Question

我正在开发一个Spring Boot应用程序，我试图使用XmlViewResolver使用itext从预定义的模板查看pdf。当我访问“ / welcome”和“ / invoice”时成功获取jsp页面，但是当我尝试“ / pdf”时失败。请让我知道怎么了。为什么pdf Bean无法正常工作？

白标错误页面

此应用程序没有针对/ error的显式映射，因此您将其视为备用。

发生意外错误（类型=未找到，状态= 404）。

/WEB-INF/jsp/pdf.jsp

下面是代码

@Controller
public class MainController {

@RequestMapping("/welcome")
public String hello(Model model) {
    model.addAttribute("msg", "XmlViewResolver Demo");
    return "success";
}

@RequestMapping("/invoice")
public String getInvoiceInfo() {
    return "invoice";
}

@RequestMapping("/pdf")
public String getPdfInfo() {
    return "pdf";
}
}

JspConfig.java

@Component
public class JspConfig {
@Bean
public ViewResolver internalResourceViewResolver() {
    InternalResourceViewResolver bean = new InternalResourceViewResolver();
    bean.setViewClass(JstlView.class);
    bean.setPrefix("/WEB-INF/jsp/");
    bean.setSuffix(".jsp");
    bean.setOrder(2);
    return bean;
}
}

XmlConfig.java

@Configuration
public class XmlConfig {
@Bean
public XmlViewResolver xmlViewResolver() {
    XmlViewResolver resolver = new XmlViewResolver();
    Resource resource = new ClassPathResource("xml/user-view.xml");
    resolver.setLocation(resource);
    resolver.setOrder(1);
    return resolver;
}
}

user-view.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<bean id="invoice" class="org.springframework.web.servlet.view.JstlView">
    <property name="url" value="WEB-INF/template/invoice.jsp" />
</bean>

<bean id="pdf" class="com.example.config.PdfView">
    <property name="url" value="WEB-INF/template/invoiceTemplate.pdf" />
</bean>

PdfView.java

import com.lowagie.text.pdf.PdfStamper;

public class PdfView extends AbstractPdfStamperView implements MessageSourceAware {

@Override
protected void mergePdfDocument(Map<String, Object> model, PdfStamper   stamper, HttpServletRequest request, response) throws Exception {

    stamper.setFormFlattening(true);
    String customerName = (String) model.get("customerName");
    stamper.getAcroFields().setField("name", customerName);
    stamper.close();
}
}

Spring Boot JSP页面有效，但XmlViewResolver不起作用
