问答 在module加入@inject Dao dao ;访问报错

加入 下面代码到子模块

@Inject
private Dao dao;

然后随便访问哪个入口 就报错

@Api("time")
@At("/time")
@IocBean(create="init", depose="depose")
public class TimeModule {
    
    @Inject
    protected PropertiesProxy conf;
    @Inject
    private Dao dao;
    
    @ApiOperation(value = "获取当前毫秒数", notes = "服务器端的时间", httpMethod="GET", response=Long.class)
    @At
    @Ok("raw")
    public long now() {
        return System.currentTimeMillis();
    }
    
    public void init() {}
    public void depose() {}

}

ioc.js

var ioc={
    conf : {
        type : "org.nutz.ioc.impl.PropertiesProxy",
        fields : {
            paths : ["db.properties"]
        }
    },
	fileSqlManager : {
		type: "org.nutz.dao.impl.FileSqlManager"
		args: ["sqls"]
	},
	dataSource : {
		type : "org.nutz.dao.impl.SimpleDataSource",
		events : {
			depose : "close"
		},
		fields : {
			driverClassName :{	java : "$conf.get('db-driver')"},
			jdbcUrl             : {java :"$conf.get('db-url')"},
			username        : {java :"$conf.get('db-username')"},
			password        : {java :"$conf.get('db-password')"},
		}
	}
	,
	dao : {
		type : 'org.nutz.dao.impl.NutDao',
		args : [ {refer : "dataSource"} ,{refer:"fileSqlManager"}]
	}}

但是单元测试可以通过,还能用dao查询

db.properties

db-driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
db-url=jdbc:sqlserver://192.168.0.4;DatabaseName=test
db-username=sa
db-password=******

这是nutzboot??

是nutz

再把主模块贴一下

@IocBean(create = "init", depose = "depose")
@IocBy(args = { "*js", "ioc/", "*anno", "com.boyuan", "*tx", "*async", "48", })
@Modules(scanPackage = true) 
public class MainLauncher {
	private static final Log log = Logs.getLog(MainLauncher.class);
	@Inject
	protected PropertiesProxy conf;

	@At("/")
	@Ok("->:/index.html")
	public void index() {
	}

	public void init() {
		// NB自身初始化完成后会调用这个方法
		log.info("服务初始化完毕");
	}

	public void depose() {
		log.info("服务结束");
	}

	public static void main(String[] args) throws Exception {
		new NbApp().setArgs(args).setPrintProcDoc(true).run();
	}

}

这是nutzboot呢, 除非那个main方法是忘记删掉了

嗯.从NB生成器生成的,nutzboot 单元测试能查的 但是启动服务再访问就报错了

既然是nutzboot项目, 按nutzboot的规则做, 配置信息是放在application.properties里面的, dao.js是多余的

好的
