一.说明
Shiro是一个安全框架,项目中主要用它做认证,授权,加密,以及用户的会话管理,虽然Shiro没有SpringSecurity功能更丰富,但是它轻量,简单,在项目中通常业务需求Shiro也都能胜任.
二.项目环境
MyBatis-Plus版本: 3.1.0
SpringBoot版本:2.1.5
JDK版本:1.8
Shiro版本:1.4
Shiro-redis插件版本:3.1.0
数据表(SQL文件在项目中):数据库中测试号的密码进行了加密,密码皆为123456
Maven依赖如下：

log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
二.编写项目基础类
用户实体,Dao,Service等在这里省略,请参考源码
编写Exception类来处理Shiro权限拦截异常
创建SHA256Util加密工具
创建Spring工具
/**
* @Description Spring上下文工具类
* @Author Sans
* @CreateTime 2019/6/17 13:40
*/
@Component
public class SpringUtil implements ApplicationContextAware {
private static ApplicationContext context;
/**
* Spring在bean初始化后会判断是不是ApplicationContextAware的子类
* 如果该类是,setApplicationContext()方法,会将容器中ApplicationContext作为参数传入进去
* @Author Sans
* @CreateTime 2019/6/17 16:58
*/
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
context = applicationContext;
}
/**
* 通过Name返回指定的Bean
* @Author Sans
* @CreateTime 2019/6/17 16:03
*/
public static T getBean(Class beanClass) {
return context.getBean(beanClass);
}
}
创建Shiro工具
/**
* @Description Shiro工具类
* @Author Sans
* @CreateTime 2019/6/15 16:11
*/
public class ShiroUtils {
/** 私有构造器 **/
private ShiroUtils(){}
private static RedisSessionDAO redisSessionDAO = SpringUtil.getBean(RedisSessionDAO.class);
/**
* 获取当前用户Session
* @Author Sans
* @CreateTime 2019/6/17 17:03
* @Return SysUserEntity 用户信息
*/
public static Session getSession() {
return SecurityUtils.getSubject().getSession();
}
/**
* 用户登出
* @Author Sans
* @CreateTime 2019/6/17 17:23
*/
public static void logout() {
SecurityUtils.getSubject().logout();
}
/**
* 获取当前用户信息
* @Author Sans
* @CreateTime 2019/6/17 17:03
* @Return SysUserEntity 用户信息
*/
public static SysUserEntity getUserInfo() {
return (SysUserEntity) SecurityUtils.getSubject().getPrincipal();
}
/**
* 删除用户缓存信息
* @Author Sans
* @CreateTime 2019/6/17 13:57
* @Param username 用户名称
* @Param isRemoveSession 是否删除Session
* @Return void
*/
public static void deleteCache(String username, boolean isRemoveSession){
//从缓存中获取Session
Session session = null;
Collection sessions = redisSessionDAO.getActiveSessions();
SysUserEntity sysUserEntity;
Object attribute = null;
for(Session sessionInfo : sessions){
//遍历Session,找到该用户名称对应的Session
attribute = sessionInfo.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);
if (attribute == null) {
continue;
}
sysUserEntity = (SysUserEntity) ((SimplePrincipalCollection) attribute).getPrimaryPrincipal();
if (sysUserEntity == null) {
continue;
}
if (Objects.equals(sysUserEntity.getUsername(), username)) {
session=sessionInfo;
}
}
if (session == null||attribute == null) {
return;
}
//删除session
if (isRemoveSession) {
redisSessionDAO.delete(session);
}
//删除Cache，在访问受限接口时会重新授权
DefaultWebSecurityManager securityManager = (DefaultWebSecurityManager) SecurityUtils.getSecurityManager();
Authenticator authc = securityManager.getAuthenticator();
((LogoutAware) authc).onLogout((SimplePrincipalCollection) attribute);
}
}
创建Shiro的SessionId生成器
三.编写Shiro核心类
创建Realm用于授权和认证
/**

* @Author Sans
* @CreateTime 2019/6/15 11:27
*/
public class ShiroRealm extends AuthorizingRealm {
@Autowired
private SysUserService sysUserService;
@Autowired
private SysRoleService sysRoleService;
@Autowired
private SysMenuService sysMenuService;
/**

