javax.persistence.TransactionRequiredException: Executing an update/delete query

[mattshma]

执行更新的代码如下：

@Transactional
public void saveUser(User user) {
    log.debug("Request to save user : {}", user);
    String insertStr = "insert into my_user " +
        " (name, age) " +
        " values (?1, ?2)";
    em.createNativeQuery(insertStr)
        .setParameter(1, ra.getDepartment())
        .setParameter(2, ra.getHiveUser())
        .executeUpdate();
}

报错如下：

Exception in xxxImpl.saveUser() with cause = 'NULL' and exception = 'Executing an update/delete query'

javax.persistence.TransactionRequiredException: Executing an update/delete query
	at org.hibernate.query.internal.AbstractProducedQuery.executeUpdate(AbstractProducedQuery.java:1496)

修改如下即可：

@Transactional
public void saveUser(User user) {
    log.debug("Request to save user : {}", user);
    em.getTransaction().begin();
    String insertStr = "insert into my_user " +
        " (name, age) " +
        " values (?1, ?2)";
    em.createNativeQuery(insertStr)
        .setParameter(1, ra.getDepartment())
        .setParameter(2, ra.getHiveUser())
        .executeUpdate();
    em.getTransaction().commit();
}
