本发明的实施方式
下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请实施例提供一种线程执行方法、装置、电子设备及计算机可读存储介质。具体地，本申请实施例提供适用于电子设备的线程执行装置，其中，电子设备包括终端或者服务器等设备，其中，终端可以为计算机、个人笔记本或者手机等设备，服务器可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、内容分发网络（CDN，Content Delivery Network）、以及大数据和人工智能平台等基础云计算服务的云服务器，服务器可以通过有线或无线通信方式进行直接或间接地连接。
本申请实施例可以单独由终端设备执行线程执行方法，或者是单独由服务器执行线程执行方法，或者是终端设备和服务器共同执行线程执行方法，请参阅图1，以终端设备和服务器共同执行线程执行方法为例，其中，在终端设备和服务器的基础上也可以增加其他设备来辅助完成线程执行方法，在此对其他设备的类型不做限定；终端设备与服务器之间通过网络连接，比如，通过无线网络连接等，具体执行过程如下：
终端设备10在响应用户的触发操作后，触发执行相应的线程（如主线程），线程在执行过程中唤醒相应的子线程，由主线程和相应的子线程共同执行完成用户触发操作的响应或反馈。
其中，服务器11在检测到线程之间发生唤醒操作时，根据唤醒线程（如第一线程）的当前优先级确定目标优先级，将目标优先级发送给被唤醒线程（如第二线程），并根据目标优先级执行被唤醒线程。
其中，在本申请实施例中，唤醒线程可以包括前台应用的主线程，被唤醒线程可以包括后台应用的主线程，相应的，用户在终端设备的用户界面触发操作后，触发执行前台应用主线程的执行，随后，前台应用主线程通过唤醒后台应用主线程进行相应的响应反馈。
其中，本申请实施例在检测到第一线程唤醒第二线程时，根据第一线程的当前优先级确定目标优先级，并将目标优先级传递给第二线程，使得第二线程能够根据目标优先级进行执行，其中，通过对被唤醒通信的线程的优先级的调整，可在提升被唤醒的线程的优先级后，实现被唤醒线程的优先执行，提升执行效率。
以下分别进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优先顺序的限定。
请参阅图2，图2为本申请实施例提供的线程执行方法的流程示意图。该线程执行方法的具体流程可以如下：
101、当检测到第一线程唤醒第二线程时，根据所述第一线程的当前优先级，确定目标优先级。
其中，线程（thread）是操作系统能够进行运算调度的最小单位。它被包含在进程之中，是进程中的实际运作单位。一条线程指的是进程中一个单一顺序的控制流，一个进程中可以并发多个线程，每条线程并行执行不同的任务。在Unix System V及SunOS中也被称为轻量进程（lightweight processes），但轻量进程更多指内核线程（kernel thread），而把用户线程（user thread）称为线程。
例如，在安卓林纳斯（Linux）桌面系统中，场景动态的设置依赖于线程的执行，而各个线程的执行依赖于相应优先级的配置，如，前台应用线程的优先级与后台应用的优先级不同，一般来说，高优先级的线程要优先于低优先级线程的执行，而通过对各个线程优先级的配置，使得各个线程能够有序执行。
其中，线程在执行过程中并非全部是各自独立的，即存在部分线程需要唤醒其他线程来协同执行完成系统任务的情况，例如，主线程可以将耗时较长的任务分配给子线程去完成，由主线程唤醒子线程的执行，或者，主线程将一部分任务分配给子线程，并根据子线程的执行结果来完成主线程后续任务的执行。
其中，在本申请实施例中，第一线程指发起唤醒其他线程的线程，在本申请实施例中，第一线程可以包括前台应用对应的主线程。
