transaction-thread项目介绍

保证异步线程能够保证事务的使用工具

说明

  • 此工具是为了解决在使用spring框架下,解决使用异步线程执行任务出现的事务问题。
  • 针对不同的业务使用提供相应api,即可达到目的
  • 通过获取springbean的方式引入即可

特点

  • 支持批量异步任务执行
  • 支持接收异步任务执行结果的功能,调用api时,传入List类型集合参数即可
  • 支持批量异步任务执行,且支持事务,当某个异步任务出现异常事务可回滚
  • 支持主任务批量异步任务的执行,且支持事务,当主任务批量异步任务中只要有一个任务发生异常事务都会回滚
  • 目前异步任务最大数量为100

注意

  • 底层采用的线程池为核心线程数为0,最大线程数为101,因为如果核心数不为0的话,当任务数大于了线程核心数会发生死锁情况。
  • 底层采用的事务级别为READ_COMMITTED,如果采用REPEATABLE_READ,由于mysql在REPEATABLE_READ级别会产生间隙锁,所以可能发生死锁情况。

ThreadTransactionTool工具使用

提供的api

api使用示例

1. public void execute(List taskList)

说明

异步任务运行

public Integer addAccount(int id){
    List<Runnable> runnableList = new ArrayList<>();
    for(int i = 1; i<= 20; i++){
        int temp = i;
        Runnable r = () -> {
            Account account = new Account();
            account.setId(temp);
            account.setAccountId(IdGeneratorUtil.getId());
            account.setName("sss");
            account.setPassword("www");
            account.setAge(temp);
            this.add(account);
        };
        runnableList.add(r);
    }
    threadTransactionTool.execute(runnableList);
    return null;
}

2. public void call(List<Callable> callTaskList,List resultList)

说明

异步任务运行,通过List类型入参拿到异步任务结果。

public Object addAccount(int id){
    List<Callable<Integer>> callableList = new ArrayList<>();
    for(int i = 1; i<= 20; i++){
        int temp = i;
        Callable c = () -> {
            Account account = new Account();
            account.setId(temp);
            account.setAccountId(IdGeneratorUtil.getId());
            account.setName("sss");
            account.setPassword("www");
            account.setAge(temp);
            this.add(account);
            return temp;
        };
        callableList.add(c);
    }
    List<Integer> resultList = new ArrayList<>();
    threadTransactionTool.call(callableList,resultList,true);
    return resultList;
}

3. public void independenceTransactionExecute(List taskList)

说明

异步任务独立事务运行(出现异常回滚本异步任务,其他异步任务不会回滚)

public Integer addAccount(int id){
    List<Runnable> runnableList = new ArrayList<>();
    for(int i = 1; i<= 20; i++){
        int temp = i;
        Runnable r = () -> {
            Account account = new Account();
            account.setId(temp);
            account.setAccountId(IdGeneratorUtil.getId());
            account.setName("sss");
            account.setPassword("www");
            account.setAge(temp);
            this.add(account);
        };
        runnableList.add(r);
    }
    threadTransactionTool.independenceTransactionExecute(runnableList);
    return null;
}  

4. public void independenceTransactionCall(List<Callable> callTaskList,List resultList)

说明

异步任务独立事务运行(出现异常回滚本异步任务,其他异步任务不会回滚),通过List类型入参拿到异步任务结果。

public Object addAccount(int id){
    List<Callable<Integer>> callableList = new ArrayList<>();
    for(int i = 1; i<= 20; i++){
        int temp = i;
        Callable c = () -> {
            Account account = new Account();
            account.setId(temp);
            account.setAccountId(IdGeneratorUtil.getId());
            account.setName("sss");
            account.setPassword("www");
            account.setAge(temp);
            this.add(account);
            return temp;
        };
        callableList.add(c);
    }
    List<Integer> resultList = new ArrayList<>();
    threadTransactionTool.independenceTransactionCall(callableList,resultList);
    return resultList;
}

5. public void transactionExecute(List taskList)

说明

处理异步执行的任务

public Integer addUserAndAccount(User user){
    long startTime = System.currentTimeMillis();
    Integer result = userMapper.add(user);

    List<Runnable> runnableList = new ArrayList<>();
    for(int i = 1; i<= 20; i++){
        int temp = i;
        Runnable r = () -> {
            Account account = new Account();
            account.setId(temp);
            account.setAccountId(IdGeneratorUtil.getId());
            account.setName("sss");
            account.setPassword("www");
            account.setAge(temp);
            accountService.add(account);
        };
        runnableList.add(r);
    }

    try {
        threadTransactionTool.transactionExecute(runnableList);
    } catch (Throwable e) {
        System.out.println("===检测到异常回滚!!!===");
        TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
    }

    long endTime = System.currentTimeMillis();
    System.out.println("===耗时:"+(endTime - startTime)+"===");
    return result;
}

特点

批量异步任务执行时,当其中一个出现异常后,其余的异步任务都会回滚。但是当主任务添加user的操作出现异常,异步任务不会回滚,需要使用threadTransactionTool提供的另外方法api。

6. public void transactionCall(List<Callable> callTaskList, List resultList)

说明

处理异步执行的任务,并拿到异步任务结果

public Object addUserAndAccount(User user){
    long startTime = System.currentTimeMillis();

    Integer result = 0;
    List<Callable<Integer>> callableList = new ArrayList<>();
    for(int i = 1; i<= 20; i++){
        int temp = i;
        Callable call = () -> {
            Account account = new Account();
            account.setId(temp);
            account.setAccountId(IdGeneratorUtil.getId());
            account.setName("sss");
            account.setPassword("www");
            account.setAge(temp);
            accountService.add(account);
            return temp;
        };
        callableList.add(call);
    }

    List<Integer> resultList = new ArrayList<>();
    try {
        threadTransactionTool.transactionCall(callableList,resultList);
    } catch (Throwable e) {
        System.out.println("===检测到异常回滚!!!===");
        TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
    }

    long endTime = System.currentTimeMillis();
    System.out.println("===耗时:"+(endTime - startTime)+"===");
    return resultList;
}

特点

介绍5的api增强了接收异步结果的功能,通过传入resultList参数实现。

7. public void transactionExecute(MajorTaskRunnable majorTaskRunnable, List taskList)

说明

public Integer addUserAndAccount(User user){
    long startTime = System.currentTimeMillis();

    Integer result = 0;
    List<Runnable> runnableList = new ArrayList<>();
    for(int i = 1; i<= 20; i++){
        int temp = i;
        Runnable r = () -> {
            Account account = new Account();
            account.setId(temp);
            account.setAccountId(IdGeneratorUtil.getId());
            account.setName("sss");
            account.setPassword("www");
            account.setAge(temp);
            accountService.add(account);
        };
        runnableList.add(r);
    }
    try {
        threadTransactionTool.transactionExecute(() -> {
            userMapper.add(user);
        }, runnableList);
    } catch (Throwable e) {
        System.out.println("===检测到异常回滚!!!===");
        TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
    }

    long endTime = System.currentTimeMillis();
    System.out.println("===耗时:"+(endTime - startTime)+"===");
    return result;
}

特点
