正则采集器之二——后台搭建-优快云博客

本文链接：https://blog.youkuaiyun.com/guzhangyu12345/article/details/140735451

本人是java程序员，所以使用java界流行的架构来搭建后台。后台使用java作为后端语言，mysql作为数据库，redis作为缓存中间件。采用SpringBoot作为java端依赖管理、bean生命周期管理的容器，mybatis作为数据库持久化框架，shiro作为鉴权框架。

1、新建maven项目

命名为reptile，接着加入依赖:

	            </executions>
	        </plugin>

	</build>
</project>

接着新建包

com.learn.reptile.config 配置文件
com.learn.reptile.entity 实体类
com.learn.reptile.mapper 数据库操作接口
com.learn.reptile.utils 工具类
com.learn.reptile.web web层类

新建启动类 ReptileApplication

package com.learn.reptile;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(scanBasePackages = "com.learn.reptile")
public class ReptileApplication {
	
	public static void main(String[] args) {
		SpringApplication.run(ReptileApplication.class, args);
	}

}

2、配置文件

在src/main/resources下新建配置文件application.yml，内容如下:

server:
  port: 8080
  
spring:
  application:
    name: reptile
  main:
    allow-bean-definition-overriding: true
  jackson:
    date-format: yyyy-MM-dd HH:mm
    time-zone: GMT+8
  servlet:
    multipart:
      max-file-size: 100MB
      max-request-size: 100MB
  redis:
    database: 1
    host: sincerely-host
    password: 85861367LiGzy
  datasource:
    username: test
    password: test
    url: jdbc:mysql://localhost:3306/reptile?useUnicode=true&useSSL=false&characterEncoding=utf-8&serverTimezone=Asia/Shanghai&allowMultiQueries=true&allowPublicKeyRetrieval=true
    driver-class-name: com.mysql.cj.jdbc.Driver
    initial-size: 2
    min-idle: 1
    max-active: 20
    max-wait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: "select 'x'"
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    maxPoolPreparedStatementPerConnectionSize: 20
    filters: stat
    
mybatis-plus:
  global-config:
    id-type: 0
    db-column-underline: false
    refresh-mapper: true
  type-aliases-package: com.learn.reptile.entity.po
  mapper-locations: classpath:/mapper/*.xml
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    
    
logging:
  config: classpath:log4j2.xml

shiro:
  session-timeout: 1000000

log4j2.xml定义好日志级别、记录位置和格式

<?xml version="1.0" encoding="UTF-8"?>

        <Property name="LOG_PATTERN">
