新建基于maven的web项目工程，工程结构如下：

#### pom.xml导入需要的包 ####

<dependency>
    	<groupId>org.apache.shiro</groupId>
    	<artifactId>shiro-core</artifactId>
    	<version>1.3.2</version>
    </dependency>
    
    <dependency>
    	<groupId>org.apache.shiro</groupId>
    	<artifactId>shiro-web</artifactId>
    	<version>1.3.2</version>
    </dependency>
    
    
    <dependency>
    	<groupId>log4j</groupId>
    	<artifactId>log4j</artifactId>
    	<version>1.2.17</version>
    </dependency>
    <dependency>
    	<groupId>commons-logging</groupId>
    	<artifactId>commons-logging</artifactId>
    	<version>1.2</version>
    </dependency>
    <dependency>
    	<groupId>org.slf4j</groupId>
    	<artifactId>slf4j-api</artifactId>
    	<version>1.7.21</version>
    </dependency>
    <dependency>
    	<groupId>junit</groupId>
    	<artifactId>junit</artifactId>
    	<version>4.12</version>
    	<scope>test</scope>
    </dependency>
    
    <dependency>
    	<groupId>javax.servlet</groupId>
    	<artifactId>jstl</artifactId>
    	<version>1.2</version>
    </dependency>
    
    <dependency>
    	<groupId>taglibs</groupId>
    	<artifactId>standard</artifactId>
    	<version>1.1.2</version>
    </dependency>

#### Web.xml添加对Shiro的支持 ####

<listener>
    	<listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class>
    </listener>
    
    <filter>
    	<filter-name>ShiroFilter</filter-name>
    	<filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class>
    	<init-param>
    		<param-name>configPath</param-name>
    		<param-value>/WEB-INF/shiro.ini</param-value>
    	</init-param>
    </filter>
    
    <filter-mapping>
    	<filter-name>ShiroFilter</filter-name>
    	<url-pattern>/*</url-pattern>
    </filter-mapping>

web.xml中其他配置就是servlet的映射配置了，不同的servlet对应不同的请求url

<servlet>
    	<servlet-name>LoginServlet</servlet-name>
    	<servlet-class>com.itmyhome.LoginServlet</servlet-class>
    </servlet>
    <servlet-mapping>
    	<servlet-name>LoginServlet</servlet-name>
    	<url-pattern>/login</url-pattern>
    </servlet-mapping>
    
    <servlet>
    	<servlet-name>LogoutServlet</servlet-name>
    	<servlet-class>com.itmyhome.LogoutServlet</servlet-class>
    </servlet>
    <servlet-mapping>
    	<servlet-name>LogoutServlet</servlet-name>
    	<url-pattern>/logout</url-pattern>
    </servlet-mapping>

配置一个 ini 文件 例如 shiro.ini

[users]
    itmyhome=123456

##### login.jsp #####

<body>
    <form action="${pageContext.request.contextPath }/login" method="post">
    	username:
    	<input type="text" name="username" /> ${msgUsername }
    	<br>
    	password:
    	<input type="password" name="password" /> ${msgPassword }
    	<br>
    	<input type="submit" value="登陆">
    </form>
    </body>

##### success.jsp #####

<body>
          欢迎你${username }
        <a href="${pageContext.request.contextPath }/logout">退出</a>
     </body>

浏览器中输入http://localhost:8080/shiro5-web/login
