我正在尝试使用以下凭据通过 Flyway 连接到 Oracle 数据库

spring.jpa.database=oracle
spring.datasource.url=jdbc:oracle:thin:@172.17.0.2:32773/ORCLPDB1
spring.datasource.username=sys
spring.datasource.password=Oradoc_db1

但我收到以下错误

谁能指出我在这里遗漏了什么？以及如何解决这个问题。

Answer 1

首先你需要检查容器暴露的正确端口是否为 1521/tcp 端口：

docker port your_containerID 1521/tcp

然后确保容器中的数据库已启动： docker ps (* 在容器状态不健康时检查)

1.- 连接sqlplus

docker exec -it your_containerID bash -c "source /home/oracle/.bashrc; sqlplus /nolog"

2.- 使用例如 SQL Developer IDE 连接 jdbc 并创建一个方案：

create user "MYUSER" identified by  admin123 default tablespace "USERS" temporary tablespace "TEMP";
grant "DBA" to "MYUSER";
grant "RESOURCE" to "MYUSER";

grant SELECT ANY DICTIONARY to "MYUSER";
grant CREATE SEQUENCE to "MYUSER";
grant CREATE SYNONYM to "MYUSER";
grant CREATE SESSION to "MYUSER";
grant CREATE TYPE to "MYUSER";
grant CREATE PROCEDURE to "MYUSER";
grant CREATE DATABASE LINK to "MYUSER";
grant CREATE ANY DIRECTORY to "MYUSER";
grant CREATE TABLE to "MYUSER";
grant EXPORT FULL DATABASE to "MYUSER";
grant UNLIMITED TABLESPACE to "MYUSER";
grant CREATE JOB to "MYUSER";
grant CREATE VIEW to "MYUSER";
grant ALTER SESSION to "MYUSER";

grant EXECUTE on "SYS"."SYS_PLSQL_FAA5F685_2385_1" to "MYUSER";
grant EXECUTE on "SYS"."SYS_PLSQL_D9B1149D_9_1" to "MYUSER";

最后一步在你的 application.yml 中：

datasource:
    username: MYUSER
    password: admin123
    driver-class-name: oracle.jdbc.OracleDriver
    url: jdbc:oracle:thin:@(description=(address=(host=your_docker_ip)(protocol=tcp)(port=your_port_number))(connect_data=(service_name=ORCLPDB1.localdomain)))
