Question

我的servlet-context文件有

<beans:bean
class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <beans:property name="useNotAcceptableStatusCode"
        value="false" />
    <beans:property name="contentNegotiationManager">
        <beans:bean
            class="org.springframework.web.accept.ContentNegotiationManager">
            <beans:constructor-arg>
                <beans:bean
                    class="org.springframework.web.accept.PathExtensionContentNegotiationStrategy">
                    <beans:constructor-arg>
                        <beans:map>
                            <beans:entry key="html" value="text/html" />
                            <beans:entry key="json" value="application/json" />
                        </beans:map>
                    </beans:constructor-arg>
                </beans:bean>
            </beans:constructor-arg>
        </beans:bean>
    </beans:property>

    <beans:property name="viewResolvers">
        <beans:list>
            <beans:bean
                class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
            <beans:bean id="jspView"
                class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                <beans:property name="prefix" value="/WEB-INF/jsp/" />
                <beans:property name="suffix" value=".jsp" />
            </beans:bean>
        </beans:list>
    </beans:property>

    <beans:property name="defaultViews">
        <beans:list>
            <beans:bean
                class="org.springframework.web.servlet.view.json.MappingJackson2JsonView" />
        </beans:list>
    </beans:property>
</beans:bean>

我的控制器文件

@Controller("resources")
public class Resources {

     @RequestMapping(value = "/resources/{name}", method = RequestMethod.GET)
     public Map getResource(@PathVariable String name) {
        return new HashMap();
     }
}

但每当我尝试访问 /server/resources/myfilename.html

服务器抛出404说未找到 /server/WEB-INF/jsp/resources/myfilename.jsp 。但它应该使用BeanNameViewResolver加载 /server/WEB-INF/jsp/resources.jsp 。请帮忙。

Answer 1

你得到了什么：

Controller返回一个空视图名称，因此DefaultRequestToViewNameTranslator从servlet路径生成一个URI = path而没有斜杠和文件扩展名： resources / myfilename
BeanNameViewResolver尝试从名为 resources / myfilename 的上下文中获取View，似乎失败并链接到下一个ViewResolver
InternalResourceViewResolver返回JstlView指向jsp前缀+ viewName + suffix = /WEB-INF/jsp/resources/myfilename.jsp

所以BeanNameViewResolver似乎没有解析视图，InternalResourceViewResolver的返回是预期的。

你想要什么（我想）

您想要从默认视图名称中删除文件名，而不仅仅是扩展名。

实施RequestToViewNameTranslator并在DispatcherServlet上下文中声明名称 viewNameTranslator 。

例如：

public class StripFileNameViewNameTranslator extends DefaultRequestToViewNameTranslator {

    @Override
    protected String transformPath(String lookupPath) {
        String path = super.transformPath(lookupPath);
        return  StringUtils.substringBeforeLast(path, "/");
    }
}
