Spring Boot JSP 404

In newer versions of Spring, following needs to be put in application.properties file:

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

Also, JSP files need to be put under src/main/resources/META-INF/resources/WEB-INF/jsp

This is working solution for me about White label error page : Cannot find view page(jsp)

At POM.xml, Make sure packaging is "war" and add tomcat/jasper dependencies

<packaging>war</packaging>
<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>

Add prefix/suffix at application.properties

spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp

** If you use Intellij, you must set Web Resource directories. At Project Structure (ctrl+alt+shift+ S) > Facets > Select Web(your application) > Add(+) Web Resource Directories ( mine is ......\src\main\webapp)

** If you have multiple modules(At intellij), Run> Edit configuration> Select springboot your application > Configuration tab> Working directory as $MODULE_WORKING_DIR$

Ensure that you have jasper and jstl in the list of dependencies:

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
    </dependency>
