shiro学习（一）

基础依赖：

shiro-core，junit（因为在单元测试中）

test.class

public class AuthenticationTest {
    SimpleAccountRealm realm = new SimpleAccountRealm();
    @Before
    public void addUser(){
        realm.addAccount("mark","123456");
    }
    @Test
    public void testAuthentication(){
        //1.构建securityManager环境
        DefaultSecurityManager securityManager = new DefaultSecurityManager();
        securityManager.setRealm(realm);
        //2.主体提交认证请求
        SecurityUtils.setSecurityManager(securityManager);
        Subject subject = SecurityUtils.getSubject();
        //获取主体之后，就提交认证
        UsernamePasswordToken token = new UsernamePasswordToken("mark","123456");
　　　　　//退出认证
        subject.login(token);
        System.out.println("是否认证成功isAuthenticated：" + subject.isAuthenticated());
　　　　　

//退出
subject.logout();
System.out.println("是否认证成功isAuthenticated：" + subject.isAuthenticated());

} }
//控制台
    是否认证成功isAuthenticated：true
//如果用户名不正确，报  
org.apache.shiro.authc.UnknownAccountException: Realm 

//如果密码不正确，报
org.apache.shiro.authc.IncorrectCredentialsException: Submitted credentials for token

授权检测         subject.checkRole("father");

SimpleAccountRealm realm = new SimpleAccountRealm();
    @Before
    public void addUser(){
        realm.addAccount("mark","123456","father");
    }
    @Test
    public void testAuthentication(){
        //1.构建securityManager环境
        DefaultSecurityManager securityManager = new DefaultSecurityManager();
        securityManager.setRealm(realm);
        //2.主体提交认证请求
        SecurityUtils.setSecurityManager(securityManager);
        Subject subject = SecurityUtils.getSubject();
        //获取主体之后，就提交认证
        UsernamePasswordToken token = new UsernamePasswordToken("mark","123456");
        subject.login(token);
        //打印认证是否成功
        System.out.println("是否认证成功isAuthenticated：" + subject.isAuthenticated());
        //授权
        subject.checkRole("father");
        //退出
        subject.logout();
        System.out.println("是否认证成功isAuthenticated：" + subject.isAuthenticated());

    }
}

如果授权角色改为mother   ，则报错             org.apache.shiro.authz.UnauthorizedException: Subject does not have role [mother]

自定义IniRealm

public class IniRealmTest {
    IniRealm iniRealm=new IniRealm("classpath:user.ini");
    @Test
    public void testIniRealm(){
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(iniRealm);
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken("admin", "admin");
        subject.login(token);
        System.out.println("自定义认证："+subject.isAuthenticated());
        //subject.logout();
        //验证权限名字
        subject.checkRole("admin");
        //验证，权限名是否拥有该权限
        subject.checkPermission("user:delete");
        //验证，权限名是否拥有多种相应权限
        subject.checkPermissions("user:delete","user:update");
    }
}

user.ini配置文件

其位置：

[users]
#用户名，密码，权限名字
admin=admin,admin
[roles]
#权限名=（拥有）删除用户的权限
admin=user:delete,user:update

JdbcRealm

首先要添加：mysql、druid依赖

代码：

public class JdbcRealmTest {
    /*
        JdbcRealm需要访问数据

     */
    DruidDataSource dataSource=new DruidDataSource();
    {
        dataSource.setUrl("jdbc:mysql://localhost:3306/shiro_test");
        dataSource.setUsername("root");
        dataSource.setPassword("");
    }
    @Test
    public void testJdbcRealm(){
        JdbcRealm jdbcRealm=new JdbcRealm();
        jdbcRealm.setDataSource(dataSource);
        //1.构建securityManager环境
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(jdbcRealm);

        SecurityUtils.setSecurityManager(defaultSecurityManager);
        //2.获取主体  进行认证
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken("admin","admin");
        subject.login(token);
        subject.isAuthenticated();
    }
}

数据库shiro-test,表users

SQL语句，在JdbcRealm.class默认写好

 深入，查询用户拥有的角色以及该角色拥有的权限

public class JdbcRealmTest {
    /*
        JdbcRealm需要访问数据

     */
    DruidDataSource dataSource=new DruidDataSource();
    {
        dataSource.setUrl("jdbc:mysql://localhost:3306/shiro_test?useUnicode=true&characterEncoding=utf-8&useSSL=false");
        dataSource.setUsername("root");
        dataSource.setPassword("");
    }
    @Test
    public void testJdbcRealm(){
        JdbcRealm jdbcRealm=new JdbcRealm();
        jdbcRealm.setDataSource(dataSource);
        //jdbc设置权限开关
        jdbcRealm.setPermissionsLookupEnabled(true);
        //1.构建securityManager环境
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(jdbcRealm);

        SecurityUtils.setSecurityManager(defaultSecurityManager);
        //2.获取主体  进行认证
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken("admin","admin");
        subject.login(token);
        subject.isAuthenticated();
        subject.checkRole("admin");
        subject.checkRoles("admin","user");
        subject.checkPermission("user:select");
    }
}

注意：查询的表需要sql语句的表一致，不然报错

注意查询权限数据需jdbcrealm需开启权限开关

代码：  jdbcRealm.setPermissionsLookupEnabled(true);

哈哈哈，如果表名不一致，当然也可以啊，那就要手写SQL语句（也不难，抄袭而已）

SQL语句：

　　　　　//认证
        String sql_pwd="select password from test_user where username= ?";
        jdbcRealm.setAuthenticationQuery(sql_pwd);
        //认证 角色
        String sql_role="select role_name from test_user_roles where username=?";
        jdbcRealm.setUserRolesQuery(sql_role);
        //认证  权限
        String sql_per="select permission from test_roles_permissions where role_name=?";
        jdbcRealm.setPermissionsQuery(sql_per);

测试类

public class JdbcRealmSQL {
    //连接数据库
    DruidDataSource dataSource=new DruidDataSource();
    {
        dataSource.setUrl("jdbc:mysql://localhost:3306/shiro_test?useUnicode=true&characterEncoding=utf-8&useSSL=false");
        dataSource.setUsername("root");
        dataSource.setPassword("");
    }
    @Test
    public void testSql(){
        //自定义JdbcRealm
        JdbcRealm jdbcRealm = new JdbcRealm();
        jdbcRealm.setDataSource(dataSource);
        //开启权限设置开关
        jdbcRealm.setPermissionsLookupEnabled(true);
        /*
            下面是自定义sql语句，查询的是以test_开头的表
         模板语句
         "select password from users where username = ?";
         "select password, password_salt from users where username = ?";
         "select role_name from user_roles where username = ?";
         "select permission from roles_permissions where role_name = ?";
         */
        //认证
        String sql_pwd="select password from test_user where username= ?";
        jdbcRealm.setAuthenticationQuery(sql_pwd);
        //认证 角色
        String sql_role="select role_name from test_user_roles where username=?";
        jdbcRealm.setUserRolesQuery(sql_role);
        //认证  权限
        String sql_per="select permission from test_roles_permissions where role_name=?";
        jdbcRealm.setPermissionsQuery(sql_per);

        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(jdbcRealm);
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken("xiaoming","123456");
        //认证  登录
        subject.login(token);
        //认证 角色
        subject.checkRole("admin");
        subject.checkRoles("admin","user");
        //认证  权限
        subject.checkPermission("user:delete");
    }
}
