rest - jaxrs-ri-2.30 在使用 Java 12 在 Tomcat 9 中运行 REST Web 服务时未将 xml 转换为 Pojo

Question

我在本地安装的 tomcat 9 中运行带有 JAX-RS 实现的 Rest web 服务，并在我的系统中安装了 Java 12。我可以使用 JSON 有效负载调用接受 POST 请求的方法。但无法使用 XML 有效负载调用相同的方法。

需要帮助来解决此问题。

以下是我的项目详情：

Tomcat version  :   9.0.31 (Installed locally)

Java version    :   12

pom.xml 依赖项：

<dependencies>
    <dependency>
        <groupId>org.glassfish.jersey.bundles</groupId>
        <artifactId>jaxrs-ri</artifactId>
        <version>2.30</version>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

部署描述符（web.xml）：

  <servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
      <param-name>jersey.config.server.provider.packages</param-name>
      <param-value>webservices</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/webapi/*</url-pattern>
  </servlet-mapping>

客户 Pojo (Customer.java)：

package domain;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Customer {
    private int id;

    private String country;

    @XmlAttribute
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    @XmlElement
    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    @XmlElement
    public String getLastName() {
        return lastName;

    }

    @XmlElement
    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    @XmlElement
    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    @XmlElement
    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }

    @XmlElement
    public String getZip() {
        return zip;
    }

    public void setZip(String zip) {
        this.zip = zip;
    }

    @XmlElement
    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    @Override
    public String toString() {
        return "Customer{" + "id=" + id + ", firstName='" + firstName + '\'' + ", lastName='" + lastName + '\''
                + ", street='" + street + '\'' + ", city='" + city + '\'' + ", state='" + state + '\'' + ", zip='" + zip
                + '\'' + ", country='" + country + '\'' + '}';
    }
}
