2021-12-09 spring boot 集成 华为云obs

Posted 2023-05-05

参考技术A           首先作为一个00后的程序员小白，集成第三方的东西真的是挺费劲的，百度之后写完发现全是坑。无奈自己用比较笨的方法写出来一套。奉献给各位新入职的程序员小白，如果项目要求不高可以使用。

第一步：引入依赖 集成sdk

第二步 ： 配置yaml文件

第三步 ： 写配置类

/**

* OBS桶名

*/

@Value("$obs.bucketname")

private String bucketname;

/**

* 上传至OBS桶的存储对象名

*/

//@Value("$obs.config.objectname")

private String objectname;

/**

* 连接OBS的endPoint

*/

@Value("$obs.endPoint")

private String endPoint;

/**

* AK

*/

@Value("$obs.ak")

private String ak;

/**

* SK

*/

@Value("$obs.sk")

private String sk;

/** 图片位置 */

private String picLocation;

/** http或https 域名 */

@Value("$obs.domain-name")

private String domainName;

public static String BUCKET_NAME;

public static String END_POINT;

public static String AK;

public static String SK;

public static String DOMAINNAME;

@Override

public void afterPropertiesSet()throws Exception

BUCKET_NAME =this.bucketname;

END_POINT =this.endPoint;

AK =this.ak;

SK =this.sk;

DOMAINNAME =this.domainName;



最后写一个工具了类随意调用

public class ObsUtil

/**

    * 文件上传

    * @param file 待上传的文件

    * @param directory 指定存储的文件夹

    * @return

*/

    public static String uploadIdentity(MultipartFile file,String directory)

if (file ==null) return"文件不可以为空！";

String url ="";

String endPoint =ObsConfig.END_POINT;

String ak =ObsConfig.AK;

String sk =ObsConfig.SK;

String bucketname =ObsConfig.BUCKET_NAME;

String domainName =ObsConfig.DOMAINNAME;

// 创建ObsClient实例

        ObsClient obsClient =new ObsClient(ak,sk,endPoint);

String str = file.getOriginalFilename();

String name =str.substring(str.lastIndexOf(".")+1);

SnowflakeIdWorker idWorker =new SnowflakeIdWorker(0,0);

long id =idWorker.nextId();

String name1 =id +"."+name;

String objectName =directory +name1;

try

// 待上传的本地文件路径，需要指定到具体的文件名

            obsClient.putObject(bucketname,objectName, file.getInputStream());

url ="https://"+domainName +"/" +objectName;

catch (IOException e)

e.printStackTrace();



return url;



/**

*

    * @param path

    * @param directory

    * @return

*/

      public static String upload(String path,String directory)

if (path ==null) return"文件不可以为空！";

String url ="";

String endPoint =ObsConfig.END_POINT;

String ak =ObsConfig.AK;

String sk =ObsConfig.SK;

String bucketname =ObsConfig.BUCKET_NAME;

// 创建ObsClient实例

          ObsClient obsClient =new ObsClient(ak,sk,endPoint);

path = path.trim();

String objectName = directory+

path.substring(path.lastIndexOf("/")+1);

FileInputStream fis =null;

String url1 ="";

try

fis =new FileInputStream(new File(path));

obsClient.putObject(ObsConfig.BUCKET_NAME,objectName, fis);

url1 =endPoint +"/" +objectName;

catch (FileNotFoundException e)

e.printStackTrace();



return url1;

spring boot 集成 mybatis

spring boot 集成 mybatis 需要加入pom依赖

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.0.0</version>
</dependency>

<dependency>
   groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>5.1.39</version>
</dependency>

数据库连接驱动和mybatis的starter

因为springboot建议不使用xml配置文件的导入方式来配置，所以将集成mybatis的配置全部设置在了application.properties

如图：

###spring datasource###
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/sms?useUnicode=true&characterEncoding=gbk&zeroDateTimeBehavior=convertToNull
spring.datasource.username=zhenghuasheng
spring.datasource.password=zhs2111014
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.max-active=10
spring.datasource.max-wait=10000
spring.datasource.max-idle=5
spring.datasource.min-idle=0
###mybatis config###
mybatis.mapper-locations=classpath:/mybatis/*Mapper.xml
mybatis.type-aliases-package=com.sample.model
###spring mvc 静态文件指定####
spring.mvc.static-path-pattern=/**
spring.resources.cache-period=864000
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.html

相应的mapper的xml文件和mapper接口正常定义

spring boot入口类添加注解扫描mapper接口，如下所示：

@SpringBootApplication
@MapperScan("com.sample.dao")
public class SampleMybatisApplication

        private static Logger logger = Logger.getLogger(SampleMybatisApplication.class);

    /**
         * Main Start
         */
        public static void main(String[] args) 
            SpringApplication.run(SampleMybatisApplication.class, args);
            logger.info("============= SpringBoot Start Success =============");
        

    

集成完成
