com.alibaba.dubbo.qos.server.DubboLogo 这个类的maven坐标是什么？

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot</artifactId>
            <version>1.5.6.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>

            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>2.0.0</version>
        </dependency>

或者用新的项目都是报一样的错：

        <dependency>
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.1.0</version>
        </dependency>

报错信息：

用旧的版本是正常的：

        <dependency>
            <groupId>com.alibaba.spring.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>1.0.0</version>
        </dependency>

因为旧的版本有些问题，打算升下版本看看有没有解决这些问题：

  1. 无法禁止启动前检查
  2. 在父类里，使用注解不会注入 ...

It's not a official release , please replace

    <artifactId>dubbo-spring-boot-starter</artifactId>
