下面内容是在看了涛哥的《跟我一起学shiro》 和 视频《一头扎入进shiro》 后整理出来备忘和方便自己和其它人学习。
个人主页：http://www.itit123.cn/ 很多其它干货等你来拿
第一步：创建maven版web项目：http://blog.csdn.net/qq_19558705/article/details/49887717
创建好后须要： 右击项目 ----> build path ----> config build path ----> add library ----> server runtime ----> 选择合适的就可以 避免出现 “The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path” 错误
第二步：导入相关的jar
<!-- 日志管理 --> <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> <!-- shiro --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.12</version> </dependency>
<!-- shiro 监听 --> <listener> <listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class> </listener> <!-- shiro 拦截 --> <filter> <filter-name>ShiroFilter</filter-name> <filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class> </filter> <filter-mapping> <filter-name>ShiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
第四步：身份验证
shiro.ini文件：
[main] #用户登入路径 authc.loginUrl=/login [users] ITDragon=123456,admin [urls] #该路径为匿名登入 /login=anon #身份验证后才干登入 /admin=authc
login.jsp：
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>登录页面</title> </head> <body> <form action="login" method="post"> userName:<input type="text" name="userName" /><br /> password:<input type="password" name="password" /><br /> <input type="submit" value="Submit" /> </form> </body> </html>
package com.shiro.servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
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;
@WebServlet("/login")
public class LoginServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
System.out.println("login doGet ... ");
request.getRequestDispatcher("login.jsp").forward(request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
System.out.println("login doPost ... ");
String userName = request.getParameter("userName");
String password = request.getParameter("password");
Subject subject = SecurityUtils.getSubject();
UsernamePasswordToken token = new UsernamePasswordToken(userName,password);
try {
subject.login(token);
response.sendRedirect("success.jsp");
} catch (Exception e) {
e.printStackTrace();
request.setAttribute("errorInfo", "username或者密码错误");
request.getRequestDispatcher("login.jsp").forward(request, response);
}
}
}
第五步：权限认证
shiro文件：
[main] #用户登入路径 authc.loginUrl=/login #角色验证 roles.unauthorizedUrl=/unauthorized.jsp #权限验证 perms.unauthorizedUrl=/unauthorized.jsp [users] ITDragon=123456,admin teacher1=123456,teacher student1=123456 [roles] admin=user:* teacher=student:* [urls] #该路径为匿名登入 /login=anon #身份验证后才干登入 /admin=authc #该路径验证是否拥有teacher角色 /student=roles[teacher] #该路径验证该角色是否拥有权限 /teacher=perms["admin:delete"]
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>错误页面</title>
</head>
<body>
对不起。您不具备该权限。
</body>
</html>在浏览器中訪问/teacher，推断用户是否拥有该权限。
由于没有准备相应的servlet，所以正确情况会显示404，若没有权限则会跳到 unauthorized.jsp 页面。
这样就完毕了web中shiro的HelloWorld，之后会具体记录笔记。
