java - Problems with rendering JSP in spring boot -
i have spring boot application want use jsp
here dependencies in pom.xml
<parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>1.4.0.m2</version> <relativepath/> <!-- lookup parent repository --> </parent> <properties> <project.build.sourceencoding>utf-8</project.build.sourceencoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-data-jpa</artifactid> </dependency> <dependency> <groupid>org.jsoup</groupid> <artifactid>jsoup</artifactid> <version>1.8.3</version> </dependency> <dependency> <groupid>javax.mail</groupid> <artifactid>mail</artifactid> <version>1.5.0-b01</version> </dependency> <dependency> <groupid>org.apache.tomcat.embed</groupid> <artifactid>tomcat-embed-jasper</artifactid> <scope>provided</scope> </dependency> <dependency> <groupid>javax.servlet</groupid> <artifactid>jstl</artifactid> <scope>provided</scope> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-web</artifactid> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-mail</artifactid> </dependency> <dependency> <groupid>mysql</groupid> <artifactid>mysql-connector-java</artifactid> <scope>runtime</scope> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-test</artifactid> <scope>test</scope> </dependency> </dependencies> when try load jsp page has
<!doctype html> then page partially shown correctly, not - example
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contenttype="text/html;charset=utf-8" language="java" pageencoding="utf-8"%> <%@taglib uri="http://www.springframework.org/tags" prefix="spring"%> is displayed on screen.
when delete <!doctype html> - see plain html, no view.
i tried add , delete dependencies , if add or delete
<dependency> <groupid>org.apache.tomcat.embed</groupid> <artifactid>tomcat-embed-jasper</artifactid> <scope>provided</scope> </dependency> <dependency> <groupid>javax.servlet</groupid> <artifactid>jstl</artifactid> <scope>provided</scope> </dependency> <dependency> <groupid>org.apache.tomcat.embed</groupid> <artifactid>tomcat-embed-el</artifactid> <scope>provided</scope> </dependency> nothing changes - still receive either plain html or partially visible jsp.
i have same problem both when run in intellijidea , when run compiled jar
i stuck here , feels won't ever make :( looked @ huge amount of tutorials , many questions on stackoverflow found no help.
any advice appreciated!
update when use pom.xml https://github.com/spring-projects/spring-boot/blob/master/spring-boot-samples/spring-boot-sample-web-jsp/pom.xml error

try add properties application.properties (src/main/resources/):
spring.mvc.view.prefix: /web-inf/jsp/ spring.mvc.view.suffix: .jsp put jsps /web-inf/jsp/
in controller return example "index" should have index.jsp in folder /web-inf/jsp/
make sure configuration , @enablewebmvc present.
