基础表是这样创建的：

CREATE TABLE abcd.logins

login_id bigint,
user_name text COLLATE "default".pg_catalog,
password_salt text COLLATE "default".pg_catalog,
password_hash text COLLATE "default".pg_catalog,
related_user_id bigint
)

CREATE TABLE abcd.users
(
user_id bigint,
first_name text COLLATE "default".pg_catalog,
last_name text COLLATE "default".pg_catalog,
user_name text COLLATE "default".pg_catalog
)

abcd.用户

CREATE TABLE abcd.logins
(
login_id bigint,
user_name text COLLATE "default".pg_catalog,
password_salt text COLLATE "default".pg_catalog,
password_hash text COLLATE "default".pg_catalog,
related_user_id bigint
)

CREATE TABLE abcd.users
(
user_id bigint,
first_name text COLLATE "default".pg_catalog,
last_name text COLLATE "default".pg_catalog,
user_name text COLLATE "default".pg_catalog
)

我无法找出数据未持久化到数据库中的原因。我甚至调用了存储库的

flush（）

方法，但都没有用。有人能帮我吗？

如果使用@Transaction执行junit测试，请参见，但默认情况下，框架将为每个测试创建并回滚一个事务

如果您希望提交一个事务—这是不寻常的，但在您希望某个特定测试填充或修改数据库时偶尔有用—可以通过@TransactionConfiguration和@Rollback注释指示TestContext框架使事务提交，而不是回滚

您使用@Transaction执行junit测试，请参见，但默认情况下，框架将为每个测试创建并回滚一个事务

如果不想回滚事务，可以为特定测试添加@Rollback（false）。在您的情况下，我希望您已经使用

commit

方法提交了事务

就你而言：

@Test
@Rollback(false)
public void saveOne2One(){
    Logins lgn = new Logins();
    lgn.setUserName("userName");
    lgn.setPasswordHash("dfaskjdfaksjfdalksdf");

    Users usr = new Users();
    usr.setFirstName("test");
    usr.setLastName("last");
    usr.setUserName("userName");

    usr.setLogins(lgn);
    lgn.setUsers(usr);
    loginsRepository.save(lgn);
    //usersRepository.save(usr);
    loginsRepository.flush();
}

或者，如果希望在不回滚的情况下为所有测试（类级别）保留数据，则可以使用：

@TransactionConfiguration（defaultRollback=false）

如果不想回滚事务，可以为特定测试添加@Rollback（false）。在您的情况下，我希望您已经使用

commit

public void saveOne2One(){

    lgn.setUserName("userName");

    Users usr = new Users();
    usr.setFirstName("test");
    usr.setLastName("last");
    usr.setUserName("userName");

    usr.setLogins(lgn);
    lgn.setUsers(usr);
    loginsRepository.save(lgn);
    //usersRepository.save(usr);
    loginsRepository.flush();
}
