7)HttpOnly，如果在Cookie中设置了"HttpOnly"属性，那么通过程序(JS脚本、Applet等)将无法读取到Cookie信息。
Cookie上直接设置HttpOnly属性
https://blog.csdn.net/jinming1109/article/details/80281380
1.需要在web.xml中配置过滤器
<!-- cookie添加HttpOnly属性 -->
<filter>
<filter-name>CookieFilter</filter-name>
<filter-class>文件目录.CookieFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CookieFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2.java文件
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class CookieFilter implements Filter {
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse resp = (HttpServletResponse) response;
Cookie[] cookies = req.getCookies();
if (cookies != null) {
Cookie cookie = cookies[0];
if (cookie != null) {
/*
* cookie.setMaxAge(3600); cookie.setSecure(true); resp.addCookie(cookie);
*/
// Servlet 2.5不支持在Cookie上直接设置HttpOnly属性
String value = cookie.getValue();
StringBuilder builder = new StringBuilder();
builder.append("JSESSIONID=" + value + "; ");
builder.append("Secure; ");
builder.append("HttpOnly; ");
Calendar cal = Calendar.getInstance();
cal.add(Calendar.HOUR, 1);
Date date = cal.getTime();
Locale locale = Locale.CHINA;
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss", locale);
builder.append("Expires=" + sdf.format(date));
resp.setHeader("Set-Cookie", builder.toString());
}
}
chain.doFilter(req, resp);
}
public void destroy() {
}
public void init(FilterConfig arg0) throws ServletException {
}
}
