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。

Shiro架构和Hello  World的示例分析

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

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 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 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('编辑 ');                    actions.push('删除 ');                    actions.push('重置');                    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。
