maven学习4 使用Maven构建Spring项目

1. 新建一个Web项目

参考之前的博客

2.修改 pom.xml，添加Spring依赖

1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
2. xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
3. <modelVersion>4.0.0</modelVersion>
4. <groupId>com.deppon.demo</groupId>
5. <artifactId>test04</artifactId>
6. <packaging>war</packaging>
7. <version>0.0.1-SNAPSHOT</version>
8. <name>test04 Maven Webapp</name>
9. <url>http://maven.apache.org</url>
10. <!-- 属性配置 -->
11. <properties>
12. <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
13. </properties>
14. <dependencies>
15. <dependency>
16. <groupId>junit</groupId>
17. <artifactId>junit</artifactId>
18. <version>4.10</version>
19. <scope>test</scope>
20. </dependency>
21. <!-- 添加Spring依赖 -->
22. <dependency>
23. <groupId>org.springframework</groupId>
24. <artifactId>spring-core</artifactId>
25. <version>3.1.1.RELEASE</version>
26. </dependency>
27. <dependency>
28. <groupId>org.springframework</groupId>
29. <artifactId>spring-beans</artifactId>
30. <version>3.1.1.RELEASE</version>
31. </dependency>
32. <dependency>
33. <groupId>org.springframework</groupId>
34. <artifactId>spring-context</artifactId>
35. <version>3.1.1.RELEASE</version>
36. </dependency>
37. <dependency>
38. <groupId>org.springframework</groupId>
39. <artifactId>spring-jdbc</artifactId>
40. <version>3.1.1.RELEASE</version>
41. </dependency>
42. </dependencies>
43. <build>
44. <finalName>test04</finalName>
45. </build>
46. </project>

3.添加Spring配置文件，applicationContext.xml

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" xmlns:aop="http://www.springframework.org/schema/aop"
4. xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
5. xsi:schemaLocation="
6. http://www.springframework.org/schema/beans
7. http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
8. http://www.springframework.org/schema/tx
9. http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
10. http://www.springframework.org/schema/aop
11. http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
12. http://www.springframework.org/schema/context
13. http://www.springframework.org/schema/context/spring-context-3.0.xsd">
14. <bean id="personDao" class="com.deppon.test04.dao.impl.PersonDao"></bean>
15. <bean id="personService" class="com.deppon.test04.service.impl.PersonService">
16. <property name="personDao" ref="personDao"></property>
17. </bean>
18. </beans>

IPersonDao.java

1. package com.deppon.test04.dao;
2. public interface IPersonDao {
3. public void save();
4. }

PersonDao.java

1. package com.deppon.test04.dao.impl;
2. import com.deppon.test04.dao.IPersonDao;
3. public class PersonDao implements IPersonDao {
4. @Override
5. public void save() {
6. System.out.println("------------from PersonDao.save()");
7. }
8. }

IPersonService.Java

1. package com.deppon.test04.service;
2. public interface IPersonService {
3. public void processSave();
4. }

PersonService.java

1. package com.deppon.test04.service.impl;
2. import com.deppon.test04.dao.IPersonDao;
3. import com.deppon.test04.service.IPersonService;
4. public class PersonService implements IPersonService {
5. private IPersonDao personDao;
6. public void setPersonDao(IPersonDao personDao) {
7. this.personDao = personDao;
8. }
9. @Override
10. public void processSave() {
11. System.out.println("-------------from PersonService.processSave()");
12. personDao.save();
13. }
14. }

测试类：PersonServiceTest.java

1. package com.deppon.test04.service;
2. import org.junit.Before;
3. import org.junit.Test;
4. import org.springframework.beans.factory.BeanFactory;
5. import org.springframework.context.support.ClassPathXmlApplicationContext;
6. public class PersonServiceTest {
7. private BeanFactory factory = null;
8. @Before
9. public void before() {
10. factory = new ClassPathXmlApplicationContext("applicationContext.xml");
11. }
12. @Test
13. public void testSpring() {
14. IPersonService personService = (IPersonService) factory.getBean("personService");
15. personService.processSave();
16. }
17. }

项目结构如下图所示：
