SSM集成SpringSecurity（一）准备环境

前言

本系列文章主要是借助ssm环境整合springSecurity并学习，由于本系列文章是有关联性的，所以有可能的话请从第一章（本篇）开始阅读。最后一章会给出完整的项目代码。

简介

SpringSecurity是Spring的全家桶之一，功能十分强大，主要是提供web安全方面的保护，涉及到系统的认证，授权，防止跨站攻击等。

本系列文章会结合实例向大家说明如何使用SpringSecurity。

• 搭建SSM并集成Security
•  使用HttpBasic方式实现认证
•  使用FormLogin方法实现认证
•  自定义登录页面，自定义登录请求
•  user-service配置实现用户权限访问控制
•  自定义登录成功失败的处理
•  基于RBAC实现菜单权限
•  自定义UserDetailService类实现用户权限访问控制
•  密码
•  自定义过滤器实现验证码校验
•  rememberMe
•  使用标签优化权限细节。
•  获取登录的用户信息

搭建SSM并集成Security

1: 创建maven项目

2: 导入坐标依赖

3: 新增spring相关的配置文件

web.xml的配置

 

<?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"

version="2.5">

 

<!-- SpringSecurity过滤器链 -->

<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>

 

<!-- 启动Spring -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>

classpath:applicationContext.xml

classpath:spring-security.xml

</param-value>

</context-param>

 

<!--启动SpringMVC-->

<servlet>

<servlet-name>DispatcherServlet</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:springmvc.xml</param-value>

</init-param>

<!-- 服务器启动加载Servlet-->

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>DispatcherServlet</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

</web-app>

 

springmvc.xml的配置

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

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xmlns:contenxt="http://www.springframework.org/schema/context"

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/mvc

http://www.springframework.org/schema/mvc/spring-mvc.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context.xsd">

 

</beans>

 

applicationContext.xml的配置

 

 

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

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop.xsd">

</beans>

spring-security.xml的配置

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

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:security="http://www.springframework.org/schema/security"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-4.2.xsd

http://www.springframework.org/schema/security

http://www.springframework.org/schema/security/spring-security-4.2.xsd">

 

<security:http>

<security:http-basic/>

</security:http>

 

<security:authentication-manager>

</security:authentication-manager>

</beans>
 

 

4：启动项目，能成功访问项目，则配置完毕，可以使用springSecurity的。到目前为止，没有配置mybatis相关的东西，只是引入了依赖。后面使用的时候会把mybatis整合进来。
