这个是我的方法所在的模块的配置：<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" {代码...} </beans>这个是Bi

把你的配置po上来，理论上你单个接口可以正常调用，多个也不会报错 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.XXXXXXX.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> 加上这个再试下

Mapper接口你使用bean注解了吗，比如@Service 或者 @Component ? 看了下你贴出的配置，没有找到你spring 扫描包的配置，可以加上这个试试 <context:component-scan base-package="com.ibs.clearing"/>

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：

@Autowired
private SoaCfgMessageControlMapper soaCfgMessageControlMapper;

        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<SoaCfgMessageControl> listMsgCtrl = new ArrayList<SoaCfgMessageControl>();
    // 报文字段表
    List<SoaCfgMessageMetaData> listmetaData = new ArrayList<SoaCfgMessageMetaData>();
    SoaCfgMessageControl msgCtrl = new SoaCfgMessageControl();
    SoaCfgMessageMetaData metaData = new SoaCfgMessageMetaData();
    //取出appsSysId
        for(int i = 0;i<listMsgCtrl.size();i++){
            String appsSysId = listMsgCtrl.get(i).getAppsSysId();// 获得主键 应用系统代码
            //通过appsSysId查询是否有 记录
            SoaCfgMessageControlExample exampleMsgCtrl = new SoaCfgMessageControlExample();
            SoaCfgMessageMetaDataExample exampleMetaData = new SoaCfgMessageMetaDataExample();
            //查询Control表中的记录

exampleMsgCtrl.createCriteria().andAppsSysIdEqualTo(appsSysId);

            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;
}
