SpringMVC view resolver configuration

 

Usually we view as to the parser configuration:

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

At this time  InternalResourceViewResolver parsing component, the default will be parsed  org.springframework.web.servlet.view.InternalResourceView view.

 

 

If added in appropriate package jstl classpath, as follows:

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.1.2</version>
        </dependency>

 

At this time  InternalResourceViewResolver parsing component, the default will be parsed  org.springframework.web.servlet.view.JstlView view.

Principles are as follows (if jstlPresent to true):

private static final boolean jstlPresent = ClassUtils.isPresent(
			"javax.servlet.jsp.jstl.core.Config", InternalResourceViewResolver.class.getClassLoader());

 

	/**
	 * Sets the default {@link #setViewClass view class} to {@link #requiredViewClass}:
	 * by default {@link InternalResourceView}, or {@link JstlView} if the JSTL API
	 * is present.
	 */
	public InternalResourceViewResolver() {
		Class<?> viewClass = requiredViewClass();
		if (InternalResourceView.class == viewClass && jstlPresent) {
			viewClass = JstlView.class;
		}
		setViewClass(viewClass);
	}

 

We can specify the view class to be used (arranged viewClass InternalResourceViewResolver parsing component attribute to specify the parsed view class):

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

Specifies the view class may not be directly added jstl package, using default frame jstlview
