前几天偶然学习了spring secutity 现在分享一下 这个安全框架的一些基础使用
首先先简单的看一下这个框架的介绍
其实这个框架主要就是 建立认证和授权让我们的权限操作变得更加安全
下面就是具体操作：
第一步：我们要导入相应的依赖：（注意这个是基于spring 所以要记得导入spring 的maven 的依赖）
<dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>5.0.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>5.0.1.RELEASE</version> </dependency>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.itheima.springSecurity314</groupId> <artifactId>SpringSecurity314</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <spring.version>5.0.2.RELEASE</spring.version> <spring.security.version>5.0.1.RELEASE</spring.security.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>${spring.security.version}</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>${spring.security.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <!-- java编译插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> </project>
第二步：我们要在我们的web.xml 里创建filter
<!-- 配置加载类路径的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring-security.xml</param-value> </context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 委派过滤器 --> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
第三步：是我们的最核心的配置， 我们要在 resources 里配置我们spring-security.xml文件， 也是securtiy 的核心配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:security="http://www.springframework.org/schema/security" 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"> <!-- 配置不过滤的资源（静态资源及登录相关） --> <security:http security="none" pattern="/login.html" /> <security:http security="none" pattern="/failer.html" /> <security:http auto-config="true" use-expressions="false" > <!-- 配置资料连接，表示任意路径都需要ROLE_USER权限 --> <security:intercept-url pattern="/**" access="ROLE_USER" /> <!-- 关闭CSRF,默认是开启的 --> <security:csrf disabled="true" /> </security:http> <security:authentication-manager> <security:authentication-provider> <security:user-service> <security:user name="user" password="{noop}user" authorities="ROLE_USER" /> <security:user name="admin" password="{noop}admin" authorities="ROLE_ADMIN" /> </security:user-service> </security:authentication-provider> </security:authentication-manager> </beans>
这里入门的 话我们就不进行数据库的交互了，然后 <security:user name="user" password="{noop}user" authorities="ROLE_USER" />通过这个配置简单的添加了两个假用户接下来要进行操作
咱们直接运行进入首页
security 会自动进入拦截，拦截我们运行页面的初始页面然后在我们没有设置 自定义也面时，他会进入security 给我们提供的登入页面
当我们输入正确的账户密码， 就会登入成功
当我们登入admin 的时候 及不符合我们规定的权限
我们会被提示 403 表示我们权限不足
ok 大概使用方法就是这样
