本文整理了Java中com.hazelcast.config.Config.findMapConfig()方法的一些代码示例，展示了Config.findMapConfig()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Config.findMapConfig()方法的具体详情如下：
包路径：com.hazelcast.config.Config
类名称：Config
方法名：findMapConfig

Config.findMapConfig介绍

[英]Returns a read-only com.hazelcast.core.IMap configuration for the given name.

The name is matched by pattern to the configuration and by stripping the partition ID qualifier from the given name. If there is no config found by the name, it will return the configuration with the name default. For non-default configurations and on-heap maps, it will also initialise the Near Cache eviction if not previously set.
[中]返回只读com。黑泽尔卡斯特。果心给定名称的IMap配置。
该名称通过模式与配置匹配，并从给定名称中剥离分区ID限定符。如果没有通过名称找到配置，它将返回名为default的配置。对于非默认配置和堆映射，如果之前未设置，它还将初始化近缓存逐出。
