以下是大体思路

## 1、导入坐标 ##

<properties>
            <spring.version>4.2.4.RELEASE</spring.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-huaweibc</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>

## 2、web.xml ##

配置spring提供的代理过滤器。web.xml中配置spring框架的代理过滤器DelegatingFilterProxy

<context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:spring/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>

## 3、spring-security配置文件 ##

<?xml version="1.0" encoding="UTF-8"?>
    <beans:beans xmlns="http://www.springframework.org/schema/security"
        xmlns:beans="http://www.springframework.org/schema/beans"
        xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
        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://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
                            http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd">
       
        
        <http pattern="/*.html" security="none"></http>
        <http pattern="/css/**" security="none"></http>
        <http pattern="/img/**" security="none"></http>
        <http pattern="/js/**" security="none"></http>
        <http pattern="/plugins/**" security="none"></http>
    　　
        <http pattern="/seller/add.do" security="none"></http>
    
        
        <http use-expressions="false">
            
            <intercept-url pattern="/**" access="ROLE_USER"/>
            
            <form-login  login-page="/shoplogin.html" default-target-url="/admin/index.html" authentication-failure-url="/shoplogin.html" always-use-default-target="true"/>
            <csrf disabled="true"/>
            
            <headers>
                <frame-options policy="SAMEORIGIN"/>
            </headers>
    
            <logout/>
        </http>
        
        
        <authentication-manager>
            <authentication-provider user-service-ref="userDetailService"> 
       
                <password-encoder ref="bcryptEncoder"></password-encoder>
            </authentication-provider>    
        </authentication-manager>
            
        
        <beans:bean id="userDetailService" class="com.huawei.service.UserDetailsServiceImpl">
        
            <beans:property name="sellerService" ref="sellerService"></beans:property>
        </beans:bean>
        
        
        <dubbo:application name="huawei-shop-web" />
        <dubbo:registry address="zookeeper://127.0.0.1:2181"/>    
        <dubbo:reference id="sellerService" interface="com.huawei.sellergoods.service.SellerService"></dubbo:reference>
        
        
        <beans:bean id="bcryptEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"></beans:bean>
    </beans:beans>

## 4、UserDetailService的实现类（把这个类加载进spring容器中采用xml配置，不要使用注解，避免父子容器问题） ##

public class UserDetailsServiceImpl implements UserDetailsService {
        private SellerService sellerService;
        public void setSellerService(SellerService sellerService) {
            this.sellerService = sellerService;
        }
        @Override
        public UserDetails loadUserByUsername(String name) throws UsernameNotFoundException {
           //完成认证授权功能
            //根据name查询数据库或者seller对象，seller对象需要sellergoods_service进行查询
            TbSeller seller = sellerService.findOne(name); //name就是sellerId
            //不仅根据sellerid找到该商家，而且还需要审核后
            if(seller!=null && "1".equals(seller.getStatus())){
                //拼接角色列表
                List<GrantedAuthority> authorities = new ArrayList<>();
                authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
                //用户名  密码   角色列表
                return new User(name, seller.getPassword(), authorities);
            }
            return null;
        }
    }

## 5、测试 ##

直接运行测试，上方源码是搭建在分布式项目Dubbo+zookeeper运行的

## 6、拓展： ##

### 6.1、获取SpringSecurity中的用户信息 ###

String name =SecurityContextHolder.getContext().getAuthentication().getName();
