,可以通过以下步骤实现:
以下是一个示例代码:
Spring Boot后端代码:
// Student.java
@Entity
public class Student {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
private int age;
// getters and setters
}
// StudentRepository.java
@Repository
public interface StudentRepository extends JpaRepository<Student, Long> {
// 可以定义一些查询方法
}
// StudentService.java
@Service
public class StudentService {
@Autowired
private StudentRepository studentRepository;
// 可以定义一些业务逻辑方法
}
// StudentController.java
@RestController
@RequestMapping("/students")
public class StudentController {
@Autowired
private StudentService studentService;
@GetMapping
public List<Student> getAllStudents() {
return studentService.getAllStudents();
}
}
Angular前端代码:
// student.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
import { Student } from './student.model';
@Injectable({
providedIn: 'root'
})
export class StudentService {
private apiUrl = 'http://localhost:8080/students';
constructor(private http: HttpClient) { }
getAllStudents(): Observable<Student[]> {
return this.http.get<Student[]>(this.apiUrl);
}
}
// student.component.ts
import { Component, OnInit } from '@angular/core';
import { Student } from './student.model';
import { StudentService } from './student.service';
@Component({
selector: 'app-student',
templateUrl: './student.component.html',
styleUrls: ['./student.component.css']
})
export class StudentComponent implements OnInit {
students: Student[];
constructor(private studentService: StudentService) { }
ngOnInit(): void {
this.studentService.getAllStudents().subscribe(students => {
this.students = students;
// 调用图表库生成图表
});
}
}
// student.component.html
<div *ngFor="let student of students">
<p>{{ student.name }}</p>
<p>{{ student.age }}</p>
</div>
请注意,以上代码仅为示例,实际项目中可能需要根据具体需求进行修改和扩展。另外,图表库的使用方法和配置可能因库而异,请参考相应的文档和示例。
