java - 线程中的Spring异常 "main"java.lang.NoSuchMethodError : org. springframework.util.ReflectionUtils.clearCache()V

Question

我是 Spring 新手，我正在尝试使用 Spring 容器构造对象，该容器将解析我的 XML 文件，所以我有一个 .xml 和两个 .java类。

Spring版本5.1.0

我正在寻找类似的解决方案，但有些是 Maven 解决方案，不适用于 Spring。

1. employeeBeanFile.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context.xsd">
   
   <bean id="emp" class="co.bin.rito.Employee">
       <property name="eid" value="143529" />
       <property name="ename" value="Rito Sarkar" />
       <property name="eaddress" value="Tower Two Magarpatta, S5-458" />
   </bean>
   

2. Employee.java

   public class Employee {
       // this contains attributes 
       // constructor and methods
       // and set, get and toString() function 
   }
   

3. Client.java

   import org.springframework.context.ApplicationContext;
   import org.springframework.context.support.AbstractApplicationContext;
   import org.springframework.context.support.ClassPathXmlApplicationContext;
   
   public class Client {
   
       public static void main(String[] args) {
           // Spring way | IOC (Inversion of control)
           ApplicationContext context = new ClassPathXmlApplicationContext("employeeBeanFile.xml");
           Employee e = (Employee) context.getBean("emp");
           System.out.println("Employee one details: " + e);
           ((AbstractApplicationContext) context).close();
       }}
   

使用此代码我收到以下错误

Exception in thread "main" java.lang.NoSuchMethodError: org.springframework.util.ReflectionUtils.clearCache()V
    at org.springframework.context.support.AbstractApplicationContext.resetCommonCaches(AbstractApplicationContext.java:910)
    at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:573)
    at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:144)
    at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:85)
    at co.bin.rito.Client.main(Client.java:11)

出现此错误是由于 Spring 中的 jar 版本不同。请在您的 pom 中使用正确的 jar 依赖项。还要确保您的构建路径中没有包含其他版本的 jar。
