c命名空间与p命名空间

c:construct 构造器注入
p:property 属性注入

c命名空间注入和p命名空间注入都属于第三方注入，需要引入xml依赖

xmlns:p="http://www.springframework.org/schema/p"
xmlns:c="http://www.springframework.org/schema/c"

案例:
1.创建pojo类

package com.web.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Teacher {
    private String name;
    private int age;
    private Address address;
}

2.创建applicationContext.xml

<?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:p="http://www.springframework.org/schema/p"
       xmlns:c="http://www.springframework.org/schema/c"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <!-- p命名空间   -->
    <bean id="address" class="com.web.pojo.Address" p:address="西安"/>
    <bean id="teacher1" class="com.web.pojo.Teacher" p:name="alis" p:age="23" p:address-ref="address"/>
    <!-- c命名空间   -->
    <bean id="teacher2" class="com.web.pojo.Teacher" c:name="sim" c:age="21" c:address-ref="address"/>
</beans>

3.测试

package com.web.test;

import com.web.pojo.Teacher;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.testng.annotations.Test;

public class TestTeacher {
    @Test
    public void testTeacher1(){
        ApplicationContext context=new ClassPathXmlApplicationContext("Teacher.xml");
        Teacher bean = context.getBean("teacher1",Teacher.class);
        System.out.println(bean);
    }
    @Test
    public void testTeacher2(){
        ApplicationContext context=new ClassPathXmlApplicationContext("Teacher.xml");
        Teacher bean = context.getBean("teacher2",Teacher.class);
        System.out.println(bean);
    }
}

Teacher(name=alis, age=23, address=Address(address=西安))
Teacher(name=sim, age=21, address=Address(address=西安))