其中，在本申请实施例中，第二线程指被其他线程唤醒的线程，在本申请实施例中，第二线程可以包括后台应用对应的主线程。
其中，在本申请实施例中，第一线程对第二线程的唤醒包括第一线程调用函数（handler）向第二线程发送信息（message），第二线程在收到信息（message）后开始运行，实现第一线程对第二线程的唤醒。
其中，由于第二线程即被唤醒的线程一般包括子线程，而子线程的执行优先级较低，而较低的优先级使得线程获取执行结果的时间较长，难以实现对第一线程的执行结果的及时回馈，因此，在本申请实施例中，通过确定目标优先级，对第二线程进行优先级调整，缩短第二线程获取执行结果的时间，提升第二线程获取执行结果的效率。
其中，目标优先级的确定用于对第二线程的优先级调整，其中，通过第一线程的优先级确定目标优先级，可使得第二线程的优先级能够与第一线程的优先级相互匹配，便于实现第二线程与第一线程的协调执行。
102、将所述目标优先级传递给所述第二线程，并根据所述目标优先级执行所述第二线程。
其中，通过根据第一线程的优先级确定的目标优先级，并根据目标优先级对第二线程的执行进行调度，可实现第二线程与第一线程的协调执行。
例如，在本申请实施例中，当第一线程依赖于第二线程的执行结果才能进行执行时，可以将第二线程的优先级进行适当的提升，以减少第一线程的执行等待，避免执行阻塞或者形成卡顿现象，提高执行效率。
再例如，在本申请实施例中，当系统任务的执行依赖于多个线程时，且存在有第一线程唤醒执行第二线程时（此时第一线程的执行不依赖于第二线程的执行结果，仅存在唤醒多个子线程的情况），第二线程的执行效率或者开始执行时间影响系统整体任务的执行效率，因此，可以根据第一线程的优先级对第二线程的优先级进行调整，以加快第二线程的执行，加快系统整体任务的执行效率。
其中，在本申请实施例中，还可以根据第二线程的执行结果来进行第一线程的执行，即，可选的，在本申请的一些实施例中，步骤“将所述目标优先级传递给所述第二线程，并根据所述目标优先级执行所述第二线程”之后，该方法还包括：
基于所述唤醒，将所述第二线程的执行结果返回给所述第一线程，其中，所述执行结果是所述第二线程根据所述目标优先级执行后得到的；
根据所述执行结果进行所述第一线程的执行。
其中，由于系统执行或者场景动画的配置需要多个线程的协同执行，且在复杂场景中，需要线程之间的相互唤醒通信来完成整体任务的执行，而线程之间的相互唤醒存在等待对方线程执行结果才能进行执行处理的情况。而针对第一线程的执行依赖于第二线程的执行结果时，可以将第二线程的优先级进行调整，例如提升第二线程的优先级，提升开始执行的时间点，提升系统的执行效率，避免出现阻塞、卡顿等现象。
其中，在本申请实施例中，当第一线程的执行依赖于第二线程的执行结果时，在第二线程执行过程中，可以将第一线程设置为等待状态，即，可选的，在本申请的一些实施例中，步骤“根据所述执行结果进行所述第一线程的执行”，包括：
当所述第二线程根据所述目标优先级执行时，将所述第一线程设置为等待状态；
当所述第一线程接收到所述执行结果时，根据所述执行结果将所述第一线程调整为运行状态。
其中，等待状态可以包括休眠状态，当第一线程的执行依赖于第二线程的执行结果，且第二线程正在执行时，可以将第一线程设置为等待状态；当第二线程执行结束后，可以将第一线程的执行状态调整为运行状态，根据第二线程的执行结果对第一线程进行执行。
其中，在本申请实施例中，还可以根据唤醒次数来确定是否需要对第二线程进行优先级的重新确定，即，可选的，在本申请的一些实施例中，步骤“根据所述第一线程的当前优先级，确定目标优先级”，包括：
记录所述第一线程唤醒所述第二线程、且所述第二线程在预设时间阈值内唤醒所述第一线程的次数，得到行为次数；
当所述行为次数大于预设数量阈值后，根据所述第一线程的当前优先级确定目标优先级。
