There was an unexpected error (404 Not Found) JSP and Spring Boot

When I try to translate a project into Spring Boot, I get an error-I can not understand what I did wrong. The suffix and prefix added to the property-file, tried to change the location of jsp,debager shows that in the controller's method comes. What have I done wrong? I will be grateful for any help

Error:

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.

Sping Security configuration: (Just in case)

package com.solopov.hillel.uquiz.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

import javax.sql.DataSource;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Autowired
    DataSource dataSource;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.jdbcAuthentication().dataSource(dataSource).passwordEncoder(new BCryptPasswordEncoder())
            .usersByUsernameQuery("select login,password,true from user where login=?")
             .authoritiesByUsernameQuery("select login, role from user where login=?");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http    .authorizeRequests()
                .antMatchers("/auth", "/reg","/welcomepage").permitAll()
                .antMatchers("/admin/**").hasAuthority("admin")
                .anyRequest().authenticated().and()
                .formLogin()
                .loginPage("/auth").usernameParameter("login")
                .permitAll()
                .and()
                .logout().logoutSuccessUrl("/auth")
                .and().csrf().disable();
    }
}

Method of Controller:

@RequestMapping(method = GET, value = "/auth")
    public String authorization() {
        return "Authorization";
    }

Start class:

@SpringBootApplication
public class UquizApplication {

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