================================
Spring MVC组件配置之ViewResolver
================================

ViewResolver

- 视图解析器
- 解析ModeAndView，分离模型和视图
- 可根据需要进行配置，不配置则使用默认视图解析器

1 UrlBasedViewResolver

<!-- JSTL -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver>
    <property name="viewClass" value="JstlView" />
    <property name="prefix" value="/" />
    <property name="suffix" value=".jsp />
</bean>

...
public class BookController {
    ...
    public String addBook(...) {
        ...
        return "addBookSuccess";
    }
    ...
}

2 InternalResourceViewResolver

<!-- JSTL -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

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

...
public class BookController {
    ...
    public String addBook(...) {
        ...
        return "addBookSuccess";
    }
    ...
}
