我面临一个问题，即我的简单 AGI 应用程序在保存/更新实体时挂起，并且没有抛出任何错误。从存储库中选择查询/方法按预期工作，没有任何错误。我将 Spring Boot 与 Spring Data JPA 结合使用，该 JPA 持久保存到 MYSQL 数据库。
订阅者.java:
package com.newcom.ncivr.model;
import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import javax.persistence.*;
@Entity @Table(name = "subscribers")
public class Subscriber{
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private int Id;
private String msisdn;
private String subscriptionName;
@Column(columnDefinition = "DATETIME")
private DateTime lastRenewal;
private String status;
public Subscriber() {
}
public Subscriber(String msisdn, String subscriptionName) {
this.msisdn = msisdn;
this.subscriptionName = subscriptionName;
this.lastRenewal = DateTime.now(DateTimeZone.UTC).minusDays(1);
this.status = "ACTIVE";
}
//POJO Getters and Setters Excluded from Sample
}
SubscriberRepository.java:
package com.newcom.ncivr.repository;
import com.newcom.ncivr.model.Subscriber;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface SubscriberRepository extends CrudRepository<Subscriber,Integer>{
Subscriber findFirstByMsisdnAndSubscriptionNameAndStatus(String msisdn, String subscriptionName, String status);
}
IvrAgi.java:

public class IvrAgi extends BaseAgiScript {
private Logger log = LoggerFactory.getLogger(IvrAgi.class);
@Autowired
SubscriberRepository subscriberRepository;
public void service(AgiRequest request, AgiChannel channel) throws AgiException {
log.info("********** Agi Script Started. **************");
// Answer the channel...
answer();
log.info("Caller ID: "+request.getCallerIdNumber());
mainMenu(request);
log.info("********** Agi Script Completed. **************");
}
public void mainMenu(AgiRequest request) throws AgiException {
try {
while (true) {
String data = getData("ivr_main_menu");
log.info("User Input : " + data);
if (data.equals("1")) {
System.out.println(request.getCallerIdNumber() + ": User Selected 1");
streamFile("ivr_opt_one");
log.info(request.getCallerIdNumber() + ": User Selected 1");
try {
Subscriber subscriber = subscriberRepository.findFirstByMsisdnAndSubscriptionNameAndStatus(request.getCallerIdNumber(),"NEWS", "ACTIVE");
if(subscriber != null){
log.info("Id --->" + subscriber.toString());
subscriber.setLastRenewal(DateTime.now(DateTimeZone.UTC));
subscriber = subscriberRepository.save(subscriber);
log.info("Updated Entity --> " + subscriber.toString());
}else{
log.info("User is NOT Subscribed to NEWS");
}
}catch (Exception e){
e.printStackTrace();
}
hangup();
}else{
continue;
}
}
} catch (Throwable e) {
e.printStackTrace();
}
}
}

最佳答案
我将相关的堆栈跟踪信息放在下面的转储中。
有一个线程被阻塞并且正在等待锁定<0x0000000081cc7448>。如果您搜索线程转储，您会在下面包含的另一个线程中找到第二次提及 0000000081cc7448。
该线程名为restartedMain，它似乎与启动开发工具相关，该工具监视文件并在文件更改时重新启动应用程序。例如，参见问题 SpringBoot app starts multiple times and disconnects from logstash和评论。
我建议您删除/禁用开发工具，因为它们似乎与问题有关。

更新
从你的新线程转储来看，如果没有启动开发工具的帮助，这个 AGI 东西就会陷入麻烦。阻塞线程看起来与上面发布的非常相似。它正在尝试通过调用 DefaultAgiServer.startup 连接到某个服务器。不确定那里出了什么问题，但也许它会产生一些日志，或者在很长一段时间后失败并出现有意义的完整错误，或者您可以调试它？也许只是连接信息错误？
我找到了这个link当谷歌搜索方法调用时。
关于java - 实体 save() 方法挂起且没有错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47562447/
