java - 解析 XML 时出错 : XML InputStream(13) need whitespace between attributes

Question

我是 Hibernate 新手。我的 Hibernate 项目中有一个异常(exception)，我认为这是由于我的 Lecteurs.hbm.xml 文件造成的。

我需要你的帮助。 谢谢。

异常情况如下:

958 [main] ERROR org.hibernate.util.XMLHelper - Error parsing XML: XML InputStream(13) need whitespace between attributes

下面是映射文件 Lecteurs.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

 <hibernate-mapping >
      <class name="bean.Lecteurs" table="LECTEURS">
          <id name="id" type="int" column="ID" >
            <generator class="increment"/>           
          </id>

          <property name="nom_lecteur" type="string" column="nomLecteur" />
          <property name="prenom_lecteur"" type="string" column="prenomLecteur" />
          <property name="date_naissance" type="Date" column="dateNaissance" />
          <property name="email_lecteur" column="emailLecteur" ></property>
        <property name="telephone" column="telephoneLecteur" ></property>
        <property name="adresse" column="adresseLecteur" ></property>

    </class>
</hibernate-mapping>

Answer 1

此行中连续有两个双引号，这可能会导致该错误:

<property name="prenom_lecteur"" type="string" column="prenomLecteur" />
