如何將兩個字段作爲ormlite中的一個主鍵？

Question

create table temp（id int，userId int，查詢文本，createdOn文本，主鍵（id，userId））;

如何使用ormlite創建id和UserId作爲一個主鍵？

@DatabaseField(columnName = "_id",id = true,generatedId = true) 
private long _id; 
@DatabaseField(columnName = "userId") 
private String userId; 
@DatabaseField(columnName = "query") 
public String query; 
@DatabaseField(columnName = "createdOn") 
public String createdOn; 

Answer 1

@DatabaseField(columnName = "_id",id = true,generatedId = true) 
private long _id; 

_id它是當你使用generatedId =真主鍵;
