shiro简单的认证功能

使用静态shiro.ini文件完成认证

创建项目到爆

　　　　　<dependency>

            <groupId>org.apache.shiro</groupId>

            <artifactId>shiro-core</artifactId>

            <version>1.4.1</version>

        </dependency>

        <!-- Shiro uses SLF4J for logging.  We'll use the 'simple' binding

             in this example app.  See http://www.slf4j.org for more info. -->

        <dependency>

            <groupId>org.slf4j</groupId>

            <artifactId>slf4j-simple</artifactId>

            <version>1.7.21</version>

            <scope>test</scope>

        </dependency>

        <dependency>

            <groupId>org.slf4j</groupId>

            <artifactId>jcl-over-slf4j</artifactId>

            <version>1.7.21</version>

            <scope>test</scope>

        </dependency>

核心的shiro和log4j依赖

顺便创建log4j文件

创建shiro.ini

import org.apache.shiro.util.Factory;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.apache.shiro.SecurityUtils;

import org.apache.shiro.authc.AuthenticationToken;

import org.apache.shiro.authc.UsernamePasswordToken;

import org.apache.shiro.config.IniSecurityManagerFactory;

import org.apache.shiro.mgt.SecurityManager;

import org.apache.shiro.subject.Subject;

public class TestAuthenticationApp {

    //日志输出工具

    private static final transient Logger log = LoggerFactory.getLogger(TestAuthenticationApp.class);

    public static void main(String[] args) {

         String username = "zhangsan";

         String password = "123456";

         log.info("My First Apache Shiro Application");

         //1 创建安全管理器的工厂对象

         Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");

         //2 使用工厂创建安全管理器

         SecurityManager securityManager = factory.getInstance();

         //3 把当前的安全管理器绑定到线程

         SecurityUtils.setSecurityManager(securityManager);

         //4 使用SecurityUtils.getSubject() 得到主体

         Subject currentUser = SecurityUtils.getSubject();

        //5 封装用户名

         AuthenticationToken arg0 = new UsernamePasswordToken(username, password);

         currentUser.login(arg0);

         System.out.println("认证通过");

    }

}

当用户名或者密码不正确时，会抛出相应的异常

使用cry cateh 抛出相应的中文提示即可
