Question

我试图在mysql数据库中使用两个不同的线程插入。正在通过准备好的声明进行插入。插入500批次。

// g1是实现runnable

的类访问的对象全局

    ExecutorService executor = Executors.newCachedThreadPool();

    Callable< Map<String, Set<String>>> callable2 = new PolyStrain();
    Callable<Map<String, Phenotype>> callable3 =  new DataPolymor();


    g1.kol=new HashMap<String, Set<String>>();

    g1.mapPheno = new HashMap<String, Phenotype>();


    Future<Map<String, Set<String>>> future = executor.submit(callable2); // hashmap of allele and strains
    Future<Map<String, Phenotype>> future1 = executor.submit(callable3); //hashmap of allele and chro,location

    g1.kol = future.get();
    System.out.println(g1.kol.size());


    g1.mapPheno= future1.get();

    System.out.println(g1.mapPheno.size());

    executor.shutdown();

    InsertStrain dp1 = new InsertStrain(); //data entry for allele and strain and frequency
    Thread t1= new Thread(dp1);
    t1.start();

    InsertPheno ip1 = new InsertPheno();
    Thread t2 = new Thread(ip1);
    t2.start();

我面临的问题是，第二个线程已启动，但是它不适用于插入。线程dp1完成其任务。完成dp1后，抛出以下内容：

Lock wait timeout exceeded; try restarting transaction

我已经设置了

mysql> SELECT @@GLOBAL.tx_isolation, @@tx_isolation, @@session.tx_isolation;

此外，

mysql> set innodb_lock_wait_timeout=100

我想知道，即使线程2开始，为什么它不会开始插入？任何帮助都将受到高度赞赏。非常感谢提前。

超过锁定等待超时;尝试重新启动事务
