springboot返回modelandview springboot返回modelandview页面的实例
不屑哥 人气:0想了解springboot返回modelandview页面的实例的相关内容吗,不屑哥在本文为您仔细讲解springboot返回modelandview的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:springboot,modelandview,下面大家一起来学习吧。
1、添加依赖
这个应该是web项目相关的jar
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>
<!-- jstl JSP标准标签库 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 返回jsp页面还需要这个依赖 --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency>
2、application.properties
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.10.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>
我这里是parent是1.5.10,所以jsp的配置应该如下
#jsp path spring.mvc.view.prefix=/WEB-INF/jsp/ spring.mvc.view.suffix=.jsp 老版本的应该是这个 spring.view.prefix=/WEB-INF/jsp/ spring.view.suffix=.jsp
3、控制器
因为是返回页面,所以不能用@RestController返回json格式
package com.example.demo.controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.context.annotation.ComponentScan; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.ModelAndView; @Controller /*@ComponentScan*/ @RequestMapping("/test") public class TestController { private final Logger log = LoggerFactory.getLogger(this.getClass()); @RequestMapping(value = "queryMaterialType", method = RequestMethod.POST) public Object test(){ log.info("--------------->>打印日志"); return "hellow world"; } //@RestController,返回json数据 //@Controller,返回login.jsp页面 @RequestMapping(value = "/login", method = RequestMethod.GET) public String login(HttpServletRequest request,HttpServletResponse response){ return "login"; } //无论是@RestController还是@Controller都不影响返回页面 @RequestMapping(value = "/loginPage", method = RequestMethod.GET) public ModelAndView loginPage(HttpServletRequest request,HttpServletResponse response){ ModelAndView mav = new ModelAndView(); mav.setViewName("login"); return mav; } }
补充知识:springBoot前后分离项目,通过ModelAndView返回给app或前台静态页面
1.先做静态页模板aaa.html,放到springboot项目的根目录下,如下如中,新建一个templates的文件夹,将静态页放到这里面就可以了
静态页代码为
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-spring4-4.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"> <meta name="viewport" content="width=device-width, initial-scale=0.0, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0"> <meta content="yes" name="apple-mobile-web-app-capable"> <meta content="black" name="apple-mobile-web-app-status-bar-style"> <meta content="telephone=no" name="format-detection"> <title>标题</title> <style type="text/css"> body { margin-left: 0px; margin-top: 0px; margin-right: 0px; margin-bottom: 0px; background: #f3f3f3; font-family: "Microsoft YaHei ", "微软雅黑", "arial"; } h1 { height: 1px; width: 100%; margin: 10px 0; background: #f1f1f1; } img { width: 100%; height: auto; } .bodys { width: 100%; height: auto; overflow: Hidden; padding-top: 10px; padding-bottom: 50px; background: #fff; } .head { width: 96%; min-height: 30px; padding: 18px 2% 2px 2%; line-height: 25px; text-align: left; font-size: 20px; font-weight: bold; color: #111; } .time { width: 96%; height: 20px; line-height: 20px; font-size: 11px; text-align: left; padding: 0 2%; color: #999; } .info { width: 96%; height: auto; padding: 10px 2%; line-height: 25px; text-align: left; font-size: 15px; } </style> </head> <body> <div class="bodys"> <div class="head" th:text="${itle}">未知</div> <div class="time" th:text="${addDate}">未知</div> <h1></h1> <div class="info" th:utext="${content}">未知</div> </div> </body> </html>
2.然后主要是 controller层,业务逻辑根据自己的需求来
@RequestMapping("/html") @Controller public class AppCommonHtmlController { @RequestMapping(value = "/ceshi", method = RequestMethod.GET) public ModelAndView getCeishi(“根据自己业务传入需要的参数”) { ModelAndView modelAndView=new ModelAndView(); //根据自己的业务,和静态页中的参数对应上就行,也可以放入实体类,和静态页面对应就行了 modelAndView.addObject("title",“标题”); modelAndView.addObject("addDate",“添加时间”); modelAndView.addObject("content",“内容”); //存入静态页的名称,就可以把处理好的静态页返回给app或前台 modelAndView.setViewName("aaa"); return modelAndView; } }
然后浏览器输入:http://localhost:8888/项目名/html/ceshi
该方法多适用于app端,需要根据不同的情况得到不一样内容的静态页展示到手机上,就可以通过这种方法,做一个静态页的模板,通过el表达式给模板不同的内容,然后app端可以通过访问的ip直接获取到静态页
下面的方法也可以,效果同上面一样
静态页代码
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-spring4-4.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"> <meta name="viewport" content="width=device-width, initial-scale=0.0, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0"> <meta content="yes" name="apple-mobile-web-app-capable"> <meta content="black" name="apple-mobile-web-app-status-bar-style"> <meta content="telephone=no" name="format-detection"> <title>静态页</title> <style type="text/css"> body { margin-left: 0px; margin-top: 0px; margin-right: 0px; margin-bottom: 0px; background: #f3f3f3; font-family: "Microsoft YaHei ", "微软雅黑", "arial"; } h1 { height: 1px; width: 100%; margin: 10px 0; background: #f1f1f1; } img { width: 100%; height: auto; } .bodys { width: 100%; height: auto; overflow: Hidden; padding-top: 10px; padding-bottom: 50px; background: #fff; } .head { width: 96%; min-height: 30px; padding: 18px 2% 2px 2%; line-height: 25px; text-align: left; font-size: 20px; font-weight: bold; color: #111; } .time { width: 96%; height: 20px; line-height: 20px; font-size: 11px; text-align: left; padding: 0 2%; color: #999; } .info { width: 96%; height: auto; padding: 10px 2%; line-height: 25px; text-align: left; font-size: 15px; } </style> </head> <body> <div class="bodys"> <div class="head" th:text="${bbb.noticeTitle}">未知</div> <div class="time" th:text="${bbb.publishDate}">未知</div> <h1></h1> <div class="info" th:utext="${bbb.noticeContent}">未知</div> </div> </body> </html>
controller代码
@RequestMapping(value = "/ceshi", method = RequestMethod.GET) public String getCeishi(“业务逻辑需要的入参”, Model model) { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); JSONObject jsonObject = JSONObject.fromObject(“需要传到静态页的动态数据”); jsonObject.remove("publishDate");//时间,具体作用不清楚,个人猜测是原本数据格式不支持,需要转换一下,所以要先删除后重新赋值 jsonObject.put("publishDate", sdf.format(notice.getPublishDate()));//时间重新赋值 model.addAttribute("bbb", jsonObject);//将转换好的数据存入model中 return "aaa"; //对应好静态页的名称return出去就可以了 }
