## 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

<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")
    public class User {
        
        @JacksonXmlProperty(localName = "name")
        private String name;
    
        @JacksonXmlProperty(localName = "age")
        private Integer age;
    }

*  controller接收数据

@RestController
    public class TestXMLController {
        
    
        @PostMapping("/testXML")
        public String testXMLController(@RequestBody User 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
    @NoArgsConstructor
    public class RootXml {
        
        @JacksonXmlElementWrapper(localName = "head")
        private HeadInfo headInfo;
    
        @JacksonXmlElementWrapper(localName = "info")
        @JacksonXmlProperty(localName = "car")
        private List<Car> carList;
    }

*  解析head标签

@Data
    @AllArgsConstructor
    @NoArgsConstructor
    @JacksonXmlRootElement(localName = "Root")
    public class HeadInfo {
        
    
        @JacksonXmlProperty(localName = "provider")
        private String facName;
    
        @JacksonXmlProperty(localName = "address")
        private String 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")
        private Date date;
    }

*  解析info标签

@Data
    @AllArgsConstructor
    @NoArgsConstructor
    @JacksonXmlRootElement(localName = "Root")
    public class CarInfos {
        
    
        @JacksonXmlElementWrapper(localName = "info")
        @JacksonXmlProperty(localName = "car")
        private List<Car> carList;
    
    }

*  解析car标签

//车辆信息
    @AllArgsConstructor
    @NoArgsConstructor
    @Data
    public class Car {
        
    
        @JacksonXmlProperty(localName = "name")
        private String carName;
    
        @JacksonXmlProperty(localName = "type")
        private String carType;
    
        @JacksonXmlProperty(localName = "count")
        private Integer 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)
    public String parseXML(@RequestBody RootXml 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=Mon Oct 10 11:21:43 CST 2022)
    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

②编写实体类

③编写controller

> 注解上添加：produces = MediaType.APPLICATION\_XML\_VALUE

@RestController
    public class TestXMLController {
        
    	@PostMapping(value = "/sendXML", produces = MediaType.APPLICATION_XML_VALUE)
        public User sendXML(){
        
            User user = new User();
            user.setName("徐杰");
            user.setAge(18);
            return user;
        }
    }

④postman发起请求，查看返回结果
