我正在尝试使用Spring和AspectJ实现加载时间编织.据我所知,我已经正确配置了所有内容,但是当我尝试运行集成测试时,我不断收到错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.weaving.AspectJWeavingEnabler#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [sun.misc.Launcher$AppClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method.

我在下面有以下承诺链,它看起来很混乱(每个_create*函数返回一个承诺):

return new Promise(function (resolve, reject) {
      _this.database.transaction(function (t) {
        _this._createExternalAccount(payment, t)
          .then(function (externalAccount) {
            return _this._createExternalTransaction(externalAccount, payment, t)
              .then(function (externalTransaction) {
                return _this._createAddress(externalAccount, payment, t)
                  .then(function (address) {
                    return _this._createTransaction(address, payment, t)
                      .then(function (transaction) {
                        return _this._createGatewayTransaction(externalTransaction, transaction, payment, t)
                          .then(function (gatewayTransaction) {
                            t.commit();
                            resolve(bridgePayment);
                          });
                      });
                  });
              });
          })
          .error(function (bridgePayment) {
            t.rollback();
            reject(bridgePayment);
          });
      });

我知道我可以使用Promise函数all(),join()但这些似乎同时运行我无法执行的函数,因为持久化到某些表需要来自先前持久化表的字段.我希望有一些方法让我做以下的事情,但我似乎无法找出如何:

Promise.all(_this._createExternalAccount(payment, t), _this._createExternalTransaction(externalAccount, payment, t), _this._createAddress(externalAccount, payment, t))
    .then(function(externalAccount, externalTransaction, address) {
        // do logic …
