一、普通spring mvc返回图片或网页到浏览器

@Controller @RequestMapping(value = "/image") public class ImageController { @RequestMapping(value = "/get") @ResponseBody public void getImage(HttpServletResponse response) throws IOException { File file = new File("D:/test.jpg"); FileInputStream inputStream = new FileInputStream(file); byte[] bytes = new byte[inputStream.available()]; response.setContentType("image/jpeg"); OutputStream out = response.getOutputStream(); out.write(result); out.flush(); //关闭响应输出流 out.close(); } }

二、spring boot

import org.springframework.http.MediaType; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import java.io.File; import java.io.FileInputStream; import java.io.IOException; @Controller @RequestMapping(value = "/image") public class ImageController { @RequestMapping(value = "/get",produces = MediaType.IMAGE_JPEG_VALUE) @ResponseBody public byte[] getImage() throws IOException { File file = new File("D:/test.jpg"); FileInputStream inputStream = new FileInputStream(file); byte[] bytes = new byte[inputStream.available()]; inputStream.read(bytes, 0, inputStream.available()); return bytes; } }

如果是网页的话，

produces = MediaType.TEXT_HTML
