<img>标签，显示服务器图片

D:/DevelopmentTool/apache-tomcat-8.5.14/webapps/pic/服务器该文件夹下存放了名字为001.jpg

的图片

HTML页面：

<img style="width: 550px" 

  src="project/manager/picture?name=001.png&time=${currentTime}">

说明：

project/manager是服务器controller的地址

@Controller@RequestMapping("project/manager/")

picture是controller里面往外写图片的方法的地址

@RequestMapping("picture")

time=${currentTime}是为了对付浏览器缓存，

${currentTime}是从服务器上传过来的当前系统时间的值

服务器controller写法：

@Controller@RequestMapping("project/manager/")public class ProjectManagerController extends BaseController {@RequestMapping("picture")public void upload( HttpServletResponse response,String name) {OutputStream os = null;FileInputStream fis = null;try {os = response.getOutputStream();fis = new FileInputStream("D:/DevelopmentTool/apache-tomcat-8.5.14/webapps/pic/"+name);byte[] buffer = new byte[1024];while(fis.read(buffer) != -1) {os.write(buffer);}}catch (Exception e){}finally {if(ValidateUtil.objectIsNotNull(os)){try {os.flush();os.close();fis.close();}catch (Exception e){}}}}

}
