一：发现问题

sql动态语句中如果 parameterType="int"

<select id="sel_campusinfo" parameterType="int" resultType="Campusinfo">
select cmpid,cmpname from campusinfo where state!='d' and cmpid=#{cmpid}
</select>

是正确的，但是如果加上if test

<select id="sel_campusinfo" parameterType="int" resultType="Campusinfo">
            select cmpid,cmpname from campusinfo where state!='d' and cmpid!=0
            <if test="cmpid!=0">and cmpid=#{cmpid}</if>
     </select>

则报错：

There is no getter for property named 'cmpid' in 'class java.lang.Integer'

出错原因：Mybatis默认采用ONGL解析参数，所以会自动采用对象树的形式取Integer.cmpid。Integer对象没有cmpid属性。如果不解析参数，mybatis自动识别传入的参数，不会报错。

二：解决办法
1.修改select语句

<select id="sel_campusinfo" parameterType="int" resultType="Campusinfo">
            select cmpid,cmpname from campusinfo where state!='d' and cmpid!=0
            <if test="_parameter!=0">and cmpid=#{_parameter}</if>
        </select>

参数名全部改为_parameter。

2.不修改sql，只修改接口

接口类：

Campusinfo sel_campusinfo( int cmpid);

改为：

Campusinfo sel_campusinfo(@Param(value="cmpid") int cmpid);

3.可以将参数包装在hashmap或者对象中作为参数