其中，第一线程唤醒第二线程且第二线程在预设时间阈值内又唤醒了第一线程，说明了第一线程与第二线程之间存在相互唤醒通信的情况，例如，第二线程将执行结果传递给了第一线程。基于此，可以根据第一线程的优先级对第二线程的优先级进行调整，以加快第二线程的执行。
其中，在本申请实施例中，目标优先级高于或者等于第二线程在系统配置中的原始优先级，其中，原始优先级是线程原始携带的普通优先级。其中，通过提升第二线程的优先级，加快第二线程的执行，使得第一线程和第二线程对应的系统任务能够尽快执行和完成。
其中，在本申请实施例中，可以将第一线程的当前优先级直接作为第二线程的目标优先级，即，可选的，在本申请的一些实施例中，步骤“根据所述第一线程的当前优先级，确定目标优先级”，包括：
直接将所述当前优先级作为目标优先级。
其中，通过将第二线程调整为与第一线程相同的优先级，使得第二线程拥有与第一线程相同的调度资源，使得第二线程能够与第一线程协同快速执行，解决线程优先级翻转问题（低优先级数据无法得到足够的调度导致高优先级线程等待共享数据时延过长）。
其中，在本申请实施例中，还可以根据当前优先级与目标优先级的映射关系来确定第二线程的目标优先级，即，可选的，在本申请的一些实施例中，步骤“根据所述第一线程的当前优先级，确定目标优先级”，包括：
获取映射关系集合，所述映射关系集合包括预设当前优先级与预设目标优先级的映射关系；
根据所述映射关系，确定所述第一线程的当前优先级对应的目标优先级。
其中，该映射关系集合可以预先根据实际需要或者经验参数进行建立，其中，根据映射关系集合，可以快速定位第二线程所需的目标优先级。
其中，在本申请实施例中，对优先级的调整可以通过对相应的优先级参数进行调整来实现，例如，优先级参数区间为[-20，19]，其中优先级参数-20对应最高优先级，优先级参数19对应最低优先级，可以调整优先级参数来调整线程的优先级。
其中，在本申请实施例中，在第二线程根据目标优先级执行后，可以将第二线程的优先级进行恢复，以保证第二线程再被其他线程唤醒时能够保证系统执行稳定性，即，可选的，在本申请实施例中，步骤“根据所述目标优先级执行所述第二线程”之后，该方法还包括：
将第二线程的优先级由目标优先级调整为系统配置中的原始优先级。
其中，在本申请实施例中，在检测到第一线程唤醒第二线程时，根据第一线程的当前优先级确定目标优先级，并将目标优先级传递给第二线程，使得第二线程能够根据目标优先级进行执行，其中，通过对被唤醒通信的线程的优先级的调整，可在提升被唤醒的线程的优先级后，实现被唤醒线程的优先执行，提升执行效率。同时，当第一线程的执行依赖于第二线程的执行结果时，在实现第二线程的优先执行后，还可以提升第一线程的执行效率，避免第一线程长时间处理等待或者休眠状态，提升系统（安卓系统不同优先级线程之间的异步调用）整体执行效率。解决不同优先级线程之间异步调用时由于异步线程（第二线程）优先级低被抢占，阻塞主关键线程（第一线程）运行。
其中，由于第二线程（如子线程）在执行过程中容易因资源调度情况不够（如可调度资源被占用）而处于等待状态，进一步使得第一线程不能及时获取第二线程的反馈，使得第一线程出现阻塞，影响系统执行效率，例如，请参阅图3，图3是本申请实施例提供的第一线程被第二线程阻塞的场景示意图，具体如下：
第一线程在运行过程中通过调用函数（handler）发送信息（message）唤醒第二线程后，由于第一线程需等待第二线程的执行结果才能进行后续的执行，因此，在第二线程执行过程中第一线程处于等待状态（休眠状态）；
第二线程在被第一线程唤醒后开始执行，但是由于第二线程的优先级较低，需等待其他与当前任务无关的线程执行完成后才能执行，因此，第二线程存在一段时间较长的待运行状态，并在无关线程释放资源后才继续执行；
第二线程重新执行后调用函数（handler）发送信息（message）唤醒第一线程后结束运行；
第一线程根据第二线程的执行结果进行后续的执行，完成系统任务。
