Spring环境配置

1. 通过@SpringBootApplication加载配置文件，构建spring上下文环境

   ​ 核心 ： 构建 ApplicationContext , 然后通过 ApplicationContext 获取bean

   @SpringBootApplication(scanbasePackages ={
           "com.pachira.xkz.hh"
   })
   public class Mainhh {
       public static void main(String[] args) throws InterruptedException {
   
   
           ApplicationContext context = SpringApplication.run(Mainhh.class, args);
           SpringManager manager = context.getBean(SpringManager.class);
           for(int i=0;i<1000;i++) {
               ArchiveNode node = new ArchiveNode();
               node.setName(" " + i );
               System.out.println(node.toString());
               manager.doIt(node);
           }
           System.out.println("执行成功");
       }
   }
   

2. 通过 AnnotationConfigApplicationContext，和spring环境文件springConfig 配置 ApplicationContext

SpringConfig.java 配置spring环境

package com.pachira.xkz.hh;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import org.springframework.core.io.FileSystemResource;

@Configuration
@ComponentScan(basePackages = {
        "com.pachira.xkz.hh"
})
public class SpringConfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer createPlaceHolderCOnfigure() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean
    public SpringManager getManager() {
        return new SpringManager();
    }

    @Bean
    public ArchiveDisPactcher getDispatcher() {
        return new ArchiveDisPactcher();
    }

//有配置文件的情况   SpringConfig要有Path属性用来设置配置文件
//
//    @Bean
//    public static PropertySourcesPlaceholderConfigurer createPlaceholderConfigurer() {
//        PropertySourcesPlaceholderConfigurer configurer =
//                new PropertySourcesPlaceholderConfigurer();
//        configurer.setLocation(new FileSystemResource(configPath));
//        configurer.setFileEncoding("UTF-8");
//        return configurer;
//    }

}

    public static void main(String[] args) {
        ApplicationContext context  = new AnnotationConfigApplicationContext(SpringConfig.class);

        SpringManager manager = context.getBean(SpringManager.class);

        for(int i=0;i<1000;i++) {
            ArchiveNode node = new ArchiveNode();
            node.setName("** " + i);
            manager.doIt(node);
        }

        System.out.println("执行成功");

    }
