电商项目mall学习(4)整合SpringSecurity和JW

作者: xywh | 来源:发表于2020-06-23 07:02 被阅读0次

向电商项目中集成安全认证和授权功能

使用框架

1.SpringSecurity

SpringSecurity是一个认证和授权框架,对于Spring来说SpringSecurity是一套web安全标准

2.JWT

JWT是Json Web Token的缩写,基于RFC7519标准定义的一种可以安全传输的json对象,由于使用了数字签名,所以是安全和可以信任的

JWT的组成
- JWT token的格式为:

header.payload.signature

header中用于存放签名的生成算法

{"alg": "HS512"}

payload中用于存放用户名,token的生成时间,过期时间

{"sub":"admin","created":"1592831217914","exp":"1593436017"}

signature为以header和payload生成的签名,一旦header和payload被篡改,将验证失败

HMACSHA256(
base64UrlEncode(header) + "." +
base64UrlEncode(payload),secret)

JWT实例

可以在jwt.io网站上对jwt实例进行解析https://jwt.io/

JWT的认证和授权原理
1. 用户调用登录接口，登录成功后获取到JWT的token；
2. 之后用户每次调用接口都在http的header中添加一个叫Authorization的头，值为JWT的token；
3. 后台程序通过对Authorization头中信息的解码及数字签名校验来获取其中的用户信息，从而实现认证和授权。

3.Hutool

Hutool是一个丰富的Java开源工具包,它帮助我们简化每一行代码，减少每一个方法，mall项目采用了此工具包。

项目源码地址

https://github.com/macrozheng/mall-learning/tree/master/mall-tiny-04

项目使用表说明

ums_admin：后台用户表
ums_role：后台用户角色表
ums_permission：后台用户权限表
ums_admin_role_relation：后台用户和角色关系表，用户与角色是多对多关系
ums_role_permission_relation：后台用户角色和权限关系表，角色与权限是多对多关系
ums_admin_permission_relation：后台用户和权限关系表(除角色中定义的权限以外的加减权限)，加权限是指用户比角色多出的权限，减权限是指用户比角色少的权限
使用MyBatis Generator生成相关的model,mapper,mapper.xml
修改generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>

</generatorConfiguration>

执行Generator类,生成相关的数据表对应的类和配置

SpringBoot中添加SpringSecurity和JWT

1. 在项目中添加Security,Hutool和JWT的依赖,修改pom.xml文件,修改application.yml
pom.xml添加需要引入的SpringSecurity,JWT,Hutool依赖

<!--SpringSecurity依赖配置-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<!--Hutool Java工具包-->
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>4.5.7</version>
</dependency>
<!--JWT(Json Web Token)登录支持-->
<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt</artifactId>
    <version>0.9.0</version>
</dependency>

application.yml添加自定义jwt信息

# 自定义jwt key
jwt:
  tokenHeader: Authorization #JWT存储的请求头
  secret: mySecret #JWT加解密使用的密钥
  expiration: 604800 #JWT的超期限时间(60*60*24)
  tokenHead: Bearer  #JWT负载中拿到开头

1. 添加JWT token的工具类

相关方法说明
generateToken(UserDetails userDetails) :用于根据登录用户信息生成token
getUserNameFromToken(String token)：从token中获取登录用户的信息
validateToken(String token, UserDetails userDetails)：判断token是否还有效

4.相关联的需要定义的类包括JwtAuthenticationTokenFilter,RestAuthenticationEntryPoint,RestfulAccessDeniedHandler,AdminUserDetails,UmsAdminService
相关具体实现

JwtAuthenticationTokenFilter

在用户名和密码校验前添加的过滤器，如果请求中有jwt的token且有效，会取出token中的用户名，然后调用SpringSecurity的API进行登录操作。

    @Override

}

添加功能实现

添加UmsAdminService接口定义权限相关功能

package com.mall.mallmybatis.service;
import com.mall.mallmybatis.mbg.model.UmsAdmin;
import com.mall.mallmybatis.mbg.model.UmsPermission;

import java.util.List;


