Question

我正在尝试将我的STS项目与DB连接。

但我无法导入@EnableJpaRepositories。

我的代码AccountRepository.java：

package com.myongjoon.spring;

import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
@Configuration
@EnableJpaRepositories(basePackages="com.myongjoon.spring")
public interface AccountRepository extends JpaRepository<Account, Long> {
}

和pom.xml：

我认为我依赖于EnableJpaRepositories spring-data-jaa

但此代码有红线

import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
@Configuration
@EnableJpaRepositories(basePackages="com.myongjoon.spring")

我需要其他依赖吗？

Answer 1

我希望项目根目录或pom旁边还有一个红色感叹号。因为你已经两次添加了spring数据jpa依赖!!!

 <dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.2.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-commons-core</artifactId>
    <version>1.4.0.RELEASE</version>
</dependency>
...
<dependency>
   <groupId>org.springframework.data</groupId>
   <artifactId>spring-data-jpa</artifactId>
   <version>1.0.0.RELEASE</version>
</dependency>

另一个问题可能是您在版本1.2中明确使用spring-data-commons-core，但spring-data-jpa 1.2仍然使用spring-data-commons版本1.0

因为你仍然使用Spring 3.2，我建议使用Spring Data Release Train＆＃34; Dijkstra＆＃34;：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-releasetrain</artifactId>
            <version>Dijkstra-SR5</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
...
<dependencies>
    ...
    <dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-jpa</artifactId>
            <!-- version defined by spring-data-releasetrain bom-->
        </dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-commons-core</artifactId>
            <!-- version defined by spring-data-releasetrain bom-->
        </dependency>
    <dependency>
</dependencies>

或者您更新到更新的Spring Version 4.2.x

@EnableJpaRepositories依赖项
