import org.springframework.context.annotation.Bean;

@Entity
//@Table(name = "userlogindetails")

I can see lots of errors. 我可以看到很多错误。 As you requested suggested ways of debugging, here it goes. 如您所要求的建议调试方式，就可以了。

  1. Clean up your pom.xml. 清理您的pom.xml。 It's very dirty and hard to understand. 这很脏而且很难理解。 As you are using spring-boot and spring boot jpa remove following dependencies for now. 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>

Also a dependency is added twice:- 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>

Remove it. 去掉它。

You could later once applications runs could use these dependencies as per your need. 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. I would recommend using release version of springboot for now. 我建议暂时使用springboot的发行版。 Hence change 2.0.0.M3 to 2.0.0.M3 in parent spring boot dependency. 因此，将父级Spring Boot依赖项中的2.0.0.M3更改为2.0.0.M3。

  2. Fix your application.properties file as it has lots of problems. 修复您的application.properties文件，因为它有很多问题。 Below is a updated one:- 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

Please try following and then see what exception you get and try to troubleshoot from there. 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。
