PHP / Java桥接问题
我在Windows上使用tomcat 6。 这是我正在测试的代码。
import java.io.ByteArrayOutputStream; import java.io.Closeable; import java.io.StringReader; import javax.script.Invocable; import javax.script.ScriptEngine; import javax.script.ScriptEngineManager; /** * Create and run THREAD_COUNT PHP threads, concurrently accessing a * shared resource. * * Create 5 script engines, passing each a shared resource allocated * from Java. Each script engine has to implement Runnable. * * Java accesses the Runnable script engine using * scriptEngine.getInterface() and calls thread.start() to invoke each * PHP Runnable implementations concurrently. */ class PhpThreads { public static final String runnable = new String("getAttribute('sharedResource', 100);\n" + " $nr = (string)java_context()->getAttribute('nr', 100);\n" + " echo \"started thread: $nr\n\";\n" + " for($i=0; $iwrite(ord($nr));\n" + " java('java.lang.Thread')->sleep(1);\n" + " }\n" + "}\n" + "?>\n"); static final int THREAD_COUNT = 5; public static void main(String[] args) throws Exception { ScriptEngineManager manager = new ScriptEngineManager(); Thread threads[] = new Thread[THREAD_COUNT]; ScriptEngine engines[] = new ScriptEngine[THREAD_COUNT]; ByteArrayOutputStream sharedResource = new ByteArrayOutputStream(); StringReader runnableReader = new StringReader(runnable); // create THREAD_COUNT PHP threads for (int i=0; i<THREAD_COUNT; i++) { engines[i] = manager.getEngineByName("php-invocable"); if (engines[i] == null) throw new NullPointerException ("php script engine not found"); engines[i].put("nr", new Integer(i+1)); engines[i].put("sharedResource", sharedResource); engines[i].eval(runnableReader); runnableReader.reset(); // cast the whole script to Runnable; note also getInterface(specificClosure, type) Runnable r = (Runnable) ((Invocable)engines[i]).getInterface(Runnable.class); threads[i] = new Thread(r); } // run the THREAD_COUNT PHP threads for (int i=0; i<THREAD_COUNT; i++) { threads[i].start(); } // wait for the THREAD_COUNT PHP threads to finish for (int i=0; i<THREAD_COUNT; i++) { threads[i].join(); ((Closeable)engines[i]).close(); } // print the output generated by the THREAD_COUNT concurrent threads String result = sharedResource.toString(); System.out.println(result); // Check result Object res=manager.getEngineByName("php").eval( ""); System.exit(((Number)res).intValue()); } } 我添加了所有库。 当我运行该文件时，我收到以下错误 –
run: Exception in thread "main" javax.script.ScriptException: java.io.IOException: Cannot run program "php-cgi": CreateProcess error=2, The system cannot find the file specified at php.java.script.InvocablePhpScriptEngine.eval(InvocablePhpScriptEngine.java:209) at php.java.script.SimplePhpScriptEngine.eval(SimplePhpScriptEngine.java:178) at javax.script.AbstractScriptEngine.eval(AbstractScriptEngine.java:232) at PhpThreads.main(NewClass.java:53) Caused by: java.io.IOException: Cannot run program "php-cgi": CreateProcess error=2, The system cannot find the file specified at java.lang.ProcessBuilder.start(ProcessBuilder.java:459) at java.lang.Runtime.exec(Runtime.java:593) at php.java.bridge.Util$Process.start(Util.java:1064) at php.java.bridge.Util$ProcessWithErrorHandler.start(Util.java:1166) at php.java.bridge.Util$ProcessWithErrorHandler.start(Util.java:1217) at php.java.script.CGIRunner.doRun(CGIRunner.java:126) at php.java.script.HttpProxy.doRun(HttpProxy.java:63) at php.java.script.CGIRunner.run(CGIRunner.java:111) at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:60) Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.(ProcessImpl.java:81) at java.lang.ProcessImpl.start(ProcessImpl.java:30) at java.lang.ProcessBuilder.start(ProcessBuilder.java:452) ... 8 more
我错过了什么？
只需将其添加到命令行：
-Dphp.java.bridge.php_exec =的/ usr /斌/ PHP
问题解决了！
将php5ts.dll和php-cgi.exe的PHP的正确版本复制到“WEB-INF \ cgi \ amd64-windows”目录。 然后重启Tomcat。 祝你好运。
… php-cgi …系统找不到指定的文件
我猜是manager.getEngineByName（“php-invocable”）应该返回一个运行PHP的系统调用的包装器 – 但是这个包装器不知道在哪里可以找到PHP可执行文件。
快速浏览一下PHP / Java桥的网站，我推断该路径是用Java硬编码的 – “有关详细信息，请参阅文档下载中的INSTALL.J2EE文件”
Javadoc在这个主题上显然含糊不清。
你需要在编译时专门制作PHP的-cgi版本，假设你已经完成了，它被称为php-cgi，然后作为一个快速的黑客你可以使用名为“php-cgi”的链接来覆盖你的文件系统（它的可能应该在/ bin，/ usr / bin /，/ usr / local / bin中，或者Java可能足够智能来检查$ PATH）
C。

使用JavaBridge.war部署（windows，tomcat）
请在环境变量中指定php安装的路径 。
