PHP调用lucene(java类)的问题
最近要用php+lucene来搭一个检索页面,基本思路是让用户在php输入信息,然后php页面调用lucene进行搜索并返回结果给php,php将结果呈现给用户。
目前环境winXP+PHP5.3+apache2.2+mysql,lucene版本3.5
我的想法是:先用java写了一个调用lucene API的类,实现了基本的检索功能。然后用php调用这个java类来进行检索。
查了下相关文档,php5已经没有php_java.dll扩展,要使用php_java_bridge。
于是下了php_java_bridge5.4 ,照着网上搜到的资料,安装配置基本成功。测试时:
1、可以调用java的内置类。
2、自定义java类(如果只使用了java内置类),编译成class文件后打包成jar文件,用java_require("...")导入后可以调用自定义类。
但现在的问题是:
如果自定义java类中,import了lucene的类(这正是我目前的做法),则在php中调用此java类时会失败,查看javaBridge.jar的日志文件vmbridge.log,错误主要类似:
java.lang.ClassNotFoundException: Unresolved external reference: java.lang.NoClassDefFoundError: org/apache/lucene/store/Directory. -- Unable to call constructor
个人理解似乎是找不到lucene API中的类,导致无法创建对象。
现在能想到的就是直接用php来调用lucene的API接口,不知道可行否,但这样感觉比较麻烦。
本人比较菜,php调用java类来协调工作的机制我不是很清楚,郁闷了一整天了,求指点好的解决方案。。。
回复讨论(解决方案)
可以走http。调用java的接口返回json数据。然后php做相应的展现。没有必要通过扩展和java协作
主贴的情况有所进展,我将lucene.jar一起打包后,就不会出现上面的问题。
但在php里调用自定义类的方法来检索文档,似乎无法命中。。。代码类似:
$lucene = new Java("testLucene.TestLucene");
echo 'path='.$lucene->search(new Java("java.lang.String","美"),new Java("java.lang.String","D:/test/index/"));
?>
同样的代码(也是实例化自定义类后调用search方法)在java写的测试类中就可以正确检索到最匹配“美”字的文档。。。

终于等到回复了,先感谢下~
可以说的详细些或者给个简单的示例吗?
我也遇到这问题了,楼主或者其他人如果有解决办法 能否联系一下我啊 QQ784718085 或者发邮件也行

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.
