每当csv和excel导出正常工作但pdf导出不工作时，我正在使用带有iReport 5.5.0的grails 2.3.2和jasperreport 1.8.0，但pdf导出不起作用，我的 Controller 代码为:

def reportWithOutComma = params.summaryReportDataTable.split(",")           
        def inst = Institution.get(session.institutionid.toLong())          
        def result = [:]
        result.data = []
        for(int i = 0;i<reportWithOutComma.size();i+=7){
            def spaceReplacedData = reportWithOutComma.toString().replace('&nbsp;',' ')           
            def name = reportWithOutComma[i].decodeHTML().toString()
            def index1  = name.indexOf("(")
            def stdNames = name.substring(0,index1)           
            result.data << [StudentName:stdNames,
                           TotalDays:reportWithOutComma[i+1].decodeHTML(),
                           Holidays:reportWithOutComma[i+2].decodeHTML(),
                           LeaveDays:reportWithOutComma[i+3].decodeHTML(),
                           AbsentDays:reportWithOutComma[i+4].decodeHTML(),
                           LateMins:reportWithOutComma[i+5].decodeHTML(),
                           EarlyMins:reportWithOutComma[i+6].decodeHTML()]
        }
        params.InstitutionName = inst.name           
        params._format = "PDF"
        params._file = "summaryReport" // filename of xml file           
        def report = jasperService.buildReportDefinition(params, request.getLocale(),result)           
        generateReport(report)           
    }
generateReport包含: 
def generateReport = { reportDef ->           
        if (!reportDef.fileFormat.inline && !reportDef.parameters._inline) {           
            response.setHeader("Content-Disposition", "inline; filename=\"${reportDef.parameters._name ?: reportDef.name}.${reportDef.fileFormat.extension}\"");           
            response.setHeader("Content-Type", "${reportDef.fileFormat.mimeTyp}");           
            response.contentType = reportDef.fileFormat.mimeTyp           
            response.characterEncoding = "UTF-8"           
            response.outputStream << reportDef.contentStream.toByteArray()
        } else {}           
    }

我有由iReport创建的xml文件是: 
<?xml version="1.0" encoding="UTF-8"?>

并在pdf导出期间显示以下错误: 
URI
/sAttend/report/summaryReport
Class
java.lang.NoSuchMethodError
Message
com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V

我该如何解决这个问题，请帮忙。

最佳答案

如果运行grails dependency-report，您可能会在报告中看到itext的2个版本。 Grails用于生成文档的文档可能存在冲突。尝试通过修改BuildConfig以排除Grails所使用的BuildConfig来排除它:

inherits("global") {
    excludes "itext"
}

关于xml - PDF导出在Grails 2.3.2中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23605913/
