Description:

Field userLoginRepo in ca.naijaconnects.naijaconnectsproject.controller.NaijaConnectsController required a bean of type 'ca.naijaconnects.naijaconnectsproject.repo.UserLoginRepo' that could not be found.


Action:

Consider defining a bean of type 'ca.naijaconnects.naijaconnectsproject.repo.UserLoginRepo' in your configuration.

    @SuppressWarnings("unchecked")
    @RequestMapping(value = "/insertLogins", method = RequestMethod.POST)
    public @ResponseBody List<UserLoginDetails> PostFormDataJSONArray() {   
        UserLoginDetails userLoginDetail = new UserLoginDetails();
        userLoginDetail.setUserName("timisenco");
        userLoginDetail.setUserPassword("Test@2017");
        return (List<UserLoginDetails>) userLoginRepo.save(userLoginDetail);
    }

}

这是我的实体： 

package ca.naijaconnects.naijaconnectsproject.entity;
import java.io.Serializable;

import javax.persistence.*;

import org.springframework.context.annotation.Bean;

@Entity
//@Table(name = "userlogindetails")
public class UserLoginDetails 
{
    @Id
    @Column(name = "USER_NAME", nullable = false,columnDefinition="varchar2(40)")
    private String userName;

    @Column(name = "USER_Pawword", nullable = false,columnDefinition="varchar2(40)")
    private String userPassword;


    public UserLoginDetails()
    {

    }
    @Bean
    public String getUserName()
    {
        return userName;
    }
    @Bean
    public void setUserName(String userName)
    {
        this.userName = userName;
    }
    @Bean
    public String getUserPassword()
    {
        return userPassword;
    }
    @Bean
    public void setUserPassword(String userPasword)
    {
        this.userPassword = userPassword;
    }
}

这是回购： 

package ca.naijaconnects.naijaconnectsproject.repo;

import java.util.List;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.repository.*;
import org.springframework.stereotype.Repository;

import ca.naijaconnects.naijaconnectsproject.entity.UserLoginDetails;

@org.springframework.data.rest.core.annotation.RepositoryRestResource(exported=false)
public interface UserLoginRepo extends JpaRepository<UserLoginDetails, String>
{

    //UserLoginDetails findOne(String);
    @SuppressWarnings("unchecked")
    UserLoginDetails save(UserLoginDetails account);
    //UserLoginDetails findByEmailAddress(EmailAddress emailAddress);
}

我的应用程序属性： 

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost/naijaconnectsdb
spring.datasource.username=naijaConnects
spring.datasource.password=Connects@2017
spring.datasource.name=naijaconnectsdb
spring.jpa.hibernate.ddl-auto=update //fixed it after comments
spring.jpa.generate-ddl=true
spring.jpa.show-sql=true
spring.data.jpa.repositories.enabled=true
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect

我可以看到很多错误。 如您所要求的建议调试方式，就可以了。

  1. 清理您的pom.xml。 这很脏而且很难理解。 当您使用spring-boot和spring boot jpa时，暂时删除以下依赖项。 

     <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> </dependency> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-rest-core</artifactId> </dependency>

一个依赖项也被添加了两次： 

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

去掉它。

您可以稍后在应用程序运行后根据需要使用这些依赖项。

  1. 我建议暂时使用springboot的发行版。 因此，将父级Spring Boot依赖项中的2.0.0.M3更改为2.0.0.M3。

  2. 修复您的application.properties文件，因为它有很多问题。 以下是更新的：- 

     spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/naijaconnectsdb spring.datasource.username=naijaConnects spring.datasource.password=Connects@2017 spring.jpa.hibernate.ddl-auto=update //fixed it after comments spring.jpa.generate-ddl=true spring.jpa.show-sql=true spring.data.jpa.repositories.enabled=true spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

请尝试遵循，然后查看遇到什么异常，然后尝试从那里进行故障排除。
