一、Spring Security概述

Spring Security 的前身是 Acegi Security ，是 Spring 项目组中用来提供安全认证服务的框架。Spring Security 为基于J2EE企业应用软件提供了全面安全服务。
所需依赖

	</dependency>
	<dependency>
		<groupId>org.springframework.security</groupId>
		<artifactId>spring-security-config</artifactId>
		<version>5.0.1.RELEASE</version>

</dependencies>

二、快速入门默认页面

默认不使用自定义页面
在这里插入图片描述

1、pom.xml导入依赖

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

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          <path>/</path>
        </configuration>
      </plugin>
    </plugins>

2、web.xml中创建Filter

<?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">
  <display-name>SpringSecurity314</display-name>


  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:无自定义页面spring-security.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <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>


  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3、无自定义页面spring-security.xml

<?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">
    <security:http auto-config="true" use-expressions="false">
        <!-- intercept-url定义一个过滤规则
        pattern:表示对哪些url进行权限控制，
        access:属性表示在请求对应的URL时需要什么权限，
        默认配置时它应该是一个以逗号分隔的角色列表，请求的用户只需拥有其中的一个角色就能成功访问对应的URL -->
        <security:intercept-url pattern="/**" access="ROLE_USER" />
    </security:http>
    <security:authentication-manager>
        <security:authentication-provider>
            <security:user-service>
                <!--user授user权限-->
                <security:user name="song" password="{noop}song"
                               authorities="ROLE_USER" />
                <!--admin授admin权限-->
                <security:user name="admin" password="{noop}admin"
                               authorities="ROLE_ADMIN" />
            </security:user-service>
        </security:authentication-provider>
    </security:authentication-manager>
</beans>

4、index.jsp


<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h3>Hello Spring-security</h3>
</body>
</html>

三、快速入门自定义页面

1、spring-security.xml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">

    <!--自定义页面定向-->
    <!-- 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 -->
        <!-- intercept-url定义一个过滤规则
        pattern:表示对哪些url进行权限控制，
        access:属性表示在请求对应的URL时需要什么权限，
        默认配置时它应该是一个以逗号分隔的角色列表，请求的用户只需拥有其中的一个角色就能成功访问对应的URL -->
        <security:intercept-url pattern="/**" access="ROLE_USER" />
        <!-- 自定义登陆页面
            login-page:自定义登陆页面
            login-processing-url:登录的URL
            default-target-url 登陆成功后跳转的页面。

            authentication-failure-url:用户名密码不对
                用户权限校验失败之后才会跳转到这个页面，如果数据库中没有这个用户则不会跳转到这个页面。
            default-target-url="/success.html":默认目标路径
            authentication-success-forward-url:满足权限，认证成功进入的页面。
            注：登陆页面
                用户名固定 username      密码 password     action:login
         -->
        <security:form-login login-page="/login.html"
                             login-processing-url="/login"
                             username-parameter="username"
                             password-parameter="password"
                             authentication-failure-url="/failer.html"
                             default-target-url="/hello.html"
                             always-use-default-target="true"
                             authentication-success-forward-url="/success.html"/>
        <!-- 关闭CSRF,默认是开启的 -->
        <security:csrf disabled="true" />
    </security:http>

    <security:authentication-manager>
        <security:authentication-provider>
            <security:user-service>
                <!--授权-->
                <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>

2、web.xml中创建Filter

<?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">
  <display-name>SpringSecurity314</display-name>
  
  <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>
  <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>


  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3、HTML页面

login.html

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
</head>
<body>
<form action="login" method="post">
    <table>
        <tr>
            <td>用户名：</td>
            <td><input type="text" name="username"/></td>
        </tr>
        <tr>
            <td>密码：</td>
            <td><input type="password" name="password"/></td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="登录"/>
                <input type="reset" value="重置"/></td>
        </tr>
    </table>
</form>
</body>
</html>

failer.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h3>登陆失败</h3>
</body>
</html>

success.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h3>登陆成功</h3>
</body>
</html>
