在java中没有得到这样的方法错误 [英] getting no such method error in java

问题描述

我收到以下错误，如下所示

I am getting the following error as shown below

java.lang.NoSuchMethodError: org.apache.poi.hssf.usermodel.HSSFSheet.addMergedRegion(Lorg/apache/poi/hssf/util/Region;)I
        at net.sf.jasperreports.engine.export.JRXlsExporter.createMergeRegion(JRXlsExporter.java:440)
        at net.sf.jasperreports.engine.export.JRXlsExporter.initCreateCell(JRXlsExporter.java:419)
        at net.sf.jasperreports.engine.export.JRXlsExporter.createTextCell(JRXlsExporter.java:381)
        at net.sf.jasperreports.engine.export.JRXlsExporter.exportText(JRXlsExporter.java:314)
        at net.sf.jasperreports.engine.export.JRXlsAbstractExporter.exportPage(JRXlsAbstractExporter.java:381)

我正在使用下面的poi jars，如课程路径中所示，并且也使用jasperreports 1.2.5 jar，请告知我已将poi jars从2.5升级到3，所以请告知我是否还需要升级jasperreports-1.2.5.jar与最新的poi jars保持同步

i am using the below poi jars as shown in the class path and also jasperreports 1.2.5 jar please advise i have upgraded poi jars from 2.5 to 3 so please advise do i need to upgrade jasperreports-1.2.5.jar also to be in synch with the latest poi jars

<classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/poi-3.5-FINAL.jar"/>
    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/poi-contrib-3.5-final.jar"/>
    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/poi-scratchpad-3.5-FINAL.jar"/>
    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/dom4j-1.6.1.jar"/>  
    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/poi-ooxml-3.5-FINAL.jar"/>

    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/poi-ooxml-schemas-3.6.jar"/>
    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/xmlbeans-2.3.0.jar"/>
    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/poi-ooxml-schemas-3.10-FINAL.jar"/>
    <classpathentry exported="true" kind="lib" path="thirdparty/POI-3.5/jsr173_1.0_api.jar"/>

尽管我做了一些分析，发现此网址为http://community.jaspersoft.com/questions/531433/save-excel-jasperviewer 这表明随着poi的渐变，我也应该升级碧玉罐子

although i have done some analysis and found this url http://community.jaspersoft.com/questions/531433/save-excel-jasperviewer which suggest with poi up gradation i should upgrade my jasper jars also

对于jasper报表，我还没有升级，我正在使用jasper报表1.2.5 jar，我也应该升级吗，伙计，请告知

for jasper reports i have not upgraded i am using jasper reports 1.2.5 jar should i upgrade that also , folks please advise

推荐答案

java.lang.NoSuchMethodError是未使用正确版本的库时的典型错误.

java.lang.NoSuchMethodError is typical error when not using correct version of libraries.

Jasper报表使用多个库，这些库可在其发行版(位于文件夹lib中)中找到，它们都应包含在classpath

Jasper report uses multiple libraries which can be found in its distribution (in folder lib), they should all be included in classpath

碧玉报告版本

如果您使用的是Jasper报告1.2.5，则这是它的版本

If you are using Jasper reports 1.2.5 this is its release Jasper report v 1.2.5. You will find correct libraries to include in your classpath in folder lib.

但是，毫无疑问最好升级到最新版本(发布此答案6.2.0时)，特别是如果您需要导出到xlxs，ooxml，XSSF，则将其在1.2.5中不受支持.

However there is no doubt that is better to upgrade to latest version (when posted this answer 6.2.0), specially if you need to export to xlxs, ooxml, XSSF, this it not supported in 1.2.5.

注意:碧玉报告已更改，文件格式定义从较新版本的DTD更改为XSD模式，因此您可能需要在.jrxml中更改标头(或使用旧的.jrxml编译器)

Note: jasper report has change is file format definition from DTD to XSD schema in newer version so you may need to change your headers in .jrxml (or use old .jrxml compiler)
