SpringMVC 配置多视图解析器(velocity,jsp)

1.自定义视图解析器

package com.zhaochao.controller;import java.util.HashMap;import java.util.Locale;import java.util.Map;import java.util.Set;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.web.servlet.View;import org.springframework.web.servlet.ViewResolver;/** * 自定义视图解析(通过配置实现多视图整合,如jsp,velocity,freemarker,pdf,excel...) * @author zhaochao * */public class JeeDevViewResolver implements ViewResolver  {    private static Log logger = LogFactory.getLog(JeeDevViewResolver.class);    public View resolveViewName(String viewName, Locale locale) throws Exception {       for(Map.Entry<Set<String>, ViewResolver> map : viewResolverMap.entrySet()){           Set<String> suffixs = map.getKey();           for(String suffix : suffixs){           System.out.println(suffix+" == "+viewName);               if (viewName.endsWith(suffix)){                   ViewResolver viewResolver = map.getValue();                   if(null != viewResolver){                       if (logger.isDebugEnabled()) {                            logger.debug("found viewResolver '" + viewResolver + "' for viewName '" + viewName+ "'");                        }                       return viewResolver.resolveViewName(viewName, locale);                   }               }           }       }       if(defaultViewResolver != null){           return defaultViewResolver.resolveViewName(viewName+".jsp", locale);       }       // to allow for ViewResolver chaining       return null;    }    private Map<Set<String>,ViewResolver> viewResolverMap = new HashMap<Set<String>,ViewResolver>();    private ViewResolver defaultViewResolver = null;    public Map<Set<String>, ViewResolver> getViewResolverMap() {        return viewResolverMap;    }    public void setViewResolverMap(Map<Set<String>, ViewResolver> viewResolverMap) {        this.viewResolverMap = viewResolverMap;    }    public ViewResolver getDefaultViewResolver() {        return defaultViewResolver;    }    public void setDefaultViewResolver(ViewResolver defaultViewResolver) {        this.defaultViewResolver = defaultViewResolver;    }}

3.Controller控制器

package com.zhaochao.controller;import java.util.List;import javax.servlet.http.HttpServletRequest;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import com.zhaochao.bean.user.UserBean;import com.zhaochao.service.user.UserService;@Controller@RequestMapping("/userAction")public class UserController {private UserService userService;public UserService getUserService() {return userService;}@Autowiredpublic void setUserService(UserService userService) {this.userService = userService;}@RequestMapping(value = "/def")public String def(HttpServletRequest request, ModelMap map) {map.put("name", "hello world");request.setAttribute("name", "hello wrod!");List<UserBean> users=userService.getUserEntities();map.put("name", "hello world");map.put("users", users);return "def";}@RequestMapping(value = "/jsp")public String test1(HttpServletRequest request, ModelMap map) {map.put("name", "hello world");request.setAttribute("name", "hello wrod!");List<UserBean> users=userService.getUserEntities();map.put("name", "hello world");map.put("users", users);return "index.jsp";}@RequestMapping(value = "/vm")public String test3(HttpServletRequest request, ModelMap map) {List<UserBean> users=userService.getUserEntities();map.put("name", "hello world");map.put("users", users);return "index.vm";}}
