Spring references beans in different xml

Spring references beans in different xml

To reference the bean defined in the Spring-Common.xml in the Spring-Output.xml, you need to use Label. If it is referenced in the same xml file, use Label.

 package com.spring.output;public class OutputHelper {        IOutputGenerator outputGenerator;        public void generateOutput(){            this.outputGenerator.generateOutput();        }        public void setOutputGenerator(IOutputGenerator outputGenerator){            this.outputGenerator = outputGenerator;        }}

Spring-Output.xml

Spring-Common.xml

When calling the context method, write as follows:

 package com.spring.hello;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.spring.output.OutputHelper;public class App {    private static ApplicationContext context;    public static void main(String[] args)    {        context = new ClassPathXmlApplicationContext(new String[] {Spring-Common.xml,Spring-Output.xml});        OutputHelper output = (OutputHelper)context.getBean(OutputHelper);        output.generateOutput();    }}

CsvOutputGenerator. java

package com.spring.output.impl;import com.spring.output.IOutputGenerator;public class CsvOutputGenerator implements IOutputGenerator {    public void generateOutput() {        System.out.println(Creating CsvOutputGenerator  Output......);    }}

JsonOutputGenerator. java

 package com.spring.output.impl;import com.spring.output.IOutputGenerator;public class JsonOutputGenerator implements IOutputGenerator {    public void generateOutput() {   System.out.println(Creating JsonOutputGenerator output.......);    }}

IOutputGenerator. java

package com.spring.output;public interface IOutputGenerator {      public void generateOutput();}
