报错：
nested exception is java.lang.NoClassDefFoundError: okhttp3/ConnectionPool"

解决：
在pom.xml中添加依赖

        <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>okhttp</artifactId>
        </dependency>
        <dependency>
            <groupId>com.squareup.okio</groupId>
            <artifactId>okio</artifactId>
            <version>1.11.0</version>
        </dependency>
