Spring Boot在多模块项目中找不到jsp

Question

I'm using spring boot and I decided just for example sake to split my project into modules. I have 4 modules, web, service, repository, domain. All work okay except JSP, spring can't find these pages. But when I didn't split my project to modules it worked. I didn't change configuration.

This is my structure of web module

Runner is located in web module, Here it is:

@SpringBootApplication(scanBasePackages = "kz.epam.javalab.daimoncool")
public class WebApplication {

    public static void main(String[] args) {
        SpringApplication.run(WebApplication.class, args);
    }

}

This is my application.properties:

spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false

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

spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:orcl
spring.datasource.username=
spring.datasource.password=
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
spring.jpa.properties.hibernate.physical_naming_strategy=com.vladmihalcea.hibernate.type.util.CamelCaseToSnakeCaseNamingStrategy

spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username=
spring.mail.password=
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.ssl.trust=smtp.gmail.com

I would be happy if you can help me) And I repeat, that it works when there were no modules, without changing the configuration, just adding modules it doesn't work.

Result:

Also Intellij IDEA shows me that there is not view resolver for index.jsp, even though I add view resolver bean explicitly

Answer 1

I found the problem. I needed to change the working directory in intellij IDEA. Spring boot runner takes root path and then look for the jsp (in my case it was the parent project). But my runner was in web module, so I needed spring boot runner to change root path to web module (by changing the working directory), not to parent.
