后端接收与发送XML数据
1 接收发送来的XML数据
1.1 普通XML
①postman发送请求，格式为XML
修改Content-Type格式为：text/xml或者application/xml
②后端接收
- 导入依赖
<!--XML解析--><dependency><groupId>com.fasterxml.jackson.dataformat</groupId><artifactId>jackson-dataformat-xml</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.24</version></dependency>
- 编写接收实体类
@Data@AllArgsConstructor@NoArgsConstructor@JacksonXmlRootElement(localName ="User")publicclassUser{@JacksonXmlProperty(localName ="name")privateString name;@JacksonXmlProperty(localName ="age")privateInteger age;}
- controller接收数据
@RestControllerpublicclassTestXMLController{@PostMapping("/testXML")publicStringtestXMLController(@RequestBodyUser user){System.out.println(user);return"testXML success";}}
- 结果：
User(name=curry, age=29)
1.2 复杂XML（嵌套）
①postman发送XML数据
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Root><head><provider>江南造汽场</provider><address>江南皮革厂旁边</address><date>2022-10-10 11:21:43</date></head><info><car><name>兰博基尼</name><type>敞篷跑车</type><count>10</count></car><car><name>法拉利</name><type>超跑</type><count>5</count></car></info></Root>
header选择：
Content-Type为application/xml
②后端解析XML数据
- 解析根标签【Root】
@Data@JacksonXmlRootElement(localName ="Root")@AllArgsConstructor@NoArgsConstructorpublicclassRootXml{@JacksonXmlElementWrapper(localName ="head")privateHeadInfo headInfo;@JacksonXmlElementWrapper(localName ="info")@JacksonXmlProperty(localName ="car")privateList<Car> carList;}
- 解析head标签
@Data@AllArgsConstructor@NoArgsConstructor@JacksonXmlRootElement(localName ="Root")publicclassHeadInfo{@JacksonXmlProperty(localName ="provider")privateString facName;@JacksonXmlProperty(localName ="address")privateString address;@JacksonXmlProperty(localName ="date")//也可以使用@DateTimeFormat注解转换,但无法精确到小时//此处也可以改成String,然后使用DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")转换@JsonFormat(pattern ="yyyy-MM-dd HH:mm:ss", timezone ="GMT+8")privateDate date;}
- 解析info标签
@Data@AllArgsConstructor@NoArgsConstructor@JacksonXmlRootElement(localName ="Root")publicclassCarInfos{@JacksonXmlElementWrapper(localName ="info")@JacksonXmlProperty(localName ="car")privateList<Car> carList;}
- 解析car标签
//车辆信息@AllArgsConstructor@NoArgsConstructor@DatapublicclassCar{@JacksonXmlProperty(localName ="name")privateString carName;@JacksonXmlProperty(localName ="type")privateString carType;@JacksonXmlProperty(localName ="count")privateInteger count;}
③编写controller接收XML并获取数据
produces = MediaType.APPLICATION_XML_VALUE, consumes = MediaType.APPLICATION_XML_VALUE
@PostMapping(value ="/parseXML", produces =MediaType.APPLICATION_XML_VALUE, consumes =MediaType.APPLICATION_XML_VALUE)publicStringparseXML(@RequestBodyRootXml rootXml){HeadInfo headInfo = rootXml.getHeadInfo();System.out.println("headInfo:"+ headInfo);List<Car> carList = rootXml.getCarList();for(Car car : carList){System.out.println(car);}return"parseXML success";}
④控制台信息
headInfo:HeadInfo(facName=江南造汽场, address=江南皮革厂旁边, date=MonOct1011:21:43CST2022)Car(carName=兰博基尼, carType=敞篷跑车, count=10)Car(carName=法拉利, carType=超跑, count=5)
2 后端发送XML数据
①导入依赖
<!--XML解析--><dependency><groupId>com.fasterxml.jackson.dataformat</groupId><artifactId>jackson-dataformat-xml</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.24</version></dependency>
②编写实体类
@Data@AllArgsConstructor@NoArgsConstructor@JacksonXmlRootElement(localName ="User")publicclassUser{@JacksonXmlProperty(localName ="name")privateString name;@JacksonXmlProperty(localName ="age")privateInteger age;}
③编写controller
注解上添加：produces = MediaType.APPLICATION_XML_VALUE
@RestControllerpublicclassTestXMLController{@PostMapping(value ="/sendXML", produces =MediaType.APPLICATION_XML_VALUE)publicUsersendXML(){User user =newUser();
user.setName("徐杰");
user.setAge(18);return user;}}

④postman发起请求，查看返回结果
