记一次springboot+jpa+链接oracle的实例以及遇到的问题

解释IDEA mark directory as的作用 蓝色时代表文件可以编辑可以创建文件 黄色时候代表运行时不加载此文件 

 一，maven配置 jpa和oracle驱动

  org.hibernate
  hibernate-entitymanager
  5.0.3.Final

  
      com.oracle
      ojdbc6
      11.2.0.1.0
  


  org.springframework.boot
  spring-boot-starter-data-jpa

      <dependency>

          <groupId>net.sourceforge.nekohtmlgroupId>

          <artifactId>nekohtmlartifactId>

          <version>1.9.22version>

      dependency>

       

      <dependency>

          <groupId>org.springframework.bootgroupId>

          <artifactId>spring-boot-starter-thymeleafartifactId>

dependency>

创建application.application文件在目录 src/main/resoures  resoures 文件夹设置成蓝色 右键此文件夹 mark directory as 设置成socures boot

控制层：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;

    }


    @RequestMapping(value = "/Gam")
    public List findAll() {
        return gaoRepository.findAll();

}

实体类：

package com.gao.entity;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import java.io.Serializable;
@Entity
/*@Table(name = "gaohaiming")*/
