異常如下：org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error evaluating expression 'requestMap.maintenancename != null and requestMap.maintenancename != '''. Cause: org.apache.ibatis.ognl.OgnlException: source is null for getProperty(null, "maintenancename")

解決方案：在dao層添加dao層方法中加@Param("requestmap")注解即可
