Spring+Mybatis框架

mapper.xml中用到了<where><if>標簽判斷，出現了上述錯誤

<select id = "getOrderByCompany" resultType="com.chinamobile.sias.workorder.po.Workorder">
        select * from t_view_workorder
        <where>
            <if test="company != '全國'">
                wo_company = #{company}
            </if>
        </where>
</select>

mapper.java中代碼如下

List<Workorder> getOrderByCompany(String company);

解決方法

在參數前加@Param標簽

List<Workorder> getOrderByCompany(@Param("company")String company);

OK！
