1.javabean

package com.bean; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component; @Component("user")
public class User {  //使用@Value註解賦預設值
 @Value("哈哈哈")
 private String username;
 @Value("123")
 private String password;
 
 public String getUsername() {
  return username;
 }
 public void setUsername(String username) {
  this.username = username;
 }
 public String getPassword() {
  return password;
 }
 public void setPassword(String password) {
  this.password = password;
 }
 public void show() {
  System.out.println("username="+username+","+"password="+password);
 }
}

2.配置檔案

<?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-4.3.xsd
  http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-4.3.xsd">
  <context:component-scan base-package="com.bean"></context:component-scan>
</beans>

3.測試類

package com.Test; import javax.faces.application.Application; import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Controller; import com.bean.User; public class test {
 @Test
 public void Controller(){
  ApplicationContext context=new ClassPathXmlApplicationContext("config.xml");
  User user=(User) context.getBean("user");
  user.show();
 }
}
