Java-Shiro（二）：HelloWord

新建项目&&配置pom.xml导入包

新建maven java project项目；

修改pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

        </dependency>
    </dependencies>
</project>

新建shiro.ini和log4j日志配置文件log4j.properties

在项目的src/main/java下新建shiro.ini和log4j.properties文件

shiro.ini和log4j.properties文件可以从

拷贝，shiro.ini文件内容为：

# -----------------------------------------------------------------------------
# Users and their assigned roles
# -----------------------------------------------------------------------------
[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
# -----------------------------------------------------------------------------
[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

修改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=INFO
 
# Spring
log4j.logger.org.springframework=INFO
 
# Default Shiro logging
log4j.logger.org.apache.shiro=INFO
 
# Disable verbose logging
log4j.logger.org.apache.shiro.util.ThreadContext=INFO
log4j.logger.org.apache.shiro.cache.ehcache.EhCache=INFO

新建com.dx.spring.shiro包，把

下Quickstart.java拷贝到com.dx.spring.shiro包下：

package com.dx.spring.shiro;
 
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.mgt.SecurityManager;
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<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);
 
        // 获取当前环境下的一个Subject操作对象
        // 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();
 
        // 将一个对象存储到shiro的Session对象中，并验证是否有操作权限。
        // 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:weild")) {
            log.info("You may use a lightsaber ring.  Use it wisely.");
        } else {
            log.info("Sorry, lightsaber rings are for schwartz masters only.");
        }
 
        // 验证当前认证用户是否拥有某个具体操作：商品管理：删除：商品ID为5的记录
        // 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);
    }
}

编译运行，打印信息如下：