其中，由于第一线程与第二线程之间存在相互唤醒的情况，例如，第一线程的执行依赖于第二线程的执行结果，因此，当第二线程的执行存在等待延迟时，影响第一线程的执行，因此，本申请实施例可以对第二线程的执行优先级进行调整，以加快第二线程的执行，减少第一线程的执行等待时间。
例如，请参阅图3，第一线程运行时调用handler发送message给第二线程，第二线程收到message后开始运行，第一线程发送完message后进入等待状态，即等待第二线程返回message才可进行下一步操作，直到第二线程运行结束返回message才继续运行。若不传染优先级参数给第二线程，则第二线程由于分配的时间片少、优先级参数低，使得调度资源被无关线程抢占，影响第二线程的执行，进而阻塞第一线程运行，降低系统执行效率。
请参阅图4，图4是本申请实施例提供的对唤醒行为进行记录的流程示意图，具体如下：
对线程进行识别，确定第一线程（识别关键线程）；
判断第一线程是否调用函数（handler）向第二线程发送信息（message），如果是，则执行步骤123，如果否，则执行步骤129；
判断第二线程的运行是否超时，如果否，则执行步骤124，如果是，则执行步骤129；
在第二线程运行结束后，判断第二线程是否直接进行休眠模式，如果否，则执行步骤125，如果是，则执行步骤129；
判断第二线程是否通过函数（handler）向第一线程返回信息（message），如果是，则执行步骤126，如果否，则执行步骤129；
记录唤醒且返回的次数（行为次数或关系记录次数），得到线程对关系记录；
判断线程对关系记录中关系记录次数是否大于预设数量阈值，如果是，则执行步骤128，如果否，则执行步骤129；
记录第一线程与第二线程关系对（根据第一线程和第二线程的id建立关系对）；
结束。
其中，第一线程唤醒第二线程且第二线程在预设时间阈值内又唤醒第一线程的行为表明第一线程与第二线程之间存在协同关系，例如，第一线程的执行可能依赖于第二线程的执行结果。
其中，在本申请实施例中，为提高优先级调整的准确性，在行为次数超过预设数量阈值后才进行优先级参数的调整，使得能够在满足预设数量阈值后，进行优先级参数的传递，调整第二线程的优先级，加快第二线程的开始执行时间。
其中，在本申请实施例中，可以将唤醒行为记录在调用关系管理列表中，在后续线程唤醒后，根据关系管理列表进行优先级参数的传递，例如，通过收集线程之间的异步调用特征，如异步调用行为记录模块记录高优先级线程异步唤醒了低优先级线程，同时低优先级线程经过一段时间后又异步唤醒了高优先级线程的行为，行为次数超过了预先设置好的次数时，则认为该异步调用需要传染线程优先级（高优先级线程的优先级参数传染到低优先级线程中），根据记录次数生成调用关系管理列表，应用重新启动运行且发生异步调用关系时，同时查询该调用关系管理列表，决定是否传递优先级参数。
例如，请参阅图5，图5是本申请实施例提供的优先级参数传递流程示意图，具体如下：
对线程进行识别，确定第一线程（识别关键线程）；
判断第一线程是否唤醒第二线程，且第一线程处于等待状态，如果是，则执行步骤132，如果否，则执行步骤136；
判断第二线程是否在调用关系管理列表中，如果是，则执行步骤133，如果否，则执行步骤136；
传递目标优先级参数给第二线程（被唤醒线程），以使得第二线程能够根据优先级参数对应的优先级进行执行；
判断第二线程结束运行后是否通过函数（handler）返回信息（message），如果是，则执行步骤135，如果否，则执行步骤136；
恢复第二线程的优先级参数，将第二线程的优先级调整为系统配置的原始优先级（线程处理后优先级的恢复）；
结束。
其中，通过对第二线程的优先级的调整，加快了第二线程的执行，并在第二线程执行完成后对优先级的恢复，使得第二线程能够按照默认的优先级顺序进行线程执行，保证系统的稳定性。
