Configuration using lambdas

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests(authorizeRequests ->
                authorizeRequests
                    .antMatchers("/blog/**").permitAll()
                    .anyRequest().authenticated()
            )
            .formLogin(formLogin ->
                formLogin
                    .loginPage("/login")
                    .permitAll()
            )
            .rememberMe(withDefaults());
    }
}

Equivalent configuration without using lambdas

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/blog/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .rememberMe();
    }
}

Lambda DSL configuration tips

...

You may also configure WebFlux security using lambdas in a similar manner.
Below is an example configuration using lambdas.

@EnableWebFluxSecurity
public class SecurityConfig {

    @Bean
    SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        http
            .authorizeExchange(exchanges ->
                exchanges
                    .pathMatchers("/blog/**").permitAll()
                    .anyExchange().authenticated()
            )
            .httpBasic(withDefaults())
            .formLogin(formLogin ->
                formLogin
                    .loginPage("/login")
            );
        return http.build();
    }
}

Goals of the Lambda DSL

The Lambda DSL was created to accomplish to following goals:

jhipster-crud-developer.okta.com-Use React and Spring Boot to Build a Simple CRUD App.pdf file

React was designed to make it painless to create interactive UIs. Its state management is efficient and only updates components when your data changes. Component logic is written in JavaScript, meaning you can keep state out of the DOM and create encapsulated components.

Developers like CRUD (create, read, update, and delete) apps because they show a lot of the base functionality you need when creating an app. Once you have the basics of CRUD completed in an app, most of the client-server plumbing is finished, and you can move on to implementing the necessary business logic.

Today, I’ll show you how to create a basic CRUD app with Spring Boot and React. In this tutorial, I’ll use the OAuth 2.0 Authorization Code flow and package the React app in the Spring Boot app for production. At the same time, I’ll show you how to keep React’s productive workflow for developing locally.

You will need Java 17 and Node 16 installed to complete this tutorial.

• Create an API app with Spring Boot
  • Add a JPA domain model
• Create a React UI with Create React App
• Call your Spring Boot API and display the results
• Build a React GroupList component
• Add a React GroupEdit component
• Add authentication with Okta
  • Spring Security + OIDC
  • Create an OIDC app in Okta
  • Use Auth0 for OIDC
• Configure Spring Security for React and user identity
• Modify React to handle CSRF and be identity-aware
• Configure Maven to build and package React with Spring Boot
• Learn more about Spring Boot and React
