Spring XML View解析器配置 [英] Spring XML View Resolver Configuration

问题描述

我正在尝试使用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.

I am trying to output some model data to a pdf using spring-mvc. It is not working and I was wondering if someone could offer some advice.

我有一个spring-servlet.xml文件，其中包含以下内容:

I have a spring-servlet.xml file that includes the following:

<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，我具有以下内容:

In the spring-pdf-views.xml file I have this:

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

这是我的MyPDFView类:

This is my MyPDFView class:

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，我拥有:

Finally in my controller I have:

@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呈现为JSTL视图.这是从我的日志中获得的:

The problem I am seeing in the output is that it never gets to the xmlViewResolver. It is trying to render the MyPDF as a JSTL View. This is from my logs:

org.springframework.web.servlet.DispatcherServlet-呈现视图[org.springframework.web.servlet.view.JstlView:名称为'MyPDF';名为'spring'的DispatcherServlet中的URL [/WEB-INF/view/MyPDF.jsp]]

org.springframework.web.servlet.DispatcherServlet - Rendering view [org.springframework.web.servlet.view.JstlView: name 'MyPDF'; URL [/WEB-INF/view/MyPDF.jsp]] in DispatcherServlet with name 'spring'

我想念什么?

推荐答案

来自InternalResourceViewResolver的Javadoc :

注意:当链接ViewResolvers时，一个InternalResourceViewResolver总是需要最后一个，因为它将尝试解析任何视图名称，无论基础资源是否实际存在.

Note: When chaining ViewResolvers, an InternalResourceViewResolver always needs to be last, as it will attempt to resolve any view name, no matter whether the underlying resource actually exists.

交换您的解析器顺序.
