SpringBoot 401 UnAuthorized even with out security

Just remove the the spring security dependency from pom.xml file. Worked for me :)..

In the current version of Spring Boot (v2.1.0.RELEASE), the easiest way to get rid of the security issues is to add "WebSecurityConfig.java" to your project as follows:

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@EnableWebSecurity
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
    }

}

Note of course that this removes protection against cross-site request forgery, so this is really only appropriate for simple read-only endpoints.

Try to add below lines in your application.properties file

security.basic.enable: false
security.ignored=/**

According to spring doc, use security.ignored=
