dbType not support : null, url jdbc:highgo://10.1.1.220:5866/dbName

highgo数据库?没听说过啊

识别不了,会回落为mysql模式

@wendal 就是国内自己改的postgres,有自己的驱动(也是改的). 能提供支持me

哦,应该是兼容pgsql的吧,改一下nutz_jdbc_expert.js就好了

@wendal
我拷贝了一份expert.js到项目里,
增加了一行:

//翰高数据库
"highgo.*" : "org.nutz.dao.impl.jdbc.psql.PsqlJdbcExpert",

数据库连接信息如下:

  datasource:
    url: jdbc:highgo://10.1.1.220:5866/dbName
    driver-class-name: com.highgo.jdbc.Driver
    username: highgo
    password: highgo
    sql-script-encoding: utf-8

但是报错:

什么鬼👻...??

写个main方法测试一下

@wendal 如果把最后面的 "dm dbms.*" : "org.nutz.dao.impl.jdbc.dm.DmJdbcExpert" 这行删掉就能正常使用dao了. 啥原因呢?

是不是json格式错了, 整个js文件贴来看看

/*
 * Nutz.Dao 的默认支持数据库的种类
 */
var ioc = {

    /*
     * Experts 的映射列表
     */
    experts : {
        "h2.*" : "org.nutz.dao.impl.jdbc.h2.H2JdbcExpert",
        "mysql.*" : "org.nutz.dao.impl.jdbc.mysql.MysqlJdbcExpert",
        "postgresql.*" : "org.nutz.dao.impl.jdbc.psql.PsqlJdbcExpert",
        //翰高数据库

        // ~ 映射结束
    },

    /*
     * 所有 Expert 都能读到这个配置文件
     */
    config : {
        // 默认的 Clob 以及 Blog 临时目录
        "pool-home" : "~/.nutz/tmp/dao/",
        // 临时目录大小,0 为不限大小
        "pool-max" : 200000,
        // Mysql 特殊配置
        "mysql-engine" : "InnoDB",
        // GBase 特殊配置
        "gbase-engine" : "GsDB"
        // ~ 配置信息结束
    } };

是不是你的nutz.jar没有org.nutz.dao.impl.jdbc.dm.DmJdbcExpert类???

我用的1.r.62 官方包啊, 不过里面的确没有DmJdbcExpert这个类

恩, 你拷贝的是最新的, 删掉就好了

来个pull req不(;`O´)o
