# SpringBoot 连接示例

更新时间：2026-05-16 19:39:20

本文介绍 SpringBoot 连接示例。

## 环境配置

JDK1.8 和 OceanBase 3.x（mysql模式/oracle模式）

## 示例代码

### Pom.xml 文件

```java

```

### application.yml 文件

```java
server:
  port: 8081
spring:
  jpa:
    database: oracle
    show-sql: true
  datasource:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://host:port/test?characterEncoding=UTF-8
      username: **u***
      password: ******
#spring.jpa.hibernate.ddl-auto=update
jackson:
  serialization:
    indent_output: true

```

### 测试类

相关代码如下：

```java
package com.alipay;

import javax.persistence.*;
import java.io.Serializable;
import java.sql.Date;

/*
* CREATE TABLE A(id integer, flightNo varchar2(50))
*
*/
@Entity
@Table( name = "A" )
public class A implements Serializable {
    public Integer getFlightId() {
        return flightId;
    }

    public void setFlightId(Integer flightId) {
        this.flightId = flightId;
    }

    public String getFlightNo() {
        return flightNo;
    }

    public void setFlightNo(String flightNo) {
        this.flightNo = flightNo;
    }

    @Id
//    @GeneratedValue
// oracle 没有自增策略，添加该注解可以自动生成一个序列，提供自增主键，若数据库已有相关序列，可以忽 //略该注解。
    @Column(name = "id")
    private Integer flightId;

    @Column( name = "flightNo" )
    private String flightNo;

}

```

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface AMapper extends JpaRepository<A, Integer> {

}

```

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

import java.util.Optional;

@RestController
@RequestMapping("/")
public class Test {
    @Autowired
    private AMapper a;
    @GetMapping("/{id}")
    public String getOne(@PathVariable int id) {

        Optional<A> obj = a.findById(id);
        String result = "A.id is:" + obj.get().getFlightId() + ", no is :" + obj.get().getFlightNo();
        System.out.println(result);
        return result;
    }
}

```

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

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

```

运行上面的代码，如下日志表示启动成功。

然后通过 `http://localhost:8081/xxxxx` 就可以访问数据库， `xxxxx` 就是对应的数据库 `id` 字段，如果数据库存在就可以查询到结果。
