我的情况与案件非常相似: Jasper Report with Struts2 Framework
一切正常并生成PDF文件。代码类似,配置 struts.xml 类似,或者我们可以说它是相同的。
我尝试以 RTF格式生成报告。这很简单,正确?只需替换 struts.xml 中的一行 - &gt; <param name="format">RTF</param>
。
格式 - 应生成报告的格式。有效值可以在JasperReportConstants中找到。
在JasperReportConstants下有“FORMAT_RTF”。这意味着值为“RTF”。没有其他的。或者......我错过了什么吗?
系统会生成 pdf-document ,其扩展名为“ rtf ”,而不是真正的 RTF格式文档。
有什么问题?我错过了什么?
答案 0 :(得分:0)
我希望您使用正确且兼容的 itext 和 jasper Repot。
<param name="format">RTF</param>
是RTF的唯一更改。
这是一个有效的例子
<package name="default" namespace="/" extends="jasperreports-default">
<action name="myJasperTest" class="com.common.JasperAction">
<result name="success" type="jasper">
<param name="location">/jasper/our_compiled_template.jasper</param>
<param name="dataSource">myList</param>
<param name="format">RTF</param>
</result>
</action>
</package>
如果您使用与Jasper Report with Struts2 Framework相同的代码,则需要更改代码。因为在该代码中,它们以pdf格式导出。
您可以使用
try {
JasperCompileManager.compileReportToFile(
"C:\\Users\\Parth\\workspace1\\serializ\\jasper/our_jasper_template.jrxml",
"H:\\jasper/our_compiled_template.jasper");
} catch (Exception e) {
e.printStackTrace();
return ERROR;
}
