最早是
configuration.configure();

这行出错，说找不到.java文件，把文件粘过去后报错说
org.dom4j.DocumentException: Error on line 1 of document : Content is not allowed in prolog. Nested exception: Content is not allowed in prolog.

java 代码 ：
package biz.entity;

import java.io.Serializable;

public class User implements Serializable{

private static final long serialVersionUID = 1L;
private int id;
private String name;
private int age;
private String habbis;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getHabbis() {
return habbis;
}
public void setHabbis(String habbis) {
this.habbis = habbis;
}
public User() {
super();
// TODO Auto-generated constructor stub
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
User.hmb.xml:

网友回复:问题搞定了，原来是我把cfg.xml的mapping resource写错了
