Caused by: org.apache.ibatis.ognl.OgnlException: source is null for getProperty(null, mil

今天在使用mybatis处理数据库的时候，突然抛出了上述异常，让我感到很惊讶，因为在处理save的时候，在Mybatis的配置文件中，我根本就没有使用到ognl表达式，系统怎么会抛出上述异常。而且之前也是这么使用的，也没见抛出上述异常。然后查看操作数据库的Mybatis的配置文件，倒是找到了几个错误，但是都不是引起这个异常的原因。然后，再仔细查看这个配置文件，突然之间，发现了，在该配置文件：

<!-- save -->
<insert id="save">insert into qa_sampling(s_id , s_mil_id , s_samplingPackage , s_samplingWeight , s_samplingPerson_id , s_samplingCardFill , s_samplingDate , s_createTime)values(#{s_id} , ${s_mil.mil_id} , #{s_samplingPackage} , #{s_samplingWeight} , #{s_samplingPerson.u_id} , #{s_samplingCardFill} , #{s_samplingDate} , #{s_createTime})
</insert>

${s_mil.mil_id} , 这一处，居然是使用$，难怪系统将其作为表达式进行解析，将其修改成”#”之后，一切OK，上述异常成功解决。现，贴出正确的写法：

<!-- save -->
<insert id="save">insert into qa_sampling(s_id , s_mil_id , s_samplingPackage , s_samplingWeight , s_samplingPerson_id , s_samplingCardFill , s_samplingDate , s_createTime)values(#{s_id} , #{s_mil.mil_id} , #{s_samplingPackage} , #{s_samplingWeight} , #{s_samplingPerson.u_id} , #{s_samplingCardFill} , #{s_samplingDate} , #{s_createTime})
</insert>
