出于某种原因,Hibernate 在我的课程中没有看到 Getter,或者至少我认为这是正在发生的事情。我在休眠映射文件或不同的 XML 配置文件中是否设置了错误?
我向您展示的代码是由 WaveMaker 生成的,应该可以工作。我正在尝试运行一个简单的 HQL 查询,但我总是收到以下错误。不管查询有多简单或查询的是什么实体,我总是会收到“找不到吸气剂”错误。
我将 WaveMaker 6.5 与它在安装期间下载的任何版本的 Hibernate 和 Spring 一起使用。
这是我得到的错误:
Run query error: Error creating bean with name 'm2mex2DBDataService' defined in
resource loaded through SAX InputSource: Cannot resolve reference to bean
'm2mex2DBHibernateTemplate' while setting constructor argument; nested exception is
org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'm2mex2DBHibernateTemplate' defined in resource loaded through SAX InputSource: Cannot
resolve reference to bean 'm2mex2DBSessionFactory' while setting bean property

'm2mex2DBSessionFactory' defined in resource loaded through SAX InputSource: Invocation
of init method failed; nested exception is org.hibernate.PropertyNotFoundException:
Could not find a getter for bookauthors in class com.m2mex2db.data.Author
这是我的 Author 类的代码:
package com.m2mex2db.data;
import java.util.HashSet;
import java.util.Set;
/**
* m2mex2DB.Author
* 05/08/2013 16:33:50
*
*/
public class Author {
private Integer id;
private String firstname;
private String lastname;
private Set<com.m2mex2db.data.Bookauthor> bookauthors = new HashSet<com.m2mex2db.data.Bookauthor>();
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public Set<com.m2mex2db.data.Bookauthor> getBookauthors() {
return bookauthors;
}
public void setBookauthors(Set<com.m2mex2db.data.Bookauthor> bookauthors) {
this.bookauthors = bookauthors;
}
}
这是我的休眠映射文件:
