本篇文章给大家带来的内容是关于springboot2.0整合同时支持jsp+html跳转的方法介绍(附代码),有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。
说明一下 。整合会遇到的问题,
1、pom.xml文件同时放入thymeleaf 架包和jsp支持后, springboot的return模版会默认跳转到html ,
那怕是你并没有配置thymeleaf的属性
解决方案, 使用getRequestDispatcher方法来跳转到jsp页面, 就同时支持html和jsp了
request.getRequestDispatcher("/WEB-INF/views/testJsp.jsp").forward(request, response);
2、另外 使用getRequestDispatcher跳转到html页面的时候,thymeleaf 模版接收参数可能会出现问题。
解决方案1:html放弃使用thymeleaf 模版,然后在页面主动请求接口数据(AJAX POST等)
解决方案2:html继续使用thymeleaf 模版,用return模版 返回来跳转页面
代码 UserController.java
package com.example.demo.controller; import com.example.demo.service.UserService; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import javax.annotation.Resource; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; import java.util.HashMap; import java.util.List; import java.util.Map; /** * @author chenlin */ @Controller @RequestMapping("/usersDemo") public class UserController { private static Logger log = LoggerFactory.getLogger(UserController.class); @Resource UserService userService; @ResponseBody @RequestMapping(value = "/test", produces = "application/json;charset=UTF-8", method = {RequestMethod.POST, RequestMethod.GET}) public List<Map<String, Object>> test(){ log.info("进入了test方法!"); List<Map<String,Object>> list=userService.userQueryAll(); return list; } @RequestMapping(value = "/testHtml", produces = "application/json;charset=UTF-8", method = {RequestMethod.POST, RequestMethod.GET}) public String testHtml(HttpServletRequest request, HttpServletResponse response){ List<Map<String,Object>> list=userService.userQueryAll(); request.setAttribute("list",list); log.info("进入了testHtml方法!"); return "views/testHtml"; } @RequestMapping(value = "/testJsp", produces = "application/json;charset=UTF-8", method = {RequestMethod.POST, RequestMethod.GET}) public void testJsp( HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Map<String,Object>> list=userService.userQueryAll(); request.setAttribute("list",list); log.info("进入了testJsp方法!"); request.getRequestDispatcher("/WEB-INF/views/testJsp.jsp").forward(request, response); } }

以上就完了。
另外附加一个return 模版的java代码配置, 可以配置return模版的优先级,后面的文件格式,当然只能用getRequestDispatcher来跳转了
在启动类中添加,另外,配置文件参数和代码可重复 但是代码优先于配置文件。
/** * 添加对jsp支持 * */ @Bean public ViewResolver getJspViewResolver() { InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver(); internalResourceViewResolver.setPrefix("/WEB-INF/");//前缀 internalResourceViewResolver.setSuffix(".jsp");//后缀 internalResourceViewResolver.setOrder(0);//优先级 return internalResourceViewResolver; } /** * 添加对Freemarker支持 * */ @Bean public FreeMarkerViewResolver getFreeMarkerViewResolver() { FreeMarkerViewResolver freeMarkerViewResolver = new FreeMarkerViewResolver(); freeMarkerViewResolver.setCache(false); freeMarkerViewResolver.setPrefix("/WEB-INF/");//前缀 freeMarkerViewResolver.setSuffix(".html");//后缀 freeMarkerViewResolver.setRequestContextAttribute("request"); freeMarkerViewResolver.setOrder(1);//优先级 freeMarkerViewResolver.setContentType("text/html;charset=UTF-8"); return freeMarkerViewResolver; }
