Shiro集成web配置

                        

                    

                               

                        

    pom.xml文件配置如下

</project>

接下来修改maven项目 修改如下修改web.xml文件和添加META-INF文件

我们可以创建一个普通点的web项目从里面copyweb.xml和META-INF文件,但是需要注意的是俩个版本必须相同,

比如你创建的普通web项目                                                                             这是项目的目录

  

        把maven的index.jsp页面删掉重新创建一个index.jsp重新运行如图说明环境已经搭好

接下来开始web集成

                        

web.xml文件配置如下

<?xml version="1.0" encoding="UTF-8"?>

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

shiro.ini 配置如下

[main]
authc.loginUrl=/login
roles.unauthorizedUrl=/error.jsp
perms.unauthorizedUrl=/error.jsp
[users]
zs=123,admin
jack=123,teacher
json=345
[roles]
admin=user:*
teacher=student:*
[urls]
/login=anon
/admin=authc
/student=roles[teacher]

error.jsp

</head>
<body>
登录成功 ^_^
</body>
</html>

创建servlet 如下

                    

AdminServlet.java配置如下

package com.hp.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;

/**
 * Servlet implementation class AdminServlet
 */
@WebServlet("/AdminServlet")
public class AdminServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		System.out.println("adminservlet doget 已经执行");
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		System.out.println("adminservlet dopost 已经执行");
	}

}

LoginServlet.java配置 如下

package com.hp.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;

/**
 * Servlet implementation class LoginServlet
 */
@WebServlet("/LoginServlet")
public class LoginServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;


	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	System.out.println("login do get 方法已经执行");
	request.getRequestDispatcher("login.jsp").forward(request, response);
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String UserName = request.getParameter("userName");
		String password = request.getParameter("password");
		//获取实例化对象
		Subject subject = SecurityUtils.getSubject();
		UsernamePasswordToken token = new UsernamePasswordToken(UserName, password);
		try {
			subject.login(token);
			//跳转路径
			response.sendRedirect("success.jsp");
		} catch (Exception e) {
			e.printStackTrace();
			//跳转登录失败页面
			request.setAttribute("msg", "用户名或者密码不正确");
			request.getRequestDispatcher("login.jsp").forward(request, response);
		}
		

	}

}

接下来可以判断用户的身份认证

接下来判断用户的角色认证

                

我们先用zs 进行登录  

使用jack进行角色验证 

接下来判断用户的权限认证

首先使用jack进行验证 我们发现jack没有user:create这个权限

我们使用zs来进行验证 

url的配置方式

?配置一个字符 /user?  可以匹配/user1或者/user3 但是不能配置 /user 或者1/user12

使用如下

                    

接下来 访问user

访问user5

访问user123

       *是匹配零个或者一个或者多个字符 例如/admin* 可以匹配/admin1  /admin5  /admin121 但是不能匹配/admin/21 不能匹配多路径

访问text  如下

访问text121

访问text/12 这样就访问不到了

        **匹配零个或者多个路径 /admin/**  可以匹配/admin  或者/admin/12/12 但是不能匹配/admin21

配置如下

访问/demo

再次访问/demo/12/12

访问/demo21  就不能被访问
