以下是Maven在本地回购协议中针对

atomikos

和s

Spring boot starter jta atomikos

的内容：

---

我从其他人那里继承了这个项目，所以我不确定为什么需要它，但是在Boot的

应用程序.java

旁边还有下面的额外类。应用程序中的任何东西似乎都不会直接调用它

package cwp.services;

import javax.transaction.TransactionManager;
import javax.transaction.UserTransaction;

import org.hibernate.engine.transaction.jta.platform.internal.AbstractJtaPlatform;

public class AtomikosJtaPlatform extends AbstractJtaPlatform {

    private static final long serialVersionUID = 1L;

    static TransactionManager transactionManager;
    static UserTransaction transaction;

    @Override
    protected TransactionManager locateTransactionManager() {
        return transactionManager;
    }

    @Override
    protected UserTransaction locateUserTransaction() {
        return transaction;
    }


    public static void setTransactionManager(TransactionManager transactionManager) {
        AtomikosJtaPlatform.transactionManager = transactionManager;
    }


    public static void setTransaction(UserTransaction transaction) {
        AtomikosJtaPlatform.transaction = transaction;
    }



}

这里还有一些似乎相关的摘录，摘自Spring Boot如何在错误发生之前解决其启动依赖关系的日志：

AtomikosJtaConfiguration:
      Did not match:
         - @ConditionalOnClass did not find required class 'com.atomikos.icatch.jta.UserTransactionManager' (OnClassCondition)

Spring Boot如何检测JTA环境

非常感谢任何关于如何解决此STS/Atomikos类加载问题的建议。

进一步检查后，我发现该项目的启动配置被错误配置，因为指向了另一个使用非XA数据源的项目：

---

把它指向当前的项目似乎已经解决了这个问题。

嗨，你能试着从本地maven repo中删除atomikos并重新启动吗？@guy对不起：那没用

AtomikosJtaConfiguration:
      Did not match:
         - @ConditionalOnClass did not find required class 'com.atomikos.icatch.jta.UserTransactionManager' (OnClassCondition)
