在搭建項(xiàng)目過程中順利完成，（如何搭建詳見《看透sPRingMvc源代碼分析與實(shí)現(xiàn)》這本書中第八章）.啟動(dòng)之后遇到的問題如下：

項(xiàng)目可以成功啟動(dòng)，但是訪問URL時(shí)后臺(tái)報(bào)錯(cuò)

Configuration problem: Cannot locate BeanDefinitionParser for element [view-resolvers]

出現(xiàn)這個(gè)問題的原因是項(xiàng)目lib里的spring-webmvc-4.2.5.RELEASE.之前用的是spring-webmvc-3.2.0.RELEASE這個(gè)版本，由于版本低問題導(dǎo)致xml中schema找不到[view-resolvers]，大家有時(shí)間可以去看看，3.2.0.RELEASE這個(gè)版本的所有xsd均沒有[view-resolvers]，4.2.5.RELEASE這個(gè)版本spring-mvc-4.2.xsd和spring-mvc-4.1.xsd這兩個(gè)有

其中的[view-resolvers]在配置文件中配置：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"               xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="  http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd  http://www.springframework.org/schema/util  http://www.springframework.org/schema/util/spring-util-4.2.xsd  http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context-4.2.xsd  http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd ">   <mvc:annotation-driven></mvc:annotation-driven>  <context:component-scan base-package="com.game"></context:component-scan>   <!-- <mvc:view-resolvers>  <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="WEB-INF/views/jsp" p:suffix=".jsp"></bean>  </mvc:view-resolvers> --> <mvc:view-resolvers> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/views/" p:suffix=".jsp"></bean>  </mvc:view-resolvers>  <!--  <bean id = "helloworld" class="com.game.controller.Helloworld">  </bean>  --></beans>

---------------------------------------------------------------------------------------------------------------

由于 <mvc:view-resolvers>需要較高的jar版本，配置起來需要好多新的jar，所以我配置viewresolver用的另一種：

<!-- 對(duì)轉(zhuǎn)向頁面的路徑解析。prefix：前綴， suffix：后綴 -->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/views/" p:suffix=".jsp" /> 

用這個(gè)替換標(biāo)紅的，同樣可以實(shí)現(xiàn)。

這個(gè)有一個(gè)問題是在controler中，showArticle方法的articleId一直取不到值。不知道是不是配置中沒用<mvc:view-resolvers>   導(dǎo)致的，覺得原書中能取到也挺不可思議的

@RequestMapping(value={"/articles/{articleId}/comment"})public String doComment(@PathVariable String articleId,RedirectAttributes attributes,Model model)throws Exception{String comment=(String) model.asMap().get("comment");comment=new String (comment.getBytes("UTF-8"));attributes.addFlashAttribute("comment", (String) model.asMap().get("comment"));model.addAttribute("articleId", articleId);return "redirect:/showArticle";}

@RequestMapping(value={"/showArticle"},method={RequestMethod.GET})public String showArticle(Model model,sessionStatus sessionStatus) throws Exception{String articleId =(String)model.asMap().get("articleId");model.addAttribute("articleTitle", articleId+"號(hào)文章標(biāo)題");model.addAttribute("article",articleId+"號(hào)文章內(nèi)容");sessionStatus.setComplete();return "article";}
