springboot返回modelandview页面的实例

时间:2021-05-19

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 pathspring.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@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://patible" 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 }
