我目前正在尝试配置一个spring引导应用程序，以便为两个不同的数据源使用两个不同的坞容器(postgres图像)。为此，我从这是白龙教程获取代码并将其复制到一个新项目中。我在注释中调整了包结构，但仍然遇到错误。虽然我设法找到了其中一些解决方案，但我现在被困住了。当调用docker-compose up时，应用程序的启动会在两个postgres容器启动后使用IllegalStateException崩溃。

我希望有User ( sourceone )和Product ( sourcetwo )的表。现在，当我使用psql查看db容器时，我看到的是没有找到任何关系(我猜这是因为应用程序崩溃了，这就是我试图修复它的原因)。我的工作流程是运行./mvnw.exe clean install，然后用docker build -t test/multiple-db .构建一个码头映像，最后运行docker-compose up。

在试图修复其他错误的过程中，我添加并更改了一些依赖项。我读到这个错误可能也与依赖项的问题有关，但是到目前为止我还没有找到解决方案。下面是一些可能有用的代码片段，其中大部分与上面提到的教程(github源)非常相似。它似乎有些依赖是过时的，我试图修复，但也许我已经在这个过程中造成了更大的损害。

您正在将两个容器端口映射到主机的同一个5432。使用两个不同的端口，并在application.properties文件中包含已更改的端口。
