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"请求资源不可用而导致404例外。#34; 。请帮忙。
我的配置是这样的:
弹簧Servlet的Config.xml中

项目结构:
答案 0 :(得分:0)
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
InternalResourceViewResolver
而不是ThymeleafViewResolver
。答案 1 :(得分:0)
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
