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 java.io.StringReader;import java.nio.charset.StandardCharsets;import org.apache.commons.io.IOUtils;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.io.SAXReader;import org.junit.jupiter.api.BeforeAll;import org.junit.jupiter.api.Test;import org.springframework.core.io.ClassPathResource;import org.springframework.core.io.Resource;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;@Slf4jpublic class XmlTest{
static JsonMapper jsonMapper = new JsonMapper();
static XmlMapper xmlMapper = new XmlMapper();
static WebClient webClient = WebClient.builder().codecs(configurer -> configurer.defaultCodecs().maxInMemorySize(-1)).build();
@Test
public 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xml
JsonNode jsonNode = jsonMapper.readTree(jsonText);
String xml = xmlMapper.writerWithDefaultPrettyPrinter().writeValueAsString(jsonNode);
// dom4j、XPath
Document 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
