Spring Exception in thread "main" java.lang.NoSuchMethodError： org.springframework.util.ReflectionUt

Question

我是spring的新手，我正试图使用spring Container构建对象，该容器将解析我的XML文件，因此我有一个.xml和两个.java类。

春季版本5.1.0

我在寻找类似的解决方案，但有些是专业的解决方案。

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();
   }}
   

有了这个代码，我得到了以下错误

Exception in thread "main" java.lang.NoSuchMethodError: org.springframework.util.ReflectionUtils.clearCache()V

此错误是由于Spring中不同版本的jar导致的。请在pom中使用正确的jars依赖项。还要确保您的构建路径中没有包含其他版本的jar。
