我有一个CFC脚本，它返回一个结构，转换成JSON格式。这是方法声明：

<CFFUNCTION name="getJSON" returntype="Struct" returnformat="JSON" output="no" access="remote">

JSON数据包含德语umlauts。第一个在这个位置：“行：1，列：745”

创建数据源时出错。InputStream不在UTF-8中

jsonUrl = getParam('JSON_URL', ReportParamArray);
inputStream = CreateObject("java", "java.net.URL").init(jsonUrl).openConnection().getInputStream();
jasperPrint = jasFillManager.fillReport(jasReport, parameters,
                CreateObject("java", "net.sf.jasperreports.engine.data.JsonDataSource").init(inputStream));

这是完整的堆栈跟踪：

我如何确保CFC返回有效的UTF-8含量？

在Leigh的帮助下，我解决了这个问题。

getInputStream（）

函数未使用UTF-8。即使我将默认文件编码设置为UTF-8，它也不起作用

为了确保报表生成器使用UTF-8，我重新创建了输入流，并在流程中应用了编码

jsonUrl = getParam('JSON_URL', ReportParamArray);

// Get the Input Stream
inputStream = CreateObject("java", "java.net.URL").init(jsonUrl).openConnection().getInputStream();

// Convert the stream to a byte array
bytes = CreateObject("java", "org.apache.commons.io.IOUtils").toByteArray(inputStream);

// Convert bytes to string
str = CreateObject("java", "java.lang.String").init(bytes);

// Create a new UTF-8 input stream
inputStreamUTF8 = CreateObject("java", "java.io.ByteArrayInputStream").init(str.getBytes("UTF-8"));

// Fill the report with our new input stream
jasperPrint = jasFillManager.fillReport(jasReport, parameters,
    CreateObject("java", "net.sf.jasperreports.engine.data.JsonDataSource").init(inputStreamUTF8));

就性能而言，这可能不是一个完美的解决方案，但它很有效，我躲过了编码的地狱。

您的内容数据来自哪里？很可能数据一开始就没有正确编码。换句话说，到底是什么操作报告响应不是UTF8？错误片段显示了ByteArrayInputStream错误，但没有显示在更广泛的代码中如何使用它。您可以发布完整的堆栈跟踪吗？我用jasperreports 6.1.0做了一个简单的测试。我通过调用cfc创建了一个数据源（如上所述）。返回的测试数据是您姓名中的字符。令人惊讶的是，我没有在这一行中得到错误：

ds=createObject（“java”、“net”、“net.sf.jasperreports.engine.data.JsonDataSource”）.init（inputStream）可能错误发生在jasFillManager实际使用数据源时，而不仅仅是在创建数据源时。所以我想看看完整的stack trace.BTW，这里是我在jasper 6.1.0中使用的测试代码。据我所见，错误是由jackson解析器iecom.fasterxml.jackson.core.json.UTF8StreamJsonParser抛出的。出现了一个快速搜索，这表明解析器使用BOM来检测编码。不确定如何/如果这适用于响应流。。。另外，我注意到您使用的是Lucee，而我使用的是ACF（行为可能有点不同）。我对jasperreports不太熟悉。也许以后我可以挖一个例子来测试“fill”方法。尝试重现错误。
