基于 Spring Boot 3 与 React 的 Java 学生信息管理系统从入门到精通实操指南-阿里云开发者社区

以下是使用最新Java技术构建的学生信息管理系统的实操内容，包含详细的技术方案和代码说明：

Java学生信息管理系统实操指南（基于Spring Boot 3 + React）

技术栈选择

后端框架：Spring Boot 3.0（集成Spring Security、Spring Data JPA）
前端框架：React 18 + TypeScript
数据库：PostgreSQL 15 + Redis 7
容器化：Docker + Kubernetes
API规范：RESTful + OpenAPI 3.0
构建工具：Maven 3.9 + Vite 4

一、后端开发实操

1. 项目初始化

使用Spring Initializr创建基础项目，添加以下依赖：

dependencies {
   
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-security'
    implementation 'org.springframework.boot:spring-boot-starter-validation'
    implementation 'org.springdoc:springdoc-openapi-starter-webmvc-ui:2.1.0'
    runtimeOnly 'org.postgresql:postgresql'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.springframework.security:spring-security-test'
}

2. 领域模型设计

创建Student实体类，使用JPA注解映射数据库表：

@Entity
@Table(name = "students")
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class Student {
   
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @NotBlank(message = "姓名不能为空")
    @Size(max = 50)
    private String name;

    @NotNull(message = "年龄不能为空")
    @Min(1)
    @Max(100)
    private Integer age;

    @Email(message = "邮箱格式不正确")
    @Size(max = 100)
    private String email;

    @CreationTimestamp
    private LocalDateTime createTime;

    @UpdateTimestamp
    private LocalDateTime updateTime;
}

3. 数据访问层实现

使用Spring Data JPA的JpaRepository接口：

public interface StudentRepository extends JpaRepository<Student, Long> {
   
    List<Student> findByNameContaining(String name);
}

4. 服务层实现

添加业务逻辑和事务管理：

@Service
@Transactional
public class StudentService {
   
    private final StudentRepository repository;

    public StudentService(StudentRepository repository) {
   
        this.repository = repository;
    }

    public Student createStudent(Student student) {
   
        return repository.save(student);
    }

    public List<Student> searchStudents(String name) {
   
        return repository.findByNameContaining(name);
    }

    public void deleteStudent(Long id) {
   
        repository.deleteById(id);
    }

    // 其他业务方法...
}

5. REST API开发

使用Spring MVC创建API接口：

@RestController
@RequestMapping("/api/students")
@CrossOrigin(origins = "http://localhost:5173")
public class StudentController {
   
    private final StudentService service;

    public StudentController(StudentService service) {
   
        this.service = service;
    }

    @PostMapping
    public ResponseEntity<Student> create(@Valid @RequestBody Student student) {
   
        Student saved = service.createStudent(student);
        return ResponseEntity.status(HttpStatus.CREATED).body(saved);
    }

    @GetMapping
    public ResponseEntity<List<Student>> search(@RequestParam(required = false) String name) {
   
        List<Student> students = service.searchStudents(name);
        return ResponseEntity.ok(students);
    }

    @DeleteMapping("/{id}")
    public ResponseEntity<Void> delete(@PathVariable Long id) {
   
        service.deleteStudent(id);
        return ResponseEntity.noContent().build();
    }

    // 其他API方法...
}

6. 安全配置（JWT认证）

配置Spring Security和JWT：

@Configuration
@EnableWebSecurity
public class SecurityConfig {
   
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
   
        http
            .csrf().disable()
            .authorizeRequests()
                .antMatchers("/api/auth/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
            .addFilterBefore(jwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);

        return http.build();
    }

    @Bean
    public JwtAuthenticationFilter jwtAuthenticationFilter() {
   
        return new JwtAuthenticationFilter();
    }

    // 其他安全配置...
}

二、前端开发实操

1. 创建React项目

使用Vite初始化项目：

npm create vite@latest client -- --template react-ts
cd client
npm install axios react-router-dom @tanstack/react-query

2. API客户端封装

使用Axios和React Query：

// src/api/studentApi.ts
import axios from 'axios';
import {
    useQuery, useMutation } from '@tanstack/react-query';

const apiClient = axios.create({
   
  baseURL: 'http://localhost:8080/api',
  headers: {
   
    'Content-Type': 'application/json',
  },
});

export const useGetStudents = (name?: string) => {
   
  return useQuery({
   
    queryKey: ['students', name],
    queryFn: () => 
      apiClient.get('/students', {
    params: {
    name } }).then(res => res.data),
  });
};

export const useCreateStudent = () => {
   
  return useMutation({
   
    mutationFn: (student: any) => 
      apiClient.post('/students', student).then(res => res.data),
  });
};

