bug修正及删除功能实现
1、log4j-1.2.15版本bug,建议不要使用它，而建议使用log4j-1.2.14
2、对应${org.parent.name}，当org为顶级机构时候回报错空指针异常，修改
Organization.hbm.xml添加 not-found="ignore":
Organization.java添加not-found="ignore":
为
3、添加机构的唯一编号，修改OrgManagerImpl.java的addOrg(Organization org, int parentId)方法为：
public_del_success.jsp文件:
public_update_success.jsp文件:
update_add_succes.jsp文件
DelOrgAction.java文件
修改OrgManagerImpl.java的deleteOrg(int orgId)方法为：
为
修改struts.xml文件为：
启动tomcat，测试！
1、log4j-1.2.15版本bug,建议不要使用它，而建议使用log4j-1.2.14
引用
After upgrading from 1.2.14 to 1.2.15 the following error show up during
shutdown:
log4j:ERROR LogMananger.repositorySelector was null likely due to error in
class
reloading, using NOPLoggerRepository.
No errors at all with 1.2.14
This probably is related to bug 40212

2、对应${org.parent.name}，当org为顶级机构时候回报错空指针异常，修改
Organization.hbm.xml添加 not-found="ignore":
<many-to-one column="pid" access="field" name="parent" not-found="ignore"/>
Organization.java添加not-found="ignore":
/** * @hibernate.many-to-one * column="pid" not-found="ignore" */ private Organization parent;index.jsp修改
<td align="center" vAlign="center">
<c:out value="${org.parent.name}"></c:out>
</td>
为
<td align="center" vAlign="center">
<c:if test="${!empty org.parent.name}">
<c:out value="${org.parent.name}"></c:out>
</c:if>
</td>
3、添加机构的唯一编号，修改OrgManagerImpl.java的addOrg(Organization org, int parentId)方法为：
public void addOrg(Organization org, int parentId) {
if(parentId != 0)
org.setParent((Organization)getHibernateTemplate().load(Organization.class, parentId));
getHibernateTemplate().save(org);
//TODO 设置机构的唯一编号
org.setSn(org.getParent() == null ? "" + org.getId(): org.getParent().getId() + "_" + org.getId());
getHibernateTemplate().update(org);
}4、完成删除功能：

if(i > 0)
setTimeout("clock();",1000);

DelOrgAction.java文件
package com.oa.action;
import com.oa.manager.OrgManager;
import com.opensymphony.xwork2.ActionSupport;
public class DelOrgAction extends ActionSupport {
private OrgManager orgManager;
private int id;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public void setOrgManager(OrgManager orgManager) {
this.orgManager = orgManager;
}
@Override
public String execute() throws Exception {
orgManager.deleteOrg(id);
return "del_success";
}
}
修改OrgManagerImpl.java的deleteOrg(int orgId)方法为：
public void deleteOrg(int orgId) {
Organization org = (Organization) getHibernateTemplate().load(Organization.class, orgId);
if(org.getChildren().size() > 0)
throw new RuntimeException("有子机构存在，不允许删除！");
getHibernateTemplate().delete(getHibernateTemplate().load(Organization.class, orgId));
}修改index.jsp文件中
<a href="#" onclick="del('del.do?mentod=del&id=${org.id }');">删除</a></td>
为
<a href="#" onclick="del('del.action?id=${org.id }');">删除</a></td>
修改struts.xml文件为：
<package name="struts2" namespace="/" extends="struts-default">
<global-results>
<result name="add_success">/common/pub_add_success.jsp</result>
<result name="del_success">/common/pub_del_success.jsp</result>
<result name="update_success">/common/pub_update_success.jsp</result>
</global-results>
<action name="Login" class="loginAction">

<action name="org" class="orgAction">
<result name="success">/org/index.jsp</result>

<action name="add_input" class="orgAction" method="add">
<result name="success">/org/add_input.jsp</result>
</action>
<action name="add" class="addAction">
<result name="success">/common/pub_add_success.jsp</result>
</action>
<action name="del" class="delAction"></action>
</package>applicationContext-actions.xml文件中添加：
<bean id="addAction" class="com.oa.action.AddOrgAction">
<property name="orgManager" ref="orgManager"/>
</bean>
<bean id="delAction" class="com.oa.action.DelOrgAction">
<property name="orgManager" ref="orgManager"/>
</bean>
启动tomcat，测试！
