在项目sample——>QuickStart即可找到源代码
1、首先导入maven依赖
<dependencies>
<dependency>
<groupId>org.apache.shirogroupId>
<artifactId>shiro-coreartifactId>
<version>1.5.2version>
dependency>
<dependency>
<groupId>org.slf4jgroupId>
<artifactId>jcl-over-slf4jartifactId>
<version>1.7.21version>
dependency>
<dependency>
<groupId>org.slf4jgroupId>
<artifactId>slf4j-log4j12artifactId>
<version>1.7.21version>
dependency>
<dependency>
<groupId>log4jgroupId>
<artifactId>log4jartifactId>
<version>1.2.17version>
dependency>
dependencies>
2、写一个log4j的配置文档
log4j.properties
log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n
# General Apache libraries
log4j.logger.org.apache=WARN
# Spring
log4j.logger.org.springframework=WARN
# Default Shiro logging
log4j.logger.org.apache.shiro=INFO
# Disable verbose logging
log4j.logger.org.apache.shiro.util.ThreadContext=WARN
log4j.logger.org.apache.shiro.cache.ehcache.EhCache=WARN
3、写一个shiro.ini的配置文件
第一次配置时创建不了*ini文件名的的文件,此时idea需要下载InI插件,然后配置就好了。
shiro.ini
[users]
# user 'root' with password 'secret' and the 'admin' role
root = secret, admin
# user 'guest' with the password 'guest' and the 'guest' role
guest = guest, guest
# user 'presidentskroob' with password '12345' ("That's the same combination on
# my luggage!!!" ;)), and role 'president'
presidentskroob = 12345, president
# user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'
darkhelmet = ludicrousspeed, darklord, schwartz
# user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
lonestarr = vespa, goodguy, schwartz
# -----------------------------------------------------------------------------
# Roles with assigned permissions
#
# Each line conforms to the format defined in the
# org.apache.shiro.realm.text.TextConfigurationRealm#setRoleDefinitions JavaDoc
# -----------------------------------------------------------------------------
[roles]
# 'admin' role has all permissions, indicated by the wildcard '*'
admin = *
# The 'schwartz' role can do anything (*) with any lightsaber:
schwartz = lightsaber:*
# The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with
# license plate 'eagle5' (instance specific id)
goodguy = winnebago:drive:eagle5
配置文件说明
配置文件中包含两个部分用户[users]和角色[roles]
.
用户配置的格式是: 用户名=密码,角色1,角色2,…角色n
如:root = secret, admin 用户名是 root,密码是secret,拥有角色admin
一个用户可以具有多个角色。注意逗号是英文的。
.
角色配置的格式是: 角色名=权限1,权限2…权限n
如: admin = * 表示admin角色拥有所有权限
role1=perm1,perm2,角色名是role1,拥有perm1和perm2两个权限。
4创建QuickStart类
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.realm.text.IniRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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();*/
DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
defaultSecurityManager.setRealm(iniRealm);
// 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(defaultSecurityManager);
// Now that a simple Shiro environment is set up, let's see what you can do:
// get the currently executing user:
Subject currentUser = SecurityUtils.getSubject();
// Do some stuff with a Session (no need for a web or EJB container!!!)
Session session = currentUser.getSession();
session.setAttribute("someKey", "aValue");
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:
if (!currentUser.isAuthenticated()) {
UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
token.setRememberMe(true);
try {
currentUser.login(token);
} catch (UnknownAccountException uae) {
log.info("There is no user with username of " + token.getPrincipal());
} catch (IncorrectCredentialsException ice) {
log.info("Password for account " + token.getPrincipal() + " was incorrect!");
} 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?
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:
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)
if (currentUser.isPermitted("lightsaber:wield")) {
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:
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);
}
}
踩坑:官方项目里给的介绍是使用IniSecurityManagerFactory,该类上面划横线现在已经过时,不推荐使用,如果这里在创建QucikStart时出现报错等情况,可以采用DefaultSecurityManager类来实现安全管理,本案例默认使用DefaultSecurityManager
//官方推荐默认代码
/*Factory factory = new IniSecurityManagerFactory("classpath:shiro.ini");
SecurityManager securityManager = factory.getInstance();*/
//报错结局方案
//初始化DefaultSecurityManager 实例
DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
//创建一个基于ini文件数据源
IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
//将数据绑定到defaultSecurityManager中
defaultSecurityManager.setRealm(iniRealm);
//把defaultSecurityManager实例绑定到securityManager
SecurityUtils.setSecurityManager(defaultSecurityManager);
