img的src地址是一个请求的方式来显示图片方法
1、jsp<img alt="test" src="getImg2.do">
2、controller
@RequestMapping("getImg2")
public void getImg2(HttpServletRequest request, HttpServletResponse response)
throws IOException {
FileInputStream fis = null;
OutputStream os = null;
try {
fis = new FileInputStream("d:/log.png");
os = response.getOutputStream();
int count = 0;
byte[] buffer = new byte;
while ((count = fis.read(buffer)) != -1) {
os.write(buffer, 0, count);
os.flush();
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
fis.close();
os.close();
} catch (IOException e) {
e.printStackTrace();
}
}
