问答 NutTxDao使用中的问题

标签: 无

使用的是Oracle数据库，是最简单的基本配置

NutTxDao tran=new NutTxDao(dao).setDebug(true);           
tran.beginRC();

这里多次执行，偶尔正常，总是存在出现如下错误的情况：
java.sql.SQLException: 调用中的无效参数
多次刷新，错误多次出现后，就出现下面错误
com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 15001, active 8, maxActive 8
必须重启应用才可以的

  For example:> "SELECT * FROM dbm_submit  WHERE parentId='9ad4b6c74d0e4fe0bad3c05858f19e11'"

/**
     * 获取数据对象对应Dao
     * @param database
     * @return
     */
    public Dao getDao(Dbm_database database){
        Dao _dao =null;
        if(Daos.containsKey(database.getId())){
            _dao= Daos.get(database.getId());
        }
        else {
            DruidDataSource dataSource = new DruidDataSource();
            dataSource.setUrl(database.getUrl());
            dataSource.setUsername(database.getUsername());
            dataSource.setPassword(database.getPassword());
            dataSource.setDefaultAutoCommit(database.isDefaultAutoCommit());
            dataSource.setMaxWait(database.getMaxWait());
            _dao = new NutDao(dataSource);
            Daos.put(database.getId(),_dao);
            Databses.put(database.getId(),dataSource);
        }
        return _dao;
    }

数据库连接没有释放的样子, 调用代码里面没加finally?

public void Close(String databaseId){
        if(Databses.containsKey(databaseId)){
            Databses.get(databaseId).close();
            Databses.remove(databaseId);
            Daos.remove(databaseId);
        }
    }

执行这个也是同样问题，感觉无用

try {
            for (NutMap nutMap : list) {
                this.submit(submit, nutMap,trans);
            }
            result.setData(list);
            for(String databaseId:trans.keySet()) {
                trans.get(databaseId).commit();
            }
        } catch (Throwable e) {
            for(String databaseId:trans.keySet()) {
                trans.get(databaseId).rollback();
            }
            throw Lang.makeThrow(e.getMessage());
        }
        finally {
            for(String databaseId:trans.keySet()) {
                dbmDatabaseService.Close(databaseId);
            }
        }

关闭数据库连接后：
java.sql.SQLException: 调用中的无效参数
这个错误出现，

这个错误
com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 15001, active 8, maxActive 8
就不出现了

虽然我这里使用的支持多个数据库的方式，但出现错误的时候只有一个数据库参与事务！

NutTxDao相关的代码

private void submit(Dbm_submit submit, NutMap nutMap,Map<String,NutTxDao> trans) {
        Dao dao = dbmDatabaseService.getDao(submit.getDatabaseId());
        if(!trans.containsKey(submit.getDatabaseId())){
            NutTxDao tran=new NutTxDao(dao).setDebug(true);
            trans.put(submit.getDatabaseId(),tran);
            tran.beginRC();
        }

然后就没有了??

后面的就是使用这个dao进行数据库的insert,update

仔细看文档 http://nutzam.com/core/dao/trans_session.html

Map<String,NutTxDao> trans =new HashMap<>();
        try {
            for (NutMap nutMap : list) {
                this.submit(submit, nutMap,trans);
            }
            result.setData(list);
            for(String databaseId:trans.keySet()) {
                trans.get(databaseId).commit();
            }
        } catch (Throwable e) {
            for(String databaseId:trans.keySet()) {
                trans.get(databaseId).rollback();
            }
            throw Lang.makeThrow(e.getMessage());
        }
        finally {
            for(String databaseId:trans.keySet()) {
                dbmDatabaseService.Close(databaseId);
            }
        }

 private void submit(Dbm_submit submit, NutMap nutMap,Map<String,NutTxDao> trans) {
        Dao dao = dbmDatabaseService.getDao(submit.getDatabaseId());
        if(!trans.containsKey(submit.getDatabaseId())){
            NutTxDao tran=new NutTxDao(dao).setDebug(true);
            trans.put(submit.getDatabaseId(),tran);
            tran.beginRC();
        }
        dao.insert("test",chain):
}

必死无疑... 自行看文档吧

看了好几次，找不出问题所在呀！提示一下！

看到了，close

try {
            for (NutMap nutMap : list) {
                this.submit(submit, nutMap,trans);
            }
            result.setData(list);
            for(String databaseId:trans.keySet()) {
                trans.get(databaseId).commit();
            }
        } catch (Throwable e) {
            for(String databaseId:trans.keySet()) {
                trans.get(databaseId).rollback();
            }
            result.setCode(1);
            result.setMsg(e.getMessage());
        }
        finally {
            for(String databaseId:trans.keySet()) {
                trans.get(databaseId).close();
            }
        }

java.sql.SQLException: 调用中的无效参数
这个错误还是出现，

问题在于你调用NutTxDao的那段代码, 不是trans之类的东西

NutTxDao的调用必须按下面的范式

try (NutTxDao tx = new ....) {
   xxxxx..x..x..x
    tx.commit();
}
catch () {
    tx.rollback();
}
finally {
    tx.close()
}

