<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="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 pattern="/login.html" security="none">http>
    <http pattern="/login_error.html" security="none">http>


    
    <http use-expressions="false">
        <intercept-url pattern="/*" access="ROLE_USER" />
        <form-login login-page="/login.html" default-target-url="/index.html" authentication-failure-url="/login_error.html"/>  
        <csrf disabled="true"/>
    http>


    
    <authentication-manager>
        <authentication-provider>
            <user-service>
                <user name="admin" password="123456" authorities="ROLE_USER"/>
            user-service>     
        authentication-provider>  
    authentication-manager>
beans:beans>


配置说明：
intercept-url 表示拦截页面   
/*  表示的是该目录下的资源，只包括本级目录不包括下级目录
/** 表示的是该目录以及该目录下所有级别子目录的资源
form-login  为开启表单登陆
use-expressions 为是否使用使用 Spring 表达式语言（ SpEL ），默认为true ,如果开启，则拦截的配置应该写成以下形式
login-page：指定登录页面。
authentication-failure-url：指定了身份验证失败时跳转到的页面。
default-target-url：指定了成功进行身份验证和授权后默认呈现给用户的页面。
csrf disabled="true"  关闭csrf ,如果不加会出现错误

<intercept-url pattern="/**" access="hasRole('ROLE_USER')" />

2. 运营商系统登录与安全控制(pingyougou_manage_web)

• 需求分析

  • 使用spring security框架实现指定用户登录和页面访问控制

• 配置文件的摘录

  • pom.xml的依赖添加

  
  <dependency>
      <groupId>org.springframework.securitygroupId>
      <artifactId>spring-security-webartifactId>        
  dependency>
  <dependency>
      <groupId>org.springframework.securitygroupId>
      <artifactId>spring-security-configartifactId>     
  dependency>
  

  • 在 web.xml 中添加配置文件的加载(基于监听器实现)和spring_security的配置(基于过滤器)

  <context-param>
      <param-name>contextConfigLocationparam-name>
      <param-value>classpath:spring/spring-security.xmlparam-value>
   context-param>
   <listener>
      <listener-class>
          org.springframework.web.context.ContextLoaderListener
      listener-class>
   listener>    
   <filter>  
      <filter-name>springSecurityFilterChainfilter-name>        <filter-class>org.springframework.web.filter.DelegatingFilterProxyfilter-class>  
   filter>  
   <filter-mapping>  
      <filter-name>springSecurityFilterChainfilter-name>  
      <url-pattern>/*url-pattern>  
   filter-mapping>  
  

  • 在 spring_security.xml 中添加配置

  
  <beans:beans xmlns="http://www.springframework.org/schema/security"
             xmlns:beans="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 pattern="/login.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 use-expressions="false">
  <intercept-url pattern="/*" access="ROLE_ADMIN" />
  <form-login login-page="/login.html"  default-target-url="/admin/index.html" authentication-failure-url="/login.html" always-use-default-target="true"/>
  <csrf disabled="true"/>
  <headers>
    <frame-options policy="SAMEORIGIN"/>
  headers>
    <logout  logout-success-url="/login.html"/>
  http>
  
  
        
  <authentication-manager>
  <authentication-provider>
    <user-service>
        <user name="admin" password="123" authorities="ROLE_ADMIN"/>
        <user name="sunwukong" password="dasheng" authorities="ROLE_ADMIN"/>
    user-service>
  authentication-provider>
  authentication-manager>
  
  beans:beans>

• 登录页面的修改

  • id="loginform" action="/login" method="post"

• 显示登录人

  • 注意是从spring_security中获取的username

  @RestController
  @RequestMapping("/login")
  public class LoginController {
    @RequestMapping("name")
    public Map name(){
        String name=SecurityContextHolder.getContext()
                .getAuthentication().getName();
        Map map=new HashMap();
        map.put("loginName", name);
        return map ;
    }
  }

• 退出登录

  • 使用spring_security默认的logout来退出

3. 商家申请入驻

• 需求分析

  • 商家填写相关表单,等待运营商进行审核, 需要将 状态设置成未审核

• 代码实现, 提交表单, 进行数据库保存 添加创建时间

4. 商家审核

• 需求分析
  
  • 在运营商管理界面显示 未审核 的商家, 点击详情页面, 进行数据回显, 点击审核 修改状态

5.商家系统登录与安全控制(pinyougou_shop_web)

• 因为有很多商家, 所以要在数据库进行, 校验, 所以需要 自定义认证类

package com.pinyougou.service;

import com.pinyougou.pojo.TbSeller;
import com.pinyougou.sellergoods.service.SellerService;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;

import java.util.ArrayList;
import java.util.List;

/**
 * 认证类
 */
public class UserDetailsServiceImpl implements UserDetailsService {

    private SellerService sellerService;

    public void setSellerService(SellerService sellerService) {
        this.sellerService = sellerService;
    }


    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        System.out.println("经过了UserDetailsServiceImpl");
        //构建角色列表
        List grantAuths = new ArrayList();
        grantAuths.add(new SimpleGrantedAuthority("ROLE_SELLER"));
        //得到商家对象
        TbSeller seller = sellerService.findOne(username);
        if (seller != null) {
            if (seller.getStatus().equals("1")) {
                return new User(username, seller.getPassword(), grantAuths);
            } else {
                return null;
            }
        } else {
            return null;

        }
    }
}

• 密码加密

@RequestMapping("/add")
    public Result add(@RequestBody TbSeller seller){
        //密码加密
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        String password = passwordEncoder.encode(seller.getPassword());
        seller.setPassword(password);
        try {
            sellerService.add(seller);
            return new Result(true, "增加成功");
        } catch (Exception e) {
            e.printStackTrace();
            return new Result(false, "增加失败");
        }
    }
