1.最重要的spring配置文件

service中方法：  
  
\[html\] view plain copy  
在CODE上查看代码片派生到我的代码片  
  
    public String insertEntity(BaseEntity entity) throws Exception \{    
            if (null == entity.getId() || "".equalsIgnoreCase(entity.getId())) \{    
                entity.setId(CreateUuid.getID());    
            \}    
            this.dao.insertEntity(entity);    
            int i=1/0;//测试spring事务    
            return entity.getId();    
        \}    
  
  
注意事项：  
  
//1.直接<aop:pointcut  
/\*expression="execution(public \* com.test.service.\*.\*(..))"  
id="pointcut" />  
达不到事务的目的，必须  
<aop:pointcut  
expression="execution(public \* com.ssm.core.frame.service.impl.\*.\*(..))"  
id="pointcut1" />  
才可以，如果在子类ProviderServiceImpl中的方法可以使用上面第一句话来进行事务控制。一遍情况下子类为空，用的都是继承的BaseService中方法，只切面子类ProviderServiceImpl是不行的。

测试代码：  
  
\[html\] view plain copy  
在CODE上查看代码片派生到我的代码片  
  
    Provider provider4 = new Provider();    
            //ProviderID,BH,MC,LXR,DH,DZ,YX,CZ,BZ1,BZ2    
            //provider4.setId(CreateUuid.getID());    
            provider4.setBh("bh4");    
            provider4.setMc("mc4");    
            provider4.setLxr("lxr4");    
            provider4.setDh("dh4");    
            provider4.setDz("dz4");    
            provider4.setYx("yx4");    
            provider4.setCz("cz4");    
            provider4.setBz1("bz1");    
            provider4.setBz2("bz2");    
            String insertResult4 = providerService.insertEntity(provider4);    
  
  
正确输出日志为：

注意日志中的有关事务的描述。  
  
假如事务没起作用，比如pointcut指向的类不对，那么日志信息为：

注意日志信息中的Closing non transactional SqlSession ，表明这个是没有事务控制的，因此可以成功插入记录，而没有进行回滚
