Servlet + Shiro

项目结构

两个Servlet类

LoginServlet 代码如下

package com.zhen.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;

public class LoginServlet extends HttpServlet{

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		// TODO Auto-generated method stub
		System.out.println("login doGet");
		req.getRequestDispatcher("login.jsp").forward(req, resp);
	}
	
	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

		System.out.println("login doPost");
		String userName = req.getParameter("userName");
		String password = req.getParameter("password");
		System.out.println("login:name="+userName+" password="+password);
		
		Subject currentUser = SecurityUtils.getSubject();
		UsernamePasswordToken token = new UsernamePasswordToken(userName, password);
		try {
			currentUser.login(token);
			resp.sendRedirect("success.jsp");
		} catch (Exception e) {
			e.printStackTrace();
			req.setAttribute("errorInfo", "用户名或者密码错误");
			req.getRequestDispatcher("login.jsp").forward(req, resp);
		}
		
	}
}

AdminServlet 代码如下

package com.zhen.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class AdminServlet extends HttpServlet{

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		System.out.println("admin doGet");
	}
	
	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		System.out.println("admin doPost");
	}
}

配置 web.xml 文件，如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
  
  <listener>
    <listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class>
  </listener>
  
  <!-- 添加 shiro 支持 -->
  <filter>
    <filter-name>ShiroFilter</filter-name>
    <filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class>
   <!--  <init-param>

    </init-param> -->
  </filter>
  
  <filter-mapping>
    <filter-name>ShiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <!-- <dispatcher>REQUEST</dispatcher>

  </filter-mapping>
  
  <servlet>
  	<servlet-name>LoginServlet</servlet-name>
  	<servlet-class>com.zhen.servlet.LoginServlet</servlet-class>
  </servlet>
  <servlet-mapping>
  	<servlet-name>LoginServlet</servlet-name>
  	<url-pattern>/login</url-pattern>
  </servlet-mapping>
  
  <servlet>
  	<servlet-name>adminServlet</servlet-name>
  	<servlet-class>com.zhen.servlet.AdminServlet</servlet-class>

  <servlet-mapping>
  	<servlet-name>adminServlet</servlet-name>
  	<url-pattern>/admin</url-pattern>
  </servlet-mapping>
  
  
</web-app>

WEB-INF 下创建 shiro.ini文件，如下

[main]
authc.loginUrl=/login
roles.unauthorizedUrl=/unauthorized.jsp
perms.unauthorizedUrl=/unauthorized.jsp
[users]
zhen=123,admin
jack=jack,teacher
marry=marry
json=json
[roles]
admin=user:*
teacher=student:*
[urls]
/login=anon
/admin=authc
/admin?=authc
/admin*=authc
/admin/**=authc
/student=roles[teacher]
/teacher=perms[user:create]

项目大概就这么些东西，主要来看下 shiro.ini 文件中每行代表的意思

[main]

authc.loginUrl=/login　　:身份验证的登录路径

roles.unauthorizedUrl=/unauthorized.jsp　　:角色认证不通过要跳转到的路径

perms.unauthorizedUrl=/unauthorized.jsp　　:权限认证不通过要跳转到的路径

[users]

zhen=123,admin　　 :zhen用户，密码为123，角色为admin

jack=jack,teacher :jack用户，密码为jack，角色为teacher

marry=marry　　　　:marry用户，密码为marry

[roles]

admin=user:*　　　　:admin角色拥有的权限为 user:*

teacher=student:*　:teacher角色拥有的权限为 student:*

[urls]

/login=anon　　: 表明 /login 此请求不需要进行身份认证

/admin=authc　　: 表明 /admin 请求需要进行身份认证，身份认证的登录路径对应上边的 authc.loginUrl

/admin?=authc　 : 表明 /admin? 请求需要进行身份认证，/admin? 可以匹配为 /admin1 /admin2,?匹配一个字符

/admin*=authc　 : 表明 /admin* 请求需要进行身份认证，/admin* 可以匹配为 /admin1,/admin12,/admin, * 匹配零个、一个或多个字符

/admin/**=authc :表明 /admin/** 请求需要进行身份认证，/admin/** 可以匹配为 /admin/a , /admin/a/b, **匹配零个或多个路径

/student=roles[teacher]　　: 表明 /student 请求只有角色为 teacher 的用户才能访问

/teacher=perms[user:create] : 表明／teacher 请求只有拥有 user:create 权限的用户才能访问

url 匹配符

？
匹配一个字符
*
匹配零个、一个或多个字符
**
匹配零个或多个路径
