3.在src/main/java下创建实体Bean Customer,包名(com.mycompany.shequ.bean)如图所示
4.实体Bean Customer的内容如下
package com.mycompany.shequ.bean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component("customerBean")
public class Customer {
private String name;
private String email;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
@Value("#{('dengyunshuo@163.com' matches '^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)" +
"*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$') ? 'dengyunshuo@163.com':'不合法'}")
public void setEmail(String email) {
this.email = email;
}
}
5.在src/main/java下创建dao ICustomerDao,包名(com.mycompany.shequ.dao)如图所示
6.ICustomerDao的内容如下
package com.mycompany.shequ.dao;
public interface ICustomerDao {
public void showMe();
}
7.在src/main/java下创建ICustomerDao的实现类CustomerDaoImpl,包名(com.mycompany.shequ.dao.impl)如图所示
8.ICustomerDao的实现类CustomerDaoImpl的内容如下
package com.mycompany.shequ.dao.impl;
import com.mycompany.shequ.dao.ICustomerDao;
public class CustomerDaoImpl implements ICustomerDao {
public void showMe() {
System.out.println("I'm CustomerDaoImpl");
}
}
9.在src/main/java下创建业务Bean ICustomerService接口,包名(com.mycompany.shequ.service)如图所示
10.ICustomerService接口的内容如下
package com.mycompany.shequ.service;
public interface ICustomerService {
public void showMe();
}
11.在src/main/java下创建业务Bean ICustomerService接口的实现类CustomerServiceImpl,包名(com.mycompany.shequ.service.impl)如图所示
12.业务Bean ICustomerService接口的实现类CustomerServiceImpl的内容如下
package com.mycompany.shequ.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import com.mycompany.shequ.dao.ICustomerDao;
import com.mycompany.shequ.service.ICustomerService;
public class CustomerServiceImpl implements ICustomerService {
private ICustomerDao customerDao;
public ICustomerDao getCustomerDao() {
return customerDao;
}
@Autowired
public void setCustomerDao(ICustomerDao customerDao) {
this.customerDao = customerDao;
}
public void showMe() {
customerDao.showMe();
}
}
13.在src/main/resource下创建核心的配置文件applicationContext.xml,如图所示
14.配置文件applicationContext.xml,如图所示
<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:context="http://www.springframework.org/schema/context"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<context:component-scan base-package="com.mycompany.shequ">
<context:include-filter type="regex" expression="com.mycompany.shequ.dao.impl.*Impl"/>
<context:include-filter type="regex" expression="com.mycompany.shequ.service.impl.*Impl"/>
</context:component-scan>
</beans>
15.在src/test/java下创建测试文件AppTest,包名(com.mycompany.shequ.test)如图所示
16.测试文件AppTest的内容如下
package com.mycompany.shequ.test;
import org.junit.Test;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.mycompany.shequ.service.ICustomerService;
public class AppTest {
@Test
public void beanTest(){
ConfigurableApplicationContext context = new
ClassPathXmlApplicationContext("applicationContext.xml");
ICustomerService customerService = (ICustomerService) context.getBean("customerServiceImpl");
customerService.showMe();
}
}
17.在测试类AppTest的beanTest方法上右键运行,输出结果如图所示
