java spring maven 部署 maven搭建spring

这篇随笔搭建的工程是普通的Spring工程，用于学习Spring框架，如果要搭建SpringMVC工程

第一步：在IDEA点击new -> project

左侧选择Maven,直接点击Next。第一次使用IDEA的朋友，顶部还要选择Project SDK路径，就是Java的安装路径。

这里随便填一下之后点击Next

选择项目存放路径，或者保持默认，点击Finish，来到工程页面之后，在项目文件夹上右键并选择Add Framework Support

 

 在这个页面找一下Spring,打钩。点击OK

完成后，会下载Spring的jar包，并存放在项目的lib目录下。

下载完成之后创建一个简单的项目。

四个Java文件一个appContext.xml我贴在这里

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;
    }
}

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()+"准备做作业了");
        student.doHomeWork();

        context.close();

    }
}

因为例子中使用Spring AOP,所以还需要引入一个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>

然后你就可以运行自己的Spring项目啦，main方法在App类里面。
