Apache Shiro是一个功能强大且灵活的开源安全框架,可以清晰地处理身份验证,授权,企业会话管理和加密。
验证用户以验证其身份
-
为用户执行访问控制,例如:
- 确定是否为用户分配了某个安全角色
- 确定是否允许用户执行某些操作
在任何环境中使用Session API,即使没有Web容器或EJB容器也是如此。
在身份验证,访问控制或会话生命周期内对事件做出反应。
聚合用户安全数据的1个或多个数据源,并将其全部显示为单个复合用户“视图”。
启用单点登录(SSO)功能
无需登录即可为用户关联启用“记住我”服务
Shiro针对Shiro开发团队所称的“应用程序安全的四大基石” - 身份验证,授权,会话管理和加密:身份验证:有时称为“登录”,这是证明用户是他们所说的人的行为。
授权:访问控制的过程,即确定“谁”可以访问“什么”。
会话管理:即使在非Web或EJB应用程序中,也可以管理特定于用户的会话。
密码学:使用加密算法保持数据安全,同时仍然易于使用。

配置AuthorizingRealm,创建SysUserRealm.java
/**
* @describe shiro认证
* @author Bertram.Wang
*/
@Component
public class SysUserRealm extends AuthorizingRealm {
@Autowired
private SysUserRepository sysUserRepository;
@Autowired
private SysUserService sysUserService;
/**
* 授权(验证权限时调用)
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
SysUser user = (SysUser) principals.getPrimaryPrincipal();
Integer userId = user.getId();
// 用户权限列表
Set permsSet = sysUserService.getAuthorityByUserId(userId);
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
info.setStringPermissions(permsSet);
return info;
}
/**
* 认证(登录时调用)
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
String username = (String) token.getPrincipal();
String password = new String((char[]) token.getCredentials());
// 查询用户信息
SysUser user = sysUserRepository.findOneByNameAndPassword(username, password);
// 账号不存在
if (user == null) {
throw new UnknownAccountException("账号或密码不正确");
}
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(userInfo, password, getName());
return info;
}
}
shiro配置类,主要是设置shiroFilter,securityManager, sessionManage等信息
自定义SessionManager

private static final String AUTHORIZATION = "Authorization";
private static final String REFERENCED_SESSION_ID_SOURCE = "Stateless request";
public MySessionManager() {

}
@Override
protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
String id = WebUtils.toHttp(request).getHeader(AUTHORIZATION);
//如果请求头中有 Authorization 则其值为sessionId
if (!StringUtils.isEmpty(id)) {
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, REFERENCED_SESSION_ID_SOURCE);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, id);
request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
return id;
} else {
//否则按默认规则从cookie取sessionId
return super.getSessionId(request, response);

限制规则:
- anon:准许直接访问
- authc:要求对请求用户进行身份验证,以便请求继续,如果没有验证,则强制用户通过将其定向到您配置的LoginUurl来登录。
- logout:接收到请求后,将立即注销当前正在执行的子节点,然后将它们重定向到已配置的redirecturl。
- perms: 如果当前用户具有映射值指定的权限,则允许访问;如果用户没有指定的所有权限,则拒绝访问

执行helloTest方法,
rest:{"code":20303,"message":"请先登录","time":1555320155};
先执行loginTest方法:
rest:{"code":0,"message":"成功","time":1555320426,"data":{"id":"a521dbf5-6a63-45d2-85de-95c121aeb0e9","host":"127.0.0.1","lastAccessTime":"2019-04-15T09:27:05.985+0000","timeout":1800000,"attributeKeys":["org.apache.shiro.subject.support.DefaultSubjectContext_AUTHENTICATED_SESSION_KEY","org.apache.shiro.subject.support.DefaultSubjectContext_PRINCIPALS_SESSION_KEY"],"startTimestamp":"2019-04-15T09:27:05.985+0000"}}
把rest.data.id替换sessionId,再执行helloTest方法:
