Springboot 2.0.8 Introduction to the method of jumping to jsp page (with code)

This article brings you an introduction to the method of jumping to jsp pages in springboot 2.0.8 (with code). It has certain reference value. Friends in need can refer to it. I hope it will be useful to you. Helps.

This is a tutorial to jump to the jsp page alone. Later, I will introduce the coexistence of html and jsp. I temporarily annotated the thymeleaf template and configuration

1 Create directory results and jsp files

2 Configure return return template and code

@RequestMapping(value = "/testJsp", produces = "application/json;charset=UTF-8", method = {RequestMethod.POST, RequestMethod.GET})
    public String testJsp(Model m, HttpServletRequest request, HttpServletResponse response){
        List<Map<String,Object>> list=userService.userQueryAll();
        request.setAttribute("list",list);
        log.info("进入了testJsp方法！");
        return "views/testJsp";
    }

3.application.yml file configuration thymeleaf template parameters

spring:
  dataSource:
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://localhost:3306/db-test?useUnicode=true&characterEncoding=utf8&tinyInt1isBit=false&usessl=false
    username: root
    password: 123456
    driverClassName: com.mysql.jdbc.Driver
  mvc:
    view: #新版本 1.3后可以使用
      suffix: .jsp
      prefix: /WEB-INF/
  view: #老版本 1.4后被抛弃
    suffix: .jsp
    prefix: /WEB-INF/

4.pom.xml file Add tomcat and jsp support. If there is a thymeleaf rack package, comment it out temporarily. Here only write jsp jump ( When there is a thymeleaf rack package, the return template will give priority to jump to the html page)

<!--tomcat支持-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>
        <!--servlet依赖.-->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>4.0.1</version>
            <scope>provided</scope>
        </dependency>
        <!--jsp标签库-->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>

5. The EL expression is used directly in the jsp page

<%@ page contentType="text/html;charset=UTF-8" isELIgnored="false" pageEncoding="UTF-8" %>
<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c" %>
<%
    String path = request.getContextPath();
    String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
<!DOCTYPE html >
<html lang="zh-CN">
<head>
    <title>Title</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <script src="<%=basePath%>static/js/jquery-3.3.1.js" charset="utf-8"></script>
</head>
<body>
<table border="1">
    <thead>
    <tr>
        <th>序号</th>
        <th>名字</th>
        <th>号码</th>
        <th>创建时间</th>
    </tr>
    </thead>
    <tbody>
    <c:forEach items="${list}" var="listv" varStatus="status">
        <tr>
            <td>${listv.id}</td>
            <td>${listv.name}</td>
            <td>${listv.phone}</td>
            <td>${listv.create_time}</td>
        </tr>
    </c:forEach>
    </tbody>
</table>

</body>
<script type="text/javascript" charset="utf-8">

</script>
</html>

6. This is usually configured by default in the Project Structure. If not, you need to add it

Just start it like this. The rendering is as follows
