Spring Boot - multi module maven doesn't see resources and JSP files under IntelliJ Ultimate

In this short article, we would like to show how in a proper way configure IntelliJ Ultimate IDE when we use multi-module maven project and we have a problem with access to resources and *.jsp files in Spring Boot Application.

Quick solution:

Set working directory for run module:

1. go to Run/Debug Configurations:

Copy

xxxxxxxxxx

 

1

Run -> Edit Configurations... -> Spring Boot -> [my spring boot application] -> Configuration -> Environment

2. set Working directory as: $MODULE_WORKING_DIR$

When we use maven modules in the project and the application is run from:

• the command line, everything works well
  Note: we run java -jar /path/to/application.jar
• IntelliJ IDE everything works well but it is impossible to:
  • use *.jsp views with controllers that are needed when we use Tomcat as a server,
  • read resources, e.g.
    Copy

    xxxxxxxxxx

     

    1

    @Autowired

    2

    ResourceLoader resourceLoader;

    3

    ​

    4

    ...

    5

    ​

    6

    Resource someResource = resourceLoader.getResource("some_resource.txt");

     

It is necessary to select the correct working directory for the run module.

Simple steps:

1. click to Run -> Edit Configurations... menu,
2. go to Spring Boot -> [my spring boot application] section in the left tree,
3. go to Configuration tab,
4. go to Environment configuration,
5. set Working directory as $MODULE_WORKING_DIR$,
6. accept all changes
