136.3. multimap cache producer - to("hazelcast-multimap:foo")

136.3. multimap cache producer - to("hazelcast-multimap:foo")

多映射是一个缓存，您可以将 n 值存储为一个键。多图生成者提供 4 个操作(put、get、delete 值、delete)。

请求消息的标头变量：

Expand

名称	类型	描述
`CamelHazelcastOperationType`	`字符串`	有效值为： put, get, removevalue, delete from Camel 2.16: clear。
`CamelHazelcastObjectId`	`字符串`	在缓存中存储 / 的对象 id

136.3.1. 放置的示例：

Java DSL：

from("direct:put")
.setHeader(HazelcastConstants.OPERATION, constant(HazelcastOperation.PUT))
.to(String.format("hazelcast-%sbar", HazelcastConstants.MULTIMAP_PREFIX));

from("direct:put")
.setHeader(HazelcastConstants.OPERATION, constant(HazelcastOperation.PUT))
.to(String.format("hazelcast-%sbar", HazelcastConstants.MULTIMAP_PREFIX));

要删除值，您必须提供在消息正文中删除的值。如果您的多映射对象 \{key: "4711" 值：{ "my-foo", "my-bar"}} 需要在消息正文中放置 "my-foo" 来删除 "my-foo" 值。

Java DSL：

from("direct:get")
.setHeader(HazelcastConstants.OPERATION, constant(HazelcastOperation.GET))
.toF("hazelcast-%sbar", HazelcastConstants.MULTIMAP_PREFIX)
.to("seda:out");

from("direct:get")

您可以使用以下方法在测试类中调用它们：

template.sendBodyAndHeader("direct:[put|get|removevalue|delete]", "my-foo", HazelcastConstants.OBJECT_ID, "4711");

template.sendBodyAndHeader("direct:[put|get|removevalue|delete]", "my-foo", HazelcastConstants.OBJECT_ID, "4711");
