Spring boot 带MyBatis的Spring数据JDBC未找到自定义查询

我试图将Spring数据JDBC与MyBatis结合使用。我对使用Crudepository提供的现成CRUD方法以及编写MyBatis XML文件中定义的其他自定义查询感兴趣

从阅读其中的说明来看，我所需要做的似乎就是创建一个实现我想要的方法的

Mapper

（遵循规则“语句的名称是通过将实体类型的完全限定名与Mapper连接而构造的”）并将方法签名添加到我的

crudepository

。我已经这样做了，但Spring数据似乎从未找到我的方法，并给出以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'fooApplication': Invocation of init method failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: No query specified on findByChangeOwnerId; nested exception is java.lang.IllegalStateException: No query specified on findByChangeOwnerId

我也遵循了来自的例子，但是对于我来说没有太多的东西可以继续下去

问题是:

我可以在Crudepository中添加额外的方法来调用MyBatis吗？如果是的话，你能解释我在下面遗漏了什么吗

我假设对于任何附加方法，我都可以传入我想要的任何参数，而不是总是必须传入

MyBatisContext

我的积垢

package com.xxx.repository.jdbc;

import com.xxx.model.Foo;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;

import java.util.List;

public interface FooBmtRepository extends CrudRepository<Foo, String> {  
  List<Foo> findByChangeOwnerId(@Param("id") String id);
}

映射器XML

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.xxx.model.ItsmMapper">
    <!--<select id="findByChangeOwnerId" resultType="com.xxx.model.Itsm" parameterType="org.springframework.data.jdbc.mybatis.MyBatisContext">-->
    <!--where change_owner_id=#{changeOwnerId}-->
    <select id="findByChangeOwnerId" resultMap="itsmResultMap" parameterType="String">
        select *
        from [myschema].[tbl_itsms_bmt]
        where change_owner_id=#{id}
    </select>

    <resultMap id="itsmResultMap" type="com.xxx.model.Itsm">
        <result property="changeNumber" column="change_number"/>
        <result property="itsmUrl" column="itsm_url"/>
        <result property="changeTitle" column="change_title"/>
        <result property="category" column="category"/>
        <result property="status" column="status"/>
        <result property="createdDate" column="created_date"/>
    </resultMap>

</mapper>

链接到的部分的开头为：

对于

crudepository

中的每个操作，Spring数据JDBC都会运行多个语句。如果应用程序上下文中有一个

SqlSessionFactory

，Spring数据会检查每个步骤SessionFactory是否提供语句。如果找到一个，则使用该语句（包括其到实体的配置映射）

这仅适用于

crudepository

中的方法。 其他方法不是这样工作的

您可以实现一个完整的自定义方法实现，调用MyBatis

或者，您也可以为MyBatis支持的命名查询创建一个问题，甚至可能创建一个PR。

我已经阅读了您所注意到的内容，但不确定我是否正确解释了该声明-感谢您的澄清。现在我已经打开了一个增强请求。谢谢如果您知道如何改进文档以使其更清晰，我也将不胜感激。
