【问题描述】：
是否有人碰巧知道使用多种方法（入站）重用服务激活器以及输出通道是否有效，尤其是使用拆分器和聚合器。
--> 始终在网关上显示结果。
在几个测试中，它似乎工作正常。一旦我添加了一个带有聚合器的拆分器，我就会将错误结果路由到网关，然后网关失败并出现转换异常（在我的情况下，它无法将布尔值转换为整数）。
谢谢，
保罗

单元测试
@Test
public void sendMessageNoReceiver() {
assertFalse(gateway.sendToBulb(new HomeId("1"), new BulbId("1"), BulbMessageBuilder.restart("foo")));
}
@Test
public void sendMessageWithReceiver() {
MockSession<BulbId, BulbBE> bulbSession = new MockSession<BulbId, BulbBE>(new BulbBE(HomeId.of("1"), BulbId.of("1"), "bulb", "pass"));
registry.addBulbSession(bulbSession);
assertTrue(gateway.sendToBulb(new HomeId("1"), new BulbId("1"), BulbMessageBuilder.restart("foo")));
assertEquals(1, bulbSession.receivedMessages());
}
@Test
public void updateBulbStatus() {
final MockSession<BulbId, BulbBE> bulbSession1 = new MockSession<BulbId, BulbBE>(new BulbBE(HomeId.of("1"), BulbId.of("1"), "bulb", "pass"));
assertFalse(gateway.updateLightStatus(bulbSession1.getIdentity()));
registry.addBulbSession(bulbSession1);
assertTrue(gateway.updateLightStatus(bulbSession1.getIdentity()));
assertEquals(1, bulbSession1.receivedMessages());
final MockSession<BulbId, BulbBE> bulbSession2 = new MockSession<BulbId, BulbBE>(new BulbBE(HomeId.of("1"), BulbId.of("2"), "bulb", "pass"));
assertFalse(gateway.updateLightStatus(bulbSession2.getIdentity()));
registry.addBulbSession(bulbSession2);
assertTrue(gateway.updateLightStatus(bulbSession2.getIdentity()));
assertTrue(gateway.updateLightStatus(bulbSession2.getIdentity()));
assertEquals(2, bulbSession2.receivedMessages());
assertEquals(1, bulbSession1.receivedMessages());
}
@Test
public void updateHomeBulbStatus() {
final HomeBE home = new HomeBE();
home.setId(new ObjectId());
final MockSession<BulbId, BulbBE> bulbSession1 = new MockSession<BulbId, BulbBE>(new BulbBE(home.getStrongId(), BulbId.of("1"), "bulb", "pass"));
registry.addBulbSession(bulbSession1);
final MockSession<BulbId, BulbBE> bulbSession2 = new MockSession<BulbId, BulbBE>(new BulbBE(home.getStrongId(), BulbId.of("2"), "bulb", "pass"));
registry.addBulbSession(bulbSession2);
home.addBulb(bulbSession1.getIdentity());
assertEquals(1, gateway.updateHomeLightStatus(home));
assertEquals(1, bulbSession1.receivedMessages());
assertEquals(0, bulbSession2.receivedMessages());
home.addBulb(bulbSession2.getIdentity());
assertEquals(2, gateway.updateHomeLightStatus(home));
assertEquals(2, bulbSession1.receivedMessages());
assertEquals(1, bulbSession2.receivedMessages());
}
如果最后一个测试与其他测试一起执行，则它会失败。如果单独执行，则通过。
错误是最后一个方法（使用拆分器）现在接收一个布尔值，这似乎是其他两个方法注册的结果。这些方法的结果是一个布尔值。
【问题讨论】：
-
- BooleanAggregator 计算真值 - BulbTransformer 将转换为服务在激活器中期望的类型 * 方法：sendToBulb 按原样发送消息 * 方法：updateLightStatus 发送消息但只转换一次 * 方法: updateHomeLightStatus 现在发送一个集合，该集合是使用拆分器表达式 payload.bulbs 提取的给定参数的一部分
