http调用webservice

Posted 2022-11-23 一枚新人小菜鸡

首先引用依赖pom

 <!-- 如果使用的是 springframework的RestTemplate发送http,那么需要引入此依赖-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>

		<!-- 
		          使用apache的httpclient发送http,需要引入httpclient依赖;
		          使用OMElement需要引入axis2-transport-http依赖;改以来本身带有httpclient依赖,所以
		                 我们不在需要单独引入httpclient依赖了
		 -->
		<dependency>
			<groupId>org.apache.axis2</groupId>
			<artifactId>axis2-transport-http</artifactId>
			<version>1.7.8</version>
		</dependency>

		<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpclient</artifactId>
			<version>4.5.6</version>
		</dependency>

		<!-- https://mvnrepository.com/artifact/jaxen/jaxen Xpath解析包-->
		<dependency>
			<groupId>jaxen</groupId>
			<artifactId>jaxen</artifactId>
			<version>1.1.6</version>
		</dependency>
		<dependency>
			<groupId>org.json</groupId>
			<artifactId>json</artifactId>
			<version>20170516</version>
		</dependency>
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>fastjson</artifactId>
			<version>1.2.70</version>
		</dependency>
		<!-- https://mvnrepository.com/artifact/dom4j/dom4j -->
		<dependency>
			<groupId>dom4j</groupId>
			<artifactId>dom4j</artifactId>
			<version>1.6.1</version>
		</dependency>
</dependencies>

 

 

http请求这里用到了 工具类是 http请求webservice接口的工具类和获取到的数据xml转成json数据
