Question

我是thymeleaf的新手。我想在我的spring mvc项目中同时使用jsp和thymeleaf，一切看起来都很完美，但由于＆＃34;请求资源不可用而导致404例外。＃34; 。请帮忙。

404 exception!

我的配置是这样的：

        model.addAttribute("name", name);

        return "mythymeleaf";
    }

    @RequestMapping(value="/decideView",params="jspbtn",method=RequestMethod.GET)

项目结构：

Project Structure

Answer 1

你有几个拼写错误

您的项目结构显示jsp文件夹名称位于views/jsp下，但在前缀中您只提到了view。所以改为
404说/WEB-INF/view/jsp/mythymeleaf.jsp不可用.Ofcourse 是。它出现在/WEB-INF/views/thymeleaf/mythymeleaf.jsp下
- 它正在使用JSP，因为它使用InternalResourceViewResolver而不是ThymeleafViewResolver。

Answer 2

我认为两个解析器的路径（前缀）冲突，因为其中一个包含另一个（/WEB-INF/view包含/WEB-INF/view/jsp）。尝试将您的* .jsp视图移动到另一个目录，例如/WEB-INF/jsp，更改下面的internalViewResolver并且应该可以工作。

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

观看示例：

/WEB-INF/view/thymeleaf/mythymeleaf.html
/WEB-INF/jsp/index.jsp
/WEB-INF/jsp/myjspview.jsp

现在可以使用的请求映射：

@RequestMapping("/th")
public String th() {
    return "thymeleaf/mythymeleaf";
}

@RequestMapping("/jsp")
public String jsp() {
    return "index";
}

@RequestMapping("/jsp2")
public String jsp2() {
    return "myjspview";
}

另一种看起来更好且在下工作的配置。我已将internalViewResolver的前缀更改为/WEB-INF/view/。请注意，重新定位器的前缀相同，但ThymeleafViewResolver将viewNames定义为thymeleaf/*，因此/WEB-INF/view/thymeleaf/以下的所有内容都将由Thymeleaf解析。

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

未更改：

<bean id="templateResolver"
    class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <property name="prefix" value="/WEB-INF/view/" />
    <property name="suffix" value=".html" />
    <property name="templateMode" value="HTML5" />
    <property name="cacheable" value="true" />
</bean>

查看：

/WEB-INF/view/thymeleaf/mythymeleaf.html
/WEB-INF/view/index.jsp
/WEB-INF/view/myjspview.jsp

如何在同一个春季mvc项目中使用jsp和thymeleaf
