如何获取长类型键ibatis @InsertProvider

Question

@InsertProvider(type = UserSqlProvider.class, method = "insertSql")
@Options(useGeneratedKeys = true, keyProperty = "id", keyColumn = "GENERATED_KEY")
Long insert(Use user);

我使用ibatas @ InsertProvider，并希望获得long类型的primery键，但这种方法只是例外：

java.lang.Integer cannot be cast to java.lang.Long

怎么了？

Answer 1

我自己发现了，就像这样：

@InsertProvider(type = UserSqlProvider.class, method = "insertSql")
@Options(useGeneratedKeys = true, keyProperty = "id", keyColumn = "GENERATED_KEY")
void insert(Use user);

执行如下：

userMapper.insert(user);
System.out.print(user.getId());//use this get id
