Pros of Spring Boot

• Official Spring Boot repository with extensive documentation and community support
• Regularly updated with new features, bug fixes, and security patches
• Comprehensive test coverage and production-ready code

Cons of Spring Boot

• Larger codebase, which may be overwhelming for beginners
• Focuses on core functionality rather than specific use cases or examples
• Steeper learning curve for those new to Spring ecosystem

Code Comparison

Spring Boot (core functionality):

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

Spring Boot Demo (example implementation):

@SpringBootApplication
@RestController
public class DemoApplication {
    @GetMapping("/hello")
    public String hello() {
        return "Hello, Spring Boot!";
    }

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

Summary

Spring Boot is the official repository, offering a robust and well-maintained framework for building Spring applications. It provides extensive documentation and regular updates but may be challenging for beginners due to its comprehensive nature.

Spring Boot Demo, on the other hand, focuses on providing practical examples and use cases, making it easier for developers to understand and implement specific features. However, it may not cover all aspects of Spring Boot or receive updates as frequently as the official repository.

Pros of springboot-learning-example

• More comprehensive coverage of Spring Boot features, including advanced topics
• Better organized structure with clear categorization of examples
• Includes detailed explanations and comments in Chinese, beneficial for Chinese-speaking developers

Cons of springboot-learning-example

• Less frequently updated compared to spring-boot-demo
• Fewer integration examples with popular third-party libraries
• Some examples may be outdated due to the project's age

Code Comparison

spring-boot-demo:

@SpringBootApplication
@MapperScan(basePackages = {"com.xkcoding.mybatis.mapper"})
public class MybatisApplication {
    public static void main(String[] args) {
        SpringApplication.run(MybatisApplication.class, args);
    }
}

springboot-learning-example:

@SpringBootApplication
@MapperScan("com.didispace.mybatis.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Both examples demonstrate similar basic setup for a Spring Boot application with MyBatis integration. The main difference lies in the package structure and naming conventions used in each project.

Pros of spring-boot-examples

• More comprehensive coverage of Spring Boot features and integrations
• Better organized structure with clear categorization of examples
• Includes examples for Spring Cloud and microservices architecture

Cons of spring-boot-examples

• Less frequent updates compared to spring-boot-demo
• Some examples may be outdated or not compatible with the latest Spring Boot version
• Lacks some modern features and integrations present in spring-boot-demo

Code Comparison

spring-boot-examples:

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

spring-boot-demo:

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

The code comparison shows that spring-boot-demo includes additional annotations and configurations, such as @EnableScheduling, which demonstrates its focus on more specific use cases and advanced features.

Both repositories serve as valuable resources for learning Spring Boot, with spring-boot-examples offering a broader range of examples and spring-boot-demo providing more up-to-date and specialized implementations.

Pros of SpringBoot-Learning

• More comprehensive coverage of Spring Boot topics, including advanced concepts
• Better organized structure with clear categorization of examples
• Regularly updated with new Spring Boot features and best practices

Cons of SpringBoot-Learning

• Less focus on practical, real-world application scenarios
• Fewer integration examples with third-party libraries and tools
• May be overwhelming for beginners due to its extensive content

Code Comparison

SpringBoot-Learning:

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

spring-boot-demo:

@SpringBootApplication
@MapperScan(basePackages = "com.xkcoding.mybatis.mapper")
public class MybatisApplication {
    public static void main(String[] args) {
        SpringApplication.run(MybatisApplication.class, args);
    }
}

The code comparison shows that SpringBoot-Learning focuses on core Spring Boot features like scheduling, while spring-boot-demo demonstrates integration with specific technologies like MyBatis.

Both repositories offer valuable resources for learning Spring Boot, with SpringBoot-Learning providing a more comprehensive guide and spring-boot-demo offering more practical, focused examples. The choice between them depends on the learner's experience level and specific learning goals.

Pros of JeecgBoot

• More comprehensive enterprise-level solution with built-in low-code platform
• Extensive documentation and active community support
• Includes advanced features like code generation and workflow management

Cons of JeecgBoot

• Steeper learning curve due to its complexity
• May be overkill for smaller projects or simple applications
• Less flexibility for customization compared to a bare-bones Spring Boot setup

Code Comparison

JeecgBoot (using its code generation feature):

@RestController
@RequestMapping("/demo")
@Slf4j
public class DemoController {
    @Autowired
    private IDemoService demoService;
    
    @GetMapping(value = "/list")
    public Result<?> list(DemoEntity demo, @RequestParam(name="pageNo", defaultValue="1") Integer pageNo, @RequestParam(name="pageSize", defaultValue="10") Integer pageSize) {
        return Result.OK(demoService.list(demo, pageNo, pageSize));
    }
}

spring-boot-demo (basic REST controller):

@RestController
@RequestMapping("/api")
public class DemoController {
    @GetMapping("/hello")
    public String hello(@RequestParam(value = "name", defaultValue = "World") String name) {
        return String.format("Hello, %s!", name);
    }
}

JeecgBoot offers more out-of-the-box functionality, while spring-boot-demo provides a simpler starting point for custom development.

Pros of mall

• More comprehensive e-commerce solution with frontend and backend components
• Includes advanced features like Redis caching and Elasticsearch integration
• Offers detailed documentation and deployment guides

Cons of mall

• Higher complexity and steeper learning curve
• May be overkill for simpler projects or learning purposes
• Requires more resources to run and maintain

Code Comparison

mall (PmsProductController.java):

@ApiOperation("Create product")
@RequestMapping(value = "/create", method = RequestMethod.POST)
@ResponseBody
public CommonResult create(@RequestBody PmsProductParam productParam) {
    int count = productService.create(productParam);
    if (count > 0) {
        return CommonResult.success(count);
    } else {
        return CommonResult.failed();
    }
}

spring-boot-demo (UserController.java):

@PostMapping("/user")
public ResponseEntity<User> createUser(@RequestBody User user) {
    User savedUser = userRepository.save(user);
    return ResponseEntity.ok(savedUser);
}

The mall project demonstrates a more structured approach with API documentation and custom result handling, while spring-boot-demo showcases a simpler, more straightforward implementation.
