springMVC同时支持跳转jsp和html

想要实现如以下效果

@Controller  //RestController代表controller,但是是和ResponseBody结合
@RequestMapping("adminC")  //不能@RequestMapping("/adminC")

public class AdminController {


   
    private AdminService adminService;


    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String index(HttpServletRequest request, Model model) {
        return "base/admin/index";
    }

    @RequestMapping(value = "/index2", method = RequestMethod.GET)
    public String index2(HttpServletRequest request, Model model) {
        return "base/admin/index2";
    }


}

其中，index是html，index2是jsp，如果同名，先跳转jsp

======================================

1.配置HtmlResourceView,创建类

package org.pb.base.servlet;

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

import java.io.File;
import java.util.Locale;

public class HtmlResourceView extends InternalResourceView {

    @Override
    public boolean checkResource(Locale locale){
        File file=new File(this.getServletContext().getRealPath("/")+getUrl());
        return file.exists(); //判断页面是否存在
    }
}

2.配置spring-mvc.xml

 <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀-->
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!--<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />-->
        <property name="viewClass"
                  value="org.pb.base.servlet.HtmlResourceView" />
		<!-- 通过setter方法注入前缀 /WEB-INF/views/showMsg.jsp-->
		<property name="prefix" value="/" />
		<!-- 通过setter方法注入后缀 -->
		<property name="suffix" value=".jsp" />

		<property name="order" value="1" />
	</bean>

    <bean id="htmlviewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.pb.base.servlet.HtmlResourceView"/>
        <property name="order" value="2" />
        <property name="prefix" value="/"/>
        <property name="suffix" value=".html" />
        <property name="contentType" value="text/html;charset=UTF-8"></property>
    </bean>

其中order属性越小，优先级越高，而prefix不是一成不变的，你可以看下你的target目录下，页面的具体路径来配置
