Outline
(1) Create MAVEN Web project;
(2) add dependency in Pom.xml file
(3) Configuring Application.properties support JSP
(4) Writing test controller
(5) Writing JSP pages
(6) Writing the startup class App.java
Create a MAVEN Web project
Use Eclipse to create a new Maven Web project named: spring-boot-jsp
Adding dependencies in the Pom.xml file
<!--spring Boot parent node, after introducing this, there is no need to introduce a version in the following spring boot related; -
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.1.RELEASE</version>
</parent>
<!--Specify the JDK version, where we use JDK 1.8, which by default is 1.6--
<java.version>1.8</java.version>
<!--Web Support: 1, Web MVC; 2, restful; 3, Jackjson support; 4. AOP ...--
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--servlet dependency. -
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
JSTL (JSP standard tag LIBRARY,JSP standards Tag library) is an ever-improving open source JSP tag library that is maintained by Apache's Jakarta team.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!--Tomcat Support .-->
<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>
Application.properties Configuration
Add Src/main/resources/application.properties:
# page Default prefix directory
spring.mvc.view.prefix=/web-inf/jsp/
# response page Default suffix
spring.mvc.view.suffix=.jsp
# Custom properties that can be read in the controller
Application.hello=hello Angel from Application
Writing a test controller
@Controller
public class Hellocontroller {
Private String Hello;
@RequestMapping ("/hellojsp")
Public String hellojsp (map<string,object> Map) {
System.out.println ("hellocontroller.hellojsp (). Hello=hello");
Map.put ("Hello", hello);
return "hellojsp";
}
}
Writing JSP pages
Create the webapp/web-inf/jsp directory below Src/main to store our JSP page: hellojsp.jsp:
<%@ page language= "java" contenttype= "text/html; Charset=utf-8 "
pageencoding= "UTF-8"%>
<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "HTTP://WWW.W3.ORG/TR/HTML4/LOOSE.DTD" >
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 ">
<title>insert title here</title>
<body>
hellojsp
${hello}
</body>
Writing startup classes
@SpringBootApplication
public class App {
public static void Main (string[] args) {
Springapplication.run (App.class, args);
}
}
The code is as follows:
Pom.xml