/**
 * 后台管理员Service
 * @author wangxing
 * @version 2020/6/22 15:51 Administrator
 */
public interface UmsAdminService {
    /**
     * 根据用户名获取后台管理员
     */
    UmsAdmin getAdminByUsername(String username);

    /**
     * 注册功能
     */
    UmsAdmin register(UmsAdmin umsAdminParam);

    /**
     * 登录功能
     * @param username 用户名
     * @param password 密码
     * @return 生成的JWT的token
     */
    String login(String username, String password);

    /**
     * 获取用户所有权限（包括角色权限和+-权限）
     */
    List<UmsPermission> getPermissionList(Long adminId);
}

实现UmsAdminService接口的实现类UmsAdminServiceImpl

@Service
public class UmsAdminServiceImpl implements UmsAdminService {
    private static final Logger LOGGER = LoggerFactory.getLogger(UmsAdminServiceImpl.class);

    /**

     * @return
     */
    @Override
    public UmsAdmin getAdminByUsername(String username) {
        UmsAdminExample example = new UmsAdminExample();
        example.createCriteria().andUsernameEqualTo(username);
        List<UmsAdmin> adminList = adminMapper.selectByExample(example);
        if (adminList != null && adminList.size() > 0) {
            return adminList.get(0);
        }

        umsAdmin.setCreateTime(new Date());
        umsAdmin.setStatus(1);
        //查询是否有相同用户名的用户
        UmsAdminExample example = new UmsAdminExample();
        example.createCriteria().andUsernameEqualTo(umsAdmin.getUsername());
        List<UmsAdmin> umsAdminList = adminMapper.selectByExample(example);

        return adminRoleRelationDao.getPermissionList(adminId);

}

3.调整Swagger的配置

通过修改配置实现调用接口自带Authorization头，这样就可以访问需要登录的接口了。

package com.mall.mallmybatis.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.ApiKey;
import springfox.documentation.service.AuthorizationScope;
import springfox.documentation.service.SecurityReference;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spi.service.contexts.SecurityContext;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

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

/**
 * 在线API配置类
 * @author wangxing
 * @version 2020/6/22 11:43 Administrator
 */
@Configuration
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为指定包路径下的类生成API文档
                .apis(RequestHandlerSelectors.basePackage("com.mall.mallmybatis.controller"))
                //为有@Api注解的Controller生成API文档
//                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                //为有@ApiOperation注解的方法生成API文档
//                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build()
                //添加登录认证
//        设置请求头信息
                .securitySchemes(securitySchemes())
//        设置需要登录认证的路径
                .securityContexts(securityContexts());
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("SwaggerUI")
                .description("mall learning")
                .contact("macro")
                .version("1.0")
                .build();
    }
    private List<ApiKey> securitySchemes() {
        //设置请求头信息
        List<ApiKey> result = new ArrayList<>();
        ApiKey apiKey = new ApiKey("Authorization", "Authorization", "header");
        result.add(apiKey);
        return result;
    }

    private List<SecurityContext> securityContexts() {
        //设置需要登录认证的路径
        List<SecurityContext> result = new ArrayList<>();
        result.add(getContextByPath("/brand/.*"));
        return result;
    }

    private SecurityContext getContextByPath(String pathRegex){
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(PathSelectors.regex(pathRegex))
                .build();
    }

    private List<SecurityReference> defaultAuth() {
        List<SecurityReference> result = new ArrayList<>();
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        result.add(new SecurityReference("Authorization", authorizationScopes));
        return result;
    }
}

4.给PmsBrandController接口中方法授权

给查询接口添加pms:brand:read权限

给修改接口添加pms:brand:update权限

给删除接口添加pms:brand:delete权限

给添加接口添加pms:brand:create权限
修改后PmsBrandController

package com.mall.mallmybatis.controller;
