指定每个控制器要使用哪个ViewResolver? [英] Specify which ViewResolver to use per Controller?

问题描述

我的spring应用程序中有一个freemarker viewresolver:

I have a freemarker viewresolver in my spring application:

<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

在我的控制器方法中，我可以返回我的自由标记模板的名称:

In my controller methods i can return the name of my freemarker template:

return "timeline";

工作正常.

现在，我已经创建了一种新的模板语言，并且我希望一些控制器使用此自定义模板语言.所以我创建了一个CustomViewResolver.

Now i've created a new template language and i want a few controllers to use this custom template language. So i created a CustomViewResolver.

<bean id="viewResolver" class="org.CustomViewResolver">

现在我有2个视图解析器，一个是自由标记，另一个是我的自定义视图.

Now i have 2 view resolvers, a freemarker one and my custom one.

如何指定哪个控制器应使用哪个ViewResolver?

How can i specify which ViewResolver should be used by which controller?

因为我的后端将使用freemarker，而我的前端将使用自定义标记.

Cause my backend will use freemarker and my frontend the custom one.

推荐答案

您可以按照以下示例进行尝试:

You could try something along the lines of the following example:

文件夹和文件结构

webapp
   WEB-INF
       dispatcher-servlet.xml
       jsp
         bar
           bar-baz.jsp
         foo
           foo-fro.jsp

dispatcher-servlet.xml

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="prefix" value="/WEB-INF/jsp/bar/" />
  <property name="suffix" value=".jsp"/>
  <property name="viewNames" value="bar-*"/>
</bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="prefix" value="/WEB-INF/jsp/foo/" />
  <property name="suffix" value=".jsp"/>
  <property name="viewNames" value="foo-*"/>
</bean>

控制器

@RequestMapping(value="/bar")
public String bar() { return "bar-baz"; }

@RequestMapping(value="/foo")
public String foo() { return "foo-fro"; }

您将利用框架提供的视图名称模式匹配.如果遇到问题，可以尝试为视图解析器设置其他order属性，以控制解析器尝试查找请求视图的顺序.您将自定义视图解析器放在顶部(最低顺序)，如果自定义解析器失败，则尝试其他视图解析器.

You will be taking advantage of the view name pattern-matching offered by the framework. If you run into problems, you can try setting an additional order property for the view resolvers to control the order in which the resolvers should attempt to locate views for a request. You would put your custom view resolver at the top (lowest order) and try others if the custom resolver fails.
