org.springframework.data.relational.repository.query.RelationalEntityInformation.getTableName()‘：'java.lang.String java.lang.NoSuchMethodError

Question

我正在使用下面的org.springframework.data.relational.repository.query.RelationalEntityInformation.getTableName()'“并获得"java.lang.NoSuchMethodError：'java.lang.String POM

有人能帮上忙吗。

Answer 1

您正在使用的spring-data-r2dbc版本与Spring Boot2.3.x默认使用的其他Spring Data模块的版本不兼容。

Spring Boot2.3具有依赖项管理和Spring Data R2DBC的starter模块，因此您可以通过使用starter并从pom中删除版本来对齐版本。

替换以下三个依赖项：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-r2dbc</artifactId>
    <version>1.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-spi</artifactId>
    <version>0.8.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-postgresql</artifactId>
    <version>0.8.0.RELEASE</version>
</dependency>

具有以下功能：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-r2dbc</artifactId>
</dependency>
<dependency>
    <groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-postgresql</artifactId>
    <scope>runtime</scope>
</dependency>

spring-data-r2dbc和r2dbc-spi依赖项都是替换它们的spring-boot-starter-data-r2dbc依赖项的一部分。版本由spring-boot-starter-parent中的依赖项管理提供。
