IntelliJ IDEA上使用Maven创建Spring项目

step1.配置maven

• 1.下载apache-maven文件，选择自己需要的版本apache-maven-3.5.4-bin.zip

• 2.解压1所下载文件，本人解压到：D:\apache-maven-3.5.4

• 3.配置Maven环境变量
  a. MAVEN_HOME : D:\apache-maven-3.5.4
  b.PATH : %MAVEN_HOME%\bin;
  c. MAVEN_OPTS : -Xms128m -Xmx512m -Duser.language=zh -Dfile.encoding=UTF-8

• 4.在CMD中输入mvn -v,如出现下列信息，表示配置成功。
  其中会显示Java 配置环境以及Maven配置环境

step2.修改Maven仓库路径和配置文件

E:\repo

    E:\repo

   
      user-snapshots
      lb
      123456
    
     
    
      user-releases
      lb
      123456
    
  
    
    
        nexus-aliyun
        *
        Nexus aliyun
        http://maven.aliyun.com/nexus/content/groups/public
       
  

     
            jdk-1.10     
                 
                true     
                1.10     
                 
                 
                1.10     
                1.10     
                1.10         

step2.创建默认的spring-anno项目

• pom.xml添加

    
        
            org.springframework
            spring-context
            5.0.6.RELEASE
        
        
            junit
            junit
            4.12
            test
        
    

• 创建spring的beans.xml

• Person类

package com.enjoy.cap1;

public class Person {
    private String name;
    private Integer age;

    public Person(){
        super();
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Person(String name, Integer age) {
        super();
        this.name = name;
        this.age = age;
    }
    public Integer getAge() {
        return age;
    }
    @Override
    public String toString() {
        return "Person [name=" + name + ", age=" + age + "]";
    }
    public void setAge(Integer age) {
        this.age = age;
    }
}

• MainTest1类

package com.enjoy.cap1;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainTest1 {
    public static void main(String args[]){
        //把beans.xml的类加载到容器
        ApplicationContext app = new ClassPathXmlApplicationContext("beans.xml");
        //从容器中获取bean
        Person person = (Person) app.getBean("person");

        System.out.println(person);
    }
}
