无法将XSD转换为Java类

Question

我的customer.xsd如下所示。我正试图将它转换为pojo类schema_reference.4:未能读取模式文档“xml.xsd”，因为

1）找不到文件；

2）文件无法阅读；

3）文档的根元素不是 。

我正在使用maven将XSD转换为Java clases。

                Elements of this type are import-only and will never be exported.  
                Furthermore, elements of this type will be handled only if included in
                a customer import file (customer.xsd) but are ignored if included in a 
                customer list import (customerlist2.xsd).
                <p/>
                The reason for this discrepancy is that customer groups are site-specific, 
                and customer import is always done in the context of a site whereas customer 
                list import is not.

            Import: If the attribute 'encrypted' is set to false, the content of this tag will be encrypted  
            using the new scrypt algorithm. 'encryptionScheme' should be 'null' in this case.
            If the attribute 'encrypted' is set to true, it is assumed that the given password was encrypted
            with the algorithm in 'encryptionScheme' (md5, scrypt, or the internal implementation s0001). 
            The password will be imported 'as is'.

            Export: The attribute 'encrypted' will always be set to true. The attribute 'encryptionScheme'
            will reflect the encryption scheme of the password in the database (md5 (deprecated), scrypt, or the internal implementation s0001). 
            The encrypted password will not be transformed during export.

                            When a &lt;group-assignment&gt; element is imported, the customer with the specified 
                            customer-no is assigned to the customer group with the specified group-id.  If an assignment 
                            already exists, no change is made.

                            When an element is imported with attribute mode="delete", the assignment of the customer
                            with the specified customer-no to the customer group with the specified group-id is removed.
                            If the customer is not assigned to the group, no change is made.

                            When mode="delete", either the customer-no or group-id attribute can be omitted to remove

                            Assignments can only be created or removed for static customer groups.  A warning message
                            is logged if a specified customer group is dynamic.

Answer 1

您所引用的xml.xsd的旧版本，因此请更新此。请从XSD中替换以下内容。

     <xsd:import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="xml.xsd" />

将上面替换为

     <xsd:import namespace="http://www.w3.org/XML/1998/namespace"  schemaLocation="http://www.w3.org/2001/xml.xsd"/>

如果您使用的是eclipse，请使用jaxb插件从XSD生成类。
