二、Shiro 认证开发

I、java开发

环境准备

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.9</version>
    </dependency>
    <dependency>
        <groupId>commons-logging</groupId>
        <artifactId>commons-logging</artifactId>
        <version>1.1.3</version>
    </dependency>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-core</artifactId>
        <version>1.2.2</version>
    </dependency>
</dependencies>

shiro配置文件： shiro.ini

[users]
zhang3=123123
li4=123456

测试

//测试认证
public class TestAuthor {
    /**
     * 认证
     * 安全管理器
     * 获取主题
     * token
     *
     */
    public static void main(String[] args) {
        //通过安全管理器工厂
        IniSecurityManagerFactory iniSecurityManagerFactory = new IniSecurityManagerFactory("classpath:shiro.ini");
        //获得安全管理器工厂
        SecurityManager securityManager = iniSecurityManagerFactory.getInstance();
        //将安全管理器交给安全工具类
        SecurityUtils.setSecurityManager(securityManager);

        //主体对象
        Subject subject = SecurityUtils.getSubject();
        //构建token
        UsernamePasswordToken token = new UsernamePasswordToken("zhang3", "123123");
        try {
            subject.login(token);
        } catch (AuthenticationException e) {
            e.printStackTrace();
        }
        //验证是否通过
        System.out.println(subject.isAuthenticated());
    }

}

异常

IncorrectCredentialsException:密码输入错误

UnknownAccountException:账户对比失败

DisabledAccountException:帐号被禁用

LockedAccountException:帐号被锁定

ExcessiveAttemptsException:登录失败次数过多

ExpiredCredentialsException:凭证过期

底层认证思路

public class MyRealm extends AuthenticatingRealm{
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    /**
    * 假装查询数据库
    *
    *
    */
		//获取用户名
        String principal = (String) authenticationToken.getPrincipal();
        if (principal.equals("zhang3")){
            SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo("zhang3", "123123", this.getName());
            return simpleAuthenticationInfo;

        }
        return null;
	}	

}