任何新建的NutTxDao对象, 最起码要调用close

我这里的trans仅仅是一个map的实例，保存NutTxDao实例的容器呀！

就拿这个说

 private void submit(Dbm_submit submit, NutMap nutMap,Map<String,NutTxDao> trans) {
        Dao dao = dbmDatabaseService.getDao(submit.getDatabaseId());
        if(!trans.containsKey(submit.getDatabaseId())){
            NutTxDao tran=new NutTxDao(dao).setDebug(true);
            trans.put(submit.getDatabaseId(),tran);
            tran.beginRC();
        }
        dao.insert("test",chain): // 这里要操作tran啊
}

擦, 你先把代码整理整理吧

好的，我完全按你的方式写写试试！

public Result submit(int authType,Dbm_submit submit, List<NutMap> list) {
        if (submit.getAuthType() > authType) {
            throw Lang.makeThrow("您暂不具有对应数据操作权限");
        }
        Result result = new Result();
        Map<String,NutTxDao> trans =new HashMap<>();
        dao = dbmDatabaseService.getDao(submit.getDatabaseId());
        NutTxDao tx=new NutTxDao(dao);
        try {
            tx.beginRC();
            for (NutMap nutMap : list) {
                this.submit(submit, nutMap,trans);
            }
            result.setData(list);           
            tx.commit();
        } catch (Throwable e) {            
            tx.rollback();
            result.setCode(1);
            result.setMsg(e.getMessage());
        }
        finally {
            tx.close();         
        }
        return result;
    }

错误依旧

dao是类里面的私有全局变量

创建连接池的时候配一下这个 https://github.com/alibaba/druid/wiki/%E8%BF%9E%E6%8E%A5%E6%B3%84%E6%BC%8F%E7%9B%91%E6%B5%8B
看看是哪里泄露的

OK

dataSource.setRemoveAbandoned(true);
            dataSource.setRemoveAbandonedTimeout(1800);
            dataSource.setLogAbandoned(true);

问题依旧

是让你看泄露的代码... 配置这个是不能解决泄露的,但会打印泄露的日志

我写了个入口方法测试了一下, 循环1000次,创建然后close, 没有泄露

    @At
    public void tx() {
        for (int i = 0; i < 1000; i++) {
            NutTxDao tx = new NutTxDao(dao);
            try {
                tx.beginRC();
                tx.query(User.class, null);
                tx.commit();
            } catch (Throwable e) {
                tx.rollback();
            }
            finally {
                tx.close();
            }
        }
    }

我看了日志，没有泄露日志！奇怪了！我现在执行10次至少有2次出错！

是否与oracle有关呀！

试一下我的测试代码

话说, 你这maxActive才8个, 也太少了吧

嗯，我现在修改为100个试试

Dao dao = dbmDatabaseService.getDao(submit.getDatabaseId());
        for (int i = 0; i < 1000; i++) {
            NutTxDao tx = new NutTxDao(dao);
            try {
                tx.beginRC();
                tx.query("im_units", null);
                tx.commit();
            } catch (Throwable e) {
                tx.rollback();
                result.setCode(1);
                result.setMsg(e.getMessage());
                break;
            }
            finally {
                tx.close();
            }
        }
        return result;

只可以执行一次成功，循环第二次就报错！

贴报错信息看看

同样的代码，我用mysql就没有问题，用oracle就是出错

public Result submit(int authType, String submitId, List<NutMap> list) {
        Dao dao=dbmDatabaseService.getDao("9ad4b6c74d0e4fe0bad3c05858f19e1f");
        Result result = new Result();
        for (int i = 0; i < 1000; i++) {
            NutTxDao tx = new NutTxDao(dao);
            try {
                tx.beginRC();
                tx.query("im_units", null);
                tx.commit();
            } catch (Throwable e) {
                tx.rollback();
                result.setCode(1);
                result.setMsg(e.getMessage());
                break;
            }
            finally {
                tx.close();
            }
        }
        return result;
    }

setSavepoint失败,奇怪了,驱动版本多少?? 数据库版本多少?

驱动版本：

<dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0</version>
        </dependency>

数据库是oracle11g

额, 难道是Savepoint的Name太长了?

这样写,看看是否报错

晚上我装个oracle试试看，诡异了，难道不能走命名save point的？我印象中是可以的啊

ok，期待你的好消息

重现了

    public NutTxDao setSavepoint(String spId) {
        try {
            Savepoint sp = conn.setSavepoint(); // 不加spId就正常,回滚也没问题
            if (id.equals(spId))
                this.sp = sp;
            else {
                if (sps == null)
                    sps = new NutMap();
                sps.put(spId, sp);
            }
        }
        catch (SQLException e) {
            throw new DaoException(e);
        }
        return this;
    }

我提交修改了

更新后完美解决！
