JSF Tutorial - JSF JSF_Spring Example

The following code shows how to use Spring to work with JSF.

Example

The following code is from PrinterImpl.java.

package com.java2s.common;

import javax.inject.Named;


@Named
public class PrinterImpl implements Printer{
 
  public String print() {
    
    return "JSF 2 + Spring Integration";
  
  }
 
}

The following code is from Printer.java.

package com.java2s.common;

public interface Printer{
 
  public String print();
 
}

The following code is from default.xhtml.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"   
      xmlns:h="http://java.sun.com/jsf/html">
 
<h:body>#{userBean.printMsgFromSpring()}</h:body>
 
</html>

The following code is from UserBean.java.

package com.java2s.common;

import javax.inject.Inject;
import javax.inject.Named;
import org.springframework.context.annotation.Scope;

@Named
@Scope("session")
public class UserBean {

  @Inject
  Printer printer;

  public void setPrinter(Printer p) {
    this.printer = p;
  }

  public String printMsgFromSpring() {
    return printer.print();
  }

}
