你好，请帮我看下这个问题，谢谢。我用的1.60。用的这段代码：

Map<String,Object> map = new HashMap<String,Object>();
			map.put(".table", "Entity_ZBJL");
			map.put("uuid", UUID.randomUUID().toString());
			map.put("muser", user);
			map.put("x", x);
			map.put("y", y);
			map.put("jlsj", new Date());
			dao.insert(map);

下面是后台日志：

2017-03-13 17:37:20,737 org.nutz.dao.impl.sql.run.NutDaoExecutor.printSQL(NutDaoExecutor.java:388) DEBUG - INSERT INTO Entity_ZBJL(muser,jlsj,uuid,y,x) VALUES(?,?,?,?,?)

  For example:> "INSERT INTO Entity_ZBJL(muser,jlsj,uuid,y,x) VALUES(7,'2017-03-13 17:37:20','f2147c47-e1d7-4ce9-95ed-8572ec875b17','45.6074318','84.86561041') "

有时候能插入记录，有时候无法插入，可是又没有报错？
表结构是这样的：
CREATE TABLE "TLFDJGL"."ENTITY_ZBJL"
( "UUID" VARCHAR2(50 BYTE),
"MUSER" NUMBER(12,0),
"X" VARCHAR2(30 BYTE),
"Y" VARCHAR2(30 BYTE),
"JLSJ" DATE
)

dao.js是这样的：

var ioc = {
        conf : {
            type : "org.nutz.ioc.impl.PropertiesProxy",
            fields : {
            		paths : ["custom/"]
            }
        },
        dataSource : {
            type : "com.alibaba.druid.pool.DruidDataSource",
            events : {
                create : "init",
                depose : 'close'
            },
            fields : {
                url : {java:"$conf.get('db.url')"},
                username : {java:"$conf.get('db.username')"},
                password : {java:"$conf.get('db.password')"},
                testWhileIdle : true,
                validationQuery : {java:"$conf.get('db.validationQuery')"},
                maxActive : {java:"$conf.get('db.maxActive')"},
                filters : "mergeStat",
                connectionProperties : "druid.stat.slowSqlMillis=2000"
            }
        },
        dao : {
            type : "org.nutz.dao.impl.NutDao",
            args : [{refer:"dataSource"}]
        }
};

db.properties是这样的：

db.url=jdbc:oracle:thin:@127.0.0.1:1521/orcl
db.username=djgl
db.password=000000
db.validationQuery=select 1 from dual
db.maxActive=100
