JasperReports API：调用JasperCompileManager.compileReport（String）方法引发了MalformedByteSequenceException异常 [英] JasperReports API: calling JasperCompileManager.compileReport (String) method raised the MalformedByteSequenceException exception

问题描述

public void openReport() {

    try {
        HashMap params = new HashMap();
        params.put("aapor", 19);

        JasperReport jasperReport1 = JasperCompileManager.compileReport("C:/Users/emidemi.emidemi-PC/Documents/NetBeansProjects/FleetManager/src/FleetManager/newReport5.jasper");
        JasperPrint jasperPrint1 = JasperFillManager.fillReport(jasperReport1, params, conn.getConn());

        JRViewer viewer = new JRViewer(jasperPrint1);

    } catch (Exception e) {
        System.out.println(e.getMessage());
    }
}

以上是我的脚本。

这是我的错误：

com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 1 of 1-byte UTF-8 sequence.
BUILD SUCCESSFUL (total time: 7 seconds)

有谁知道为什么会这样，如何解决？

Does anyone know why this is occurring and how to fix it?

推荐答案

这是字符编码的问题。您是否尝试在报告开头更改编码行？

It's a problem with the character codification. Have you tried changing the encoding line at the beginning of the report?

即。对于中欧字母，更改：

i.e. for central european alphabet, change:

<?xml version="1.0" encoding="UTF-8"?>

by

<?xml version="1.0" encoding="CP1250"?>

这里有一个不同的字符编码标准列表：
