I have been using Spring Boot ReST APIs for quite some time; I thought of experimenting with web-MVC. However, I have got stuck on the first part itself.

I have uploaded the project on GitHub

What I have done so far:

  1. Defined POM.xml with spring-boot-starter-web + tomcat-embed-jasper mainly.
  2. Defined a @Controller with @GetMapping("/greeting"), which returns the name of a view - hello

  3. Defined following properties:

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

    spring.mvc.view.suffix=.jsp

  4. Created a very basic view hello.jsp at src/main/web/WEB-INF/views/hello.jsp

  5. Created a main Application to run as SpringBootApplication.

Error:

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404). No message available

EDIT:

I tried following changes as per the comments; however, it doesn't seem to help yet.

  1. Putting hello.jsp in src/main/resources/templates/WEB-INF/views
  2. Putting hello.jsp in src/main/resources/static/WEB-INF/views
  3. Putting hello.jsp in src/main/resources/WEB-INF/views
  4. Putting hello.jsp in src/main/webapp/WEB-INF/views

Please advise.

  • src/main/web, the 'web' folder should have been 'webapp' Commented Mar 26, 2018 at 18:13

Reset to default

The issue was with the provided scope of Maven Dependency tomcat-embed-jasper which is used to compile the JSPs.

With default scope for this maven dependency, it flies!

    <!-- Tomcat for JSP rendering -->
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
    </dependency>

Two cents from my analysis!

What is the use of this dependency when we already have spring-boot-starter-web?

The spring-boot-starter-web includes the spring-boot-starter-tomcat and the spring-boot-starter-tomcat includes the tomcat-embed-core.

But, tomcat-embed-core doesn't include tomcat-embed-jasper.

Now, according to maven docs, if the tomcat-embed-jasper is marked as provided, it means that it expects the JDK or a container to provide the dependency at runtime. This scope is only available on the compilation and test classpath, and is not transitive. Hence, effectively this dependency is not available when JSPs are being compiled.

By marking this dependency scope as compile, it is made available in all the classpaths and to all the dependent projects as well.

Summary: The spring-boot-starter-web has tomcat embedded dependency but it doesn't include the jasper embedded dependency. One needs to add this dependency with default compile scope.

Where to place the JSPs/View Components in a Spring Boot Project?

  1. Create a Web Project using Spring Inializr or IntelliJ Spring Plugins.
  2. Add Web framework support using IDE. It may create a directory as src/main/web/WEB-INF
  3. Rename the directory from web to webapp
  4. Create the view components like JSPs at src/main/webapp/WEB-INF/views/

  5. Define following properties in application.properties

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

src/main/web/WEB-INF/views/hello.jsp

will not be found by Spring Boot. As a Spring Boot convention you should put your views under resources folder:

src/main/resources/templates/...

And for your CSS:

src/main/resources/static/...

And if you are using Spring Boot, then it's a good idea to use the project initializer: https://start.spring.io/ from there choose what view technology you want, and Spring Boot will add its dependencies for you, so you don't need to add them or configure them yourself(step 3).

I tried the suggested changes and few more P&Cs, but it didn't fly though.
