新建基於maven的web項目工程，工程結構如下：
pom.xml導入需要的包
<!-- shiro核心包 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.3.2</version>
</dependency>
<!-- 添加shiro web支持 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.3.2</version>
</dependency>
<!-- 添加log4j日誌 -->
<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添加對Shiro的支持
<!-- 添加shiro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對應不同的請求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>
配置一個 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" /> ${msgPassword }
<br>
<input type="submit" value="登陸">
</form>
</body>
success.jsp
<body>
歡迎你${username }
<a href="${pageContext.request.contextPath }/logout">退出</a>
</body>
瀏覽器中輸入http://localhost:8080/shiro5-web/login