* 用户进行权限验证时候Shiro会去缓存中找,如果查不到数据,会执行这个方法去查权限,并放入缓存中
* @Author Sans
* @CreateTime 2019/6/12 11:44
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
SysUserEntity sysUserEntity = (SysUserEntity) principalCollection.getPrimaryPrincipal();
//获取用户ID
Long userId =sysUserEntity.getUserId();
//这里可以进行授权和处理
Set rolesSet = new HashSet<>();
Set permsSet = new HashSet<>();
//查询角色和权限(这里根据业务自行查询)
List sysRoleEntityList = sysRoleService.selectSysRoleByUserId(userId);
for (SysRoleEntity sysRoleEntity:sysRoleEntityList) {
rolesSet.add(sysRoleEntity.getRoleName());
List sysMenuEntityList = sysMenuService.selectSysMenuByRoleId(sysRoleEntity.getRoleId());
for (SysMenuEntity sysMenuEntity :sysMenuEntityList) {
permsSet.add(sysMenuEntity.getPerms());
}
}
//将查到的权限和角色分别传入authorizationInfo中
authorizationInfo.setStringPermissions(permsSet);
authorizationInfo.setRoles(rolesSet);
return authorizationInfo;
}
/**
* 身份认证
* @Author Sans
* @CreateTime 2019/6/12 12:36
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
//获取用户的输入的账号.
String username = (String) authenticationToken.getPrincipal();
//通过username从数据库中查找 User对象，如果找到进行验证
//实际项目中,这里可以根据实际情况做缓存,如果不做,Shiro自己也是有时间间隔机制,2分钟内不会重复执行该方法
SysUserEntity user = sysUserService.selectUserByName(username);
//判断账号是否存在
if (user == null) {
throw new AuthenticationException();
}
//判断账号是否被冻结
if (user.getState()==null||user.getState().equals("PROHIBIT")){
throw new LockedAccountException();
}
//进行验证
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
user, //用户名
user.getPassword(), //密码
ByteSource.Util.bytes(user.getSalt()), //设置盐值
getName()
);
//验证成功开始踢人(清除缓存和Session)
ShiroUtils.deleteCache(username,true);
return authenticationInfo;
}
}
创建SessionManager类
创建ShiroConfig配置类

四.实现权限控制
Shiro可以用代码或者注解来控制权限,通常我们使用注解控制,不仅简单方便,而且更加灵活.Shiro注解一共有五个:
一般情况下我们在项目中做权限控制,使用最多的是RequiresPermissions和RequiresRoles,允许存在多个角色和权限,默认逻辑是AND,也就是同时拥有这些才可以访问方法,可以在注解中以参数的形式设置成OR
示例
使用顺序:Shiro注解是存在顺序的,当多个注解在一个方法上的时候,会逐个检查,知道全部通过为止,默认拦截顺序是:RequiresRoles->RequiresPermissions->RequiresAuthentication->
RequiresUser->RequiresGuest
示例
创建UserRoleController角色拦截测试类
/**
* @Description 角色测试
* @Author Sans
* @CreateTime 2019/6/19 11:38
*/
@RestController
@RequestMapping("/role")
public class UserRoleController {
@Autowired
private SysUserService sysUserService;
@Autowired
private SysRoleService sysRoleService;
@Autowired
private SysMenuService sysMenuService;
@Autowired
private SysRoleMenuService sysRoleMenuService;
/**

map.put("code",200);
map.put("msg","这里是只有管理员角色能访问的接口");
return map;
}

return map;
}
/**

* @Author Sans
* @CreateTime 2019/6/19 10:38
* @Return Map 返回结果
*/
@RequestMapping("/getLogout")
@RequiresUser
public Map getLogout(){
ShiroUtils.logout();
Map map = new HashMap<>();
map.put("code",200);
map.put("msg","登出");
return map;
}
}
创建UserMenuController权限拦截测试类
/**
* @Description 权限测试
* @Author Sans
* @CreateTime 2019/6/19 11:38
*/
@RestController
@RequestMapping("/menu")
public class UserMenuController {
@Autowired
private SysUserService sysUserService;
@Autowired
private SysRoleService sysRoleService;
@Autowired
private SysMenuService sysMenuService;
@Autowired
private SysRoleMenuService sysRoleMenuService;
/**

*/
@RequestMapping("/getUserInfoList")
@RequiresPermissions("sys:user:info")
public Map getUserInfoList(){
Map map = new HashMap<>();
List sysUserEntityList = sysUserService.list();
map.put("sysUserEntityList",sysUserEntityList);
return map;
}
/**
* 获取角色信息集合
* @Author Sans
* @CreateTime 2019/6/19 10:37

