Description:
A component required a bean of type 'com.lsh.demo.basic.strategy.PayService' that could not be found.
Action:
Consider defining a bean of type 'com.lsh.demo.basic.strategy.PayService' in your configuration.
Process finished with exit code 1

Exception encountered during context initialization -
cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'projectOrderController':

expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations: {@javax.annotation.Resource(shareable=true, lookup=, name=, description=, authenticationType=CONTAINER, type=class java.lang.Object, mappedName=)}
解决:@ComponentScan 加上该类路径,OK
@ComponentScan(basePackages = {"com.demo.xxx.xxx"})
@ComponentScan 添加包时,如果不能识别其他module的包,检查pom文件是否引入
分析:springboot默认扫描规则:自动扫描启动器类的同包或者其子包的下的注解

超过dubbo限制 – 默认是8M
传输大文件效率
多种格式不支持等等
解惑:1.下载改为返回前端url自行下载
2.dubbo中的 hessian
3.oss中有专门的处理大文件方式-分片上传和断点续传

@Reference 必须是 com.alibaba.dubbo.config.annotation.Reference ,引用错误
重名的有 :jdk.nashorn.internal.ir.annotations.Reference
通过idea可以选择

实现Serial接口
提供dubbo给第三方使用时,最好在本地,新建一个项目 + 新建maven 仓库来测试
1、查看maven仓库,jar都存在,删除重新下载试试
报错信息:
Failed to read artifact descriptor for com.fliggy.xxx-client:jar:1.0.0-SNAPSHOT Failed to read artifact descriptor for com.fliggy.xxx-domain:jar:1.0.0-SNAPSHOT Failed to read artifact descriptor for com.fliggy.xxx-client:jar:1.0.0-SNAPSHOT less... (Ctrl+F1)
Inspection info: Inspects a Maven model for resolution problems.
2、通过本地 project structure 引入本地的jar,能使得项目中不报错,但是install 找不到包,项目也无法启动
3、pom文件补全引用,install报错:
[ERROR] Failed to execute goal on project bootstone-web: Could not resolve dependencies for project com.lsh.demo:bootstone-web:war:1.1.1-SNAPSHOT: Failed to collect dependencies at com.fliggy.jvopf:jvopf-domain:jar:1.0.0-SNAPSHOT: Failed to read artifact descriptor for com.fliggy.jvopf:jvopf-domain:jar:1.0.0-SNAPSHOT: Failure to find com.fliggy.jvopf:jvopf:pom:1.0.0-SNAPSHOT in http://116.62.8.239:8082/repository/3rd-party-snapshot/ was cached in the local repository, resolution will not be reattempted until the update interval of tbmirror-snapshots has elapsed or updates are forced -> [Help 1]
4、可能是子pom修改了版本号,父工程没更新?
暂时回退0.0.1版本
上传jar通过指定pom解决
mvn deploy:deploy-file -Dfile=xx-xx-1.0.0-SNAPSHOT.jar -DgroupId=com.xx.xx -DartifactId=boot-stone -Dversion=1.0.0-SNAPSHOT -Dpackaging=jar -Durl=http://xx:8082/repository/3rd-party-snapshot -DrepositoryId=sf -sD:/software/apache-maven-3.5.0-bin/apache-maven-3.5.0/conf/settings_rdc.xml -DpomFile=pom.xml
–成功,不需要指定D盘
mvn deploy:deploy-file -Dfile=xx-xx-1.0.0-SNAPSHOT.jar -DgroupId=com.xx.xx-DartifactId=xx-xx-Dversion=1.0.0-SNAPSHOT -Dpackaging=jar -Durl=http://xx:8082/repository/3rd-party-snapshot -DrepositoryId=sf -sD:/software/apache-maven-3.5.0-bin/apache-maven-3.5.0/conf/settings_rdc.xml -DpomFile=pom.xml
NoSuchMethodError 一般多为jar冲突,debug断点进去,或者全局搜索是否有重名类
Caused by: java.lang.NoSuchMethodError: com.alibaba.dubbo.common.utils.ConfigUtils.getSystemProperty(Ljava/lang/String;)Ljava/lang/String;
2019年2月18日复现:
!! hsf 包中重名类 方法 冲突!!
放开注释的pom文件即可,引用了本地的jar,但是pom文件还是需求

1、@service换@compent 无用
2、加 @lazy 无用
3、clean install 暴露问题
问题变为 本地引入的jar,install依然报错找不到类
1、加上pom文件来测试,ok
