InvalidMappingException提示Could not parse mapping document错误的解决方法

org.hibernate.InvalidMappingException: Could not parse mapping document from resource …(错误的xml文件)

出现这样的错误一般是映射文件中映射出错了，找到错误提示resource 后面提示的xml文件，对应POJO对象逐个检查，看是否遗漏了某些属性的配置，或者写错了。

举个例子：

package com.exam.entity;
import java.util.Set;
public class SubjectChapter {
private int chapterId;
private String chapterName;
private Subject subject;
private int chapterNum;
private Set question;
public int getChapterId() {
return chapterId;
}
public void setChapterId(int chapterId) {
this.chapterId = chapterId;
}
public String getChapterName() {
return chapterName;
}
public void setChapterName(String chapterName) {
this.chapterName = chapterName;
}
public Subject getSubject() {
return subject;
}
public void setSubject(Subject subject) {
this.subject = subject;
}
public int getChapterNum() {
return chapterNum;
}
public void setChapterNum(int chapterNum) {
this.chapterNum = chapterNum;
}
public Set getQuestion() {
return question;
}
public void setQuestion(Set question) {
this.question = question;
}
}

</class>

这里原本少写了chapterNum的映射，导致该错误的出现。
