MyBaties 提示org.apache.ibatis.builder.BuilderException: The expression ‘’**' evaluated to a null val

MyBaties 提示的错误信息：org.apache.ibatis.builder.BuilderException: The expression '***' evaluated to a null value.

错误的原因：SQL 参数为List 集合，传递的指定参数不是集合

解决的办法:MyBatis mapper 配置文件添加一层针对错误属性的集合判断：

<if test="***!= null and ***.size > 0"> 
		    	<foreach collection="***" item="sts" separator="," open="(" close=")"> 
		    		and (  
		    			(INSTR(TEST.ARCH_TITLE, $sts$) > 0) 
		    			OR (INSTR(TEST.MAKE_ORG_NAME, $sts$) > 0) 
		    			OR (INSTR(TEST.UNIT_PROJ_NAME, $sts$) > 0) 
		    		) 
		    	</foreach> 
		    </if>
