过程

今天在给程序打包后，使用如下命令执行后，出现这个错误

java -jar xxxx.jar

原因

看报错信息因为 atomikos 是缺少Jar包了，但没有指出是哪个包

No Assembler service found - please make sure that the right jars are in your classpath

然后看下面这段报错的位置，发现一个transaction包下的错误，这个时候就知道啥原因了。。。

org.springframework.transaction.jta.JtaTransactionManager.isExistingTransaction(JtaTransactionManager.java:824)

解决方法

引jar包啊！！！！
如果加了 atomikos-util 的依赖的话，把下面的依赖加进去就好

        <dependency>
            <groupId>com.atomikos</groupId>
            <artifactId>transactions</artifactId>
            <version>4.0.6</version>
        </dependency>
        <dependency>
            <groupId>com.atomikos</groupId>
            <artifactId>transactions-jta</artifactId>
            <version>4.0.6</version>
        </dependency>
        <dependency>
            <groupId>com.atomikos</groupId>
            <artifactId>transactions-jdbc</artifactId>

        </dependency>
        <dependency>

            <artifactId>transactions-api</artifactId>
