DdlGenerator constructor needs no arguments?

问题

I wanted to unit test my database operation and I found this code. However, I get the followin error:

[CityGame] $ test
[info] Compiling 2 Java sources to /Users/pmichna/Documents/code/citygame/target/scala-2.10/test-classes...
[error] /Users/pmichna/Documents/code/citygame/test/models/BaseModelTest.java:31: error: constructor DdlGenerator in class DdlGenerator cannot be applied to given types;
[error]         ddl = new DdlGenerator((SpiEbeanServer) server, new MySqlPlatform(), config);
[error]               ^
[error]   required: no arguments
[error]   found: SpiEbeanServer,MySqlPlatform,ServerConfig

[error] 1 error
[error] (test:compile) javac returned nonzero exit code
[error] Total time: 2 s, completed 2013-12-17 00:21:23

Has the implementation of DdlGenerator changed?

回答1:

Yes, the implementation has changed. The constructor takes no argument but instead there is a setup() method that should be used. This lead to something like this :

EbeanServer server = Ebean.getServer(serverName);
ServerConfig config = new ServerConfig();
DdlGenerator ddl = new DdlGenerator();
ddl.setup((SpiEbeanServer) server, new MySqlPlatform(), config);
