Shiro学习笔记1 —— Hello World

1、创建一个Maven工程加载Shiro的jar包

        <!-- junit -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>
        <!-- Logging with SLF4J & LogBack -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>jcl-over-slf4j</artifactId>
            <version>1.7.13</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.13</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>jul-to-slf4j</artifactId>
            <version>1.7.13</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>1.1.3</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>1.1.3</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-access</artifactId>
            <version>1.1.3</version>
        </dependency>
        <!-- shiro -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.2.4</version>
        </dependency>
        <!-- apache commons -->
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>

2、日志文件：logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
        <resetJUL>true</resetJUL>
    </contextListener>
    <!-- To enable JMX Management -->
    <jmxConfigurator />

    <!-- 打印到控制台 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- encoder 默认配置为PatternLayoutEncoder -->
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{40} - %msg%n</Pattern>
        </layout>
    </appender>

    <!-- 打印日志到文件 -->
    <!-- 所有日志文件 -->
    <appender name="AllLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/shiro/all/%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{40} - %msg%n</pattern>
        </encoder>
    </appender>
    <!-- Task日志文件 -->
    <appender name="Tasklog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/shiro/task/%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{40} - %msg%n</pattern>
        </encoder>
    </appender>
    
    <!-- 为莫个包下的所有类指定Appender 这里也可以指定类名称例如：com.mcs.task.ClassName -->
    <!-- 
     <logger name="cn.mcs.task" level="DEBUG" >
         <appender-ref ref="Tasklog" />
     </logger>
      -->
     <logger name="org.springframework" level="INFO" /> 
       <logger name="org.springframework.beans" level="DEBUG" />

    <!-- 常用级别：ERROR 、WARN 、INFO 、DEBUG 、TRACE -->
    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
        <!-- <appender-ref ref="AllLog" /> -->
      </root>


</configuration>  

3、本地配置文件shiro.ini

[users]
admin=admin
zhang=123
wang=123

4、代码测试

public class TestShiro {
    
    private static Logger log = LoggerFactory.getLogger(TestShiro.class);  
    
    @Test
    public void testHelloworld() {    
        //1、获取SecurityManager工厂，此处使用Ini配置文件初始化SecurityManager
        Factory<org.apache.shiro.mgt.SecurityManager> factory =
                new IniSecurityManagerFactory("classpath:shiro.ini");
        //2、得到SecurityManager实例 并绑定给SecurityUtils
        org.apache.shiro.mgt.SecurityManager securityManager = factory.getInstance();
        SecurityUtils.setSecurityManager(securityManager);
        //3、得到Subject及创建用户名/密码身份验证Token（即用户身份/凭证）
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken("admin", "admin");
        
        try {
            //4、登录，即身份验证
            subject.login(token);
            log.info(token.getPrincipal().toString() + "用户登录验证成功！");
        } catch (AuthenticationException e) {
            //5、身份验证失败
        }

        Assert.assertEquals(true, subject.isAuthenticated()); //断言用户已经登录

        //6、退出
        subject.logout();
        log.info("用户已成功注销！");
    }

}
