示例代码：

https://github.com/gordonklg/study，cache module

A. 实例

gordon.study.cache.ehcache3.basic.XmlConfig.java

public class XmlConfig {

    public static void main(String[] args) {

        final URL myUrl = XmlConfig.class.getResource("/ehcache3_basic.xml");

        Configuration xmlConfig = new XmlConfiguration(myUrl);

        CacheManager cacheManager = CacheManagerBuilder.newCacheManager(xmlConfig);

        cacheManager.init();

        Cache<String, UserModel> phoneUserCache = cacheManager.getCache("phoneUserCache", String.class, UserModel.class);

        UserModel user = new UserModel("13316619988", "abc@123.com", "openid12345", "very very long user information ...");

        phoneUserCache.put(user.getPhone(), user);

        UserModel cached = phoneUserCache.get(user.getPhone());

        System.out.println(cached.getInfo());

    }

}

示例代码简单明了，没啥好说的。

ehcache3_basic.xml in src/main/resources

<?xml version="1.0" encoding="UTF-8"?>

<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'

    xmlns='http://www.ehcache.org/v3' xmlns:jsr107='http://www.ehcache.org/v3/jsr107'

    xsi:schemaLocation="

        http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.2.xsd

        http://www.ehcache.org/v3/jsr107 http://www.ehcache.org/schema/ehcache-107-ext-3.2.xsd">

    <cache-template name="userTemplate">

        <key-type>java.lang.String</key-type>

        <value-type>gordon.study.cache.ehcache3.basic.UserModel</value-type>

        <heap unit="entries">5</heap>

    </cache-template>

    <cache alias="phoneUserCache" uses-template="userTemplate">

        <heap unit="entries">20</heap>

    </cache>

    <cache alias="emailUserCache" uses-template="userTemplate" />

</config>

配置文件同样简单明了。其中 cache-template 为缓存模板，可以简化配置。
