2、配置shiro拦截器机制
/**

**/
@Slf4j
public class MyShiroRealm extends AuthorizingRealm {
@Lazy
@Autowired
private ITSysUserInfoService itSysUserInfoService;
@Lazy
@Autowired

@Lazy
@Autowired
private TSysPermissionServiceCache tSysPermissionServiceCache;
/**

**/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// 权限信息对象info,用来存放查出的用户的所有的角色（sysRole）及权限（permission）
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
TSysUserInfo user = ShiroUtils.getUserInfo();
Set permissionName = new HashSet<>();
//通过用户id获取用户的角色
List sysRoles = tSysRoleService.getAllByUserId(user.getId());
//定义角色名称集合
Set roleName = new HashSet<>();
if (sysRoles != null && !sysRoles.isEmpty()) {
sysRoles.stream().forEach(sysRole -> {
//根据角色id获取该角色的所有权限
List permissions = tSysPermissionServiceCache.getCacheAndSet(sysRole.getId());
if (permissions != null && !permissions.isEmpty()) {
permissionName.addAll(permissions);
}
roleName.add(sysRole.getRoleName());
});
}
log.info("{}执行授权，获取到的权限为{}", user.getMobile(), JSON.toJSONString(permissionName));
//添加进shiro的权限
authorizationInfo.addStringPermissions(permissionName);
//添加进shiro的角色
authorizationInfo.setRoles(roleName);
// 用户的角色集合
return authorizationInfo;
}/**

@Override

throws AuthenticationException {
//获取用户的输入的账号.
String username = (String) token.getPrincipal();
//通过username从数据库中查找 User对象
// 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
TSysUserInfo userInfo = itSysUserInfoService.findByUsername(username);
if (userInfo == null) {
return null;
}
if ("0".equals(userInfo.getStatus())) { //账户冻结
throw new LockedAccountException();

String credentials = userInfo.getPassword();
ByteSource credentialsSalt = ByteSource.Util.bytes(username);
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
//用户信息可以存用户name 但你通过SecurityUtils.getSubject().getPrincipal()获取到的就是name
// 如果这里你存入用户对象那你SecurityUtils.getSubject().getPrincipal()获取到的就是用户对象 如果是存入对象可能会造成获取用户信息脏读的问题。
userInfo,
credentials, //密码
credentialsSalt,//密码盐
//我设置getName()缓存中存的会一直是同一个key，
//这样会导致后面一个登陆的人会把前面一个登陆的人授权的权限给覆盖掉 而用用户的唯一标识就不会出现这个问题
userInfo.getMobile()//realm name
);
return authenticationInfo;
}
}
对于到底是用户对象还是用户名称作为Shiro的缓存可以看看这篇文章

4、定义session管理器MySessionManager
