Java – Spring boot application.properties file does not complete code automatically

I created a spring project using Spring Initializr in the IntelliJ IDE.
When I try to modify the application.properties file, I realize that it doesn’t autocomplete the code, I mean, it doesn’t show options and show “Integer” like you type “In”.
Also, if I try to run the application, localhost:8080/index.html is redirected to http://localhost:8080/login

Any idea what the problem is?
Thanks

Just realized import lombok. Data; Also not highlighted, even if dependencies are set

First question:

… it does not autocomplete the code

You should make sure that your “Spring Boot” plugin is enabled. Seehere Learn how to manage plugins in Intellij IDEA.

Second question:

localhost:8080/index.html is redirected to http://localhost:8080/login

To resolve the redirect issue, you should remove the maven dependency on spring-starter-security (such as user9717940 described). However, it can be caused by other security-related dependencies, such as Oauth. Go to your Maven pom.xml file and look for something similar to the code snippet below and remove it from your dependencies section.

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-test</artifactId>
            <scope>test</scope>
        </dependency>
