Java Subject.isRemembered方法代码示例

import org.apache.shiro.subject.Subject; //导入方法依赖的package包/类
@Override
protected boolean isAccessAllowed(ServletRequest request,
		ServletResponse response, Object mappedValue) {
	Subject subject = getSubject(request, response);

	// 如果 isAuthenticated 为 false 证明不是登录过的，同时 isRememberd 为true 证明是没登陆直接通过记住我功能进来的
	if (!subject.isAuthenticated() && subject.isRemembered()) {
		// 获取session的USERSESSION属性来看session是不是空的
		if(null == ShiroAuthenticationManager.getSessionAttribute(ShiroUtils.USERSESSION))
		{
			// 初始化
			UserEntity userEntity = (UserEntity) subject.getPrincipal();
			ShiroAuthenticationManager.setSessionAttribute(ShiroUtils.USERSESSION, userEntity);
		}
	}

	// 这个方法本来只返回 subject.isAuthenticated() 现在我们加上 subject.isRemembered()
	// 让它同时也兼容remember这种情况
	return subject.isAuthenticated() || subject.isRemembered();
}
