Springboot-Shiro基本使用

Apache Shiro官网:https://shiro.apache.org/spring-boot.html.

一、依据官网快速搭建Quickstart

1.1 配置pom.xml依赖
 
            org.apache.shiro
            shiro-core
            1.7.1
        
        
        
            org.slf4j
            jcl-over-slf4j
            1.7.21
        
        
        
            org.slf4j
            slf4j-log4j12
            1.7.21
        
        
            log4j
            log4j
            1.2.17
        
1.2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
1.3 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

启动类

        SpringApplication.run(ShiroSpringbootApplication.class, args);
    }

}

测试
root用户

test用户

SecurityUtils. getSubject()

SecurityUtils. getSubject(),可以获得当前正在执行的Subject. 一个Subject就是一个应用程序的用户的安全。实际上称它为“User”,但太多的应用程序拥有已经拥有自己的 User 类/框架的现有 API,我们不想与它们发生冲突。此外,在安全领域,该术语Subject实际上是公认的术语。

getSubject()独立应用程序中的调用可能会Subject在特定于应用程序的位置返回基于用户数据的 ,并且在服务器环境(例如 Web 应用程序)中,它Subject根据与当前线程或传入请求关联的用户数据获取。

Session session = currentUser.getSession();
session.setAttribute( "someKey", "aValue" );

这Session是一个特定于 Shiro 的实例,它提供了您习惯于使用常规 HttpSessions 的大部分内容,但还有一些额外的好处和一个很大的区别:它不需要 HTTP 环境!
