常用配置(持续更新)

一、Druid配置

1.1、pom文件

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid-spring-boot-starter</artifactId>
  <version>1.1.9</version>
</dependency>

1.2、application

server:
  port: 8889
#数据源
spring:
  datasource:
    name: test #数据库名称
    type: com.alibaba.druid.pool.DruidDataSource
    #druid相关配置
    druid:
      driver-class-name: com.mysql.jdbc.Driver
      #基本属性
      url: jdbc:mysql://127.0.0.1:3306/test
      username: root
      password: 123456
      #配置初始化大小/最小/最大
      initial-size: 1
      min-idle: 1
      max-active: 20
      #获取连接等待超时时间
      max-wait: 60000
      #间隔多久进行一次检测，检测需要关闭的空闲连接
      time-between-eviction-runs-millis: 60000
      #一个连接在池中最小生存的时间
      min-evictable-idle-time-millis: 300000
      validation-query: SELECT 'x'
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      #打开PSCache，并指定每个连接上PSCache的大小。oracle设为true，mysql设为false。分库分表较多推荐设置为false
      pool-prepared-statements: false
      max-pool-prepared-statement-per-connection-size: 20
      #filters: #配置多个英文逗号分隔(统计，sql注入，log4j过滤)
      filters: stat,wall
      stat-view-servlet:
        enabled: true
        url-pattern: /druid/*
  main:
    allow-bean-definition-overriding: true
 
#读取映射文件
mybatis:
  mapper-locations: classpath:mapper/*Mapper.xml

二、七牛云文件上传

2.1、准备工作

1、注册七牛云账号

2、参考官方文档创建应用

2.2、SpringBoot集成七牛云

2.2.1、pom文件

这里只贴出七牛云需要的，项目如果需要其他依赖自行加入

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>com.qiniu</groupId>
        <artifactId>qiniu-java-sdk</artifactId>
        <version>[7.2.0, 7.2.99]</version>
    </dependency>
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
        <version>1.2.7</version>
    </dependency>

2.2.2、application.yml文件

这里只贴出七牛云配置文件其他的自行加入

#--------------------------------------七牛云服务器--------------------------------------
qiniu:
  #  七牛云账号对应的 	AccessKey
  accessKey: 改成自己的ak
  #  七牛云账号对应的 	SecretKey
  secretKey: 改成自己的sk
  #  存储空间名字
  bucket: 自己的存储空间名字
  #   图片上传成功后的返回地址
  path: 自己的域名地址

注意：ak和sk到自己的七牛云个人中心的秘钥中心查看，域名是对象存储中内容管理上查看，如下图

2.2.3、工具类

                }
            }

        UploadManager uploadManager = new UploadManager(cfg);
        return uploadManager;
    }
}

2.2.4、controller

@RestController
public class QiniuController {

    @Resource
    private QiniuUtil qiniuUtil;
    @RequestMapping(value = "upload")
    public String upload(@RequestParam("file") MultipartFile file){
        FileInputStream inputStream = null;
        try {
            inputStream = (FileInputStream)file.getInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
        String path = qiniuUtil.uploadImg(inputStream, UUID.randomUUID().toString());
        System.out.println("path===>"+path);
        return path;
    }
}

到七牛云服务上就可以查看到你上传的图片了。
