Spring Security XML示例
在本教程中,我们将使用Spring MVC 框架实现 Spring Security。所有示例都是Spring MVC,并且是使用Maven项目创建的。
我们使用的是 Spring Security 5.0.0.RELEASE 版本,以下是maven依赖项,我们在所有示例中都使用了。(web core config)
<dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>5.0.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-core</artifactId> <version>5.0.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>5.0.0.RELEASE</version> </dependency>
要在Spring应用程序中实现Spring Security,我们可以使用XML或基于Java的配置对其进行配置。
我们来看一个示例,其中将使用XML来配置Spring Security。
最初,它是空的。因此,让我们创建一个Spring MVC应用程序并与Spring Security集成。
这是我们的项目布局。它包含一个控制器,三个XML文件和两个JSP文件。
Spring Security Project源代码
我们的项目名称为 springsecurity ,其中包含以下源文件。
控制器
HomeController。 Java
package com.nhooo.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller public class HomeController { @RequestMapping(value="/", method=RequestMethod.GET) public String home() { return "home"; } @RequestMapping(value="/admin", method=RequestMethod.GET) public String privateHome() { return "privatePage"; } }
Spring security配置
spring-security.xml
<beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd"> <http auto-config="true"> <intercept-url pattern="/admin" access="hasRole('ROLE_ADMIN')" /> </http> <authentication-manager> <authentication-provider> <user-service> <user name="admin" password="1234" authorities="hasRole(ROLE_ADMIN)" /> </user-service> </authentication-provider> </authentication-manager> </beans:beans>
Servlet调度程序

查看页面
home.jsp
<html> <head> <meta content="text/html; charset=UTF-8"> <title>Home</title> </head> <body> <h2>Welcome to Nhooo spring tutorial!</h2> </body> </html>
privatePage.jsp
home.jsp
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Admin</title> </head> <body> Hello Admin </body> </html>
输出
此示例使用Apache Tomcat v9.0执行。运行后,它会向浏览器产生以下输出。
最初,它将呈现 home.jsp 页面,其中显示以下输出。
如果我们在管理页面中输入/ admin ,则会在管理页面中添加spring security。浏览器,应用程序将产生以下输出。
请求URL: http: //localhost: 8080/springsecurity/admin
现在,这是Spring Security提供的保护资源的真正魔力。
此是spring security提供的模块,我们没有创建它。还会验证用户输入。
提供错误的凭据。
如果我们提供了错误的登录凭据,它将使用我们在 spring-security.xml 文件中提到的用户名和密码进行验证。
验证后,如果登录凭据不正确,则会引发错误消息。
在这个示例中,我们已经看到了Spring Security的登录模块,并且它如何验证与所提供的用户名和密码相对应。
接下来,我们将实现主题进一步的逻辑,例如: 成功登录后呈现用户。
