[GitHub] [dubbo] yipixiaofeiyang opened a new issue #8359: Could not resolve placeholder 'dubbo.application' in value "${dubbo.application}"
yipixiaofeiyang opened a new issue #8359:
URL: https://github.com/apache/dubbo/issues/8359
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 3.0.1
* Spring 5.3.9
* Java version: 1.8
### Steps to reproduce this issue
最近发现dubbo3.0已经发布好久了,而且也已经第三个版本了. 遂考虑将本地的dubbo-2.7.8升级到3.0.1, 可再项目启动的收报

at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:392)`
将dubbo降到2.7.8又能正常启动, 有谁碰到这个问题没? 可以排除的问题:
1:key值拼写错误
2:本地自定义spring-*.xml中有多套PropertySources被初始化
Pls. provide [GitHub address] to reproduce this issue.

用法有点怪。。建议3.0中直接使用注解配置或者properties配置

感觉是因为dubbo提前加载了PropertyPlaceholder, 导致了spring的PropertySourcesPlaceholderConfigurer没起作用

@kevinw66 @kylixs 我今天在继续探索3.0的升级过程中, 又发现了个问题. 也和PropertySourcesPropertyResolver相关, 在原有的简易demo上引入了三方sdk, 比如aliyun-oss, 其中也有变量引入${aaa}, 如果采用
<bean id="propertiesUtil" class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer"></bena>的方式不会报错, 但是采用自定义类集成PropertySourcesPlaceholderConfigurer,如:
<bean id="propertiesUtil" class="com.wqh.demo.dobbo3.PropertiesUtil">
又会引发上面的(Could not resolve placeholder)问题,
同样, 我把版本回到2.7.8 程序又能正常运行! 请原谅我三番五次的对比和折磨! 因为这对我的项目很重要!
详情可以参考下面改进后的demo

好的感谢了! 这对于springmvc用户将是个硬伤, 多环境下的properies变量就需要改造了, 这个问题, 要是后续版本能解决, 将会使现有系统升级更加平滑!

@yipixiaofeiyang 这是一个bug，下个版本解决，请指定一个id或者用属性配置方法：
```xml
<dubbo:application id="application1" name="${dubbo.application}">
<dubbo:parameter key="qos.enable" value="false" />
</dubbo:application>
```
或者改为属性配置：
```
dubbo.application.name=wqh-app
dubbo.application.qos-enable=false
```

看了一下，这种用法一直是有问题的。2.7.8不会报错是因为注册的时候直接把beanName设置成了`${dubbo.application}`，而3.0.1里去尝试解析这个变量，发现解析不了就报错了

[GitHub] [dubbo] yipixiaofeiyang edited a comment on issue #8359: Could not resolve placeholder 'dubbo.application' in value "${dubbo.application}"(dubbo 3.0+)

@kevinw66 @kylixs 我今天在继续探索3.0的升级过程中, 又发现了个问题. 也和PropertySourcesPropertyResolver相关, 在原有的简易demo上引入了三方sdk, 比如aliyun-oss, 其中也有变量引入${aaa}, 如果采用
`<bean id="propertiesUtil" class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer"></bena>`
的方式不会报错, 但是采用自定义类集成PropertySourcesPlaceholderConfigurer,如:
`<bean id="propertiesUtil" class="com.wqh.demo.dobbo3.PropertiesUtil">`
又会引发上面的(Could not resolve placeholder)问题,
同样, 我把版本回到2.7.8 程序又能正常运行! 请原谅我三番五次的对比和折磨! 因为这对我的项目很重要!
详情可以参考下面改进后的demo

id或者name配置直接写上，别使用占位符应该是可以的

本地也尝试了一下，没办法复现，能否麻烦提供一个demo呢？

这也是spring的标准玩法, 其它框架和spring整合这样是没问题的, 基于这种情况, 用什么方式可以过渡或者运行起来呢?
