springmvc多個檢視解析器管理跳轉資源

專案結構

第一步：將所有資源交由springmvc管理

 <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <
 
param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
</servlet>
<servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern
 
>
</servlet-mapping>

在springmvc配置檔案中配置多個檢視解析器

根據屬性viewNames的value進行區分，*jsp*：處理器方法返回的資源包括jsp的則進來

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 

       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">
         <!--基於上下文進行對元件的掃描-->
    <context:component-scan base-package="com.yyjc.springmvc.handler"/>
	
    <mvc:annotation-driven/>
    <!--使用預設的Servlet來響應靜態檔案-->
    <mvc:default-servlet-handler/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".jsp"/>
        <property name="viewNames" value="*jsp*"/>
        <property name="order" value="2"/>
    </bean>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"/>
        <property name="suffix" value=".html"/>
        <property name="viewNames" value="i*"/>
        <property name="order" value="1"/><!--order:設定優先順序，order值越低，則優先順序越高-->
    </bean>
</beans>

第二步：處理器方法返回跳轉資源

注：方法返回結果可以是ModelAndView或者String

@RequestMapping("/userlogin.action")
    public String userLogin() {
        System.out.println("進來了");
        return "jsp/success";
	}
/*
@RequestMapping("/userlogin.action")
    public ModelAndView userLogin()  {
        ModelAndView modelAndView = new ModelAndView();
        System.out.println("進來了");
        modelAndView.setViewName("index");
        return modelAndView;
 	}
*/