3. 组件开发 - 学生列表

// src/components/StudentList.tsx
import { useGetStudents } from '../api/studentApi';
import { Table, Button } from 'antd';

const StudentList = ({ searchTerm }: { searchTerm?: string }) => {
  const { data: students, isLoading, error } = useGetStudents(searchTerm);

  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;

  const columns = [
    { title: 'ID', dataIndex: 'id' },
    { title: '姓名', dataIndex: 'name' },
    { title: '年龄', dataIndex: 'age' },
    { title: '邮箱', dataIndex: 'email' },
    { title: '操作', render: (_, record) => (
      <Button danger onClick={() => handleDelete(record.id)}>
        删除
      </Button>
    )}
  ];

  return <Table dataSource={students} columns={columns} rowKey="id" />;
};

4. 表单组件

// src/components/StudentForm.tsx
import { Form, Input, Button, Select, notification } from 'antd';
import { useCreateStudent } from '../api/studentApi';

const StudentForm = () => {
  const { mutate, isLoading } = useCreateStudent();
  const [form] = Form.useForm();

  const onFinish = (values: any) => {
    mutate(values, {
      onSuccess: () => {
        notification.success({ message: '创建成功' });
        form.resetFields();
      },
      onError: (err: any) => {
        notification.error({ message: '创建失败', description: err.message });
      },
    });
  };

  return (
    <Form form={form} onFinish={onFinish}>
      <Form.Item 
        name="name" 
        rules={[{ required: true, message: '请输入姓名' }]}
      >
        <Input placeholder="姓名" />
      </Form.Item>
      <Form.Item 
        name="age" 
        rules={[{ required: true, message: '请输入年龄' }]}
      >
        <Input.Number placeholder="年龄" />
      </Form.Item>
      <Form.Item 
        name="email" 
        rules={[{ required: true, message: '请输入邮箱' }, { type: 'email' }]}
      >
        <Input placeholder="邮箱" />
      </Form.Item>
      <Form.Item>
        <Button type="primary" htmlType="submit" loading={isLoading}>
          提交
        </Button>
      </Form.Item>
    </Form>
  );
};

三、容器化部署

1. Dockerfile（后端）

# 基础镜像
FROM openjdk:17-jdk-slim

# 设置工作目录
WORKDIR /app

# 复制依赖文件
COPY mvnw .
COPY .mvn .mvn
COPY pom.xml .

# 下载依赖
RUN ./mvnw dependency:go-offline -B

# 复制源代码
COPY src ./src

# 构建应用
RUN ./mvnw package -DskipTests

# 暴露端口
EXPOSE 8080

# 启动应用
CMD ["java", "-jar", "target/student-management-0.0.1-SNAPSHOT.jar"]

2. Docker Compose配置

version: '3.8'

services:
  db:
    image: postgres:15
    volumes:
      - postgres-data:/var/lib/postgresql/data
    environment:
      POSTGRES_USER: admin
      POSTGRES_PASSWORD: password
      POSTGRES_DB: student_db
    ports:
      - "5432:5432"

  redis:
    image: redis:7
    ports:
      - "6379:6379"

  backend:
    build: ./backend
    ports:
      - "8080:8080"
    depends_on:
      - db
      - redis
    environment:
      SPRING_DATASOURCE_URL: jdbc:postgresql://db:5432/student_db
      SPRING_DATASOURCE_USERNAME: admin
      SPRING_DATASOURCE_PASSWORD: password
      SPRING_REDIS_HOST: redis

  frontend:
    build: ./frontend
    ports:
      - "5173:80"
    depends_on:
      - backend

volumes:
  postgres-data:

四、测试与监控

1. 单元测试（后端）

@SpringBootTest
class StudentServiceTest {
   
    @Autowired
    private StudentService service;

    @Autowired
    private StudentRepository repository;

    @Test
    void testCreateStudent() {
   
        Student student = Student.builder()
            .name("测试学生")
            .age(20)
            .email("test@example.com")
            .build();

        Student saved = service.createStudent(student);

        assertNotNull(saved.getId());
        assertEquals("测试学生", saved.getName());

        // 验证数据库中是否存在
        assertTrue(repository.existsById(saved.getId()));
    }
}

2. 集成测试（前端）

import {
    render, screen } from '@testing-library/react';
import {
    StudentList } from './StudentList';
import {
    QueryClient, QueryClientProvider } from '@tanstack/react-query';

test('renders student list', async () => {
   
  const queryClient = new QueryClient();
  const mockStudents = [
    {
    id: 1, name: '张三', age: 20, email: 'zhangsan@example.com' },
  ];

  jest.spyOn(queryClient, 'fetchQuery').mockResolvedValue(mockStudents);

  render(
    <QueryClientProvider client={
   queryClient}>
      <StudentList />
    </QueryClientProvider>
  );

  await screen.findByText('张三');
  expect(screen.getByText('张三')).toBeInTheDocument();
});

五、项目部署与扩展
