我添加了这些库:

  • 公共日志记录-1.1.3
  • 弹簧-aop-4.0.0.M1
  • 弹簧方面-4.0.0.M1
  • spring-beans-4.0.0.M1
  • 弹簧上下文4.0.0.M1
  • spring-context-support-4.0.0.M1
  • 弹簧芯4.0.0.M1
  • antlr-runtime-3.0.1

我的代码:

package com.tutorialspoint;

public class HelloWorld {
    private String message;

    public void setMessage(String message){
        this.message  = message;
    }

    public void getMessage(){
        System.out.println("Your Message : " + message);
    }
}


package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainApp {
    @SuppressWarnings("resource")
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");

        HelloWorld obj = (HelloWorld) context.getBean("helloWorld");

        obj.getMessage();
    }
}

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

 3.0.xsd"

    <bean id="helloWorld" class="com.tutorialspoint.HelloWorld">
        <property name="message" value="Hello World!" />
    </bean>
</beans>

尽量不要将这些 xml 拆分为多行:

xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-
 3.0.xsd"

XML 属性值中的换行符和空格通常被视为文字。改用这个:

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"

我有同样的问题。第一行的开头不应有任何空格,即这是行

no space<?xml version="1.0" encoding="UTF-8"?>

我得到了同样的错误,更正了第一行应该以 Beans.xml 开头(第一行中没有空行)

只需spring-expression-3.x.x.RELEASE通过java构建路径添加jar
