Question

@POST
@Path("/getmethod")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_XML)
Response getMethod(SomeVO someVO);

在我的* .ear中,我可以看到resteasy-jaxb-provider-2.2.0.GA.jar和resteasy-jaxrs-2.2.1.GA.jar都存在,但在尝试访问此方法时,我遇到此错误:

我没有在VO类属性中添加注释.

样品:

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

@XmlRootElement(name = "user")
public class TestVo {

    String order;
    String serial;
    int number;

    @XmlElement
    public String getorder() {
        return order;
    }

    public void setorder(String order) {
        this.order = order;
    }

    @XmlElement
    public String getserial() {
        return serial;
    }

    public void setserial(String serial) {
        this.serial = serial;
    }

    @XmlAttribute
    public int getnumber() {
        return number;
    }

    public void setnumber(int number) {
        this.number = number;
    }

}
