实现要求：
在图书管理系统中，学生管理模块、书籍管理模块和借还书管理模块等其他模块，相互配合协作，促使系统的运行流畅。定义三个模块，使用<import>标签完成分模块配置开发，模拟实现学生借书和还书的过程，将结束输出到控制台。
要求如下：
- 定义学生管理模块、书籍管理模块和借还书管理模块。
- 使用<import>标签完成分模块配置开发
实现步骤：
在com.zn.demo.student包下创建Student类，添加stuId属性和stuName属性
package com.zn.mhys.demo.student; public class Student { private String stuId; private String stuName; public String getStuId() { return stuId; } public void setStuId(String stuId) { this.stuId = stuId; } public String getStuName() { return stuName; } public void setStuName(String stuName) { this.stuName = stuName; } }
在com.zn.demo.student包下创建applicationContext-student.xml配置文件，注册Student类到容器
<?xml version="1.0" encoding="UTF-8"?> <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-4.2.xsd "> <bean id="student" class="com.zn.mhys.demo.student.Student"></bean> </beans>
在com.zn.demo.book包下创建Book类，添加bookId属性和bookName属性
package com.zn.mhys.demo.book; public class Book { private String bookId; private String bookName; public String getBookId() { return bookId; } public void setBookId(String bookId) { this.bookId = bookId; } public String getBookName() { return bookName; } public void setBookName(String bookName) { this.bookName = bookName; } }
在com.zn.demo.book包下创建applicationContext-book.xml配置文件，注册Book类到容器。
<?xml version="1.0" encoding="UTF-8"?> <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-4.2.xsd "> <bean id="book" class="com.zn.mhys.demo.book.Book"></bean> </beans>
在com.zn.demo.service包下创建BorrowAndReturnService类，声明borrowBook()方法和returnBook()方法
package com.zn.mhys.demo.service; import com.zn.mhys.demo.book.Book; import com.zn.mhys.demo.student.Student; public class BorrowAndReturnService { public void borrowBook(Student student,Book book){ System.out.println("学生编号："+student.getStuId()+"，学生姓名："+student.getStuName() +"，借阅书名："+book.getBookName()+"，编号："+book.getBookId()+"的书名"); } public void returnBook(Student student,Book book){ System.out.println("学生编号："+student.getStuId()+"，学生姓名："+student.getStuName() +"，归还书名："+book.getBookName()+"，编号："+book.getBookId()+"的书名"); } }
在com.zn.demo.service包下创建applicationContext-service.xml配置文件，注册BorrowAndReturnService类到容器
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd "> <!-- 2.1.4 --> <import resource="com/zn/mhys/demo/book/applicationContext-book.xml"/> <import resource="com/zn/mhys/demo/student/applicationContext-student.xml"/> <import resource="com/zn/mhys/demo/service/applicationContext-service.xml"/> </beans>
在src目录下创建applicationContext.xml配置文件，引入3个模块的配置文件 在com.zn.demo.test包下创建Test测试类
package com.zn.mhys.demo.test; import java.sql.Connection; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.springframework.core.io.ClassPathResource; import com.zn.mhys.demo.book.Book; import com.zn.mhys.demo.service.BorrowAndReturnService; import com.zn.mhys.demo.service.JdbcService; import com.zn.mhys.demo.student.Student; public class Test { public static void main(String[] args) { ClassPathResource resource = new ClassPathResource("applicationContext.xml"); XmlBeanFactory context = new XmlBeanFactory(resource); // 2.1.4 Student student = (Student)context.getBean("student"); student.setStuId("003"); student.setStuName("杨明金"); Book book = (Book)context.getBean("book"); book.setBookId("130006"); book.setBookName("spring企业级开发"); BorrowAndReturnService bars = (BorrowAndReturnService) context.getBean("service"); bars.borrowBook(student, book); bars.returnBook(student, book); } }
