Shiro框架--将Shrio的session改成HTTPSession数据

重写 FormAuthenticationFilter类 的 onLoginSuccess（）方法即可

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;

public class ShiroFormAuthenticationFilter extends FormAuthenticationFilter {

    @Override
    protected boolean onLoginSuccess(AuthenticationToken token, Subject subject, ServletRequest request,
            ServletResponse response) throws Exception {
        //获取身份里面的用户信息
        Object user = subject.getPrincipal();
        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        HttpSession session = httpServletRequest.getSession();
        session.setAttribute("user", user);

        return super.onLoginSuccess(token, subject, httpServletRequest, response);
    }

}
