经历2.7.8坑后，好不容易等来个2.7.9，结果升级整合报错，望指点指点

[pangshuqiang]

环境：
springboot：2.3.7.RELEASE
springcloud：Hoxton.SR9
springcloudalibaba：2.2.5.RELEASE
nacos：1.4.1

正常情况下，springcloudalibaba-2.2.5.RELEASE里自带的事2.7.8版本的Dubbo，该版本下项目是能运行OK。

由于小马哥告知有新版，所以想单独替换Dubbo为2.7.9，调整后内容如下：
<dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>2.7.8</version> <exclusions> <exclusion> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo</artifactId> <version>2.7.9</version> </dependency>

但是运行直接报错：

这个
Caused by: java.lang.NoSuchMethodError: org.apache.dubbo.config.spring.context.DubboLifecycleComponentApplicationListener: method <init>()V not found

是个啥？大神指点指点一下，谢谢！！

[lucifer0x1]

version 2.7.9
package : org.apache.dubbo.config.spring.contex
DubboLifecycleComponentApplicationListener.java line 54

public DubboLifecycleComponentApplicationListener(ApplicationContext applicationContext) {
    super(applicationContext);
}

这里个构造方法是有参数的， 那么就没有默认的无惨构造方法了，

在 2.7.8中没有上面的方法，所以有无参构造方法
临时解决办法 是在 DubboLifecycleComponentApplicationListener 加上无参构造方法

public DubboLifecycleComponentApplicationListener( ) {

}

谢谢~~

修改源码还真没玩过，也好给需要的同学指点思路，期待Dubbo后续的完善。

哥们已经打算弃坑了。越改问题越多；还不如停留在当当网那个版本

[pangshuqiang]

感谢及时出了 org-apache-dubbo-start-2.7.9，目前使用该版本启动正常，项目比之前稳定很多~~

[AlbumenJ]

最新版本 2.7.10 已经向前兼容旧版本 starter，同时对于的 2.7.10 的 starter 也已经发布（starter 暂不向前兼容 Dubbo）。关于启动问题的 2.7.9 版本 starter 已经发布。
