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。
