myBatis 字符串数字参数解析

背景   标志位  cJdgPzbz =='0' 时解析失败

思路

将所有字符串数字处理

转化 Double 后进行  === 运算  

导致 值相等  数据类型不相等  String === Double 

返回 false

 

// 来之百度
return s.length() == 0 ? 0.0D : Double.parseDouble(s);

正确答案

<if test="cJdgPzbz != null and cJdgPzbz != '' and cJdgPzbz =='0'.toString()">
	and o.N_JDGH is null
</if>
<if test="cJdgPzbz != null and cJdgPzbz != '' and cJdgPzbz =='1'.toString()">
	and o.N_JDGH is not null
</if>
