添加maven依赖项会在我的spring批处理期间出现特定错误

Question

我正在批处理,我遇到了一个问题.我已经确定了我的问题的原因,但我无法解决它.

一旦我在我的pom中添加依赖项,我就会开始出错

maven依赖是

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

我的pom如下所示

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

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

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

我得到的错误是这个

Answer 1

从给定的堆栈跟踪中你可以看到找不到某些类,因为你使用的是spring引导,spring引用使用包含多个依赖项的meta依赖项,如spring-boot-cookbook中所述

Spring Boot旨在简化应用程序创建入门的过程.Spring Boot启动器是引导库,包含启动特定功能所需的所有相关传递依赖项的集合

spring-data-jpa是不够的,还有一些你需要的依赖,使用 spring-boot-starter-data-jpa

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
