1. 创建一个maven工程。
2.选择好组织名和项目名，选择打包方式为war包，完成即可。
3.配置pom.xml文件，引入jar包。
<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.yrn</groupId> <artifactId>yrn-springSecurity-demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging>
<properties> <spring.version>4.2.4.RELEASE</spring.version> <servlet-api.version>2.5</servlet-api.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>4.1.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>4.1.0.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> </dependencies>
<build> <plugins> <!-- tomcat插件 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <!-- 前台启动端口：从8080开始 --> <port>8080</port> <!-- /表示把项目发布到tomcat的root路径下，访问时不需要再写项目路径 --> <path>/</path> </configuration> </plugin>
<!-- 不加这个，war工程可能会报错 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.6</version> <configuration> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin> </plugins> </build> </project>
4. 在webapp下加入WEBIN文件夹和web.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"> <!-- 解决post乱码 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
<servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 指定加载的配置文件 ，通过参数contextConfigLocation加载 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/*.xml</param-value> </init-param> </servlet>
<servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
<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>
</web-app>
5.在resources目录下创建两个文件夹
一个config用来存放application.properties，文件，这个文件是空的，但是得有，不知道在哪个地方加载了这个鬼文件，反正没有就报错了。
另外一个是用来放springmvc.xml和spring-security.xml的名为spring的文件夹。
5.1 其中springmvc.xml为如下的
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:mvc="http://www.springframework.org/schema/mvc" 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"> <context:property-placeholder location="classpath:config/application.properties" /> <!-- 放行所有静态资源 --> <mvc:default-servlet-handler/>
</beans>
5.2 pring-security.xml的文件内容如下
<?xml version="1.0" encoding="UTF-8"?> <bean:beans xmlns="http://www.springframework.org/schema/security" xmlns:bean="http://www.springframework.org/schema/beans" 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"> <http> <intercept-url pattern="/*" access="hasRole('ROLE_USER')" /> <form-login /> </http> <!-- 认证管理器 --> <authentication-manager> <authentication-provider> <user-service> <user authorities="ROLE_USER" name="admin" password="admin" /> </user-service> </authentication-provider> </authentication-manager> </bean:beans>
6.启动项目进行测试
右击项目，选择Debug As--> Maven Build进去启动
第一次启动需要进行启动配置，这里选择在pom.xml文件已经引入的tomcat插件。输入tomcat7:run，点击应用即可
启动完成后，在浏览器输入localhost:8080,可以进入默认的页面
这样简单的测试springsecurity的配置就完成了，下一节会进行一些其他的操作
