一、概述

接上篇 java解析json复杂数据的两种思路
我们已经通过解析返回json字符串得到数据,现在改变思路, 按照如下流程获取数据:

二、数据预览

1. 接口json数据

三、代码实现

1. pom.xml

<dependency><groupId>org.springframework</groupId><artifactId>spring-webflux</artifactId><version>5.2.3.RELEASE</version></dependency><dependency><groupId>io.projectreactor.netty</groupId><artifactId>reactor-netty</artifactId><version>0.9.4.RELEASE</version></dependency><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-slf4j-impl</artifactId><version>2.12.1</version></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>3.10</version></dependency><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.5</version></dependency><dependency><groupId>com.fasterxml.jackson.dataformat</groupId><artifactId>jackson-dataformat-xml</artifactId><version>2.10.2</version></dependency><dependency><groupId>org.dom4j</groupId><artifactId>dom4j</artifactId><version>2.1.4</version></dependency><dependency><groupId>jaxen</groupId><artifactId>jaxen</artifactId><version>2.0.0</version></dependency><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-api</artifactId><version>5.5.2</version><scope>test</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.12</version><scope>provided</scope></dependency>

2. 核心代码

package com.fly.xml;import java.io.IOException;

import org.dom4j.Document;

import org.springframework.core.io.ClassPathResource;

import org.springframework.http.MediaType;
import org.springframework.web.reactive.function.client.WebClient;import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.json.JsonMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;import lombok.extern.slf4j.Slf4j;@Slf4j
public class XmlTest
{static JsonMapper jsonMapper = new JsonMapper();static XmlMapper xmlMapper = new XmlMapper();static WebClient webClient = WebClient.builder().codecs(configurer -> configurer.defaultCodecs().maxInMemorySize(-1)).build(); @Testpublic void testApi()throws IOException, DocumentException{//WebClient同步调用String url = "https://blog.csdn.net/community/home-api/v1/get-business-list?page=1&size=5&businessType=blog&username=qq_16127313";String jsonText = webClient.get().uri(url).acceptCharset(StandardCharsets.UTF_8).accept(MediaType.APPLICATION_JSON).retrieve().bodyToMono(String.class).block();//json转xmlJsonNode jsonNode = jsonMapper.readTree(jsonText);String xml = xmlMapper.writeValueAsString(jsonNode);// dom4j、XPathDocument doc = new SAXReader().read(new StringReader(xml));doc.selectNodes("//data/list/url").stream().forEach(n -> log.info(n.getStringValue()));doc.selectNodes("//data/list/viewCount").stream().forEach(n -> log.info(n.getStringValue()));}
}

3. 运行结果

四、源码传送
