## **Shrio在普通工程下的使用流程** ##

**模拟测试的ini文件**

[users]
    dp:1234

**导入依赖**

<dependency>
          <groupId>org.apache.shiro</groupId>
          <artifactId>shiro-core</artifactId>
          <version>1.4.0</version>
        </dependency>
        
        <dependency>
          <groupId>commons-logging</groupId>
          <artifactId>commons-logging</artifactId>
          <version>1.2</version>
        </dependency>
        
        <dependency>
          <groupId>org.slf4j</groupId>
          <artifactId>slf4j-nop</artifactId>
          <version>1.7.25</version>
          <scope>test</scope>
        </dependency>

**1.构建securityManage工厂**

IniSecurityManagerFactory securityManagerFactory = new IniSecurityManagerFactory("classpath:shiro.ini");

**2.通过工厂创建 securityManage对象**

SecurityManager securityManager = securityManagerFactory.getInstance();

**3.将securityManage设置到运行环境中**

SecurityUtils.setSecurityManager(securityManager);

**4.创建一个主体（Subject）对象**

Subject subject = SecurityUtils.getSubject();

**5.创建token令牌**

UsernamePasswordToken token = new UsernamePasswordToken("dp", "1234");

**6.登陆**

try { 
                subject.login(token);
    
            }catch (UnknownAccountException e){ 
                System.out.println("账户不正确");
                e.printStackTrace();
            }catch (IncorrectCredentialsException e1){ 
                System.out.println("密码不正确");
                e1.printStackTrace();
            }

**7.退出**

subject.logout();

**运行截图**
