如何搭建spring环境

起因

今天领导丢给了一个spring+flink+kafka+clickhouse的项目代码，这个代码里面已经搭好了框架，具体的业务逻辑要从另一套storm+kafka+elasticsearch里面去拿。

已经有猛男在这个项目上面奋战了，领导照顾给我们这种小卡了咪机会学习代码。

但是平时做的大数据的项目和spring不太沾边，spring这块确实不太懂。

平时都是spark，flink，hql。

这次刚好当做一个机会好好学习一下。

今天先搭建一下spring的环境。

统一jdk版本和pom文件

今天test依赖给搞了，报了错误
类文件具有错误的版本 55.0应为 52.0
所以要统一一下jdk和pom文件


POM文件：

</project>

现在环境搭好了

可以写点代码试试看

package dao;

/**
 * @Author: zsz
 * @Date: 2022/6/9 11:30
 */
public class HelloWorld {
    private String message;
    public void setMessage(String message){
        this.message = message;
    }
    public void getMessage(){
        System.out.println("message: "+message);
    }
}

package test;

import dao.HelloWorld;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.testng.annotations.Test;

/**
 * @Author: zsz
 * @Date: 2022/6/9 11:33
 */
public class Main {
    @Test
    public void testing() {
        ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
        HelloWorld helloWorld = (HelloWorld) context.getBean("HelloWorld");
        helloWorld.getMessage();
    }
}

配置代码块

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id = "HelloWorld" class="dao.HelloWorld">
        <property name="message" value="How you doing"/>
    </bean>

</beans>

执行结果图

spring的环境搭建就到这里告一段落了
可以照着我这个试试
嘿嘿 下午接着学习了
