将 postgresql 数据库添加到 travis

Question

这是我第一次使用任何 CI。我用过特拉维斯。在当前提交中，我添加了postgresql，但使用stacktrace 构建失败（在我的计算机（本地）上它工作正常）：（整个stacktrace https://travis-ci.org/must1/BookstoreScraper/builds/568424005?utm_source=github_status&utm_medium=notification）

org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

我知道它找不到 postgres，但我不知道如何添加它。

travis.yml配置：

language: java

addons:
  sonarcloud:
    organization: "must1"
    token:
      secure: TOKEN # encrypted value of your token

script:
  # the following command line builds the project, runs the tests with coverage and then execute the SonarCloud analysis
  - mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent install sonar:sonar

application.properties

spring.datasource.url=jdbc:postgresql://localhost:5432/bookstore_scraper
spring.datasource.username=postgres
spring.datasource.password=1234
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults= false

Travis 文档中有一整章介绍了如何设置数据库。

特别是：

https://docs.travis-ci.com/user/database-setup/#postgresql

基本上你将 Postgres 添加到服务中：

services:
  - postgresql

并创建一个数据库：

before_script:
  - psql -c 'create database travis_ci_test;' -U postgres

如果您需要特定版本的 Postgresql：

https://docs.travis-ci.com/user/database-setup/#using-a-different-postgresql-version

如果您需要 Postgresql 11 - 还有一些工作要做（2019-08-07）：

Java 的最小示例 .travis.yml：

dist: xenial
sudo: required
language: java

before_script:
  - psql -c 'create database travis_ci_test' -U postgres

before_install:
  - sudo apt-get update
  - sudo apt-get --yes remove postgresql\*
  - sudo apt-get install -y postgresql-11 postgresql-client-11
  - sudo cp /etc/postgresql/{9.6,11}/main/pg_hba.conf
  - sudo service postgresql restart 11

env:
  global:
    - PGUSER=postgres
    - PGPORT=5432

script:
  - psql -c "SELECT version();" 

上面的例子可以修改为其他语言 - 比如language: node_js
