Shiro 一个Apache 权限处理框架,现在更流行于security,能够指定用户的具体操作哪一个按钮,搭配接口,通过注解实现。

官网:

http://shiro.apache.org/download.html

主要涉及

权限管理,权限认证,session管理,加密

支持web,缓存,并发,测试,记住我

Shiro架构

Subject 当前用户

Security 管理subject

Realm 相当于RealmDao

Hello World

找到官网下载zip包。解压后

找到samples/quickstart/QuickStart.java

并将resource下面的配置复制

QuickStart.java

注释已经写在代码内

public class Quickstart {


    private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);

    public static void main(String[] args) {

        // The easiest way to create a Shiro SecurityManager with configured
        // realms, users, roles and permissions is to use the simple INI config.
        // We'll do that by using a factory that can ingest a .ini file and
        // return a SecurityManager instance:

        // Use the shiro.ini file at the root of the classpath
        // (file: and url: prefixes load from files and urls respectively):
        Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
        SecurityManager securityManager = factory.getInstance();

        // for this simple example quickstart, make the SecurityManager
        // accessible as a JVM singleton.  Most applications wouldn't do this
        // and instead rely on their container configuration or web.xml for
        // webapps.  That is outside the scope of this simple quickstart, so
        // we'll just do the bare minimum so you can continue to get a feel
        // for things.
        SecurityUtils.setSecurityManager(securityManager);

        // Now that a simple Shiro environment is set up, let's see what you can do:

        // get the currently executing user:

        //获取当前的subject   SecurityUtils.getSubject()
        Subject currentUser = SecurityUtils.getSubject();

        // Do some stuff with a Session (no need for a web or EJB container!!!)
        //获取session
        Session session = currentUser.getSession();
        //放入属性
        session.setAttribute("someKey", "aValue");
        //验证是否取到

        String value = (String) session.getAttribute("someKey");
        if (value.equals("aValue")) {
            log.info("Retrieved the correct value! -*******[" + value + "]");
        }

        // let's login the current user so we can check against roles and permissions:
        //测试是否被认证
        if (!currentUser.isAuthenticated()) {
            //用户名密码封装
            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
            //记住我
            token.setRememberMe(true);
            try {
                //执行登录
                currentUser.login(token);
                //如果没有指定的用户
            } catch (UnknownAccountException uae) {
                log.info("There is no user with username of " + token.getPrincipal());
                //密码错误
            } catch (IncorrectCredentialsException ice) {
                log.info("Password for account " + token.getPrincipal() + " was incorrect!");
                //用户被锁定
            } catch (LockedAccountException lae) {
                log.info("The account for username " + token.getPrincipal() + " is locked.  " +
                        "Please contact your administrator to unlock it.");
            }
            // ... catch more exceptions here (maybe custom ones specific to your application?
            //总的认证异常处理
            catch (AuthenticationException ae) {
                //unexpected condition?  error?
            }
        }

        //say who they are:
        //print their identifying principal (in this case, a username):
        log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");

        //test a role:
        //测试是否有某一个角色
        if (currentUser.hasRole("schwartz")) {
            log.info("May the Schwartz be with you!");
        } else {
            log.info("Hello, mere mortal.");
        }

        //test a typed permission (not instance-level)
        //测试用户是否有一个行为  weild
        //isPermitted   The 'schwartz' role can do anything (*) with any lightsaber:
        if (currentUser.isPermitted("lightsaber:weild")) {
            log.info("You may use a lightsaber ring.  Use it wisely.");
        } else {
            log.info("Sorry, lightsaber rings are for schwartz masters only.");
        }

        //a (very powerful) Instance Level permission:
        //goodguy = winnebago:drive:eagle5   更具体的行为
        if (currentUser.isPermitted("winnebago:drive:eagle5")) {
            log.info("You are permitted to 'drive' the winnebago with license plate (id) 'eagle5'.  " +
                    "Here are the keys - have fun!");
        } else {
            log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");
        }

        //all done - log out!
        currentUser.logout();

        System.exit(0);
    }
}

实际应用

@RequiresPermissions("risk:thirdInterface:view")
  @GetMapping()
  public String thirdInterface(ModelMap map, ThirdInterface thirdInterface) {

    List<ThirdInterface> thirdInterfaceList = thirdInterfaceService.selectThirdInterfaceList(thirdInterface);
    map.put("list", thirdInterfaceList);

    return prefix + "/thirdInterface";
  }

配合前端

var editFlag = [[${@permission.hasPermi('system:user:edit')}]];
var removeFlag = [[${@permission.hasPermi('system:user:remove')}]];

formatter: function(value, row, index) {
                    var actions = [];
                    actions.push('<a class="btn btn-success btn-xs ' + editFlag + '" href="#" onclick="$.operate.edit(\'' + row.userId + '\')"><i class="fa fa-edit"></i>编辑</a> ');
                    actions.push('<a class="btn btn-danger btn-xs ' + removeFlag + '" href="#" onclick="$.operate.remove(\'' + row.userId + '\')"><i class="fa fa-remove"></i>删除</a> ');
                    actions.push('<a class="btn btn-info btn-xs ' + resetPwdFlag + '" href="#" onclick="resetPwd(\'' + row.userId + '\')"><i class="fa fa-key"></i>重置</a>');
                    return actions.join('');
                }

在角色的分配操作时指定是否拥有某个按钮的权限操作。
