将xml解析指定的JavaBean

1.依赖

<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.8.11</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.11</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.dataformat</groupId> <artifactId>jackson-dataformat-xml</artifactId> <version>2.8.11</version> </dependency>

2.xml转Object 

xml

讯享网<?xml version="1.0" encoding="utf-8"?> <student> <*****>北京三里屯</*****> <studentName>张三</studentName> <nainling>25</nainling> <dh></dh> <rs> <array> <acc01>89.50</acc01> <acc02>100.00</acc02> <acc03>91.00</acc03> </array> <array> <acc01>78.50</acc01> <acc02>69.00</acc02> <acc03>88.90</acc03></array> </rs> </student> 

JavaBean 

@JacksonXmlProperty注解是标注该属性在xml中对应的节点名称，这就是为了解决某某系统接口字段命名不规范的利器

 base

package cn.gogpay.dcb.socialsecurity.xml; import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty; / * {描述} * * @author  * @date 2018/7/24 11:45 */ public class Base { @JacksonXmlProperty(localName = "*****") private String address; public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } } 

 student

@JacksonXmlRootElement 这个注解是指名根节点

@JacksonXmlElementWrapper将某节点下单元素解析为Array或者Collection类型，因为除了公共字段外，其他字段都可能是变化的所以在集合哪儿使用了泛型

score

 Test

讯享网 String xml = "<?xml version=\"1.0\" encoding=\"gb2312\" standalone=\"yes\"?><student><*****>北京三里屯</*****><studentName>张三</studentName><nainling>25</nainling><dh></dh><rs><array><acc01>89.50</acc01><acc02>100.00</acc02><acc03>91.00</acc03></array><array><acc01>78.50</acc01><acc02>69.00</acc02><acc03>88.90</acc03></array></rs></student>"; ObjectMapper objectMapper = new XmlMapper(); Student<Score> student = objectMapper.readValue(xml, Student.class); System.out.println(student); String result = objectMapper.writeValueAsString(student); System.out.println(result);

 输出结果
