mall-learning's Issues

JwtAuthenticationTokenFilter验证逻辑

你好，在 mall-tiny-04 节，JwtAuthenticationTokenFilter 类，有一处代码感到疑惑：

if (jwtTokenUtil.validateToken(authToken, userDetails)) ，其中，
authToken 和 userDetails 源头是一致的，都是来自 Authorization，那这个比较在不过期的情况下，肯定返回 true，只是用来判断过期吗？另外，signature 的作用体现在哪里？为什么随便造 token 中的 signature 也能登录成功呢？方便的话能解答一下，谢谢~

elasticsearchTemplate

Action:

Consider defining a bean named 'elasticsearchTemplate' in your configuration.

思维导图和pdm文件均打不开

添加Swagger-UI的配置代码示例有点小瑕疵

文档地址

这个注释有点小问题，个人测试的实际情况是。

//为有@ApiOperation注解的方法生成API文档
.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))

上述代码仅扫描 类上有无指定注解，
即如果类上有ApiOperation注解，会生成API文档。
又因为该注解只能在作用于方法。建议删除此逻辑。

关于docker-maven-plugin构建镜像时出错

你好，问下为啥我用docker-maven-plugin 构建镜像时报错呢，是有什么schema需要指定么 0 0

小建议

大佬发个支付宝、微信、PayPal 收款码吧，开源不易，大伙打赏才能让开源者的热情不会慢慢消磨殆尽。

I suggest you send a payment code of alipay, WeChat and PayPal. It is not easy to open source. Only by giving rewards can we keep the enthusiasm of open source users from fading away.

elasticsearch 批量导入

generatorConfig.xml的table节点中，为text类型单独增加类型转换，否则XXXExample中的SQL封装会丢失text类型字段

    <table tableName="pms_brand">
        <generatedKey column="id" sqlStatement="MySql" identity="true"/>
        <!-- 对应表中每一个类型为text的列 -->
        <columnOverride column="brand_story" jdbcType="VARCHAR"/>
    </table>

RabbitMQ延迟消息

教程中生成订单时会向死信队列发送消息，到期后向取消订单队列发送消息。如果订单未到期用户支付成功了，死信队列的消息该怎么办？

看了一下源码，支付成功回调函数并没有对死信队列做处理，取消订单也是暴露Api手动调用而不是自动超时取消。

mall-tiny-docker-file项目Dockerfile文件有一行内容是否为多余内容

在Dockerfile文件中RUN bash -c 'touch /mall-tiny-docker-file.jar'这一行代码是否为多余内容？如果不是多余内容它起到了什么作用。我在测试的时候Dockerfile中无论是否有这行内容最终打出来的镜像都可以正常运行并且可以访问。

redis那个是走了jedis的连接池吗？

Cannot resolve org.mongodb:mongodb-driver-core:3.8.2

关于功能模块的问题

这个商城项目还有很多功能未完善，比如评论管理之类的模块，不知道大佬可以分享一下这个吗？

Dockerfile中RUN bash -c 'touch /mall-tiny-docker-file.jar'这一行代码是否为多余内容？

如果不是多余内容它起到了什么作用。我在测试的时候Dockerfile中无论是否有这行内容最终打出来的镜像都可以正常运行并且可以访问。

验证码使用是否需要先经过jwt鉴权

mall-learning/mall-tiny-04/src/main/java/com/macro/mall/tiny/config/SecurityConfig.java

Line 64 in be50c93

    
           .antMatchers("/admin/login", "/admin/register")// 对登录注册要允许匿名访问

/sso路径用户验证码

找不到PasswordEncoder的Bean

在mall整合SpringSecurity和JWT实现认证和授权（二）中

Field passwordEncoder in com.csmaxwell.mall.service.impl.UmsAdminServiceImpl required a bean of type 'org.springframework.security.crypto.password.PasswordEncoder' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.security.crypto.password.PasswordEncoder' in your configuration.

在 UmsAdminServiceImpl 的

@Autowired
private PasswordEncoder passwordEncoder

这个Bean不是在 SecurityConfig中添加了吗？为什么会提示找不到呢？

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private UmsAdminService adminService;
    @Autowired
    private RestfulAccessDeniedHandler restfulAccessDeniedHandler;
    @Autowired
    private RestAuthenticationEntryPoint restAuthenticationEntryPoint;

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        ...
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService())
                .passwordEncoder(passwordEncoder());
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

使用源代码可以运行，我一一对比，发现只有一个地方不同：
这是作者的源代码 Security 的版本

这是我使用的 Security 版本

作者使用的是 2.1.3.RELEASE
是因为spring-boot-starter-security的版本不一样的原因吗？
希望能有大佬帮我解惑一下
--更新--
我把作者源代码更新到 2.1.13.RELEASE 现在版本一致，还是作者的代码可以运行，而我的一直说找不着这个 Bean，不要@Autowired注解，可以运行，但是链接都指向的 localhost:8080/login。
把作者的 passwordEncoder 方法上面的@bean去掉，报的错误就是一样的，所有是Spring没有找到这个Bean吗？

用户和角色的关联，在代码中有处理吗

用户和角色的绑定，在代码中有处理吗？还是直接在关系表中生成的，没有处理这块的逻辑

《mall在Linux环境下的部署（基于Docker Compose）》多余的步骤

这个『下载所有需要安装的Docker镜像』步骤似乎是多余的。

docker pull mysql:5.7
docker pull redis:3.2
#  略 略

因为作者已经在docker-compose-env.yml配置文件中的image: mysql:5.7声明过镜像来源和版本了。docker引擎是会自动帮你pull的。再执行上面的命令是多余的，相当于同样的代码出现了两次

docker远程访问问题

docker 开放2375端口是有安全问题的，请更改其他方法吧

jwt 这节遇到这个问题，看不出来哪里有问题。

您好，请问第一节中，PmsBrandServiceImpl 的 listBrand 方法，return 前是不是多写了一次查询，我不删除的话得不到正确的分页结果

swagger-ui界面测试token有点坑啊

根据教程在swagger界面测试登录成功之后获取了token，然后给请求加上token，之后测试获取所有权限接口，一直401（暂未登录或token已经过期），JwtAuthenticationTokenFilter的doFilterInternal打断点发现，request.getHeader(this.tokenHeader)获取为null，搞了半天没找到原因，后面用postman，请求头里面添加token之后调用，结果调用成功，超郁闷-_-

Jackson字符串反序列化问题

我在Mac上面做docker部署
按照教程里面，把该安装的工具都在docker里面pull好，版本也都一模一样
直到走到springboot部署这个环节，按照第二张图，双击mall-admin下面的package
然后console以报错终止
我在根目录mvn install也不行，具体我贴个图好了，应该是关于Jackson字符串反序列化的问题，具体到代码哪一块儿，我也不知道怎么找/Users/swj/Desktop/[email protected]

照着文档 package 构建mall-admin 项目的时候出现这个问题

设置 .antMatchers("/**").permitAll()为什么还要登录

在spring security中设置.antMatchers("/**").permitAll() //测试时全部允许访问，但进swagger UI里面不登录测试接口还是返回403，百思不得其解。。。。
