Summary of view Resolver in Spring 3 MVC

The following is a summary of view Resolver in Spring 3 MVC:

1 internalresourceviewresolver

This is the most commonly used method for splicing returned views, for example:

<Bean

Class = "org. springframework. Web. servlet. MVC. Support. controllerclassnamehandlermapping"/>

<! -- Register the bean -->

<Bean class = "com. mkyong. Common. Controller. welcomecontroller"/>

<Bean id = "viewresolver"

Class = "org. springframework. Web. servlet. View. internalresourceviewresolver">

<Property name = "prefix">

<Value>/WEB-INF/pages/</value>

</Property>

<Property name = "suffix">

<Value>. jsp </value>

</Property>

</Bean>

The returned result is: prefix + view name + suffix =/WEB-INF/pages/welcompage. jsp

2) xmlviewresolver

Example:

<Bean

Class = "org. springframework. Web. servlet. MVC. Support. controllerclassnamehandlermapping"/>

<! -- Register the bean -->

<Bean class = "com. mkyong. Common. Controller. welcomecontroller"/>

<Bean class = "org. springframework. Web. servlet. View. xmlviewresolver">

<Property name = "location">

<Value>/WEB-INF/spring-views.xml </value>

</Property>

</Bean>

Spring-views.xml

<Beans xmlns = "http://www.springframework.org/schema/beans"

Xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance"

Xsi: schemalocation = "http://www.springframework.org/schema/beans

Http://www.springframework.org/schema/beans/spring-beans-2.5.xsd>

<Bean id = "welcomepage"

Class = "org. springframework. Web. servlet. View. jstlview">

<Property name = "url" value = "/WEB-INF/pages/welcomepage. jsp"/>

</Bean>

</Beans>

In fact, it is easy to understand the configuration of view separately.

3 resourcebundleviewresolver

Example:

<Bean class = "com. mkyong. Common. Controller. welcomecontroller"/>

<Bean class = "org. springframework. Web. servlet. View. resourcebundleviewresolver">

<Property name = "basename" value = "Spring-views"/>

</Bean>

At this time, in fact, go to the class directory under the spring-views.properties to find the relevant view, View

The configuration is as follows:

Welcomepage. (class) = org. springframework. Web. servlet. View. jstlview

Welcomepage. url =/WEB-INF/pages/welcomepage. jsp

4 View Resolvers priority

<Beans...>

<Bean class = "org. springframework. Web. servlet. View. xmlviewresolver">

<Property name = "location">

<Value>/WEB-INF/spring-views.xml </value>

</Property>

<Property name = "order" value = "0"/>

</Bean>

<Bean class = "org. springframework. Web. servlet. View. resourcebundleviewresolver">

<Property name = "basename" value = "Spring-views"/>

<Property name = "order" value = "1"/>

</Bean>

<Bean id = "viewresolver"

Class = "org. springframework. Web. servlet. View. internalresourceviewresolver">

<Property name = "prefix">

<Value>/WEB-INF/pages/</value>

</Property>

<Property name = "suffix">

<Value>. jsp </value>

</Property>

<Property name = "order" value = "2"/>

</Bean>

</Beans>

Note that the lower the number, the higher the priority, the above order is:

Xmlviewresolver --> resourcebundleviewresolver --> internalresourceviewresolver
