Example 1 with User

use of org.jpwh.model.fetching.interception.User in project microservices by pwillhan.

the class LazyInterception method storeTestData.

public FetchTestData storeTestData() throws Exception {
    UserTransaction tx = TM.getUserTransaction();
    tx.begin();
    EntityManager em = JPA.createEntityManager();
    Long[] itemIds = new Long[3];
    Long[] userIds = new Long[3];
    User johndoe = new User("johndoe");
    em.persist(johndoe);
    userIds[0] = johndoe.getId();
    User janeroe = new User("janeroe");
    em.persist(janeroe);
    userIds[1] = janeroe.getId();
    User robertdoe = new User("robertdoe");
    em.persist(robertdoe);

    Item item = new Item("Item One", CalendarUtil.TOMORROW.getTime(), johndoe, "Some description.");

    itemIds[2] = item.getId();
    tx.commit();
    em.close();
    FetchTestData testData = new FetchTestData();
    testData.items = new TestData(itemIds);
    testData.users = new TestData(userIds);
    return testData;
}

Example 2 with User

use of org.jpwh.model.fetching.interception.User in project microservices by pwillhan.

the class LazyInterception method noUserProxy.

@Test
