xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>1.0.0</modelVersion><groupId>shequ</groupId><artifactId>springdemo13</artifactId><version>0.0.1-SNAPSHOT</version><properties><java.version>1.7</java.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding></properties><repositories><repository><id>codelds</id><url>https://code.lds.org/nexus/content/groups/main-repo</url></repository></repositories><dependencies><dependency><groupId>javax.annotation</groupId><artifactId>jsr250-api</artifactId><version>1.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.10</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.1.4.RELEASE</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.34</version></dependency></dependencies><build/>
</project>

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;}@Autowiredpublic 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/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/utilhttp://www.springframework.org/schema/util/spring-util-4.0.xsdhttp://www.springframework.org/schema/contexthttp://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
