在spring中， 可以定义多个配置文件。
例子：
①首先定义一个班级类和一个学生类
1 package com.fuwh.spring;
2
3 public class Clazz {
4
5 private String name;
6 private int grade;
7
8 public int getGrade() {
9 return grade;
10 }
11 public void setGrade(int grade) {
12 this.grade = grade;
13 }
14 public Clazz() {
15 System.out.println("Clazz类被初始化");
16 // TODO Auto-generated constructor stub
17 }
18 public String getName() {
19 return name;
20 }
21 public void setName(String name) {
22 this.name = name;
23 }
24 @Override
25 public String toString() {
26 return "Student [name=" + name + ", grade=" + grade + "]";
27 }
28
29 }
1 package com.fuwh.spring;
2
3 public class Student {
4
5 private String name;
6 private int age;
7 private Clazz clazz;
8
9 public Clazz getClazz() {
10 return clazz;
11 }
12 public void setClazz(Clazz clazz) {
13 this.clazz = clazz;
14 }
15 public Student() {
16 System.out.println("Student类被初始化");
17 // TODO Auto-generated constructor stub
18 }
19 public String getName() {
20 return name;
21 }
22 public void setName(String name) {
23 this.name = name;
24 }
25 public int getAge() {
26 return age;
27 }
28 public void setAge(int age) {
29 this.age = age;
30 }
31 @Override
32 public String toString() {
33 return "Student [name=" + name + ", age=" + age + ",grade=" + clazz.getGrade()+clazz.getName() +"]";
34 }
35 }
② 定义两个配置文件，分别配置clazz（beanClazz）和student(studentClazz)
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"
3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4 xsi:schemaLocation="http://www.springframework.org/schema/beans
5 http://www.springframework.org/schema/beans/spring-beans.xsd">
6
7 <!-- services -->
8
9 <bean id="clazz" class="com.fuwh.spring.Clazz" lazy-init="default">
10 <property name="name" value="信息与计算科学"></property>
11 <property name="grade" value="08"></property>
12 </bean>
13
14 </beans>
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"
3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4 xsi:schemaLocation="http://www.springframework.org/schema/beans
5 http://www.springframework.org/schema/beans/spring-beans.xsd">
6
7 <!-- services -->
8
9 <bean id="student" class="com.fuwh.spring.Student" lazy-init="default">
10 <property name="name" value="fengzi"></property>
11 <property name="age" value="23"></property>
12 <property name="clazz" ref="clazz"></property>
13 </bean>
14
15 </beans>
③接下来测试一下，由于使用了多个配置文件的方式，所以在实例化applicationContext的时候，需要给ClassPathXmlApplicationContext传递一个配置文件的数组
1 package com.fuwh.spring;
2
3 import org.springframework.context.ApplicationContext;
4 import org.springframework.context.support.ClassPathXmlApplicationContext;
5
6 public class Spring01 {
7
8 public static void main(String[] args) {
9
10 // ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");
11 ApplicationContext ac=new ClassPathXmlApplicationContext(new String[]{"beanStudent.xml","beanClazz.xml"});
12 System.out.println(ac.getBean("student"));
13 }
14 }
★也可以在beanStudent.xml文件中，使用如下命令，将beanClazz.xml文件引入进来。这样在实例化ApplicationContext的时候，就只需要传入beanStudent.xml文件即可。
【<import resource="beanClazz.xml"/>】
Spring--多人开发
