spring-boot - 带有 MyBatis 的 Spring Data JDBC 找不到自定义查询

问题描述

我正在尝试将 Spring Data JDBC 与 MyBatis 一起使用。我对使用 CrudRepository 提供的开箱即用的 CRUD 方法以及编写在 MyBatis XML 文件中定义的附加自定义查询感兴趣。

从阅读jdbc.mybatis的说明，听起来我需要做的就是创建一个Mapper实现我想要的方法的方法（遵守规则“语句的名称是通过连接实体类型的完全限定名称来构造的使用 Mapper ") 并将方法签名添加到我的CrudRepository. 我已经这样做了，但是 Spring Data 似乎从来没有找到我的方法并给出了这个错误：

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mybatis-spring-boot-sample中的示例，但我没有太多可以继续了解其中的内容。

问题是：

我可以向 CrudRepository 添加额外的方法来调用 MyBatis 吗？如果是这样可以解释我在下面缺少什么？
我假设对于任何其他方法，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 Crud 存储库

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);
}

src/main/resources/application.yml

mybatis:
  mapper-locations: classpath:/mapper/**/*.xml
  configuration:
    map-underscore-to-camel-case: true

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>

依赖项（大多数是使用启动器导入的，因为我无法mvn dependency:tree正确显示，所以显示所有内容）
