一个比我更有经验的人能看看这个，告诉我我错过了什么吗？xsd中是否有需要更正的内容，或者JAXB中是否存在错误

更新 布莱斯完全回答了这个问题。不幸的是，IMHO，这使得JAXB一文不值。整个想法是，我可以从一个模式生成类——我不必事先知道关于结构的东西。如果我必须创建一个自定义绑定文件，我还可以创建一个模式来生成我想要的代码。但是，为什么要到此为止？为什么不跳过所有这些步骤，生成我想要的类呢

最后，一位同事向我指出，这个项目有点老，但它创建对象没有问题。Codehaus也有一个解决方案。

有几个枚举值导致了这个问题。这些问题可以通过使用JAXB外部绑定文件来克服（见下文）

枚举问题#1-空字符串

某些枚举值为空字符串（“”），这会导致生成字符串而不是枚举属性：

<xs:enumeration value="">
    <xs:annotation>
        <xs:documentation>Blank</xs:documentation> 
    </xs:annotation>
</xs:enumeration>

<xs:enumeration value="6">
    <xs:annotation>
        <xs:documentation>6th grade</xs:documentation> 
   </xs:annotation>
</xs:enumeration>

package gov.hhs.acf.nytd;

import javax.xml.bind.annotation.XmlEnum;
import javax.xml.bind.annotation.XmlEnumValue;
import javax.xml.bind.annotation.XmlType;

@XmlType(name = "educationLevelType")
@XmlEnum
public enum EducationLevelType {

    @XmlEnumValue("under 6")
    UNDER_6("under 6"),

    @XmlEnumValue("6")
    SIX("6"),

    @XmlEnumValue("7")
    SEVEN("7"),

    @XmlEnumValue("8")
    EIGHT("8"),

    @XmlEnumValue("9")
    NINE("9"),

    @XmlEnumValue("10")
    TEN("10"),

    @XmlEnumValue("11")
    ELEVEN("11"),

    @XmlEnumValue("12")
    TWELVE("12"),

    @XmlEnumValue("post secondary")
    POST_SECONDARY("post secondary"),

    @XmlEnumValue("college")
    COLLEGE("college"),
    @XmlEnumValue("")

    BLANK("");
    private final String value;

    EducationLevelType(String v) {
        value = v;
    }

    public String value() {
        return value;
    }

    public static EducationLevelType fromValue(String v) {
        for (EducationLevelType c: EducationLevelType.values()) {
            if (c.value.equals(v)) {
                return c;
            }
        }
        throw new IllegalArgumentException(v);
    }

}
这将导致生成以下枚举：

<xs:enumeration value="">
    <xs:annotation>
        <xs:documentation>Blank</xs:documentation> 
    </xs:annotation>
</xs:enumeration>

            }
        }
        throw new IllegalArgumentException(v);
    }

}
maxOccurs问题

对于maxOccurs问题，可以使用以下带有no verify（-nv）标志的命令行来解析XML架构：

xjc -nv -d out http://www.acf.hhs.gov/programs/cb/systems/nytd/nytd_data_file_format.xsd
这将使您克服以下错误，而无需修改XML架构：

xjc -nv -d out http://www.acf.hhs.gov/programs/cb/systems/nytd/nytd_data_file_format.xsd
正在分析架构。。。[错误]当前 解析器的配置不正确 允许使用maxOccurs属性值 设置为大于值5000。
第41行

XMLBeans也不会为此XML架构生成枚举。使用XMLBeans 2.5.0（最新版本），将为educationLevelType生成以下内容：
