分布式项目中SpringSecurity使用数据库中的密码登陆

一、导入依赖

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-cas</artifactId>
        </dependency>

 

二、配置文件

在web-shop项目下的resources目录下创建spring-security.xml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:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"

    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">
  <!-- 放行的资源-->
    <http pattern="/*.html" security="none"/>
    <http pattern="/css/**" security="none"/>
    <http pattern="/img/**" security="none"/>
    <http pattern="/js/**" security="none"/>
    <http pattern="/plugins/**" security="none"/>
    <http pattern="/seller/add.do" security="none"/>

    <!-- use-expressions:设置是否启动SpEL表达式,默认值是true。 -->
    <http use-expressions="false">
        <!--
            配置SpringSecurity的拦截路径(拦截规则)
            * pattern:配置拦截规则。   /* 代表的是根路径下的所有资源(不包含子路径) /**代表的是根路径下所有的资源(包含子路径)
            * access:设置角色  角色命名 ROLE_角色名称  如:  ROLE_USER
        -->
        <intercept-url pattern="/**" access="ROLE_SELLER"/>

        <!--
        开启表单验证
            username-parameter="username"
            password-parameter="password"
            login-page            :登录页面名称  以  / 开始
            default-target-url    :登录成功后跳转的页面
            login-processing-url:提交的路径的设置 默认值"/login" 可以修改
        -->
        <form-login login-page="/shoplogin.html" default-target-url="/admin/index.html" always-use-default-target="true" authentication-failure-url="/shoplogin.html"/>

        <!-- 不使用csrf的校验,系统可以使用跨域请求 -->
        <csrf disabled="true"/>

        <!-- 配置框架页面不拦截 -->
        <headers>
            <frame-options policy="SAMEORIGIN"/>
        </headers>

        <!-- 注销的配置 -->
        <logout logout-url="/logout" logout-success-url="/shoplogin.html" />
    </http>

    <!-- 认证管理器 -->
    <authentication-manager>
        <authentication-provider user-service-ref="userDetailService">
        </authentication-provider>
    </authentication-manager>


    <!-- 引用dubbo 服务 -->
    <dubbo:application name="pinyougou-shop-web" />
    <dubbo:registry address="zookeeper://192.168.200.128:2181"/>

<!--注入服务提供者中的SellerService-->
<dubbo:reference id="sellerService" interface="cn.lqc.core.service.SellerService" > </dubbo:reference> <!-- 配置自定义的认证类 --> <beans:bean id="userDetailService" class="cn.lqc.core.service.UserDetailServiceImpl">
    <!--创建SellerService对象-->
<beans:property name="sellerService" ref="sellerService"></beans:property> </beans:bean> </beans:beans>

注意:dubbo应用名称必须和SpringMVC.Xml配置的应用名称一致。

 

三、创建自定义类(在当前web-shop项目下创建)

(1)在youlexuan-shop-web创建com.offcn.service包,包下创建类UserDetailsServiceImpl.java 实现SpringSecurity的UserDetailsService接口,重写loadUserByUsername方法

package cn.lqc.core.service;
import cn.lqc.core.pojo.seller.Seller;
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;

public class UserDetailServiceImpl implements UserDetailsService {

  
    private SellerService sellerService;
  //由于在配置文件中已经存在sellerService对象,这里提供setter方法,注入到自定义类中来,获取服务提供者中的service
    public void setSellerService(SellerService sellerService){
        this.sellerService = sellerService;
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        //构建角色列表
        List<GrantedAuthority> grantAuths=new ArrayList<GrantedAuthority>();
        grantAuths.add(new SimpleGrantedAuthority("ROLE_SELLER"));
        //得到商家对象,这里的username就是商家表主键sellerId
        Seller seller = sellerService.findOne(username);
        //商家必须是审核通过的
        if(seller != null && "1".equals(seller.getStatus())){
            return new User(username,seller.getPassword(),grantAuths);
        }
        return null;


    }
}

 

四、前端登录页面

表单提交的actio属性中为:/login

<div id="profile" class="tab-pane  active">
                            <form class="sui-form" id="loginForm" action="/login" method="post">
                                <div class="input-prepend"><span class="add-on loginname"></span>
                                    <input id="prependedInput" name="username" type="text" placeholder="邮箱/用户名/手机号" class="span2 input-xfat">
                                </div>
                                <div class="input-prepend"><span class="add-on loginpwd"></span>
                                    <input id="prependedInput" name="password" type="password" placeholder="请输入密码" class="span2 input-xfat">
                                </div>
                                <div class="setting">
                                    <label class="checkbox inline"><input name="m1" type="checkbox" value="2" checked="">自动登录</label>
                                    <span class="forget">忘记密码?</span>
                                </div>
                                <div class="logined">
                                    <a class="sui-btn btn-block btn-xlarge btn-danger" onclick="document.getElementById('loginForm').submit()" target="_blank">&nbsp;&nbsp;</a>
                                </div>
                            </form>

 

 

五、在web-shop下创建一个自定义类来获取当前登陆用户

//从安全框架中获取正在登陆的用户名
        String userName = SecurityContextHolder.getContext().getAuthentication().getName();
package cn.lqc.core.controller;

import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

@RestController
@RequestMapping("/login")
public class ShopLoginController {

    @RequestMapping("/showName")
    public Map<String,Object> showName(){
        Map<String,Object> map = new HashMap<>();
        //从安全框架中获取正在登陆的用户名
        String name = SecurityContextHolder.getContext().getAuthentication().getName();
        map.put("username",name);
        return map;
    }
 }
