首先需要在pom中添加对应包信息

<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.13</version>
</dependency>
<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>2.0.23</version>
</dependency>
<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpcore</artifactId><version>4.4.15</version>
</dependency>
<dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>2.0.7</version>
</dependency>
