這篇文章主要講解了“mybatis配置對(duì)象的方式”，文中的講解內(nèi)容簡(jiǎn)單清晰，易于學(xué)習(xí)與理解，下面請(qǐng)大家跟著小編的思路慢慢深入，一起來(lái)研究和學(xué)習(xí)“mybatis配置對(duì)象的方式”吧！

mybatis是一個(gè)非常好用且靈活的持久層框架，但也正是因?yàn)樘^(guò)靈活，導(dǎo)致有時(shí)候參數(shù)很難整理。我把我在項(xiàng)目中遇到的一個(gè)特殊情況列出來(lái)，希望下次再碰到時(shí)，也有個(gè)印象。
實(shí)體類(lèi)如下：

}

}

return rows;
}
public void setRows(Integer rows) {
this.rows = rows;
}
public String getStockName() {
return stockName;
}
public void setStockName(String stockName) {
this.stockName = stockName;
}
public String getSupplierName() {
return supplierName;
}
public void setSupplierName(String supplierName) {
this.supplierName = supplierName;
}
public List<Long> getCondSupplierIds() {

}
public void setCondSupplierIds(List<Long> condSupplierIds) {

}
public List<Integer> getCondStatuss() {

}
public void setCondStatuss(List<Integer> condStatuss) {

}這里的實(shí)體類(lèi)中，包含了一個(gè)List對(duì)象，所以在寫(xiě)xml文件的時(shí)候多少對(duì)我這種菜鳥(niǎo)有點(diǎn)難度。
<select id="selectPurchaseDeliverByPrimaryKeySelective" resultMap="purchaseResultMap">

</select>標(biāo)紅的地方，即為應(yīng)用。在foreach循環(huán)中，引用index作為list的下標(biāo)，這樣即可將對(duì)象中的所有數(shù)據(jù)取出。
