Hello!

I have question about spring boot validation in Todo project.

public String addNewTodo(ModelMap modelMap, @Valid Todo todo, BindingResult bindingResult) {...}

If we change the position of the method parameters and put @Valid Todo todo before ModelMap modelMap, the validation not work correct and we don't see the error message in the form, but getting an exceptions in the browser. Why?

Thanks.

I have found an issue with HelloWorldService.js in which there's a commented code in executeBasicAuthenticationService this code will not comment make it uncommented otherwise it'll not sent the token.
We can comment code in retrieveHelloWorldPathVaraible instead.

export const retrieveHelloWorldPathVariable = (username, token) =>
apiClient.get(/hello-world/path-variable/${username}, {
/* headers: { //can be commented
Authorization: token,
}, */
});

export const executeBasicAuthenticationService = (token) =>
apiClient.get(/basicauth, /{ //Can't be commented
headers: { /Can't be commented
Authorization: token,
},/
});

I am not able to download Rest-API Todo project to integrate with React.

Having a problem using auth.requestMatchers its not accepting string as an argument, I tried using antMachers but was showing no response to the post request

`
public SecurityFilterChain securityFilterChain(HttpSecurity httpSecurity, HandlerMappingIntrospector introspector) throws Exception {

    return httpSecurity
            .authorizeHttpRequests(auth -> auth
                .requestMatchers("/authenticate").permitAll()
                .requestMatchers(PathRequest.toH2Console()).permitAll() // h2-console is a servlet and NOT recommended for a production
                .requestMatchers(HttpMethod.OPTIONS,"/**")
                .permitAll()
                .anyRequest()
                .authenticated())
            .csrf(AbstractHttpConfigurer::disable)
            .sessionManagement(session -> session.
                sessionCreationPolicy(SessionCreationPolicy.STATELESS))
            .oauth2ResourceServer(
                    OAuth2ResourceServerConfigurer::jwt)
            .httpBasic(
                    Customizer.withDefaults())
            .headers(header -> {header.
                frameOptions().sameOrigin();})
            .build();
}`

I want code of TODO App , I am not able to connect to database and that's why app is crashing.

I did the hands-on and added bootstrap but it showed no static resource error
After that I added this line to application properties then it worked
spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
