Spring Boot project shows the Login page

Question

I created a Spring boot project with the Spring initializer and only have the starter code so far.

The sample code

@SpringBootApplication public class EcommerceApplication {      public static void main(String[] args) {         SpringApplication.run(EcommerceApplication.class, args);     } }   @Controller @RequestMapping(value = "/") public class HomeController {      @GetMapping     public String index() {         return "index";     } } 

I expect it to return the index.html page from the templates folder. Instead, I'm redirected to the http://localhost:8080/login address and asked for the username/ password. In the application.properties file, I tried to use the configuration of,

server.port=8080 spring.application.name=Bootstrap Spring Boot spring.thymeleaf.cache=false spring.thymeleaf.enabled=true  spring.thymeleaf.prefix=classpath:/templates/ spring.thymeleaf.suffix=.html spring.datasource.driver-class-name=org.h2.Driver spring.datasource.url=jdbc:h2:mem:bootapp;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE spring.datasource.username=testuser spring.datasource.password=testpassword server.error.path=/error server.error.whitelabel.enabled=false  

I tried to login with the username testuser and the password testpassword. This doesn't work out.

I use the following pom.xml in the project,

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Whats the issue here?

Answer 1

If you don't want login page (from Spring-Security) remove the following dependency from your pom.xml

<dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-security</artifactId> </dependency> 

Or if you want to use the Spring-Security then on console it will display the default password like below :

Using default security password: ce6c3d39-8f20-4a41-8e01-803166bb99b6 

the default username will be user

Answer 2

That is the default behavior. to change this, you have a few options:

You can remove the Spring Boot Security dependency:

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> 

You can desable autoconfiguration. To do so; in your main class, to: @SpringBootApplication append: (exclude = { SecurityAutoConfiguration.class }) so that it looks like:

   @SpringBootApplication(exclude = { SecurityAutoConfiguration.class })    public static void main(String[] args) {             SpringApplication.run(SpringBootSecurityApplication.class, args);         }     } 

you can also do this from the application.properties file
