今天就跟大家聊聊有关Shiro架构和Hello World的示例分析,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。
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。
