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.
