134.3.5. 查询示例

Java DSL：

from("direct:query")
.setHeader(HazelcastConstants.OPERATION, constant(HazelcastOperation.QUERY))
.toF("hazelcast-%sfoo", HazelcastConstants.MAP_PREFIX)
.to("seda:out");

Spring DSL：

<route>
    <from uri="direct:query" />
        <!-- If using version 2.8 and above set headerName to "CamelHazelcastOperationType" -->
    <setHeader headerName="hazelcast.operation.type">
        <constant>query</constant>
    </setHeader>
    <to uri="hazelcast-map:foo" />
    <to uri="seda:out" />
</route>

对于查询操作 Hazelcast 提供了 SQL （如语法）以查询您的分布式映射。

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