Mina 在 Netbeans 上工作并在 fat-jar 中失败了？
Mina working on Netbeans and fails in a fat-jar?
奇怪的问题，如果我们创建一个 fat-jar 来执行项目而不是来自 Netbeans，它会失败。知道为什么吗？
这是一个简单的 apache-camel 应用程序，它使用 Mina 启动一个路由来接收 HL7，然后使用一个直接回答 ACK 消息的 bean，一个简单的示例。
<bean id="hl7codec" class="org.apache.camel.component.hl7.HL7MLLPCodec">
<property name="charset" value="utf-8"/>
</bean>
<bean id="answerACKHL7" class="com.mycompany.AnswerEMRBean" />
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route customId="true" id="routeID">
<from uri="mina:tcp://localhost:8255?sync=true&codec=#hl7codec" />
<bean ref="answerACKHL7" method="sendACK" />
</route>
</camelContext>
该应用程序有另一个 java 定义的 REST 路由，但这部分在 Netbeans 和执行 jar 文件中的工作方式相同。
如果我们 运行 它来自 Netbeans 并向它工作的端口发送 HL7 消息。好的，我们用 maven-shade-plugin 3.2.4 和 运行 用 java -jar jarfile.jar 构建一个 fat-jar 一切似乎开始正常然后我们发送相同的 HL7 消息如果 运行ning 从 netbeans 得到异常，则工作。

知道为什么构建 jar 失败了吗？？？
此致。
由于依赖于 fat jar 的阴影，您需要指示 maven 插件如何处理重复资源。在您的情况下， maven-shade-plugin 覆盖 TypeConverterLoader 负责类型转换，因此您得到
No type converter available to convert from type: java.lang.String to the required type 异常。
您需要配置 maven-shade-plugin 以合并此资源。见 How to create executable JAR for camel-main project:
