php - Jasper 与 php 帮助放置从 ireport/modules/ext 复制的所有 jar 文件的位置

Question

我是 jasperreport 的新手。

1. 谁能帮我从 ireport/modules/ext 复制 jar 文件的位置？
2. 只有 ireport/modules/ext 中的 jar 文件就足够了吗？
3. 如何与php连接。

谁能帮我解决这个问题

Answer 1

1. 谁能帮我从 ireport/modules/ext 复制 jar 文件的位置？将只有 ir 中的 jar 文件

您必须将其复制到您的 java_home 目录。我使用的是 windows7，所以在我的情况下它将是 C:\Program Files\Java\jre7\lib\ext。确保你已经为你的 java_home 设置了类路径。（我希望你知道怎么做）

1. 只有 ireport/modules/ext 中的 jar 文件就足够了吗？

是的，这对你有用

1. 如何与php连接。

浏览下面给出的示例

 include('../includes/javabridge.php');
java_set_file_encoding("UTF-8");

// Load the Jasper Report

$jrxml = new java("net.sf.jasperreports.engine.xml.JRXmlLoader");
$jasperTemplate = $jrxml->load(realpath("customer.jrxml"));

// Load the Query 

$_Query = new java("net.sf.jasperreports.engine.design.JRDesignQuery");
$_Query->setText("select * FROM customers");
$jasperTemplate->setQuery($_Query);

// Compile the Report after including the Query

$compile = new JavaClass("net.sf.jasperreports.engine.JasperCompileManager");
$report = $compile->compileReport($jasperTemplate);

// Connect to the database

$class = new JavaClass("java.lang.Class");
$class->forName("com.mysql.jdbc.Driver");
$mysqlDriver = new JavaClass("java.sql.DriverManager");
$conn = $mysqlDriver->getConnection("jdbc:mysql://localhost:3309/dbcustomer?user=root&password=");

// Now Fill the Report 
$jasperFill = new JavaClass("net.sf.jasperreports.engine.JasperFillManager");
$params = new Java("java.util.HashMap");
$params->put("title", "Customer");
$jasperPrint = $jasperFill->fillReport($report, $params, $conn);

// Now Export the Report to desired format 

$jasperExport = new java("net.sf.jasperreports.engine.JRExporter");

    // Change here to generate report in pdf , excel,docx etc.. 
$Format = "pdf";

switch ($Format)
