《黑马头条》SpringBoot+SpringCloud+ Nacos等企业级微服务架构项目_黑马头条项目_软工菜鸡的博客-CSDN博客
各位爷，完整项目gitee如下，求star
heima-leadnews-master: 《黑马头条》项目采用的是SpringBoot+springcloud当下最流行的微服务为项目架构，配合spring cloud alibaba nacos作为项目的注册和配置中心。新课程采用快速开发的模式，主要解决真实企业开发的一些应用场景。详情请看博客：https://blog.csdn.net/m0_67184231/article/details/131439819
Day01
用他的 centos镜像 自动集成了 nacos 所有的配置 大部分都要改mysql密码啥的；
启动他的项目，有些时候要启动 redis 容器；镜像里面已经拉取好了；
直接输入
docker run -d --name redis --restart=always -p 6379:6379 redis --requirepass "leadnews"；
也可以看P84
Resource的logback都要改成对应的
读取C:\Users\{用户}\.m2\repository\org\lz4\lz4-java\1.7.1\lz4-java-1.7.1.jar时出错; error in opening zip file
这个jar包 重新去官网下载一遍：
https://mvnrepository.com/artifact/org.lz4/lz4-java/1.7.1
day02
Minio的模版有问题显示不正确！
他这里要导入basic微服务；才能引入file-starter
这个要在nacos里面配 minio；
?allowPublicKeyRetrieval=true 成功解决；
day03 文章发布
上来就有坑，还好我发现的早，脚本中没有建库语句，去day2拿过来改改
启动WemediaAplication.java微服务
day03的项目 还得开本地redis；不然报错
WARN o.s.b.a.r.RedisReactiveHealthIndicator - Redis health check failed
org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to localhost:6379
at org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory$ExceptionTranslatingConnectionProvider.translateException(LettuceConnectionFactory.java:1534)
at org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory$ExceptionTranslatingConnectionProvider.getConnection(LettuceConnectionFactory.java:1442)点击 收藏 功能 报错；
查了一下，71 代表id；自己写了一个方法加在：WmMaterialController.java
@GetMapping("/collect/{id}")
public ResponseResult collect(@PathVariable Long id){
if(id==null)
return ResponseResult.errorResult(0,"传输的收藏id为空");
WmMaterial wmMaterial = wmMaterialService.getById(id);
// System.out.println(wmMaterial);
wmMaterial.setIsCollection((short) 1);
wmMaterialService.updateById(wmMaterial);
return ResponseResult.okResult(wmMaterial);
}
运行成功！我真牛逼！
哦，原来是day3的作业；没给答案 但是全自己做完了捏
黑马头条 作业+解答 day03-自媒体文章发布 自媒体接口_软工菜鸡的博客-CSDN博客
文章管理 发布文章的业务WmNewsServiceImpl.java
这里少了一个问题——没有判断文章内部如果没有图片的情况！
我测验 发现 他应该是在前端实现了；不管是自动还是无图，都会加系统的默认图片；
day04
ApArticleServiceImpl.java的
saveArticle() 这个2.2方法缺少两行黄色背景的代码 判空的Bug；传入错误的id得不到apArticleContent
else {
//2.2 存在id 修改 文章 文章内容
//修改 文章
updateById(apArticle);
//修改文章内容
ApArticleContent apArticleContent = apArticleContentMapper.selectOne(Wrappers.
.eq(ApArticleContent::getArticleId, dto.getId()));
if(apArticleContent==null)//传的id不对的话 这个位置为null会报错
return ResponseResult.errorResult(PARAM_REQUIRE);
apArticleContent.setContent(dto.getContent());
apArticleContentMapper.updateById(apArticleContent);
}
这里出错的原因是没有jwt；重新启动项目，没刷新页面就直接点击功能了；报处理异常；
我的想法是在jwt验证里 加个抛出异常的提醒；
没看出来 成没成功；
内容安全，自动审核的东西大部分都没有测出效果，阿里云的接口换了 没用；
审核图片失败 说是图片下载不下来；
审核文本失败 我直接注释了
WmNewsAutoScanServiceImpl.java 的clientBean要加@Qualifier限定符
不然两个Client找不到用哪个
@Qualifier("com.heima.apis.article.IArticleClient")
@Autowired
private IArticleClient articleClient;
测试了一下 源码不能检测 标题的敏感词汇；加了个这： wmNews.getTitle()+
//自管理的敏感词过滤
boolean isSensitive = handleSensitiveScan(
wmNews.getTitle()+textAndImages.get("content"), wmNews);
P77生成静态文件失败
Day04 作业
Day05
测试连接redis
端口有问题
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'scheduleClient': Unsatisfied dependency expressed through field 'taskService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'taskServiceImpl': Invocation of init method failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:

### The error may exist in com/heima/schedule/mapper/TaskinfoMapper.java (best guess)
### The error may involve com.heima.schedule.mapper.TaskinfoMapper.selectList
### The error occurred
加这个 &allowPublicKeyRetrieval=true
org.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'; nested exception is java.lang.IllegalStateException: No group.id found in consumer config, container properties, or @KafkaListener annotation; a group.id is required when group management is used.
加group-id

mangoDB的删除，为啥报这个错？ 说是要反序列化

把21行的id getId打印一下，啥类型 没解决
真的逆天，前端传的和HistorySearchDto 类型对不上，改成String，拆JSON得到Id才能删除成功！困扰我两个小时cnm
ApUserSearchController.java
@PostMapping("/del")
public ResponseResult delUserSearch(@RequestBody String dto){
Map
String id = map.get("id");
return apUserSearchService.delUserSearch(id);
