Question

我遇到了一个问题，我的事务由Spring Tx控制，当我进行合并和刷新后，我的实现不打印命令，而且Spring Tx也没有提交它们。

按照我的代码：

@Named
@Transactional(propagation = Propagation.MANDATORY, readOnly = false)
class AverbacaoDAOImpl extends AbstractDAOImpl<Averbacao, Long> implements AverbacaoDAO{

    private List<Averbacao> atualizarAverbacoes(final List<Averbacao> averbacoes, final EtapaAverbacao etapa) {

        int counter = 0;
        for(Averbacao averbacao : averbacoes) {
            averbacao.setEtapa(etapa);
            atualizar(averbacao);
            counter += 1; 
    }

        entityManager.flush();
        LOGGER.debug("Atualizado {} averbacoes para a etapa {}", counter, etapa);
        return averbacoes;
    }

}

private atualizar(Averbacao averbacao) {
    entityManager.merge(averbacao);
}

列表中的每个对象都由JPA管理（或者我认为它们是

经过多方努力，我发现我的团队从查询中返回的对象被提取为只读。

因此，我们在查询中得到提示READ_ONLY，现在可以更新对象

JPA没有合并，也没有冲洗我的实体
