问答 来来来，兽哥！来聊下Ehcache怎么玩！
发布于 3124天前 作者 明天会吹什么风 3492 次浏览 复制 上一个帖子 下一个帖子
标签: ehcache

发现了个有意思的，搞了老久才发现毛病，但是你懂得，屌丝找不出原理！
开始重现了： 

Account account = new Account();
account.setMobile(username);
dao.fetch(Account.class, Cnd.from(dao, account));

这是一段没毛病的代码，运行正常的。
好的，加上Ehcache吧！
按照配置，配置了需要缓存的表
按照nutzbookdao.js

...
cachedTableNames : ['accounts']
...

抛锚了，
注意sql，： org.nutz.plugins.cache.dao.CachedNutDaoExecutor.exec(CachedNutDaoExecutor.java:120) DEBUG - sql = SELECT * FROM accounts WHERE (mobile=?) LIMIT 0, 1 , tables = [accounts]
有点儿意思！
兽哥v5！！！

看不出啥抛锚了

楼主的意思是没有缓存？还是执行了SQL？
貌似配置表名之后还要手动缓存。。。
也许是我学艺不精。。。求鞭策！

@qq_74967e40 不需要手动缓存，第一次查询的时候因为没有命中，所以查数据库，并自动存入缓存，第二次查自然命中了，不再会查数据库，直到缓存失效（有插入，删除，更新，或idle时间到了

那是我哪儿配置错了把，我都是手动。不然，每次都显示执行了SQL

我很好奇你怎么手动的

Element ele = cacheManager.getCache("mz").get(eleKey);
if(null == ele){
queryResult = ...
cacheManager.getCache("mz").put(new Element(eleKey,queryResult));
}else{
queryResult = (QueryResult) ele.getObjectValue();
}

就是这样

@qq_74967e40 这属于应用层管理一个Cache，不是daocache做的事。 daocache做的事，可以这样理解 dao.fetch多次，相同条件，仅第一次会执行数据库查询，剩下N次都从缓存取。

@wendal 是不是分页的时候，是不会缓存的？还是说会按照配置里的表来，对这个表的查询都会缓存？

相同查询条件相同分页，生成的sql一样，参数一样，才算匹配

@qq_74967e40 分页与否都会缓存

@wendal 我不知道哪儿有问题，就是不会自动缓存。。。
项目启动不会报错
catchManager也没问题，能报启动信息。
dao里配置也照搬的
不明白了

@qq_74967e40 有一种可能性是调用时在Trans.exec的作用域

默认配置下，如果在事务内，不读缓存

执行语句dao.fetch(Account.class, Cnd.from(dao, account));

daocache版本不是最新吧?

是最新的，版本跟nutbook一致，
不加... cachedTableNames : ['accounts'] ...这个还好，
加了就不行

既然是抛空指针，那找出来什么变量为null。目测是ehcacheManager为null，然后ehcache.js里面的注释没看清楚。里面有写，如果单独用ehcache，是用create，如果是与shiro共用，就用get

因为报错信息里面指向这一行:

即

Cache cache = cacheManager.getCache(name);

所以是cacheManager为null

然后呢, 你在MainSetup里面有这样的代码

		CacheManager cacheManager = ioc.get(CacheManager.class);
		CachedNutDaoExecutor.DEBUG = true;// 开启详细日志
		//log.debug("Ehcache CacheManager = " + cacheManager);

最后的 log.debug 被注释了, 取消注释, 看看打印的是不是null吧, 估计也是

所以呢, 问题就出在ehcache.js的了, 然后你提供的shiro.ini配置显示ehcache是启用了(而且名字就叫app), 理应是shiro初始化完成就有ehcache实例

可能性有:

  1. Shiro/ShiroFilter比NutFilter晚初始化
  2. Shiro就没启动

打印是null的

//动作链。以下配置仅比默认配置多了一个vc.thinker.mvc.LogTimeProcessor
var chain = {
	"default" : {
		"ps" : [ 
			"vc.thinker.mvc.processor.LogTimeProcessor",//自定义
			"org.nutz.mvc.impl.processor.UpdateRequestAttributesProcessor",
			"org.nutz.mvc.impl.processor.EncodingProcessor",
			"org.nutz.mvc.impl.processor.ModuleProcessor",
			"vc.thinker.shiro.NutShiroProcessor",//自定义
//			"ioc:demoProcessor",//自定义,直接注入ioc bean
			"vc.thinker.mvc.processor.DemoProcessor",
			"org.nutz.mvc.impl.processor.ActionFiltersProcessor",
			"org.nutz.mvc.impl.processor.AdaptorProcessor",
			"!org.nutz.plugins.validation.ValidationProcessor",//默认不启用，去掉 '!'可改为启用
			"org.nutz.mvc.impl.processor.MethodInvokeProcessor",
			"org.nutz.mvc.impl.processor.ViewProcessor" 
		],
		"error" : 'org.nutz.mvc.impl.processor.FailProcessor'
	}
};

可能性有:

  1. Shiro/ShiroFilter比NutFilter晚初始化, web.xml里面顺序
  2. Shiro就没启动

shiro可以正常使用

把启动日志贴到 短点 然后把地址贴过来吧
自豪地采用 NutzCN ionic

真神奇, 看看你得debug一下CacheManager的getCacheManager方法了, 看看传入的name是啥, 然后CACHE_MANAGERS_MAP里面有啥

    public static CacheManager getCacheManager(String name) {
        synchronized (CacheManager.class) {
            if (name == null) {
                name = DEFAULT_NAME;
            }
            return CACHE_MANAGERS_MAP.get(name);
        }
    }

这里的name 和配置的一致

唉。。。。。。。。。。。。。。

终于发现点痕迹, 你的日志里面有这样一段

2015-10-10 11:35:33,663 org.apache.shiro.realm.AuthorizingRealm.getAuthorizationCacheLazy(AuthorizingRealm.java:242) DEBUG - CacheManager [org.apache.shiro.cache.ehcache.EhCacheManager@17088d81] has been configured.  Building authorization cache named [nutzdao_realm.authorizationCache]

正常是这样, 找到一个自定义的ehcache.xml

2015-10-10 14:11:15,293 org.apache.shiro.realm.AuthorizingRealm.getAuthorizationCacheLazy(AuthorizingRealm.java:242) DEBUG - CacheManager [org.apache.shiro.cache.ehcache.EhCacheManager@12a5143] has been configured.  Building authorization cache named [nutzdao_realm.authorizationCache]

;###########配置ehcache
cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
cacheManager.cacheManagerConfigFile=classpath:ehcache.xml
securityManager.cacheManager = $cacheManager

这段要配置在前

换了顺序，异常了 异常

1.首先是顺序问题

;###########配置ehcache
cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
cacheManager.cacheManagerConfigFile=classpath:ehcache.xml
securityManager.cacheManager = $cacheManager

;此处的加密算法必须和业务的加密算法一致
sha256Matcher = org.apache.shiro.authc.credential.Sha256CredentialsMatcher
nutzdao_realm.cacheManager = $cacheManager
nutzdao_realm = vc.thinker.shiro.realm.NutDaoRealm
nutzdao_realm.credentialsMatcher = $sha256Matcher

2.ehcache.xml中配置的缓存路径.这里配置多了，还有要么就是创建不了

<diskStore path="java.io.tmpdir/app" />
<diskStore path="/data/app_cache/" />

至今最长的楼... 终于解决了

论看清楚注释的重要性
