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

 1 package spittr.web;
 2
 3 import org.springframework.context.MessageSource;
 4 import org.springframework.context.annotation.Bean;
 5 import org.springframework.context.annotation.ComponentScan;
 6 import org.springframework.context.annotation.Configuration;
 7 import org.springframework.context.support.ReloadableResourceBundleMessageSource;
 8 import org.springframework.web.servlet.ViewResolver;
 9 import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
10 import org.springframework.web.servlet.config.annotation.EnableWebMvc;
11 import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
12 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
13 import org.springframework.web.servlet.view.InternalResourceViewResolver;
14
15 @Configuration
16 @EnableWebMvc
17 @ComponentScan("spittr.web")
18 public class WebConfig extends WebMvcConfigurerAdapter {
19
20   @Bean
21   public ViewResolver viewResolver() {
22     InternalResourceViewResolver resolver = new InternalResourceViewResolver();
23     resolver.setPrefix("/WEB-INF/views/");
24     resolver.setSuffix(".jsp");
25     return resolver;
26   }

2.在xml中定义

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans:beans xmlns="http://www.springframework.org/schema/mvc"
 3   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4   xmlns:beans="http://www.springframework.org/schema/beans"
 5   xmlns:context="http://www.springframework.org/schema/context"
 6   xsi:schemaLocation="http://www.springframework.org/schema/mvc
 7     http://www.springframework.org/schema/mvc/spring-mvc.xsd
 8     http://www.springframework.org/schema/beans
 9     http://www.springframework.org/schema/beans/spring-beans.xsd
10     http://www.springframework.org/schema/context
11     http://www.springframework.org/schema/context/spring-context.xsd">
12
13   <annotation-driven />
14
15   <context:component-scan base-package="spitter" />
16
17   <beans:bean
18     class="org.springframework.web.servlet.view.InternalResourceViewResolver">
19     <beans:property name="prefix" value="/WEB-INF/views/" />
20     <beans:property name="suffix" value=".jsp" />
21   </beans:bean>
22
23   <resources mapping="/resources/**" location="/resources/" />
24
25   <!--
26   <view-controller path="/" view-name="home" />
27   -->
28
29 </beans:beans>

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

3.

 1 @Bean
 2 public ViewResolver viewResolver() {
 3     InternalResourceViewResolver resolver =
 4         new InternalResourceViewResolver();
 5     resolver.setPrefix("/WEB-INF/views/");
 6     resolver.setSuffix(".jsp");
 7     resolver.setViewClass(
 8         org.springframework.web.servlet.view.JstlView.class);
 9     return resolver;
10 }

4.

1 <bean
2   id="viewResolver"
3   class="org.springframework.web.servlet.view.
4   InternalResourceViewResolver"
5   p:prefix="/WEB-INF/views/"
6   p:suffix=".jsp"
7   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.
