create new class 

add this code 


import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
@EnableWebMvc
public class CrossOriginRequestFilter implements WebMvcConfigurer
{
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedMethods("GET", "POST","PUT","DELETE");
    }
}

=================================================

then under web config or security config

check my code at line 68 and disable cross



import it.ibs.tourismsquare.config.jwt.JwtAuthenticationEntryPoint;
import it.ibs.tourismsquare.config.jwt.JwtRequestFilter;
import it.ibs.tourismsquare.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.SecurityFilterChain;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig {

    @Autowired
    private JwtAuthenticationEntryPoint jwtAuthenticationEntryPoint;

    @Autowired
    private UserService jwtUserDetailsService;

    @Autowired
    private JwtRequestFilter jwtRequestFilter;

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    protected SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {

        return http
               .cors().and().csrf().disable().authorizeRequests(
                        auth -> auth.antMatchers("/", "/auth/**")
                                .permitAll()
                ).authorizeRequests(
                        auth -> auth.anyRequest().authenticated() //antMatchers("/api/**")
                ).exceptionHandling().authenticationEntryPoint(jwtAuthenticationEntryPoint).and().sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS).and().addFilterBefore(jwtRequestFilter, UsernamePasswordAuthenticationFilter.class).build();
    }
}
