jax b 2 IllegalAnnotationExceptions计数

Question

我想从pojo创建xml字符串。 我有一个以下pojo类

 @XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = { "companyType", "leadType" })
@XmlRootElement(name = "EnrichmentPayload", namespace = "http://www.example.org/EnrichmentPayload_LM_2.0")
public class Schema {
    @XmlElement(name = "CompanyType", required = true)
    CompanyType companyType;
    @XmlElement(name = "LeadType", required = true)
    LeadType leadType;

    public CompanyType getCompanyType() {
        return companyType;
    }

    public void setCompanyType(CompanyType companyType) {
        this.companyType = companyType;
    }

    public LeadType getLeadType() {
        return leadType;
    }

    public void setLeadType(LeadType leadType) {
        this.leadType = leadType;
    }

我有两个类CompanyType和LeadType，我也想要命名空间，

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="CompanyType")
public class CompanyType {
    @XmlElement(required=true)
    boolean threshold_met;
    @XmlElement(required=true)
    boolean isActive;
    @XmlElement(required=true)
    String company_id;
...
}

和潜在客户类型

    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "CompanyType")
    public class LeadType {
        @XmlElement(required = true)
        boolean threshold_met;
        @XmlElement(required = true)
        int lead_id;
        @XmlElement(required = true)
...
}

现在我正在以这种方式编组根元素：

JAXBContext jc = JAXBContext.newInstance(com.ss.dain.xmlcreator.Schema.class);

            Marshaller marshaller = jc.createMarshaller();
            //marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            marshaller.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "http://www.example.org/EnrichmentPayload_LM_2.0");
            // marshaller.setProperty("com.sun.xml.internal.bind.NameSpacePrefixMapper",
            // new NameSpaceMapper());
            StringWriter sw = new StringWriter();
            marshaller.marshal(schema, sw);
            xmlString = sw.toString();

在创建新实例时抛出异常

  

JAXBContext.newInstance（com.ss.dain.xmlcreator.Schema.class）;
