php调用自己的java(转)
-----------------------------推荐方法 : JavaBridge.jar
http://sourceforge.net/projects/php-java-bridge
http://mirror.optus.net/sourceforge/p/ph/php-java-bridge/php-java-bridge_5.2.2_j2ee.zip
最开始要装jdk这个就不用说了,我装的是java ee 5+jdk
1.把下载的php-java-bridge_5.2.2_j2ee.zip解压出来,里面有个JavaBridge.war 直接用winrar打开,到WEB-INF/lib/JavaBridge.jar 把这个jar包拷到 你的php目录的ext/下。
2.打开war包,里面有个java的文件夹,把他全部拷到你的PHP项目下,如/demo/java
3.目前的版本是VMBridge了,要php调用java类,要先启动JavaBridge,
命令行下调用java –jar JavaBridge.jar或者双击JavaBridge.jar,在弹出的窗口中选择监听端口8080
为了以后启动方便,我在ext/下新建了一个bat文件内容如下:
@echo off
start javaw -jar JavaBridge.jar
保存后,双击启动 会有一个提示框选择vmbridge port 默认8080,直接点ok就行了
4.在/demo/下新建test.php内容如下:
<?php
require_once("java/Java.inc");
header("content-type:text/html; charset=utf-8");
// get instance of Java class java.lang.System in PHP
$system = new Java('java.lang.System');
$s = new Java("java.lang.String", "php-java-bridge config...<br><br>");
echo $s;
// demonstrate property access
print 'Java version='.$system->getProperty('java.version').' <br>';
print 'Java vendor=' .$system->getProperty('java.vendor').' <br>';
print 'OS='.$system->getProperty('os.name').' '.
$system->getProperty('os.version').' on '.
$system->getProperty('os.arch').' <br>';
// java.util.Date example
$formatter = new Java('java.text.SimpleDateFormat',
"EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz");
print $formatter->format(new Java('java.util.Date'));
?>
5.启动apache,在浏览器中查看 http://localhost/demo/test.php
会看到如下信息:
php-java-bridge config...
Java version=1.6.0_10
Java vendor=Sun Microsystems Inc.
OS=Windows Vista 6.0 on x86
