在tomcat conf 下的 server.xml 中的

<Resource name="jdbc/egp"
          auth="Container"
          type="javax.sql.DataSource"
          factory="com.alibaba.druid.pool.DruidDataSourceFactory"
          testWhileIdle="true"
          testOnBorrow="true"
          testOnReturn="false"
          validationQuery="SELECT 1"
          validationInterval="30000"
          timeBetweenEvictionRunsMillis="30000"
          maxActive="100"
          minIdle="10"
          maxWait="10000"
          initialSize="10"
          removeAbandonedTimeout="60"
          removeAbandoned="true"
          logAbandoned="true"
          minEvictableIdleTimeMillis="30000"
          username="root"
          password=""
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/egp?useUnicode=true&amp;characterEncoding=utf-8&amp;zeroDateTimeBehavior=convertToNull" />

druid,mysql,的jar包已入到 tomcat/lib下

Tomcat中配置了Realm 使用上面配置的连接池,登录正常,证明OK连接池OK了

<Realm className="org.apache.catalina.realm.DataSourceRealm"
		dataSourceName="jdbc/egp" userTable="v_users" userNameCol="user_name"
		userCredCol="user_pass" userRoleTable="v_roles" roleNameCol="role_name" />

在nutz IOC中配置 ,jdbc/egp 或 java:/comp/env/jdbc/egp 都有试过

{
  "defaultDao": {
    "type": "org.nutz.dao.impl.NutDao",
    "args": [{"jndi":"jdbc/egp"}]
  }
}

调用时报错,
驱动没有载入到?那Realm怎么又OK 的,有请兽叔帮忙看看。。

报错的是org.apache.tomcat.dbcp.dbcp.BasicDataSource

但贴的配置是DruidDataSource

这是奇怪点之一,我根本就没有用过DBCP,但是把JAR包删了又报错。

我想知道的是,为什么ioc实例dao时会找到org.apache.tomcat.dbcp.dbcp.BasicDataSource 而不是javax.sql.DataSource

把jndi名称改成jdbc/dataSource

改了还是一样啊亲,版本是1.r.58,druid-1.0.13

把tomcat连接池的jar干掉, 然后启动,贴报错信息

通过jndi获取DataSource的时候, tomcat容器返回啥就是啥,并不是nutz故意去加载BasicDataSource

tomcat启动时没有报,调用时报了,找不到类

org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.java:115)

ResourceFactory

再是一种情况:

把tomcat的连接池加回去, 然后driud的jar干掉, 贴报错信息

ResourceFactory, 68行,这里是引用dbcp的原因了。

if(ref.getClassName().equals("javax.sql.DataSource")) {
          javaxMailSessionFactoryClassName = System.getProperty("javax.sql.DataSource.Factory", "org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory");

          try {
            factory = (ObjectFactory)Class.forName(javaxMailSessionFactoryClassName).newInstance();
          } catch (Exception var14) {
            ex2 = new NamingException("Could not create resource factory instance");
            ex2.initCause(var14);
            throw ex2;
          }
        }

简直天坑啊....

按你所说的,这就回到之前所说的,找不到classname名的问题。

@wendal 这样就永远用不了druid了。。。晕。。

不是可以设置环境变量吗? env.bat或env.sh里面加

JAVA_OPTS="-Djavax.sql.DataSource.Factory=com.alibaba.druid.pool.DruidDataSourceFactory"

我试了一下8.5.6,正常,不需要额外修改和配置

dao.js配置片段

		dao : {
			type : "org.nutz.dao.impl.NutDao",
			args : [{jndi:"jdbc/DataSource"}],
			fields : {
				//executor : {refer: "cacheExecutor"},
				runner : {refer: "daoRunner"},
				interceptors : [{refer:"cacheExecutor"}, "log", "time"]
			}
		},

tomcat的context.xml配置

<Context>
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
	
	  <Resource
      name="jdbc/DataSource"
      factory="com.alibaba.druid.pool.DruidDataSourceFactory"
      auth="Container"
      type="javax.sql.DataSource"

      maxActive="100"
      maxIdle="30"
      maxWait="10000"
      url="jdbc:mysql://127.0.0.1/nutzbook"
	  username="root"
	  password="root"
      />
</Context>

解决了,解决了,终于解决了。
本来配置在context.xml下还是没问题的。但是。。。
使用了 org.apache.catalina.realm.DataSourceRealm 的原因,连接池必须配置在tomcat server.xml下的GlobalNamingResources位置
在兽叔的指点下,在context.xml加入了,其实这个问题算是低级的,也不怪我,因为从来就没有写过ResourceLink。。。。。
