【Spring Boot】发送post请求解析XML

这里采用短信发送作为案例，先发送post请求，然后解析xml。

1.导入Maven

pom.xml

<!– 解析xml –>
<!– https://mvnrepository.com/artifact/dom4j/dom4j –>
<dependency>
  <groupId>dom4j</groupId>
  <artifactId>dom4j</artifactId>
  <version>1.6.1</version>
</dependency>

2.编写发送请求和解析类

@Transactional(propagation = Propagation.REQUIRED, rollbackFor = { Exception.class })
public void sendMessage(Verification verification) {
// TODO 短信发送
    MultiValueMap<String, String> params = new LinkedMultiValueMap<>();
    params.add("userid", "");
    params.add("account", "");
    params.add("password", "");
    params.add("mobile", verification.getVoContent());
    params.add("content", "【笨猪网】您的验证码为["+verification.getVoVerification()+"]");
    params.add("action", "send");
    params.add("sendTime", "");
    params.add("extno", "");
    RestTemplate client = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    HttpMethod method = HttpMethod.POST;
// 以表单的方式提交
    headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
//将请求头部和参数合成一个请求
    HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(params, headers);
//执行HTTP请求，将返回的结构使用ResultVO类格式化
    ResponseEntity<String> response = client.exchange("请求的地址", method, requestEntity, String.class);
    String xml = response.getBody();
    try {
        Document dom = DocumentHelper.parseText(xml);
        Element root=dom.getRootElement();
//写入数据库记录，可以自己写
        this.messageInfoMapper.insertMessageInfo(new MessageInfo(null, verification.getVoContent(), root.element("returnstatus").getText(), root.element("message").getText(), root.element("taskID").getText(), DateUtil.getNow()));
    } catch (DocumentException e) {
// TODO 处理异常
        e.printStackTrace();
    }
}
