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。
