把fastjson换成最新版本就好了

 替换之前
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.20</version>
        </dependency>
替换后
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.54</version>
        </dependency>
 替换成最新版本，就好了
 一定要确认好对应依赖版本

(20200916 Solved)docker-compose up创建容器自动退出
