Spring Framework ClassPathXmlApplicationContext打包JAR后启动挂起问题

之前遇到过类似的Spring加载Bean定义卡死的问题，但对应的解决方案并不适用于当前场景。

环境信息 #

• Spring Framework 5.3.29
• OpenJDK 8

核心代码 #

System.out.println("Loading beans.xml from classpath");
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:beans.xml");
System.out.println("Loaded beans.xml from classpath.\nRunning helloWorld.");

beans.xml配置 #

<?xml version = "1.0" encoding = "UTF-8"?>

<beans xmlns = "http://www.springframework.org/schema/beans"
   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation = "http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans.xsd">

   <bean id = "helloWorld" class = "net.application.spring.HelloWorld">
      <property name = "message" value = "Hello World!"/>
   </bean>

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
        <property name="url" value="jdbc:sqlserver://blahblahblah" />
        <property name="username" value="some_user" />
        <property name="password" value="some_password" />
    </bean>

   <bean id = "exceptionDataDAO" class = "net.application.spring.ExceptionDataDAOImpl">
        <property name="dataSource" ref="dataSource" />
   </bean>

</beans>

问题现象 #

• 在VSCode中直接运行或调试时，程序运行完全正常
• 使用Maven命令 mvn clean compile assembly:single 打包成可执行JAR后，执行该JAR文件时，程序会卡在初始化ApplicationContext的代码行 ApplicationContext context = new ClassPathXmlApplicationContext("classpath:beans.xml");，无法继续执行后续逻辑
