不会吧.再加个lazy="false" 试试

[xiajunsuc]

<hibernate-mapping>
<class table="t_orgnization" name="com.bjsxt.oa.model.Orgnization">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
<property name="sn"/>
<property name="description"/>

<many-to-one column="pid" name="parent" fetch="join" lazy="false"/>
<set lazy="false" inverse="true" name="children">
<key column="pid"/>
<one-to-many class="com.bjsxt.oa.model.Orgnization" />
</set>
</class>
</hibernate-mapping>

[xiajunsuc]

按照上面的配置也不行

no session 说明你的session已经关闭了.才导致了你的懒加载错误. 你是ssh一起用报的错还是怎么的?配置文件都贴出来啊. 光贴一个hibernate的配置文件能说明问题吗.

事物配置出了问题

[sl514]

事务配置

[xiajunsuc]

如何配置事务

[archko]

<many-to-one column="pid" name="parent" fetch="join" lazy="false"/>这样写后日志里记录的SQL是怎样的,有没有把Parent查出来呢?
没办法就加个过滤器,HibernateFilter,在一个Request里控制Session

[被人抢先注册了昵称的小泥鳅]

需要看你的ssh配置文件才能下结论

[izard999]

延迟加载的问题.. 把set中的lazy设成false

[xiajunsuc]

lazy 已经设置成false，配置如下：

<hibernate-mapping>
<class table="t_orgnization" name="com.bjsxt.oa.model.Orgnization">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
<property name="sn"/>
<property name="description"/>

<many-to-one column="pid" name="parent" />
<set lazy="false" inverse="true" name="children">
<key column="pid"/>
<one-to-many class="com.bjsxt.oa.model.Orgnization" />
</set>
</class>
</hibernate-mapping>

package com.bjsxt.oa.model;

import java.util.Set;

/**
*
* @author Administrator
* @hibernate.class table="T_Orgnization"
*/
public class Orgnization {

private int id;

private String name;

private String sn;
private String description;

private Orgnization parent;

private Set children;

private int parentId =0;

public int getParentId() {
return parentId;
}

public void setParentId(int parentId) {
this.parentId = parentId;
}

public Set getChildren() {
return children;
}
public void setChildren(Set children) {
this.children = children;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Orgnization getParent() {
return parent;
}
public void setParent(Orgnization parent) {
this.parent = parent;
}
public String getSn() {
return sn;
}
public void setSn(String sn) {
this.sn = sn;
}
}

if(parentId != 0){
Orgnization org = orgManager.findOrg(parentId);
Orgnization parent = org.getParent();（执行这句开始出错）
if(parent != null){
ppid = parent.getId();
}
}
equest.put("ppid", ppid);

[archko]

getParent你设置了False是Children的有什么用.
<many-to-one column="pid" name="parent" />加一个fetch="select或join"

[xiajunsuc]

<hibernate-mapping>
<class table="t_orgnization" name="com.bjsxt.oa.model.Orgnization">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
<property name="sn"/>
<property name="description"/>

<many-to-one column="pid" name="parent" fetch="join"/>
<set lazy="false" inverse="true" name="children">
<key column="pid"/>
<one-to-many class="com.bjsxt.oa.model.Orgnization" />
</set>
</class>
</hibernate-mapping>
好像也不行呀
