This article discusses the development of a national consumption level ranking platform utilizing Java, Spring Boot, MyBatis, and Vue.js. The platform aims to provide a comprehensive view of consumption levels across different regions.

Backend Framework: Spring Boot

Spring Boot simplifies the process of building standalone, production-grade Spring-based applications. It follows the principle of convention over configuration, reducing the need for extensive boilerplate code. Spring Boot's embedded web servers like Tomcat, Undertow, or Jetty facilitate easy deployment of applications as executable JAR files. Additionally, it offers robust monitoring and management capabilities through Actuator endpoints.

Frontend Framework: Vue.js

Vue.js is a progressive JavaScript framework designed for building user interfaces and single-page applications. It features a reactive data binding system that enables seamless updates to the DOM. Vue's component-based architecture promotes reusability and modularity, making it easier to manage complex applications. The framework also boasts an active community and a wealth of plugins and tools.

Core Code Example

package com.platform;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
@MapperScan(basePackages = {"com.platform.dao"})
public class ConsumptionLevelApp extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(ConsumptionLevelApp.class);
    }
}

package com.platform.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.*;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.platform.entity.UserEntity;
import com.platform.service.UserService;
import com.platform.utils.ResponseUtil;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

@RestController
@RequestMapping("/api/user")
public class UserController {

    @Autowired
    private UserService userService;

    @PostMapping("/login")
    public ResponseUtil login(@RequestParam String username, @RequestParam String password) {
        QueryWrapper<userentity> wrapper = new QueryWrapper<>();
        wrapper.eq("account", username).eq("password", password);
        UserEntity user = userService.getOne(wrapper);
        if (user == null) {
            return ResponseUtil.fail("Invalid credentials");
        }
        return ResponseUtil.success(user);
    }

    @PostMapping("/register")
    @Transactional
    public ResponseUtil register(@RequestBody UserEntity user) {
        if (userService.existsByAccount(user.getAccount())) {
            return ResponseUtil.fail("User already exists");
        }
        userService.save(user);
        return ResponseUtil.success("Registration successful");
    }

    @GetMapping("/list")
    public ResponseUtil getUsers(@RequestParam int page, @RequestParam int size) {
        Page<userentity> userPage = userService.page(new Page<>(page, size));
        List<userentity> userList = userPage.getRecords();
        return ResponseUtil.success(userList);
    }
}
</userentity></userentity></userentity>

System Testing

The primary goal of system testing is to identify and rectify defects, ensuring the system meets the specified requirements. This involves functional testing to validate each module's behavior under various scenarios.

Testing Objectives

• To ensure the system functions correctly under different conditions.
• To enhance user experience by addressing potential issues proactively.
• To verify that the system adheres to the design specifications.

Functional Testing

Functional testing focuses on validating individual modules. Test cases are created based on user interactions and system responses. For example, the login functionality is tested by simulating user inputs and verifying the system's response.

Conclusion

Comprehensive system testing is crucial for ensuring the quality and reliability of the application. By conducting thorough tests, we can identify and fix issues before the system goes live, thereby improving its usability and performance.
