Spring引导XML更改根元素名称

我编写了一个spring boot应用程序来接受Http get Request并发送XML响应作为输出.我需要通过HTTP获取以下XML作为输出

    235
    345.0

而我的DTO课程如下,

@XmlRootElement(name = "response")
public class CgPayment {
    @XmlElement
    private String userId;
    @XmlElement
    private double amount;

    @XmlElement
    public String getUserId() {
        return userId;
    }

    @XmlElement
    public void setUserId(String userId) {
        this.userId = userId;
    }

    @XmlElement
    public void setAmount(double amount) {
        this.amount = amount;
    }

    @XmlElement
    public double getAmount() {

        return amount;
    }
}

但是我得到了以下响应作为输出.

    235
    345.0

如何更改根元素.响应类型为APPLICATION_XML_VALUE

您正在使用JAXB特定注释,但Jackson会对您的响应进行编组.要使JAXB注释与Jackson一起使用,您必须将其包含在jackson-module-jaxb-annotations内部pom.xml

    com.fasterxml.jackson.module
    jackson-module-jaxb-annotations

此外,您必须注册JaxbAnnotationModule您的配置.我认为使用Spring Boot实现这一目标的最简单方法是注册org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer类似于这样的Bean :

@Component
public class JacksonCustomizer implements Jackson2ObjectMapperBuilderCustomizer {
    @Override
    public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {
        jacksonObjectMapperBuilder.modulesToInstall(new JaxbAnnotationModule());
}

要么

@Bean
Jackson2ObjectMapperBuilderCustomizer jacksonCustomizer() {
    return (mapperBuilder) -> mapperBuilder.modulesToInstall(new JaxbAnnotationModule());
}