为便于更好的实施本申请的线程执行方法，本申请还提供一种基于上述线程执行方法的线程执行装置。其中第三目标词语的含义与上述线程执行方法中相同，具体实现细节可以参考方法实施例中的说明。
请参阅图6，图6为本申请提供的线程执行装置的结构示意图，其中，该线程执行装置可以包括：
确定模块201，用于当检测到第一线程唤醒第二线程时，根据所述第一线程的当前优先级，确定目标优先级。

其中，在本申请的一些实施例中，该装置还包括返回执行模块，返回执行模块包括：

执行单元，用于根据所述执行结果进行所述第一线程的执行。
其中，在本申请的一些实施例中，执行单元包括：
等待子单元，用于当所述第二线程根据所述目标优先级执行时，将所述第一线程设置为等待状态；

其中，在本申请的一些实施例中，确定模块201包括：

其中，在本申请的一些实施例中，目标优先级高于或等于所述第二线程在系统配置中的原始优先级。

其中，本申请实施例在检测到第一线程唤醒第二线程时，根据第一线程的当前优先级确定目标优先级，并将目标优先级传递给第二线程，使得第二线程能够根据目标优先级进行执行，其中，通过对被唤醒通信的线程的优先级的调整，可在提升被唤醒的线程的优先级后，实现被唤醒线程的优先执行，提升执行效率。同时，当第一线程的执行依赖于第二线程的执行结果时，在实现第二线程的优先执行后，还可以提升第一线程的执行效率，避免第一线程长时间处理等待或者休眠状态，提升系统整体执行效率。

    第一确定单元，用于当所述行为次数大于预设数量阈值后，根据所述第一线程的当前优先级确定目标优先级。
  13. 根据权利要求9所述的装置，其中，所述第一确定单元具体用于：
    目标优先级高于或等于所述第二线程在系统配置中的原始优先级。
  14. 根据权利要求9所述的装置，其中，所述确定模块包括：
    第二确定单元，用于直接将所述当前优先级作为目标优先级。
  15. 根据权利要求9所述的装置，其中，所述确定模块包括：
    获取单元，用于获取映射关系集合，所述映射关系集合包括预设当前优先级与预设目标优先级的映射关系；
    第三确定单元，用于根据所述映射关系，确定所述第一线程的当前优先级对应的目标优先级。
  16. 根据权利要求9所述的装置，其中，执行模块还包括：
    调整单元，用于将第二线程的优先级由目标优先级调整为系统配置中的原始优先级。
  17. 一种电子设备，其中，所述电子设备包括存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，其中，所述处理器执行所述计算机程序时实现：
    当检测到第一线程唤醒第二线程时，根据所述第一线程的当前优先级，确定目标优先级；
    将所述目标优先级传递给所述第二线程，并根据所述目标优先级执行所述第二线程。
  18. 根据权利要求17所述的一种电子设备，其中，所述处理器执行所述计算机程序时还实现：
    基于所述唤醒，将所述第二线程的执行结果返回给所述第一线程，其中，所述执行结果是所述第二线程根据所述目标优先级执行后得到的；
    根据所述执行结果进行所述第一线程的执行。
  19. 一种计算机可读存储介质，其中，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现：
    当检测到第一线程唤醒第二线程时，根据所述第一线程的当前优先级，确定目标优先级；
    将所述目标优先级传递给所述第二线程，并根据所述目标优先级执行所述第二线程。
  20. 根据权利要求19所述的一种计算机可读存储介质，其中，所述计算机程序被处理器执行时还实现：
    基于所述唤醒，将所述第二线程的执行结果返回给所述第一线程，其中，所述执行结果是所述第二线程根据所述目标优先级执行后得到的；
    根据所述执行结果进行所述第一线程的执行。
