SPRING IN ACTION 第4版笔记-第六章Rendering web views-001- Spring支持的View Resolver、InternalResourceViewResolver、JstlView

一、Spring支持的View Resolver

二、InternalResourceViewResolver

Spring supports JSP views in two ways:
 InternalResourceViewResolver 
 Spring provides two JSP tag libraries, one for form-to-model binding and one providing general utility features.

1.在java中定义

 package spittr.web;

 import org.springframework.context.MessageSource;

 import org.springframework.context.annotation.Bean;

 import org.springframework.context.annotation.ComponentScan;

 import org.springframework.context.annotation.Configuration;

 import org.springframework.context.support.ReloadableResourceBundleMessageSource;

 import org.springframework.web.servlet.ViewResolver;

 import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;

 import org.springframework.web.servlet.config.annotation.EnableWebMvc;

 import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;

 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

 import org.springframework.web.servlet.view.InternalResourceViewResolver;

 @Configuration

 @EnableWebMvc

 @ComponentScan("spittr.web")

 public class WebConfig extends WebMvcConfigurerAdapter {

   @Bean

   public ViewResolver viewResolver() {

     InternalResourceViewResolver resolver = new InternalResourceViewResolver();

     resolver.setPrefix("/WEB-INF/views/");

     resolver.setSuffix(".jsp");

     return resolver;

   }

2.在xml中定义

 <?xml version="1.0" encoding="UTF-8"?>

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

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

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

   xmlns:context="http://www.springframework.org/schema/context"

   xsi:schemaLocation="http://www.springframework.org/schema/mvc

     http://www.springframework.org/schema/mvc/spring-mvc.xsd

     http://www.springframework.org/schema/beans

     http://www.springframework.org/schema/beans/spring-beans.xsd

     http://www.springframework.org/schema/context

     http://www.springframework.org/schema/context/spring-context.xsd">

   <annotation-driven />

   <context:component-scan base-package="spitter" />

   <beans:bean

     class="org.springframework.web.servlet.view.InternalResourceViewResolver">

     <beans:property name="prefix" value="/WEB-INF/views/" />

     <beans:property name="suffix" value=".jsp" />

   </beans:bean>

   <resources mapping="/resources/**" location="/resources/" />

   <!--

   <view-controller path="/" view-name="home" />

   -->

 </beans:beans>

By resolving JstlView , the JSTL tags will be given the Locale and any message source configured in Spring.

3.

 @Bean

 public ViewResolver viewResolver() {

     InternalResourceViewResolver resolver =

         new InternalResourceViewResolver();

     resolver.setPrefix("/WEB-INF/views/");

     resolver.setSuffix(".jsp");

     resolver.setViewClass(

         org.springframework.web.servlet.view.JstlView.class);

     return resolver;

 }

4.

 <bean

   id="viewResolver"

   class="org.springframework.web.servlet.view.

   InternalResourceViewResolver"

   p:prefix="/WEB-INF/views/"

   p:suffix=".jsp"

   p:viewClass="org.springframework.web.servlet.view.JstlView" />

Whether you use Java configuration or XML , this will ensure that JSTL ’s formatting and message tags will get the Locale and message sources configured in Spring.
