spring.net实现访问数据库,对表增、删、改、查支持事务拦截

zazugpt 2024-09-02 04:29:50 编程文章 19 ℃ 0 评论

搜索了很多资料终于把spring.net 对oracle的操作实现（winform），并且事务的控制很好。在这里把源码贴出来，方便大家。

spring.net 版本为1.3.1

1：项目引用组件：

其中common.loggin.dll为必要的组件，因为spring.net的相关日志输入都是基于该组件

2：项目结构

实现简单的层级entity、dao、biz、impl、service

3：配置文件

//app.config 文件

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<configSections>

<sectionGroup name="spring">

<section name="context" type="Spring.Context.Support.ContextHandler,Spring.Core"/>

<section name="objects" type="Spring.Context.Support.DefaultSectionHandler,Spring.Core" />

<section name="parsers" type="Spring.Context.Support.NamespaceParsersSectionHandler, Spring.Core"/>

</sectionGroup>

</configSections>

<startup>

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />

</startup>

<!--Spring.Net节点配置-->

<spring>

<parsers>

<parser type="Spring.Data.Config.DatabaseNamespaceParser, Spring.Data"/>

<parser type="Spring.Transaction.Config.TxNamespaceParser, Spring.Data"/>

</parsers>


<context>

<!--容器配置-->

<resource uri="config://spring/objects"/>

<!--注入spring配置-->

<resource uri="~/config/Objects.xml"/>

</context>

<!--必要的-->

<objects xmlns="http://www.springframework.net"></objects>

</spring>

</configuration>

//Objects.xml 此文件和app.config文件配置的注入文件名称保持一致

<?xml version="1.0" encoding="utf-8" ?>

<objects xmlns="http://www.springframework.net"

xmlns:aop = "http://www.springframework.net/aop"

xmlns:db="http://www.springframework.net/database"

xmlns:tx="http://www.springframework.net/tx">

<!--spring.net的事务管理器 但是要用到spring.net自身dao实现-->

<!--<db:provider id="dbProvider"

provider="System.Data.SqlClient"

connectionString="server=数据库地址;database=LeHuoTest;user id=sa;password=Lh123$%^;Pooling=true;Min Pool Size=10;Max Pool Size=50;Connection Lifetime=30;Connection Timeout=30;"/>-->

<!--spring.net访问oracle的配置方法 -->

<db:provider id="dbProviderOracle"

provider="System.Data.OracleClient"

connectionString="Data Source=数据库地址/ORCL;User ID=cvnx2;Password=thinkpad#$#;"/>

<!-- 注入连接 -->

<object id="adoTemplate" type="Spring.Data.Core.AdoTemplate, Spring.Data">

<property name="DbProvider" ref="dbProviderOracle"/>

<property name="DataReaderWrapperType" value="Spring.Data.Support.NullMappingDataReader, Spring.Data"/>

</object>

<!--dao 注入-->

<object id="StudentDao" type="springAdoStudyDao.StudentDao,springAdoStudyDao">

<!--注入 AdoTemplate，名称必须为AdoTemplate，不能改变-->

<property name="AdoTemplate" ref="adoTemplate" />

</object>

<!--impl 注入-->

<object id="StudentImpl" type="springAdoBiz.StudentImpl,springAdoBiz">

<!--name属性为 StudentImpl的属性,必须和StudentImpl类下面的属性保持一致， ref为应用注入-->

<property name="StudentDao" ref="StudentDao"></property>

</object>

<!--service 注入-->

<object id="StudentService" type="springAdoStudyService.StudentService,springAdoStudyService">

<!--name属性为 StudentService的属性,必须和StudentService类下面的属性保持一致, ref为应用注入-->

<property name="StudentImpl" ref="StudentImpl"></property>

</object>


<!--事务管理器-->

<object id="transactionManager"

type="Spring.Data.Core.AdoPlatformTransactionManager, Spring.Data">

<property name="DbProvider" ref="dbProviderOracle"/>

</object>

<!--自定义驱动方式(根据方法的名字判断事务的类型——oracle)-->

<tx:advice id="txAdviceOracle" transaction-manager="transactionManager">

<tx:attributes>

<tx:method name="*" no-rollback-for="ErrorException" rollback-for="BussinessException" isolation="ReadCommitted" timeout="120" />

</tx:attributes>

</tx:advice>


<!--事务切面-->

<tx:attribute-driven/>

</objects>
