Pros of spring-boot

• Official Spring Boot repository, providing the core framework and documentation
• Extensive test coverage and continuous integration
• Regular updates and releases with detailed changelogs

Cons of spring-boot

• Steeper learning curve for beginners due to its comprehensive nature
• Less focus on practical examples and real-world use cases
• May be overwhelming for developers seeking quick, specific implementations

Code Comparison

spring-boot (Configuration class):

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

spring-boot-examples (HelloWorld controller):

@RestController
public class HelloWorldController {
    @RequestMapping("/hello")
    public String index() {
        return "Hello World";
    }
}

The spring-boot repository focuses on core framework code, while spring-boot-examples provides practical implementations and tutorials for various Spring Boot features. spring-boot is ideal for understanding the framework's internals and contributing to its development, whereas spring-boot-examples is better suited for learning and quick reference when building Spring Boot applications.

Pros of tutorials

• Broader scope, covering various Java frameworks and technologies beyond Spring Boot
• More comprehensive, with a larger number of examples and tutorials
• Regular updates and active community engagement

Cons of tutorials

• Can be overwhelming due to the vast amount of content
• May lack the focused, in-depth Spring Boot coverage found in spring-boot-examples

Code Comparison

spring-boot-examples:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

tutorials:

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Summary

Both repositories offer valuable resources for Java developers. spring-boot-examples provides a focused approach to Spring Boot, making it ideal for those specifically interested in this framework. tutorials, on the other hand, offers a wider range of topics and examples, catering to developers looking to explore various Java technologies.

The code comparison shows that both repositories use similar basic Spring Boot application structures, with tutorials demonstrating a more explicit configuration approach. Ultimately, the choice between these repositories depends on the developer's specific learning goals and preferences.

Pros of springboot-learning-example

• More comprehensive coverage of Spring Boot features, including advanced topics like Spring Cloud and microservices
• Better organized structure with clear categorization of examples
• More frequent updates and active maintenance

Cons of springboot-learning-example

• Less beginner-friendly, with fewer explanations and comments in the code
• Smaller community engagement, with fewer stars and forks on GitHub
• Some examples may be outdated or not aligned with the latest Spring Boot best practices

Code Comparison

spring-boot-examples:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

springboot-learning-example:

@SpringBootApplication
@EnableScheduling
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

The main difference in the code snippets is that springboot-learning-example includes the @EnableScheduling annotation, demonstrating more advanced configuration options in its examples.

Pros of SpringBoot-Learning

• More comprehensive coverage of Spring Boot topics
• Better organization with separate branches for different Spring Boot versions
• Includes more advanced topics like microservices and cloud deployment

Cons of SpringBoot-Learning

• Less frequent updates compared to spring-boot-examples
• Fewer contributors, potentially limiting diverse perspectives
• Some examples may be outdated for the latest Spring Boot versions

Code Comparison

SpringBoot-Learning:

@SpringBootApplication
@EnableDiscoveryClient
public class ServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServiceApplication.class, args);
    }
}

spring-boot-examples:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

The SpringBoot-Learning example includes @EnableDiscoveryClient, demonstrating integration with service discovery, while spring-boot-examples keeps it simpler with just the basic @SpringBootApplication annotation.

Both repositories offer valuable resources for learning Spring Boot, with SpringBoot-Learning providing more depth and spring-boot-examples offering a broader range of simpler examples. The choice between them depends on the learner's experience level and specific learning goals.

Pros of spring-boot-demo

• More comprehensive coverage of Spring Boot features and integrations
• Better organized project structure with clear module separation
• More frequent updates and active maintenance

Cons of spring-boot-demo

• Potentially overwhelming for beginners due to its extensive scope
• Less focused on basic Spring Boot concepts compared to spring-boot-examples

Code Comparison

spring-boot-demo:

@SpringBootApplication
@EnableScheduling
@EnableAsync
public class SpringBootDemoTaskApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootDemoTaskApplication.class, args);
    }
}

spring-boot-examples:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

The spring-boot-demo example includes additional annotations for enabling scheduling and asynchronous execution, demonstrating a more feature-rich approach. In contrast, the spring-boot-examples code showcases a simpler, more straightforward implementation focusing on core Spring Boot functionality.

Both repositories serve as valuable resources for learning Spring Boot, with spring-boot-demo offering a wider range of advanced topics and integrations, while spring-boot-examples provides a more accessible entry point for newcomers to the framework.

Pros of mall

• Comprehensive e-commerce solution with a wide range of features
• Well-structured and modular architecture for scalability
• Detailed documentation and deployment guides

Cons of mall

• Steeper learning curve due to its complexity
• May be overkill for simpler projects or learning purposes
• Requires more resources to run and maintain

Code comparison

mall:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity.csrf()
                    .disable()
                    .sessionManagement()
                    .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                    .and()
                    .authorizeRequests()
                    .antMatchers("/admin/**").hasRole("ADMIN")
                    .anyRequest().authenticated();
    }
}

spring-boot-examples:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/", "/home").permitAll()
            .anyRequest().authenticated()
            .and()
            .formLogin()
            .loginPage("/login")
            .permitAll();
    }
}

The mall project provides a more comprehensive security configuration, including CSRF protection and session management, while spring-boot-examples offers a simpler setup focused on basic authentication and authorization.
