java - org.springframework.beans.factory.UnsatisfiedDependencyException : Error creating bean with name.无法让我的springboot应用程序运行

Question

我是微服务新手，并开始使用简单的 Get 和 Post 实现构建一个微服务。我收到有关 bean 创建和不满足的依赖异常的错误。请找到我所附的代码。任何帮助表示赞赏。提前致谢。

DbServiceApplication.java(在com.example.dbservice包下)

package com.example.dbservice;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@EnableJpaRepositories(basePackages = "com.example.dbservice.repository")
@SpringBootApplication
public class DbServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(DbServiceApplication.class, args);
    }
}

QuotesRepository.java(位于 com.example.dbservice.repository 包下)

package com.example.dbservice.repository;

import com.example.dbservice.model.Quote;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;

import java.util.List;

@Repository
public interface QuotesRepositpory extends JpaRepository<Quote, Integer> {
    List<Quote> findByUserName(String username);
}

DbServiceResource(在存储库 com.example.dbservice.resource 下)

package com.example.dbservice.resource;


import com.example.dbservice.model.Quote;
import com.example.dbservice.model.Quotes;
import com.example.dbservice.repository.QuotesRepositpory;
import org.springframework.web.bind.annotation.*;

import java.util.List;
import java.util.stream.Collectors;

@RestController
@RequestMapping("/rest/db")
public class DbServiceResource {

    private QuotesRepositpory quotesRepository;

    public DbServiceResource(QuotesRepositpory quotesRepository) {
        this.quotesRepository = quotesRepository;
    }

    @GetMapping("/{username}")
    public List<String> getQuotes(@PathVariable("username")
                                  final String username){

        return quotesRepository.findByUserName(username)
                .stream()
                .map(Quote::getQuote)
                .collect(Collectors.toList());

    }


    @PostMapping("/add")
    public List<String> add(@RequestBody final Quotes quotes){
        return null;
    }

}

Answer 1

在 spring 配置中，您已在“com.techprimers.stock.dbservice.repository”中声明了 jpa 存储库的基础包
@EnableJpaRepositories(basePackages = "com.techprimers.stock.dbservice.repository")

但是从存储库代码来看，实际上它位于包“com.example.dbservice.repository”内

因此更改配置中的基础包，例如:

@EnableJpaRepositories(basePackages = "com.example.dbservice.repository")
@SpringBootApplication
public class DbServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(DbServiceApplication.class, args);
    }
}

更新:现在错误是由于缺少 jaxb 组件，java.xml.bind 是 java 的一部分，直到 jdk 8 为止，并且从 9 开始已弃用。在 pom.xml 中添加以下内容

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
