本想着从前端传入一个Long类型的id来查询一个列表,结果报了这个错,在网上看到了两种方法,用的第一种解决的
第一种:用"_parameter"代替当前参数
<select id="selectSubjectByPId" parameterType="java.lang.Integer" resultType="java.util.Map"> select subjectId,subjectName from ts_subject where subjectParentId= 0 <if test="_parameter != null"> and subjectId = #{_parameter,jdbcType=INTEGER} </if> </select>
第二种:解决方案很简单,在java代码中使用@Param 标签指定传入参数名称即可;
public String queryMethodName(@Param(value="varName") Long varName);