*/
@RequestMapping("/getRoleInfoList")

public Map getRoleInfoList(){
Map map = new HashMap<>();
List sysRoleEntityList = sysRoleService.list();
map.put("sysRoleEntityList",sysRoleEntityList);
return map;
}
/**
* 获取权限信息集合
* @Author Sans
* @CreateTime 2019/6/19 10:38
* @Return Map 返回结果
*/
@RequestMapping("/getMenuInfoList")
@RequiresPermissions("sys:menu:info")
public Map getMenuInfoList(){
Map map = new HashMap<>();
List sysMenuEntityList = sysMenuService.list();
map.put("sysMenuEntityList",sysMenuEntityList);
return map;
}
/**
* 获取所有数据
* @Author Sans
* @CreateTime 2019/6/19 10:38

*/
@RequestMapping("/getInfoAll")
@RequiresPermissions("sys:info:all")
public Map getInfoAll(){
Map map = new HashMap<>();
List sysUserEntityList = sysUserService.list();
map.put("sysUserEntityList",sysUserEntityList);
List sysRoleEntityList = sysRoleService.list();
map.put("sysRoleEntityList",sysRoleEntityList);
List sysMenuEntityList = sysMenuService.list();
map.put("sysMenuEntityList",sysMenuEntityList);
return map;
}
/**

* @Author Sans
* @CreateTime 2019/6/19 10:39
* @Param username 用户ID
* @Return Map 返回结果
*/
@RequestMapping("/addMenu")
public Map addMenu(){
//添加管理员角色权限
SysRoleMenuEntity sysRoleMenuEntity = new SysRoleMenuEntity();
sysRoleMenuEntity.setMenuId(4L);
sysRoleMenuEntity.setRoleId(1L);
sysRoleMenuService.save(sysRoleMenuEntity);
//清除缓存
String username = "admin";
ShiroUtils.deleteCache(username,false);
Map map = new HashMap<>();
map.put("code",200);
map.put("msg","权限添加成功");
return map;
}
}
创建UserLoginController登录类
/**
* @Description 用户登录
* @Author Sans
* @CreateTime 2019/6/17 15:21
*/
@RestController
@RequestMapping("/userLogin")
public class UserLoginController {
@Autowired
private SysUserService sysUserService;
/**
* 登录
* @Author Sans
* @CreateTime 2019/6/20 9:21
*/
@RequestMapping("/login")
public Map login(@RequestBody SysUserEntity sysUserEntity){
Map map = new HashMap<>();
//进行身份验证
try{
//验证身份和登陆
Subject subject = SecurityUtils.getSubject();
UsernamePasswordToken token = new UsernamePasswordToken(sysUserEntity.getUsername(), sysUserEntity.getPassword());
//验证成功进行登录操作
subject.login(token);
}catch (IncorrectCredentialsException e) {
map.put("code",500);
map.put("msg","用户不存在或者密码错误");
return map;
} catch (LockedAccountException e) {
map.put("code",500);
map.put("msg","登录失败，该用户已被冻结");
return map;
} catch (AuthenticationException e) {
map.put("code",500);
map.put("msg","该用户不存在");
return map;
} catch (Exception e) {
map.put("code",500);
map.put("msg","未知异常");
return map;
}
map.put("code",0);
map.put("msg","登录成功");
map.put("token",ShiroUtils.getSession().getId().toString());
return map;
}
/**
* 未登录
* @Author Sans
* @CreateTime 2019/6/20 9:22
*/
@RequestMapping("/unauth")
public Map unauth(){
Map map = new HashMap<>();
map.put("code",500);
map.put("msg","未登录");
return map;
}
}
五.POSTMAN测试
登录成功后会返回TOKEN,因为是单点登录,再次登陆的话会返回新的TOKEN,之前Redis的TOKEN就会失效了
当第一次访问接口后我们可以看到缓存中已经有权限数据了,在次访问接口的时候,Shiro会直接去缓存中拿取权限,注意访问接口时候要设置请求头.
ADMIN这个号现在没有sys:info:all这个权限的,所以无法访问getInfoAll接口,我们要动态分配权限后,要清掉缓存,在访问接口时候,Shiro会去重新执行授权方法,之后再次把权限和角色数据放入缓存中
访问添加权限测试接口,因为是测试,我把增加权限的用户ADMIN写死在里面了,权限添加后,调用工具类清掉缓存,我们可以发现,Redis中已经没有缓存了
再次访问getInfoAll接口,因为缓存中没有数据,Shiro会重新授权查询权限,拦截通过
