cors 오류 발생.

//Cors 설정
    @Bean
    public CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();

        configuration.setAllowedOriginPatterns(Collections.singletonList("*"));
        configuration.setAllowedMethods(List.of("GET", "POST", "PUT", "PATCH", "DELETE", "OPTIONS"));
        configuration.setAllowedHeaders(List.of("authorization", "content-type", "x-auth-token"));
        configuration.setExposedHeaders(Collections.singletonList("x-auth-token"));
        configuration.setAllowCredentials(true);

        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

말끔.

로그인 테스트

function main() 
{
    var data = {
        "userEmail" : "[email protected]",
        "userPassword" : "abcdefg"
    };
    $.ajax
    ({
        url: "<http://localhost:8080/userlogin>",
        data : JSON.stringify(data),
        type : "POST",
        contentType: "application/json; charset=utf-8",

        success: function(data) 
        {
            console.log(data);
        }
    });
}
