有关php调用lucene(JAVA)代码的问题
最近想使用网页显示Lucene搜索的结果,网上说用Php和javabridge可以,但是,我使用javabridge里面的example或者自己写的类都不行。
apache2.2+php5+mysql
现在是可以调用java自己的类如java.lang.String,但是自己写的不行啊。。。而且javabridge里面有一个例子是这样的:
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --><?php include_once ("java/Java.inc"); java_autoload("lucene.jar"); use java\lang\System as SYS; use java\io as IO; use java\util as Util; use org\apache\lucene as Lucene; try { echo "indexing ... "; /* create the index files in the tmp dir */ $tmp = create_index_dir(); $analyzer = new Lucene\analysis\standard\StandardAnalyzer(); $writer = new Lucene\index\IndexWriter($tmp, $analyzer, true); $file = new IO\File(getcwd()); $files = $file->listFiles(); assert (!java_is_null($files)); foreach($files as $f) { $doc = new Lucene\document\Document(); $doc->add(new Lucene\document\Field( "name", $f->getName(), Lucene\document\Field::type("Store")->YES, Lucene\document\Field::type("Index")->UN_TOKENIZED)); $writer->addDocument($doc); } ................ ................ ................
但是输出是这个
Warning: Unexpected character in input: '\' (ASCII=92) state=0 in C:\AppServ\www\test.php on line 5
Parse error: syntax error, unexpected T_STRING, expecting T_AS or T_PAAMAYIM_NEKUDOTAYIM or ';' in C:\AppServ\www\test.php on line 5
貌似php没有use这个用法啊。。。?
如果用java_require("lucene.jar");又说java_require什么不支持了。。。
大家路过帮帮忙吧。。。谢谢了
------解决方案--------------------
您的 php 版本太低了,尚不支持命名空间
------解决方案--------------------
环境有配置好吗。。。
编写一个简单的php测试一下。。。
$str = new java("java.lang.String", "hello");
echo $str;
------解决方案--------------------
这个问题好像我也遇到过,不过到现在也没解决
------解决方案--------------------
楼上是不是灌水啊,还弄个好像遇到过?我是真的遇到过,到现在还没解决的呢!
------解决方案--------------------
自己写个helloworld打包成jar 放到JavaBridge/WEB-INF/lib/下面 重启下jdk
然后在php里面 $helloworld=new Java("helloworld"); 试试看
我这没问题的

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

Java's platform independence means that the code written can run on any platform with JVM installed without modification. 1) Java source code is compiled into bytecode, 2) Bytecode is interpreted and executed by the JVM, 3) The JVM provides memory management and garbage collection functions to ensure that the program runs on different operating systems.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.
