Spring R2DBC Repos 自动配置未解析依赖项

Question

我有以下存储库：https://github.com/vlio20/bfit 我在其中尝试使用 R2DBC 以异步方式执行数据库操作。我遵循了以下教程（但可能已经过时 https://www.youtube.com/watch?v=DvO4zLVDkMs

以下是我的 pom 的相关依赖项：

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-r2dbc</artifactId>
  <version>1.4.2</version>
</dependency>

<dependency>
  <groupId>com.github.jasync-sql</groupId>
  <artifactId>jasync-r2dbc-mysql</artifactId>
  <version>2.0.6</version>
</dependency>

我使用的是默认配置，所以我的属性yaml中只有以下配置：

server:
  port: 2121

spring:
  profiles:
    active: ${env:default}

  r2dbc:
    url: r2dbc:mysql://localhost:3306/bf_db
    username: root
    password: root

app:
  name: Bfit

这是我得到的错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController' defined in file [/Users/vioffe/personal/bfit/api/target/classes/com/bfit/api/user/controller/UserController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userService' defined in file [/Users/vioffe/personal/bfit/api/target/classes/com/bfit/api/user/service/UserService.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepo' defined in com.bfit.api.user.db.UserRepo defined in @EnableR2dbcRepositories declared on R2dbcRepositoriesAutoConfigureRegistrar.EnableR2dbcRepositoriesConfiguration: Cannot resolve reference to bean 'r2dbcEntityTemplate' while setting bean property 'entityOperations'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'r2dbcEntityTemplate' defined in class path resource [org/springframework/boot/autoconfigure/data/r2dbc/R2dbcDataAutoConfiguration.class]: Unsatisfied dependency expressed through method 'r2dbcEntityTemplate' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'r2dbcConverter' defined in class path resource [org/springframework/boot/autoconfigure/data/r2dbc/R2dbcDataAutoConfiguration.class]: Unsatisfied dependency expressed through method 'r2dbcConverter' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'r2dbcMappingContext' defined in class path resource [org/springframework/boot/autoconfigure/data/r2dbc/R2dbcDataAutoConfiguration.class]: Unsatisfied dependency expressed through method 'r2dbcMappingContext' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'r2dbcCustomConversions' defined in class path resource [org/springframework/boot/autoconfigure/data/r2dbc/R2dbcDataAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.r2dbc.convert.R2dbcCustomConversions]: Factory method 'r2dbcCustomConversions' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/data/convert/JodaTimeConverters

Answer 1

如错误信息：

 java.lang.NoClassDefFoundError: org/springframework/data/convert/JodaTimeConverters

提到，您错过了 spring-data-commons 罐子。添加为依赖，错误应该解决

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