建立maven專案，配置pom如下：

		<dependency>
		   <groupId>org.apache.shiro</groupId>
		   <artifactId>shiro-core</artifactId>
		   <version>1.4.0</version>
		</dependency>
		<dependency>
		   <groupId>junit</groupId>
		   <artifactId>junit</artifactId>
		</dependency>
 

簡單驗證案例：

public class AuthenticationTest {
		private SimpleAccountRealm simpleAccountRealm=
		new SimpleAccountRealm();
    @Before
    public void addUser(){
        //simpleAccountRealm.addAccount("link","123456",);
        //新增角色、可同時新增多個角色
        simpleAccountRealm.addAccount("link","123456","admin");
    }
    @Test
    public void testAuthentication(){
        //1、構建SecurityManger環境
        DefaultSecurityManager defaultSecurityManager=
                      					new DefaultSecurityManager();
        defaultSecurityManager.setRealm(simpleAccountRealm);

        //2、主體提交認證請求
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject= SecurityUtils.getSubject();

        UsernamePasswordToken token=
        new UsernamePasswordToken("link","123456");
            subject.login(token);

            System.out.println("Authenticated:"+subject.isAuthenticated());
    		//角色驗證
   		 subject.checkRole("admin");
	//退出  
       subject.logout();
      System.out.println("Authenticated:"+subject.isAuthenticated());
	}
}
