spring2.5+hibernate3.2+struts2.0插入数据时调用两次sql语句

Posted 2023-05-17

我使用Myeclipse自动生成的函数，getHibernateTemplate().save（），执行结果如下，每次都插入两条一样的数据 ，求高手指点下啊！
Hibernate: select flower0_.flo_id as flo1_3_0_, flower0_.flo_name as flo2_3_0_, flower0_.image as image3_0_, flower0_.price as price3_0_, flower0_.describes as describes3_0_, flower0_.store as store3_0_, flower0_.commend as commend3_0_, flower0_.object as object3_0_, flower0_.material as material3_0_, flower0_.uses as uses3_0_, flower0_.festival as festival3_0_, flower0_.click as click3_0_ from flower.dbo.flower flower0_ where flower0_.flo_id=?

Hibernate: select orderitem_.orderitem_id, orderitem_.order_id as order2_2_, orderitem_.flo_id as flo3_2_, orderitem_.quantity as quantity2_, orderitem_.order_date as order5_2_ from flower.dbo.orderitem orderitem_ where orderitem_.orderitem_id=?
Hibernate: insert into flower.dbo.customer (cus_name, password, tel, email, qq, address, cus_id) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into flower.dbo.orderitem (order_id, flo_id, quantity, order_date, orderitem_id) values (?, ?, ?, ?, ?)
Hibernate: insert into flower.dbo.orders (cus_id, totalprice, pay_money, pay_way, deliver_way, require_deliver_time, fact_deliver_time, deliver_case, receive_peo_name, receive_address, bless_world, receive_tel, order_peo_name, order_peo_tel, isanonymity, order_peo_email, order_id) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: select orderitem0_.orderitem_id as orderitem1_2_0_, orderitem0_.order_id as order2_2_0_, orderitem0_.flo_id as flo3_2_0_, orderitem0_.quantity as quantity2_0_, orderitem0_.order_date as order5_2_0_ from flower.dbo.orderitem orderitem0_ where orderitem0_.orderitem_id=?
Hibernate: update flower.dbo.orderitem set order_id=?, flo_id=?, quantity=?, order_date= where orderitem_id=

ssh经常出现这种状况，基本上都是前台提交了2次请求造成的，仔细看看前台是否 调用过javascript之类的去提交，很容易出现这个问题 参考技术A 你贴是代码并不是执行两次的关键代码，所以无法判断，你最好仔细检查一下写的代码

Spring + Hibernate + Spring Security 配置

【中文标题】Spring + Hibernate + Spring Security 配置

【英文标题】：Spring + Hibernate + Spring Security configs

【发布时间】：2012-01-23 22:18:12

【问题描述】：

我有一个应用程序，它使用 Spring、Hibernate 和 Spring Security。我的目标是为这些框架中的每一个提供一个配置 (.xml) 文件并且只加载一次。所以基本上我想要spring-config.xml、hibernate-config.xml、spring-security.xml 和web.xml 作为配置文件。它现在可以按我的意愿工作，但是当我查看部署日志时，显然有重复的条目 - 加载了不止一次的 bean。

web.xml - http://pastebin.com/7ELvV8fS

spring-config.xml - http://pastebin.com/FVTcNu7L

hibernate-config.xml - http://pastebin.com/xXWbgAex

spring-security.xml - http://pastebin.com/JUycGUNA

GlassFish 3.1 部署输出 - http://pastebin.com/53Bgyj2r

正如您在输出中看到的，spring-config.xml 很少被启动。我在spring-config.xml 中的自定义 bean 也被启动了两次。

【问题讨论】：

检查您的服务器配置，您是否将 2 个应用程序加载到容器中？

服务器配置一切正常。我已经做到了这一点：如果我从 spring-security 配置中删除 ，则不再有重复项，但是 spring-security 不知何故不起作用 - 说凭据不好。

【参考方案1】：

发生这种情况是因为您正在通过

在 Spring-security 中再次加载 spring-config

    <beans:import resource="/hibernate-config.xml"/>
    <beans:import resource="/spring-config.xml"/>

您可以尝试删除此 .通过以下配置，您无需为 spring-security 指定单独的上下文参数。

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring/spring-security.xml,
        classpath:spring/spring-config.xml
    </param-value>       
</context-param>
