如何在ormlite中将两个字段作为一个主键？

Question

create table temp（id int，userId int，query text，createdOn text，primary key（id，userId））;

如何使用ormlite创建id和UserId作为一个主键？

@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当你使用generatedId = true;

时它是主键
