将Java API中的byte[]渲染为Angular 2中的图像

import java.util.Base64;

public class ImageRenderer {
    public static String renderImage(byte[] imageBytes) {
        String base64Image = Base64.getEncoder().encodeToString(imageBytes);
        return base64Image;
    }
}

<img src="data:image/png;base64, {{ base64Image }}" alt="Image">

import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Component({
  selector: 'app-image',
  templateUrl: './image.component.html',
  styleUrls: ['./image.component.css']
})
export class ImageComponent implements OnInit {
  base64Image: string;

  constructor(private http: HttpClient) { }

  ngOnInit() {
    this.getImage();
  }

  getImage() {
    this.http.get('http://your-java-api-url')
      .subscribe((response: any) => {
        this.base64Image = response.base64Image;
      });
  }
}
