135.3. 将缓存制作者 - 映射到("hazelcast-map:foo")

135.3. 将缓存制作者 - 映射到("hazelcast-map:foo")

如果要在映射中存储值，您可以使用映射缓存制作者。

映射缓存制作者提供由 CamelHazelcastOperationType 标头指定的后续操作：

put
putIfAbsent
get
getAll
keySet
containsKey
containsValue
delete
update
query
clear
Evict
evictAll

所有操作都在 "hazelcast.operation.type" 标头变量内提供。在 Java DSL 中，您可以使用 org.apache.camel.component.hazelcast.HazelcastOperation 中的常量。

请求消息的标头变量：

Expand

名称	类型	描述
`CamelHazelcastOperationType`	`字符串`	如已描述。
`CamelHazelcastObjectId`	`字符串`	在缓存中存储 / 的对象 id （不需要查询操作）

放置 和放置IfAbsent 操作提供驱除机制：

Expand

名称	类型	描述
`CamelHazelcastObjectTtlValue`	`整数`	TTL 的值。
`CamelHazelcastObjectTtlUnit`	`java.util.concurrent.TimeUnit`	时间单位的值（DAYS / HOURS / MINUTES / ….

您可以使用以下方法调用示例：

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

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

对于查询操作 Hazelcast，提供类似语法的 SQL 来查询您的分布式映射。

String q1 = "bar > 1000";
template.sendBodyAndHeader("direct:query", null, HazelcastConstants.QUERY, q1);

String q1 = "bar > 1000";
template.sendBodyAndHeader("direct:query", null, HazelcastConstants.QUERY, q1);
