自定义启动器在1.5.20生效，但在2.0之后无效，并发生错误

Question

我自定义了springboot启动程序，该代码在1.5.20版中生效，但在2.0版之后不起作用（我已经在2.0.9、2.1.1和2.1.4版上进行了测试）。

启动器的v1.x.x和v2.x.x有什么区别？

我应该怎么做才能使其在2.x.x版本上正确？

我创建了两个maven项目和一个spring starter项目，这些项目如下：

第一个名为“ share”的项目，它充当第三方jar。

第二个项目名为“ share-spring-boot-starter”，它取决于“ share”的罐子。

第三个项目名为“ springboot-demo”，它充当一个Web项目，取决于“ share-spring-boot-starter”的jar。

注意：第一个项目和第二个项目的jar由命令mvn clean install构建，并由mvn install:install-file -Dfile=xxx ...将jar安装到本地Maven存储库。

有关“共享”项目的代码：

ShareDemo.java

package com.example;

import com.alibaba.fastjson.JSONObject;

public class ShareDemo {

    private String name;

    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String doSomeThing() {
        return this.toString();
    }

    @Override
    public String toString() {
        return JSONObject.toJSONString(this);
    }

}

这些项目的所有代码都可以在这里找到：https://github.com/biaotang/custom-spring-boot-starter

我想在2.x.x版本上运行这些代码，但是它不起作用，并且在“ springboot-demo”项目中发生了编译错误

  @Autowired
  ShareDemo shareDemo;  // can't be resovle the type
