这个是我的方法所在的模块的配置：

        classpath:mybatis-config.xml
    


    
          



    
    

这个是Biz层的配置：

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:p="http://www.springframework.org/schema/p" 
xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:context="http://www.springframework.org/schema/context" 
xsi:schemaLocation="

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-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/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 

 
 
 
 
 
 
 
 
 
 
 
 

这个是dao层的配置：

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:p="http://www.springframework.org/schema/p" 
xmlns:aop="http://www.springframework.org/schema/aop" 
xmlns:tx="http://www.springframework.org/schema/tx" 
xmlns:context="http://www.springframework.org/schema/context" 
xsi:schemaLocation="

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 

 
 
     
 

其他方法都没有问题。但是就是当调用多个接口的时候出现错误

出错方法如下：
@Component
public class EsbExcelHandler {

private static EsbExcelHandler excelHandler = new EsbExcelHandler();
private int flag = 0;//用于标识
@Autowired
private SoaCfgMessageControlMapper soaCfgMessageControlMapper;    
@Autowired
private SoaCfgMessageListMapper soaCfgMessageListMapper;
@Autowired
private SoaCfgServListMapper soaCfgServListMapper;
@Autowired
private SoaCfgMessageMetaDataMapper soaCfgMessageMetaDataMapper;
@Autowired
private SoaCfgMessageStructureMapper soaCfgMessageStructureMapper;

public int importMsgHeaderExcel(File file) {

    try {
        int res  = parseMsgHeaderExcel(file);
        if(res>0){
            flag = 1;
            return flag;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return flag;
}

public int parseMsgHeaderExcel(File importFile) throws Exception {
    //....解析文件代码省略
    // 报文头对象
    List listMsgCtrl = new ArrayList();
    // 报文字段表
    List listmetaData = new ArrayList();
    SoaCfgMessageControl msgCtrl = new SoaCfgMessageControl();
    SoaCfgMessageMetaData metaData = new SoaCfgMessageMetaData();
    //取出appsSysId
        for(int i = 0;i

            try{
                if(exampleMsgCtrl != null){
                    int ctrlRes =soaCfgMessageControlMapper.countByExample(exampleMsgCtrl);//出错。
                    System.out.println("一共有："+ctrlRes+"条记录");
            }
        }catch(Exception e){
            flag = 0;
            System.out.println("请检查数据库连接或者sql语句，导入操作失败！！！");
            e.printStackTrace();
        }
    }
        return flag;
}
