下面的type和args代表了什么？

dao : {
            type : "org.nutz.dao.impl.NutDao",
            args : [{refer:"dataSource"}]
        }
29 回复

type是类名，args是构造方法的参数列表

@wendal 但是我没有找到org.nutz.dao.impl.NutDao 这个类呀，这写法是固定的么？

@wendal 还有请问一下里面这些参数都代表什么呀 如果我的MainModule在net.nutz目录下，是这样写没有错么？

@IocBy(type=ComboIocProvider.class, args={"*js", "ioc/",
                                           "*anno", "net.nutz",
                                           "*tx", // 事务拦截 aop
                                           "*async"})

@qq_152b6ff2 没有找到这个类？用的是什么jar？

那是ioc js的格式要求，type/args对应的值都可以变

@wendal = =原来是jar自带的阿。

@wendal 请问为什么找不到ioc呀，我配置的没有错呀。。

你的ioc目录的全路径是什么

@wendal 怎么看全路径= =我就放在conf文件夹下面的ioc里呀

@qq_152b6ff2 是不是conf目录没设置为源文件夹

@wendal conf目录是后面添加进去的。。

http://nutzbook.wendal.net/setup30mins/new_project.html

如果是后面补的, 右键conf文件夹, build path, as source folder.

@wendal 伽利略版的eclipse= =没有build path啊

@wendal 我删了重新建就好啦。还有请问add update insert query 里面测试方法是什么意思呀 @param（）里面的参数是啥？

@wendal 最新问题=-=在自动建表的时候报这个错误

前面建表的语句没写对，是不是pojo的package又写错了

@wendal 弄好了 有点尴尬= =不是很懂又弄错了，写到Mainmodule的路径去了

按nutzbook里面的结构很方便的

@wendal UserModule报错 = =我的UserModule在下面、、

16-12-20 13:46:28.722 DEBUG [http-8080-2] Search mapping for path=/project/count : NOT Action match

public class UserModule {

    @Inject
    protected Dao dao;
    
    //返回project数量
    @At
    public int count() {
        return dao.count(Project.class);
    }
    
    
}

不按nutzbook里面的package结构，是需要多配置些东西的 

@Modules(packages="xxx.xx.xxx", scanPackage=true)

@wendal 请问xxx那个填写说明=-=

@wendal 填写什么。。

@qq_152b6ff2 module类所在的package

@wendal = =又报500了。。好痛苦

@wendal 你好 为什么在控制台可以看到的是正常显示 但是在数据库里面显示会乱码呢？

16-12-20 14:25:49.617 DEBUG [main] INSERT INTO t_project(pid,pname,sqdw,sxmc) VALUES(?,?,?,?)

    |---|-----------|------|-----------|
    | 1 | 绿地卢湾CBD项目 | 绿地集团 | 建设项目选址意见书 |

@qq_152b6ff2 一般是是因为数据库本身不是utf-8

启动日志里面有显示mysql的编码信息

可通过修改jdbcurl或mysql的my.ini修正

@wendal 请问nutz怎么配置charset，在dao.js中配置吗？

@qq_152b6ff2 dao.js里jdbcurl
