Spring XML View Resolver Conifguration

Question

我试图使用spring-mvc将一些模型数据输出到pdf.它不起作用,我想知道是否有人可以提供一些建议.

我有一个spring-servlet.xml文件,其中包含以下内容:

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="order" value="1"/>
    <property name="prefix" value="/WEB-INF/view/"/>
    <property name="suffix" value=".jsp"/>
</bean>

<bean id="xmlViewResolver" class="org.springframework.web.servlet.view.XmlViewResolver">
    <property name="order" value="2"/>
    <property name="location">
        <value>/WEB-INF/spring-pdf-views.xml</value>
    </property>
</bean>

在spring-pdf-views.xml文件中,我有:

<bean id="MyPDF" class="com.example.MyPDFView"/>

这是我的MyPDFView类:

public class MyPDFView extends AbstractPdfView {

    @Override
    protected void buildPdfDocument(Map<String, Object> model, Document document, PdfWriter writer, 
            HttpServletRequest request, HttpServletResponse response) throws Exception {

        @SuppressWarnings("unchecked")
        Map<String, String> data = (Map<String, String>) model.get("modelData");

        Table table = new Table(2);
        table.addCell("Date");
        table.addCell("Name");
        table.addCell(data.get("modelData.dateValue"));
        table.addCell(data.get("modelData.nameValue"));

        document.add(table);
    }
}

}

最后在我的控制器中我有:

@RequestMapping(value="/pdfInformation", method=RequestMethod.POST)
public ModelAndView showPDF(ModelMap model, PDFInfo pdfInfo, BindingResult result) {
        return new ModelAndView("MyPDF", model);
}

}

我在输出中看到的问题是它永远不会到达xmlViewResolver.它试图将MyPDF渲染为JSTL视图.这来自我的日志:

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="order" value="1"/>
    <property name="prefix" value="/WEB-INF/view/"/>
    <property name="suffix" value=".jsp"/>
</bean>

<bean id="xmlViewResolver" class="org.springframework.web.servlet.view.XmlViewResolver">
    <property name="order" value="2"/>
    <property name="location">
        <value>/WEB-INF/spring-pdf-views.xml</value>
    </property>
</bean>

someonme请帮忙,让我知道我错过了什么.提前致谢.

从Javadoc for InternalResourceViewResolver:

注意:链接ViewResolvers时,InternalResourceViewResolver始终需要为last,因为它将尝试解析任何视图名称,无论底层资源是否确实存在.

交换解析器的顺序.
