Question

我有时可以运行该程序。但是，由于找不到JpaRepository，因此一半时间无法完成构建。代码中没有抛出任何错误，并且pom中包含spring-boot-starter-data-jpa。

要解决此问题，我对pom.xml进行了少量更改，让项目重新执行依赖项，然后还原所做的更改并重新导入所有内容。然后，该项目将在再次“丢失” JpaRepository文件之前，可以进行1-5次重新启动。正如其他答案所建议的那样，我已经包括了h2工件，但无济于事。

POM：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.4.RELEASE</version>
</parent>

存储库界面：

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface QuoteRepository extends JpaRepository<Quote, Long> {

    List<Quote> findByValue(String value);
}

用法：

import package.persistence.repo.QuoteRepository;
import package.web.exception.QuoteIdMismatchException;
import package.web.exception.QuoteNotFoundException;
import org.json.JSONObject;
import org.json.JSONTokener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.*;

import javax.net.ssl.SSLContext;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;

@RestController
@RequestMapping("/api/quotes")
public class QuoteController {

    @Autowired
    private QuoteRepository quoteRepository;

    @Autowired
    public QuoteController(QuoteRepository quoteRepository){

        this.quoteRepository = quoteRepository;
        //LoadSeedData(10);
    }
}

java间歇性找到JpaRepository
