在我的 Spring Boot 项目中，当我@Query在 CrudRepository 中添加方法时出现以下错误

java.lang.IllegalStateException: You have defined query method in the repository but you don't have any query lookup strategy defined. The infrastructure apparently does not support query methods!

使用的库：

  • Spring Data Commons - 2.0.7.RELEASE
  • Spring Data JDBC - 1.0.0.M3
  • Spring Boot - 2.0.3.RELEASE

=== 更新代码

这是存储库文件

package org.docsy.app.account;

import java.util.List;

import org.springframework.data.jdbc.repository.query.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;

interface TeamRepository extends CrudRepository<Team, Long>{

  @Query("Select * from account where teamId = :teamId")
  List<Account> getTeamAccounts(@Param("teamId") Long teamId);

}

我在这里遵循示例：https ://github.com/spring-projects/spring-data-examples/blob/master/jdbc/basics/src/main/java/example/springdata/jdbc/basics/aggregate/ LegoSetRepository.java

==== 使用堆栈跟踪更新

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'teamRepository': Invocation of init method failed; nested exception is java.lang.IllegalStateException: You have defined query method in the repository but you don't have any query lookup strategy defined. The infrastructure apparently does not support query methods!

这看起来像DATAJDBC-228

几乎引用（带有通用版本信息）：

问题的根本原因是 Spring Boot 的当前 GA 版本将 Spring Data Commons 的版本指定为 2.0.x 但是 Spring Data JDBC 的版本需要 2.1.x，当 Boot不存在时，它也会被 Maven 自动拉入。

要解决此问题，只需向您的 pom 添加显式依赖项：

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-commons</artifactId>
  <version>2.1.x</version>
</dependency>

您可能还想查看这篇关于如何使用 Spring Boot 控制依赖关系版本的文章：https ://spring.io/blog/2016/04/13/overriding-dependency-versions-with-spring-boot

尝试将 Spring Data JDBC 更新到最新版本

<!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-jdbc-core -->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jdbc-core</artifactId>
    <version>1.2.1.RELEASE</version>
</dependency>
