一、Spring Security快速入门

1、建立一个新的webapp项目

2、在pom.xml中导入依赖

<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>8080</port> <!-- 请求路径 --> <path>/</path> </configuration> </plugin> </plugins> </build> </project>

3、配置web.xml

springSecurityFilterChain名字不能任意改变需要一个spring-security.xml文件 <?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>

spring-security.xml文件

在main/resources文件下新创建 spring-security.xml文件 <?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，ccess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"/> <!-- auto-config配置后，不需要在配置下面信息 <security:form-login /> 定义登录表单信息 <security:http-basic /> <security:logout /> --> </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、tomcat启动

pom.xml中已经嵌入了tomcat，所以可以简单的快速启动。①在终端Terminal中输入：mvn tomcat7:run

②网页中输入：http://localhost:8080/自动跳转页面：http://localhost:8080/login ③用户和密码输入：user自动跳跳转默认页面或者请求页面：http://localhost:8080/

二、使用自定义登录页面

新建自定义的登录页面

login.htmlfailer.htmsuccess.html

配置文件根据业务的实际需求更改具体位置

更改spring-security.xml文件配置

<?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" /> <!-- 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" authentication-failure-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> <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>

三、退出登录

在spring-security.xml配置中添加配置指定退出请求的路径/logout.do指定退出成功后返回的页面/login.jsp <!-- 退出 --> <security:logout invalidate-session="true" logout-url="/logout.do" logout-success-url="/login.jsp" /> 在（自定义页面）退出/注销的按钮上添加路径：绝对路径+/logout.do

然后在自定义页面中点击注销按钮，就完成退出操作返回登录页面

四、运行过程中的报错

1.sql语句不要写错，不要多空格 2.配置完成时还不能登录成功时，需要把下面的配置注释掉

通俗说就是在数据库中直接添加的数据是未加密的 <!-- 配置加密的方式 --> <!-- <security:password-encoder ref="passwordEncoder"/>-->
