These days in the focus on the Spring Boot+shiro framework, because before the view layer with more JSP, so you want to configure the JSP in spring boot, but spring boot officially does not recommend the use of JSP, because the JSP compared to some template engine, performance is relatively low, The official recommendation is to use Thymeleaf, but the spring boot integration JSP process has been completed and recorded here.
This blog post is based on the LZ last article Spring Boot+mybatis integration, development tools are still intellij idea. The focus of this article is IntelliJ idea settings, otherwise can not jump to the JSP page, reported 404.
Pom.xml added tomcat support and JSTL tag Library
<!--Tomcat support--><dependency> <groupId>org.apache.tomcat.embed</groupId> < Artifactid>tomcat-embed-jasper</artifactid> <!--<scope>provided</scope>--></ dependency><!--jstl Tag library--><dependency> <groupId>javax.servlet</groupId> < Artifactid>jstl</artifactid></dependency>
Second, configure the JSP path in APPLICATION.YML
Spring: MVC: View: # page Default prefix directory /web-inf/jsp/ # response page default suffix suffix:. JSP
Third, create the webapp/web-inf/jsp directory below Src/main to store our JSP pages.
index.jsp
<%@ Page Language="Java"pageencoding="UTF-8"%><!DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en"><HTML><Head><title>Spring Boot Sample</title></Head><Body>Time : ${time}<BR>Message: ${message}</Body></HTML>
page1.jsp

If you Baidu, most of the tutorial is so tell you, nothing new, but LZ tried several times did not succeed, some data said jar package does not support jsp,jsp need to run in ServletContext, The war package needs to run on the server server such as Tomcat (where the jar and war refer to the settings of <packaging>jar</packaging> in Pom.xml), which is not very troublesome in the development environment, In fact, just set the IntelliJ idea on it.
Intellij Idea Toolbar File->project Structure, select the modules in the pop-up page, select the Web in the middle column (without the "+" sign new), then set the deployment descriptors and the Web Resource directories (this variable should be the default), where deployment descriptors points to the project name/src/main/webapp/web-inf/ Web. XML, which currently does not have XML, will be created automatically, Resource directories by default, without modification.
Then you can test the browser input http://localhost:8080 Http://localhost:8080/page1 http://localhost:8080/page2 see the effect.
Since spring boot does not recommend the use of JSP, it can only be replaced by thymeleaf, of course, other such as Freemarker can also be selected.
