Key Points

...

Comparable to the run sub-command, the build sub-command is translated to the proper Maven or Gradle command with the correct build goal:

just build [--quick] [--skip-test] <buildTarget>

The quick option skips tests, document generation and checks such as formatting and static analysis. Just offers several buildTarget options to create a (native) application or a (native) Docker image: jar, native, image and native-image.

...

Just may be installed on MacOs with Homebrew:

brew install maciejwalkowiak/brew/just

...

scoop bucket add maciejwalkowiak https://github.com/maciejwalkowiak/scoop-just.git
scoop install just

Alternatively, the application may be installed manually on macOS, Windows or Linux, for example via the Linux command:

curl -Lo just.zip https://github.com/maciejwalkowiak/just/releases/latest/download/just-0.12.0-linux-x86_64.zip && unzip just.zip && chmod +x just && sudo mv just /usr/local/bin/just && just help

The help sub-command may be used to verify the installation.

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:

...

• 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

Testing is an integral part of software development. It ensures that your Spring Boot applications work as expected and continue to do so as they evolve. In this article, we’ll explore how to test Spring Boot applications using best practices and tools.

Why Testing Matters

Testing is crucial for several reasons:

1. Reliability: It ensures your application performs correctly and reliably.
2. Bug Detection: It helps identify and fix issues early in development.
3. Refactoring: It allows for code refactoring with confidence so existing functionality won’t break.
4. Documentation: Well-written tests serve as living documentation for your code.

Types of Testing

Spring Boot applications can be tested at various levels, including:

1. Unit Testing: Testing individual components, such as classes or methods, in isolation.
2. Integration Testing: Verifying that different components or services work correctly together.
3. Functional Testing: Testing the application’s functionality from the user’s perspective.
4. End-to-End Testing: Testing the entire application, including its external dependencies, in a production-like environment.
