Spring actual method example of setting common attribute values

This article describes the method of setting common attribute values in spring. Share with you for your reference, as follows:

One configuration

<?xml version="1.0" encoding="GBK"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns="http://www.springframework.org/schema/beans"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
   <bean id="exampleBean" class="org.crazyit.app.service.ExampleBean">
      <!-- 指定int型的参数值 -->
      <property name="integerField" value="1"/>
      <!-- 指定double型的参数值 -->
      <property name="doubleField" value="2.3"/>
   </bean>
</beans>

Second bean

package org.crazyit.app.service;
public class ExampleBean
{
   // 定义一个int型的成员变量
   private int integerField;
   // 定义一个double型的成员变量
   private double doubleField;
   // integerField的setter和getter方法
   public void setIntegerField(int integerField)
   {
      this.integerField = integerField;
   }
   public int getIntegerField()
   {
      return this.integerField;
   }
   // doubleField的setter和getter方法
   public void setDoubleField(double doubleField)
   {
      this.doubleField = doubleField;
   }
   public double getDoubleField()
   {
      return this.doubleField;
   }
}

Three test categories

package lee;
import org.springframework.context.*;
import org.springframework.context.support.*;
import org.crazyit.app.service.*;
public class BeanTest
{
  public static void main(String[] args)
  {
    //以类加载路径下的bean.xml文件来创建spring容器
    ApplicationContext ctx = new
      ClassPathXmlApplicationContext("beans.xml");
    ExampleBean b = ctx.getBean("exampleBean",ExampleBean.class);
    System.out.println(b.getIntegerField());
    System.out.println(b.getDoubleField());
  }
}
