Ibatis问题总结

1、有关parameterMap的使用

例子

sqlmap.xml中的配置（此处用的参数是HashMap类型）如下：

 

xml 代码

 

<select id="selectBySexExceptSelf" parameterMap="forSexParam" resultMap="productResult">

        select
        id,
        proname,
        pronum,
        proclick,
        probul,
        profee,
        prosex,
        procontent,
        procolor,
        prochic,
        prochicsm,
        promot,
        propic,
        prochange,
        proback,
        prouptime,
        proispush,
        proisnew,
        proison,
        prophoto,
        protoptime,
        proisremove,
        proremovetime,
        promodifytime,
        proisdis,
        prodisfee,
        proType
        from product
        <dynamic prepend="WHERE">
            <isParameterPresent prepend="and">
                id != #id#
            isParameterPresent>
            <isParameterPresent prepend="and">
                prosex = #prosex#
            isParameterPresent>
        dynamic>
select>

         
 

 

 

java调用代码：

java 代码

public List  getProductListBySexExceptSelf(Integer id,String sex) {
    HashMap hmParam = new HashMap();
    hmParam.put("id", id);
    hmParam.put("prosex", sex);
    return getSqlMapClientTemplate().queryForList(Product.class.getName() + ".selectBySexExceptSelf", hmParam);
}

请不要被很多网页中的问号的形式误导，这种写法将直接报错：The error occurred while applying a parameter map. 

<dynamic prepend="WHERE">
    <isParameterPresent prepend="and">
        id != ?
    isParameterPresent>
    <isParameterPresent prepend="and">
        prosex = ?
    isParameterPresent>
dynamic>
