我要评论前言
springboot可以返回xml数据格式
xml数据格式
本文使用的是springboot3.4.x版本以上以及jdk17以上，由于在jdk9版本以后javax包被移动并更名为 jakarta，因此使用包如下
<!-- https://mvnrepository.com/artifact/jakarta.xml.bind/jakarta.xml.bind-api -->
<dependency>
<groupid>jakarta.xml.bind</groupid>
<artifactid>jakarta.xml.bind-api</artifactid>
<version>4.0.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-runtime -->
<dependency>
<groupid>org.glassfish.jaxb</groupid>
<artifactid>jaxb-runtime</artifactid>
<version>4.0.5</version>
</dependency>
实体类配置
import jakarta.xml.bind.annotation.xmlelement;
import jakarta.xml.bind.annotation.xmlrootelement;
@xmlrootelement
public class user {
@xmlelement
private long id;
@xmlelement
private string username;
@xmlelement
private integer age;
public long getid() {
return id;
}
public void setid(long id) {
this.id = id;
}
public string getusername() {
return username;
}
public void setusername(string username) {
this.username = username;
}
public integer getage() {
return age;
}
public void setage(integer age) {
this.age = age;
}
public user(long id, string username, integer age) {
this.id = id;
this.username = username;
this.age = age;
}
@override
public string tostring() {
return "user{" +
"id=" + id +
", username='" + username + ''' +
", age=" + age +
'}';
}
}接口层配置
@restcontroller
public class usercontroller {
@getmapping(value = "/getjson", produces = mediatype.application_json_value)
public user getjson() {
user user = new user(2l, "asdas1", 15);
return user;
}
@getmapping(value = "/getxml", produces = mediatype.application_xml_value)
public user getxml() {
user user = new user(1l, "hello", 12);
return user;
}
}
xml返回
一开始，调用
http://ip:端口/getxml
抛出异常，异常如下
后面调试源码异常信息，发现需要一个无参构造器，因此在实体类加上无参构造函数
import jakarta.xml.bind.annotation.xmlelement;
import jakarta.xml.bind.annotation.xmlrootelement;
@xmlrootelement
public class user {
@xmlelement
private long id;
@xmlelement
private string username;
@xmlelement
private integer age;
public long getid() {
return id;
}
public void setid(long id) {
this.id = id;
}
public string getusername() {
return username;
}
public void setusername(string username) {
this.username = username;
}
public integer getage() {
return age;
}
public void setage(integer age) {
this.age = age;
}
public user() {
}
public user(long id, string username, integer age) {
this.id = id;
this.username = username;
this.age = age;
}
@override
public string tostring() {
return "user{" +
"id=" + id +
", username='" + username + ''' +
", age=" + age +
'}';
}
}然后调用接口发觉还是异常
然后发觉异常信息为
发觉该包会从成员变量以及get方法中获取变量，因此重复了，就异常了，
解决方法如下
更改get方法名称
import jakarta.xml.bind.annotation.xmlelement;
import jakarta.xml.bind.annotation.xmlrootelement;
@xmlrootelement
public class user {
@xmlelement
private long id;
@xmlelement
private string username;
@xmlelement
private integer age;
public long getid1() {
return id;
}
public void setid(long id) {
this.id = id;
}
public string getusername1() {
return username;
}
public void setusername(string username) {
this.username = username;
}
public integer getage1() {
return age;
}
public void setage(integer age) {
this.age = age;
}
public user() {
}
public user(long id, string username, integer age) {
this.id = id;
this.username = username;
this.age = age;
}
@override
public string tostring() {
return "user{" +
"id=" + id +
", username='" + username + ''' +
", age=" + age +
'}';
}
}访问之后返回
使用@xmlaccessortype
@xmlrootelement
@xmlaccessortype(xmlaccesstype.field)
public class user {
@xmlelement
private long id;
@xmlelement
private string username;
@xmlelement
private integer age;
public long getid() {
return id;
}
public void setid(long id) {
this.id = id;
}
public string getusername() {
return username;
}
public void setusername(string username) {
this.username = username;
}
public integer getage() {
return age;
}
public void setage(integer age) {
this.age = age;
}
public user() {
}
public user(long id, string username, integer age) {
this.id = id;
this.username = username;
this.age = age;
}
@override
public string tostring() {
return "user{" +
"id=" + id +
", username='" + username + ''' +
", age=" + age +
'}';
}
}在类上加上 @xmlaccessortype(xmlaccesstype.field) 注解，加上此注解后，xml的访问类型为成员变量，而不是getter/setter方法
备注: 返回xml时，需要加上这个
produces = mediatype.application_xml_value
