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

<!-- 具体不知道出问题加上此据不出问题了 -->
<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-entitymanager</artifactId>
  <version>5.0.3.Final</version>
</dependency>

<!-- oracle 数据库-->
  <dependency>
      <groupId>com.oracle</groupId>
      <artifactId>ojdbc6</artifactId>
      <version>11.2.0.1.0</version>
  </dependency>
<!--Spring-data-jpa依赖-->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

<dependency>

<groupId>net.sourceforge.nekohtml</groupId>

<artifactId>nekohtml</artifactId>

<version>1.9.22</version>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-thymeleaf</artifactId>

</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：

package com.gao.Controller;

import com.gao.Inf.GaoRepository;
import com.gao.entity.Gam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.List;


/*@ComponentScan(basePackages = "com.gao.*")
@EnableJpaRepositories(basePackages = "com.gao.*")
@EntityScan(basePackages = "com.gao.*")*/
@RestController
public class configController {
    @Resource
    private GaoRepository  gaoRepository;
    public GaoRepository getGaoRepository() {
        return gaoRepository;
    }

    public void setGaoRepository(GaoRepository gaoRepository) {
        this.gaoRepository = gaoRepository;
    }


    @RequestMapping(value = "/Gam")
    public List<Gam> 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")*/
public class Gam implements Serializable {
    @Id
    @GeneratedValue
    private int id;
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Gam{" +
                "id=" + id +
                ", name='" + name + '\'' +
                '}';
    }
}

接口：

package com.gao.Inf;

import com.gao.entity.Gam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository
public interface GaoRepository extends JpaRepository<Gam, Integer> {
    @Override
    List<Gam> findAll();
}

启动类：

package com.gao;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableAutoConfiguration
@SpringBootApplication
/*@ComponentScan(basePackages = "com.gao.*")
@EnableJpaRepositories(basePackages = "com.gao.*")
@EntityScan(basePackages = "com.gao.*")*/
public class RunApp {
    public static void main(String[] args) {
        SpringApplication.run(RunApp.class, args);
    }
}
