在非字符串注释字段 spring 中使用 yml 文件中的值

Question

I want to use configuration value in annotation field, field is not string. For example i have:

@Document(indexName = "#{@transactionIndexName}", shards = 1, 
refreshInterval = "2s", versionType = VersionType.EXTERNAL)

So in indexName i used spring spel, but shards is short type value, so how can i use here setting from yml file?

Answer 1

You should be able to convert your shards value from a String to a short within a Spel expression with something like this:

#{T(java.lang.Short).parseShort(${transaction.shards})}

... assuming that your property is transaction.shards of course.

I'm not able to test this at the moment, but I believe that should work.
