为嵌入式 h2 数据库设置端口号

Question

我仅将h2 内存数据库用于测试目的。默认端口似乎是8082，这导致我在heroku 上的测试失败。

我想更改此端口号。我怎样才能做到这一点 ？

到目前为止我做了什么：

1. 我的本​​地计算机 ($USER_HOME/.h2.server.properties) 上似乎有一个文件指定了此端口。更不用说在应用程序工作区之外拥有该文件很奇怪，我无法在heroku中检查它。

2. 我尝试在application-test.properties 中设置webPort、port（这是我用于测试的属性文件）但它不起作用（我尝试了不同的组合server.port、`spring .data.source.h2.webPort 等）

application-test.properties

spring.datasource.url=jdbc:h2:mem:tesdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

Answer 1

我找到了解决方案。早些时候，我为我的测试创建了一个基类，并在其中创建了我的 H2 服务器。端口设置在同一类中。

@BeforeClass
public static void init() throws SQLException {
    webServer = Server.createWebServer("-web", "-webAllowOthers", "-webPort", "8082");
    webServer.start();
}

但是更改端口并不能解决问题。我发现，与 eclipse 分别运行每个测试的方式相反，heroku 将所有测试都运行一次，因此服务器不会被破坏并且在两个测试之间保持活动状态。因此，我必须在每个测试类完成运行后终止服务器：

@AfterClass
public static void tearDown() throws SQLException {
    webServer.stop();
}
