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
