1. 通過引入p名稱空間完成屬性的注入

1.1. 普通屬性: p:屬性名="值"。

1.2. 對象屬性: p:屬性名-ref="值"。

2. P名稱空間的引入

3. 使用p名稱空間

4. p標(biāo)簽實例

4.1. 新建一個名為SpringDI_P的Java工程, 拷入Spring相關(guān)包

4.2. 創(chuàng)建Teacher.java

package com.lywgames.bean;public class Teacher {private int id;private String name;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}@Overridepublic String toString() {return "Teacher [id=" + id + ", name=" + name + "]";}}

4.3. 創(chuàng)建Clazz.java

package com.lywgames.bean;public class Clazz {private Teacher teacher;public Teacher getTeacher() {return teacher;}public void setTeacher(Teacher teacher) {this.teacher = teacher;}@Overridepublic String toString() {return "Clazz [teacher=" + teacher + "]";}}

4.4. 創(chuàng)建Test.java

package com.lywgames;import org.springframework.context.support.ClassPathXmlApplicationContext; import com.lywgames.bean.Clazz; import com.lywgames.bean.Teacher;public class Test {public static void main(String[] args) {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");System.out.println(context.getBean(Teacher.class).toString());System.out.println(context.getBean(Clazz.class).toString());context.close();} }

4.5. 在src目錄下創(chuàng)建applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:p="http://www.springframework.org/schema/p"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.xsd"><bean id="teacher" class="com.lywgames.bean.Teacher" p:id="901" p:name="xiaocui"/> <bean id="clazz" class="com.lywgames.bean.Clazz" p:teacher-ref="teacher"/> </beans>

4.6. 運行項目
