@PostMapping(value = "/testXmlRequest", 
     produces = "application/xml; charset=UTF-8", 
     consumes = "application/xml; charset=UTF-8")
     public UserDto testXmlRequest(@RequestBody UserDto dto){
        dto.chgName("2342424sdfsdfsdf");
        return dto;
    }

produces 設置響應的數據格式。最終httpMessageConverter根據produces的響應media-type來選擇對應的轉換類。

實體類

@XmlRootElement(name = "xml")
public class UserDto {
    @XmlElement(name = "id")
    private Integer id;
    @XmlElement(name = "name")
    private String name;
    @XmlElement(name = "sex")
    private Integer sex;

    public UserDto() {
    }

    public UserDto(Integer id, String name, Integer sex) {
        this.id = id;
        this.name = name;
        this.sex = sex;
    }

    public void chgName(String name){
        this.name = name;
    }
}
 

javax.xml.bind.annotation.*的相關註解。會自動封裝和解析。註意：對應的field不能有getter和setter，不然會報錯。
因此，通常對於屬性的設置，創建對應的builder類就可以了。

例子

headers:Content-Type=application/xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xml>
    <id>12131</id>
    <name>test</name>
    <sex>1</sex>
</xml>
 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xml>
    <id>12131</id>
    <name>2342424sdfsdfsdf</name>
    <sex>1</sex>
</xml>
