Spring 3.1 事务配置

Spring 3.1 事务配置

 

spring发的包最好用的是2.5.6；所依赖的包全部都有，可是后来的版本都缺这少那的，导致开发中遇到各种各样的问题。

 

下面主要讲述如何给你的spring应用加上事务:

 

1、准备依赖的包

 

org.springframework.aop-3.1.0.RELEASE.jar                                            
org.springframework.asm-3.1.0.RELEASE.jar                                            
org.springframework.aspects-3.1.0.RELEASE.jar                                    
org.springframework.beans-3.1.0.RELEASE.jar                                        
org.springframework.context-3.1.0.RELEASE.jar                                    
org.springframework.context.support-3.1.0.RELEASE.jar                    
org.springframework.core-3.1.0.RELEASE.jar                                        
org.springframework.expression-3.1.0.RELEASE.jar                            
org.springframework.jdbc-3.1.0.RELEASE.jar                                        
org.springframework.orm-3.1.0.RELEASE.jar                                            
org.springframework.transaction-3.1.0.RELEASE.jar                            
org.springframework.web-3.1.0.RELEASE.jar                                            
org.springframework.web.struts-3.1.0.RELEASE.jar

 

-- spring 2.5.6中获取
aopalliance.jar                                                                                                
aspectjweaver.jar    
-- MySQL驱动
mysql-connector-java-5.1.17-bin.jar    
-- 必须的包
commons-dbcp-1.4.jar    
commons-lang-2.6.jar                                                                                    
commons-logging-1.1.1.jar                                                                            
commons-pool-1.6.jar        
log4j-1.2.16.jar

 

 

2、配置

 

引入xml头文件

<?xml version="1.0" encoding="GBK"?>
<beans xmlns="http://www.springframework.org/schema/beans"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xmlns:aop="http://www.springframework.org/schema/aop"
             xmlns:tx="http://www.springframework.org/schema/tx"
             xsi:schemaLocation="
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/tx
         http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

 

引入配置文件

        <!-- 不加密时候使用 -->
        <!--<context:property-placeholder location="classpath:jdbc.properties,classpath:tdmc.properties"/>-->

        <!-- 加密时候使用 -->
        <bean id="propertyConfig" class="com.lavasoft.freamwork.ext.spring.PropertyPlaceholderConfigurerExt">
                <property name="locations">
                        <list>
                                <value>classpath:jdbc.properties</value>
                                <value>classpath:tdmc.properties</value>
                        </list>
                </property>
        </bean>

 

配置事务:

        <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
                <property name="dataSource" ref="dataSource"/>
        </bean>
        <tx:advice id="txAdvice" transaction-manager="txManager">
                <tx:attributes>
                        <tx:method name="get*" read-only="true"/>
                        <tx:method name="set*" read-only="true"/>
                        <tx:method name="query*" read-only="true"/>
                        <tx:method name="find*" read-only="true"/>
                        <tx:method name="load*" read-only="true"/>
                        <tx:method name="count*" read-only="true"/>
                        <tx:method name="save*" rollback-for="Exception"/>
                        <tx:method name="update*" rollback-for="Exception"/>
                        <tx:method name="delete*" rollback-for="Exception"/>
                        <tx:method name="merage*" rollback-for="Exception"/>
                </tx:attributes>
        </tx:advice>
        <aop:config>
                <aop:pointcut id="serviceOperation"
                                            expression="execution(* com.asiainfo.tdmc.service.*SV.*(..))"/>
                <aop:advisor advice-ref="txAdvice"
                                         pointcut-ref="serviceOperation"/>
        </aop:config>

 

 

3、测试

 

设置MySQL的表为InnoDB类型，在保存中抛出异常，和不抛出异常做比较，看看能否保存，即可知道事务是否起作用。

 

        public Test_dept saveTest_dept(Test_dept test_dept) {
                test_dept =    test_deptDAO.insert(test_dept);
                if(true) throw new RuntimeException();
                return test_dept;
        }

 

发现数据库没有保存上。

 

去掉事务配置的xml片段，则保存进去了。
