這篇文章主要介紹IDEA+Maven創(chuàng)建Spring項(xiàng)目的方法步驟,文中示例代碼介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們一定要看完!
第一步:在IDEA點(diǎn)擊new -> project
左側(cè)選擇Maven,直接點(diǎn)擊Next。第一次使用IDEA的朋友,頂部還要選擇Project SDK路徑,就是Java的安裝路徑。
這里隨便填一下之后點(diǎn)擊Next
選擇項(xiàng)目存放路徑,或者保持默認(rèn),點(diǎn)擊Finish,來(lái)到工程頁(yè)面之后,在項(xiàng)目文件夾上右鍵并選擇Add Framework Support
在這個(gè)頁(yè)面找一下Spring,打鉤。點(diǎn)擊OK
完成后,會(huì)下載Spring的jar包,并存放在項(xiàng)目的lib目錄下。
下載完成之后創(chuàng)建一個(gè)簡(jiǎn)單的項(xiàng)目。
四個(gè)Java文件一個(gè)appContext.xml我貼在這里
public class Student { private String name; private Homework homework; public Student(){} public Student(String name, Homework homework) { this.name = name; this.homework = homework; } public void doHomeWork(){ System.out.println(homework.getContent()); } public String getName() { return name; } public void setName(String name) { this.name = name; } public Homework getHomework() { return homework; } public void setHomework(Homework homework) { this.homework = homework; } }
public class Homework { private String content; public Homework(){} public Homework(String content) { this.content = content; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } }
public class Homework { private String content; public Homework(){} public Homework(String content) { this.content = content; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } }
import java.util.Date; public class CheckNowTime { public void beforDoHomework(){ System.out.println(new Date(System.currentTimeMillis())); } }
import org.springframework.context.support.ClassPathXmlApplicationContext; public class App { public static void main(String[] args) { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("appContext.xml"); Student student = context.getBean(Student.class); System.out.println(student.getName()+"準(zhǔn)備做作業(yè)了"); student.doHomeWork(); context.close(); } }
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!-- 讓Spring管理 Student bean --> <bean id="student" class="demo1.Student"> <property name="name" value="小明"></property> <property name="homework" ref="homework"></property> </bean> <!-- 讓Spring管理Homework bean--> <bean id="homework" class="demo1.Homework"> <property name="content" value="how to calc 3+2 ?"></property> </bean> <!-- 切面定義--> <bean id="checktime" class="demo1.CheckNowTime"></bean> <aop:config> <aop:aspect ref="checktime"> <aop:pointcut id="dohomework" expression="execution(* *.doHomeWork(..))"/> <aop:before pointcut-ref="dohomework" method="beforDoHomework"></aop:before> </aop:aspect> </aop:config> </beans>
因?yàn)槔又惺褂肧pring AOP,所以還需要引入一個(gè)jar包。我的pom.xml如下:
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>test</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.4</version> </dependency> </dependencies> </project>
然后你就可以運(yùn)行自己的Spring項(xiàng)目啦,main方法在App類里面。
