mybatis:Parameter 'list' not found. Available parameters are [templateId, param1, param2, valueList]
我的EsdTemplateSealMapper.java里面定义的接口是这样的
public List<EsdTemplateSeal> getFilteOutSeal(@Param("filterList")List<String> list,@Param("templateId")String templateId);
然后我的EsdTemplateSealMapper.xml里面的sql是这样的:
<select id="getFilteOutSeal" resultMap="BASE_RESULT_MAP"> select t.TEMPLATE_ID, t.SEAL_ID, t.SEAL_TYPE, t.DATA_SRC, t.VERSION from ESD_TEMPLATE_SEAL t where t.TEMPLATE_ID=#{templateId,jdbcType=VARCHAR} and t.SEAL_TYPE not in <foreach item="item" collection="list" separator="," open="(" close=")" index=""> #{0} </foreach> </select>
也写过这样的:
<select id="getFilteOutSeal" resultMap="BASE_RESULT_MAP"> select t.TEMPLATE_ID, t.SEAL_ID, t.SEAL_TYPE, t.DATA_SRC, t.VERSION from ESD_TEMPLATE_SEAL t where t.TEMPLATE_ID=#{templateId,jdbcType=VARCHAR} and t.SEAL_TYPE not in <foreach item="item" collection="list" separator="," open="(" close=")" index=""> #{filterList} </foreach> </select>
控制台都报类似:“
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.binding.BindingException: Parameter 'list' not found. Available parameters are [templateId, param1, param2, valueList]
”的问题,
最终的解决方案是:
<select id="getFilteOutSeal2" parameterType="map" resultMap="BASE_RESULT_MAP"> select t.TEMPLATE_ID, t.SEAL_ID, t.SEAL_TYPE, t.DATA_SRC, t.VERSION from ESD_TEMPLATE_SEAL t where t.TEMPLATE_ID=#{id} and t.SEAL_TYPE not in <foreach item="item" collection="filterList" separator="," open="(" close=")" index="index"> #{item} </foreach> </select>
ps:网上的解释实在坑爹,根本原因就是他们根本就没有理解foreach里面的collection应该放什么东西,错误的理解里面放的是java.util.List,其实这个类型应该是和我们的@Param绑定的参数名一致
