9.shiro安全框架-quickstart

1.导入依赖

<dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-core</artifactId>
        <version>1.7.1</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.26</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.30</version>
    </dependency>
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>

2.配置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.配置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

        }


        log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");

        //测试用户的角色
        if (currentUser.hasRole("schwartz")) {
            log.info("May the Schwartz be with you!");
        } else {
            log.info("Hello, mere mortal.");
        }

        //检测权限

            log.info("You may use a lightsaber ring.  Use it wisely.");
        } else {
            log.info("Sorry, lightsaber rings are for schwartz masters only.");
        }

        //是否有更高的权限
        if (currentUser.isPermitted("winnebago:drive:eagle5")) {
            log.info("You are permitted to ‘drive‘ the winnebago with license plate (id) ‘eagle5‘.  " +
