SpringSecurity的配置

1、在pom.xml文件中导入依赖

<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>
			<plugin>
				<groupId>org.apache.tomcat.maven</groupId>
				<artifactId>tomcat7-maven-plugin</artifactId>
				<configuration>
					<!-- 指定端口 -->
					<port>8090</port>
					<!-- 请求路径 -->
					<path>/</path>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

2、在web.xml中配置过滤器

<?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>/*
	
	
		index.html
		index.htm
		index.jsp
		default.html
		default.htm
		default.jsp
	

3、在spring-security中配置信息

<?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" />
		<!-- 自定义登陆页面，login-page 自定义登陆页面 authentication-failure-url 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 登陆成功后跳转的页面。 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="/success.html" 
			/>
		<!-- 登出， invalidate-session 是否删除session logout-url：登出处理链接 logout-success-url：登出成功页面 
			注：登出操作 只需要链接到 logout即可登出当前用户 -->
		<security:logout invalidate-session="true" logout-url="/logout"
			logout-success-url="/login.jsp" />
		<!-- 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>

4、测试

我们在webapp下创建一个index.html页面，在页面中任意写些内容。
