2 解析多视图请求的类

[java]
package com.spring.action;

import java.util.Locale;
import java.util.Map;
import org.springframework.web.servlet.View;
import org.springframework.web.servlet.ViewResolver;

public class MultiViewResover implements ViewResolver {

private Map resolvers;

@Override
public View resolveViewName(String viewName, Locale locale)
throws Exception {
int n = viewName.lastIndexOf("_"); // 获取
// viewName(modelAndView中的名字)看其有没有下划线
if (n == (-1))
return null; // 没有则直接返回空
// 有的话截取下划线后面的字符串这里一般是jsp,ftl,vm与配置文件中的的key匹配
String suffix = viewName.substring(n + 1);
// 根据下划线后面的字符串去获取托管的视图解析类对象
ViewResolver resolver = resolvers.get(suffix);

// 取下划线前面的部分那时真正的资源名.比如我们要使用hello.jsp 那viewName就应该是hello_jsp
