我是春天的新手，我正在尝试使用 Spring Container 构造对象，该对象将解析我的 XML 文件，所以我有一个.xml和两个.java类。

春季版 5.1.0

我正在寻找类似的解决方案，但有些是不适合春季的 Maven 解决方案。

  1. 员工BeanFile.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. 雇员.java

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

  3. 客户端.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，我得到以下错误

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)

由于 Spring 中不同版本的 jars 会发生此错误。请在您的 pom 中使用正确的 jars 依赖项。还要确保在构建路径中没有包含其他版本的 jar。
