使用GSON、Springboot响应Angular前端的JSON格式字符串

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.8</version>
</dependency>

import com.google.gson.Gson;

@RestController
public class MyController {
    
    @GetMapping("/data")
    public String getData() {
        MyDataObject data = new MyDataObject();
        // 设置data对象的属性
        
        Gson gson = new Gson();
        String json = gson.toJson(data);
        
        return json;
    }
}

import { HttpClient } from '@angular/common/http';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit {
  
  data: any;
  
  constructor(private http: HttpClient) { }
  
  ngOnInit() {
    this.http.get('/data').subscribe(response => {
      this.data = response;
      // 处理返回的数据
    });
  }
}
