URL in the above code, and gets all cookies. All cookies are collected in a Set variable and returned from the method. I want to get this set variable in CF code.
但是当我试图访问java方法的 Set 在CF中的变量不返回任何值。相比之下，当我注释掉所有Phantom JS代码并只返回一个 String 变量，然后CF可以访问字符串值。
这是我的CF代码：
But when I have tried to access the java method's Set variable in CF it doesn't return any value. By contrast, when I have commented out all the Phantom JS code and return only a String variable then CF can access the string value.
Here is my CF code:

请提供您如何访问CF中Phantom JS值的建议。
Please provide your suggestions of how to access the Phantom JS value in CF.
推荐答案
假设你的 Set 是一个 java.util.Set ，然后调用 toArray（）会给你一个容易在CF中访问的数组。
Assuming your Set is a java.util.Set, then calling toArray() would give you an array that's easily accessible in CF.
例如
<cfscript>
s = createObject("java", "java.util.HashSet").init();
s.add("foo");
s.add("bar");
s.add("bob");
arr = s.toArray();
writeDump(arr);
</cfscript>
