springboot返回modelandview頁(yè)面的實(shí)例

這篇文章主要介紹了springboot返回modelandview頁(yè)面的實(shí)例，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟隨小編過(guò)來(lái)看看吧

1、添加依賴

這個(gè)應(yīng)該是web項(xiàng)目相關(guān)的jar

 <dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
 <!-- jstl JSP標(biāo)準(zhǔn)標(biāo)簽庫(kù) -->
 <dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>jstl</artifactId>
   <version>1.2</version>
 </dependency>
 <!-- 返回jsp頁(yè)面還需要這個(gè)依賴 -->
 <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>

我這里是parent是1.5.10，所以jsp的配置應(yīng)該如下

#jsp path
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
老版本的應(yīng)該是這個(gè)
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp

3、控制器

因?yàn)槭欠祷仨?yè)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數(shù)據(jù)
 //@Controller，返回login.jsp頁(yè)面
 @RequestMapping(value = "/login", method = RequestMethod.GET)
 public String login(HttpServletRequest request,HttpServletResponse response){
 
 return "login";
 }
 
 //無(wú)論是@RestController還是@Controller都不影響返回頁(yè)面
 @RequestMapping(value = "/loginPage", method = RequestMethod.GET)
 public ModelAndView loginPage(HttpServletRequest request,HttpServletResponse response){
 ModelAndView mav = new ModelAndView();
 mav.setViewName("login");
 
 return mav;
 }
}

補(bǔ)充知識(shí)：springBoot前后分離項(xiàng)目，通過(guò)ModelAndView返回給app或前臺(tái)靜態(tài)頁(yè)面

1.先做靜態(tài)頁(yè)模板aaa.html,放到springboot項(xiàng)目的根目錄下，如下如中，新建一個(gè)templates的文件夾，將靜態(tài)頁(yè)放到這里面就可以了

靜態(tài)頁(yè)代碼為

<!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>標(biāo)題</title>
  <style type="text/css">
    body {
      margin-left: 0px;
      margin-top: 0px;
      margin-right: 0px;
      margin-bottom: 0px;
      background: #f3f3f3;
      font-family: "Microsoft YaHei ", "微軟雅黑", "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層，業(yè)務(wù)邏輯根據(jù)自己的需求來(lái)

@RequestMapping("/html")
@Controller
public class AppCommonHtmlController {
  
  @RequestMapping(value = "/ceshi", method = RequestMethod.GET)
  public ModelAndView getCeishi(“根據(jù)自己業(yè)務(wù)傳入需要的參數(shù)”) {
    ModelAndView modelAndView=new ModelAndView();
    //根據(jù)自己的業(yè)務(wù)，和靜態(tài)頁(yè)中的參數(shù)對(duì)應(yīng)上就行，也可以放入實(shí)體類，和靜態(tài)頁(yè)面對(duì)應(yīng)就行了
    modelAndView.addObject("title",“標(biāo)題”);
    modelAndView.addObject("addDate",“添加時(shí)間”);
    modelAndView.addObject("content",“內(nèi)容”);
    //存入靜態(tài)頁(yè)的名稱，就可以把處理好的靜態(tài)頁(yè)返回給app或前臺(tái)
    modelAndView.setViewName("aaa");
    return modelAndView;
  }
}

然后瀏覽器輸入：http://localhost:8888/項(xiàng)目名/html/ceshi

該方法多適用于app端，需要根據(jù)不同的情況得到不一樣內(nèi)容的靜態(tài)頁(yè)展示到手機(jī)上，就可以通過(guò)這種方法，做一個(gè)靜態(tài)頁(yè)的模板，通過(guò)el表達(dá)式給模板不同的內(nèi)容，然后app端可以通過(guò)訪問(wèn)的ip直接獲取到靜態(tài)頁(yè)

下面的方法也可以，效果同上面一樣

靜態(tài)頁(yè)代碼

<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-spring4-4.dtd">

      margin-left: 0px;
      margin-top: 0px;
      margin-right: 0px;
      margin-bottom: 0px;
      background: #f3f3f3;
      font-family: "Microsoft YaHei ", "微軟雅黑", "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代碼

  @RequestMapping(value = "/ceshi", method = RequestMethod.GET)
  public String getCeishi(“業(yè)務(wù)邏輯需要的入?yún)ⅰ? Model model) {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    JSONObject jsonObject = JSONObject.fromObject(“需要傳到靜態(tài)頁(yè)的動(dòng)態(tài)數(shù)據(jù)”);
    jsonObject.remove("publishDate");//時(shí)間，具體作用不清楚，個(gè)人猜測(cè)是原本數(shù)據(jù)格式不支持，需要轉(zhuǎn)換一下，所以要先刪除后重新賦值
    jsonObject.put("publishDate", sdf.format(notice.getPublishDate()));//時(shí)間重新賦值
    model.addAttribute("bbb", jsonObject);//將轉(zhuǎn)換好的數(shù)據(jù)存入model中
    return "aaa"; //對(duì)應(yīng)好靜態(tài)頁(yè)的名稱return出去就可以了
  }

以上這篇springboot返回modelandview頁(yè)面的實(shí)例就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
