devo aggiungere queste librerie:

• commons-logging-1.1.3
• primavera-AOP-4.0.0. M1
• molla-aspetti-4.0.0.M1
• molla-fagioli-4.0.0.M1
• molla conte xt-4.0.0.M1
• molla context-supporto-4.0.0.M1
• molla-core-4.0.0.M1
• antlr-runtime-3.0.1

My codice:

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(); 
    } 
} 

configurazione

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

Answer 1

Cercate di non dividere questi XML in più Linee:

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

Spesso a capo e spazi bianchi all'interno XML valori degli attributi vengono trattati come letterale. Usare questo invece:

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

Answer 2

Basta aggiungere spring-expression-3.x.x.RELEASE vaso attraverso java percorso di generazione

Answer 3

ho ottenuto lo stesso errore, corretto che la prima linea dovrebbe beans.xml dovrebbe iniziare con (nessuna linea vuota nella prima riga)

Answer 4

ho avuto lo stesso problema. Non ci dovrebbe essere alcun spazio all'inizio della prima linea di cioè questa è la linea

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