從PHP傳遞數組數據到JasperReports（使用PHP/JavaBridge）

Question

我正在嘗試從php腳本創建pdf。我有JasperReports & PHP/JavaBridge啓動並運行，它在發送字符串&整數作爲參數時創建pdf文件。

我使用了Jasper Reports and PHP & Bullet-Proof Jasper Reports and PHP的指南來幫助設置PHP/JavaBridge和Jasper報告。

這是我的PHP腳本現在的樣子（非常相似，從前面提到的指南中的例子）：

<?php 

/** 
* see if the java extension was loaded. 
*/ 
function checkJavaExtension() 
{ 
    if(!extension_loaded('java')) 
    { 
     $sapi_type = php_sapi_name(); 
     $port = (isset($_SERVER['SERVER_PORT']) && (($_SERVER['SERVER_PORT'])>1024)) ? $_SERVER['SERVER_PORT'] : '8080'; 
     if ($sapi_type == "cgi" || $sapi_type == "cgi-fcgi" || $sapi_type == "cli") 
     { 
      if(!(PHP_SHLIB_SUFFIX=="so" && @dl('java.so'))&&!(PHP_SHLIB_SUFFIX=="dll" && @dl('php_java.dll'))&&!(@include_once("java/Java.inc"))&&!(require_once("http://127.0.0.1:$port/java/Java.inc"))) 
      { 
       return "java extension not installed."; 
      } 
     } 
     else 
     { 
      if(!(@include_once("java/Java.inc"))) 
      { 
       require_once("http://127.0.0.1:$port/java/Java.inc"); 
      } 
     } 
    } 
    if(!function_exists("java_get_server_name")) 
    { 
     return "The loaded java extension is not the PHP/Java Bridge"; 
    } 

    return true; 
} 

/** 
* convert a php value to a java one... 
* @param string $value 
* @param string $className 
* @returns boolean success 
*/ 
function convertValue($value, $className) 
{ 
    // if we are a string, just use the normal conversion 
    // methods from the java extension... 
    try 
    { 
     if ($className == 'java.lang.String') 
     { 
      $temp = new Java('java.lang.String', $value); 
      return $temp; 
     } 
     else if ($className == 'java.lang.Boolean' || 
      $className == 'java.lang.Integer' || 
      $className == 'java.lang.Long' || 
      $className == 'java.lang.Short' || 
      $className == 'java.lang.Double' || 
      $className == 'java.math.BigDecimal') 
     { 
      $temp = new Java($className, $value); 
      return $temp; 
     } 
     else if ($className == 'java.sql.Timestamp' || 
      $className == 'java.sql.Time') 
     { 
      $temp = new Java($className); 
      $javaObject = $temp->valueOf($value); 
      return $javaObject; 
     } 
    } 
    catch (Exception $err) 
    { 
     echo ( 'unable to convert value, ' . $value . 
       ' could not be converted to ' . $className); 
     return false; 
    } 

    echo ( 'unable to convert value, class name '.$className. 
      ' not recognised'); 
    return false; 
} 



if (true == checkJavaExtension()) { 
    echo 'java extension is loaded!!'; 
} 

$compileManager = new JavaClass("net.sf.jasperreports.engine.JasperCompileManager"); 
$report = $compileManager->compileReport(realpath("test.jrxml")); 

$fillManager = new JavaClass("net.sf.jasperreports.engine.JasperFillManager"); 

$params = new Java("java.util.HashMap"); 
$params->put("text", "This is a text"); 
$params->put("report_id", 2); 

$emptyDataSource = new Java("net.sf.jasperreports.engine.JREmptyDataSource"); 
$jasperPrint = $fillManager->fillReport($report, $params, $emptyDataSource); 

$outputPath = realpath(".")."/"."output.pdf"; 

$exportManager = new JavaClass("net.sf.jasperreports.engine.JasperExportManager"); 
$exportManager->exportReportToPdfFile($jasperPrint, $outputPath); 

header("Content-type: application/pdf"); 
readfile($outputPath); 

unlink($outputPath); 

?> 

上述工程的代碼，但我想用一個PHP數組作爲參數爲我的jrxml文件。什麼是最好的解決方案呢？

我想我可能必須創建一個java.util.List類，從我的PHP數組中設置數據作爲列表項，並將其作爲參數發送給我的jrxml文件，但我無法獲取這工作。

另一方面，這可能是非常錯誤的，因爲這對我來說都很新穎：\我感謝所有我能得到的幫助！ :)

林不知道我明白，但如果你有值的數組，如{id => 1，name =>'fubar'，something =>'blala'。試試這個：

$map = new Java("java.util.HashMap"); 
foreach ($array as $key=>$value){ 
    $map->put($key,$value); 
} 
$Jfm = new Java("net.sf.jasperreports.engine.JasperFillManager"); 
$this->FillReport = $Jfm->fillReport($this->CompileReport, $map, $this->DbConnect);
