可能有帮助关于SpringMVC和JasperReport的集成的配置问题-程序员问答-好库编程网
您好，欢迎光临！
拒绝没有做过实际开发的朋友复制网上搜索的答案，谢谢。
Spring配置里加：
&&&&&bean&class="org.springframework.web.servlet.view.XmlViewResolver"&
&&&&&&&&&property&name="location"&value="WEB-INF/jasper-views.xml"/&
&property&name="order"&value="0"/&
&&&&&/bean&&
jasper-views.xml文件：
&&&&&bean&id="htmlReport"&&&&&&&&&&&&&&&class="org.springframework.web.servlet.view.jasperreports.JasperReportsPdfView"&
&&&&&&&&&&&property&name="url"&value="classpath:reportTest.jrxml"/&
&&&&&/bean&
Controller里：
&&&&@Controller
&&&&public&class&BloodApplicationController&{
&&&&&&&&@RequestMapping(value="/printApplicationForm")
public&ModelAndView&printApplicationForm(HttpServletRequest&request,&&&&&HttpServletResponse&response){
("打印申请单");
Map&String,&Object&&model&=&new&HashMap&String,&Object&();
model.put(JasperReportsMultiFormatView.DEFAULT_FORMAT_KEY,&"pdf");
return&new&ModelAndView("htmlReport",&model);
什么问题？错误信息
这么看，不好看。
你想问什么问题？
引用&1&楼&fangmingshijie&的回复:什么问题？错误信息
引用&2&楼&k_scott&的回复:这么看，不好看。
引用&3&楼&peng_hao1988&的回复:你想问什么问题？
对不起，没说清楚。
我想点击打印按钮然后通过Controller调用Service取出数据，然后跳到jasper文件，生成html预览，然后可以通过预览html打印。
我是这样配置的，麻烦大家帮忙看看有什么问题。
下载ireport，可视化的
引用&5&楼&fangmingshijie&的回复:下载ireport，可视化的
我现在用的就是ireport，然后根据生成的jrxml编译出jasper文件。
问题是集成到SpringMVC里就是显示不出来内容。
显示不出来，报什么错？http://blog.csdn.net/jia20003/article/details/8471169
引用&7&楼&fangmingshijie&的回复:显示不出来，报什么错？http://blog.csdn.net/jia20003/article/details/8471169
你发的链接我看过，但是当时没仔细看，刚才又看了一遍，对比之下配置上我没觉得有什么问题。
现在是显示不出打印内容，在ireport工具里可以打印出来，但是通过程序打印不出来，后台无报错信息。
如果你有这方面的开发经验，麻烦加下QQ聊好吗？解决了我再加分。
麻烦有这方面开发经验的朋友帮我解决，先谢谢了！
只能自己再顶下了，继续等待。
该回复于 13:23:34被管理员删除
管理员什么意思啊，有本事删帖，怎么没本事帮我解决这个问题呢？！！
只能自己再顶下了，继续等待。&
只能自己再顶下了，继续等待。&&
等答案。。。
我也在整。没整出结果来。在SpringMVC中都没有显示内容。奇怪啊。。。。
楼住整出来了没。现在我也在搞都找了三天资料了。都没有能用的。。。求分享！！
同求啊，跟楼主一样的情况，哎，哪位大侠指导一下撒！！！！
这么长时间过去了，&还没有回答啊
那么久还没人解决?
设计静态报表模板时输出预览时总是空白页。
解决办法：可以通过设置报表属性中的“当没有数据时的显示方式”为：除detail外的所有地方。
楼主这问题解决了吗。。。配置数据源的方法我解决了。。
其实感觉可以直接用finereport开发在构建SPRING3.2 MVC 中出现的问题
&!-- 扩展名至mimeType的映射,即 /blog.json =& application/json --&
&property name="mediaTypes"&
&entry key="html" value="text/html" /&
&entry key="pdf" value="application/pdf" /&
&entry key="xsl" value="application/vnd.ms-excel" /&
&entry key="xml" value="application/xml" /&
&entry key="json" value="application/json" /&
&/property&
我一加上上面的这个东西我的项目在访问的时候报错 错误信息是

java.lang.ClassCastException: java.lang.String cannot be cast to org.springframework.http.MediaType&
spring3.2的bug
ContentNegotiatingViewResolver
public void setMediaTypes(Map&String, String& mediaTypes)
& {
&&& if (mediaTypes != null)
&&&&& ManagerFactoryBean.getMediaTypes().putAll(mediaTypes);
& }
MappingMediaTypeFileExtensionResolver构造器：
public MappingMediaTypeFileExtensionResolver(Map&String, MediaType& mediaTypes)
& {
&&& if (mediaTypes != null)
&&&&& for (Map.Entry entries : mediaTypes.entrySet()) {
&&&&&&& String extension = ((String)entries.getKey()).toLowerCase(Locale.ENGLISH);
&&&&&&& MediaType mediaType = (MediaType)entries.getValue();
&&&&&&& addMapping(extension, mediaType);
&&&&& }
& }
Map的value是不兼容的。
而且spring3.2开始不推荐使用setMediaTypes等直接设置这些数据， 而是通过ContentNegotiationManager（ContentNegotiationManagerFactoryBean）
如
&bean class="ContentNegotiatingViewResolver"&
&& &property name="contentNegotiationManager"&
&&&&&&&& &bean class="ContentNegotiationManagerFactoryBean"&
&&&&&&&&&&&& &property name="mediaTypes"&
&&&&&&&&&&&&&&&&&& &props&注入即可
&&&&&&&&&&&& &/property&
&&&&&&&& &/bean&
&& &/property&
&/bean&
