作用

用注解的方式动态切换实现类实现方式。
比如我们有多个消息中间件或多个短信服务商，需要动态切换的时候，无需自己写判断逻辑来进行服务商的切换。只用一套注解就可以解决问题

开始使用

引入依赖

<dependency><groupId>io.github.burukeyou</groupId><artifactId>spring-smart-di-all</artifactId><version>0.2.0</version>
</dependency>

下载不下来需要拿到jar包打入本地仓库

mvn install:install-file -Dfile=D://spring-smart-di-all-0.2.0.jar -DgroupId=io.github.burukeyou -DartifactId=spring-smart-di-all -Dversion=0.2.0 -Dpackaging=jar

jar包在我的下载里面有上传

开启注解使用

package com.dino;import com.burukeyou.smartdi.annotations.EnableSmartDI;
import lombok.extern.slf4j.Slf4j;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;@Slf4j
@EnableSmartDI
@SpringBootApplication
public class DinoOaApp {public static void main(String[] args) {log.info("====== Business Starting... ======");ConfigurableApplicationContext ctx = null;try {ctx = new SpringApplicationBuilder(DinoOaApp.class).web(WebApplicationType.SERVLET).run(args);log.info("====== Business Started! ======");} catch (Exception e) {if (ctx != null) {log.error("Business application start failed and exit: {}", e.getMessage(), e);System.exit(SpringApplication.exit(ctx));}}}
}

实现类实现

定义实现类

package com.dino.business.sms;import com.burukeyou.smartdi.proxyspi.spi.EnvironmentProxySPI;
import com.dino.utils.sms.SmsSendRequest;@EnvironmentProxySPI("${sms.impl}")
public interface SmsService {Boolean sendSms(String mobile);
}

实现实现类

package com.dino.business.sms.impl;import com.burukeyou.smartdi.annotations.BeanAliasName;
import com.dino.business.sms.SmsService;
import com.dino.utils.sms.SmsSendRequest;
import com.dino.utils.sms.SmsUtils;
import org.springframework.stereotype.Component;import javax.annotation.Resource;/*** 阿里短信发送*/
@BeanAliasName("ali")
@Component
public class AliSmsServiceImpl implements SmsService {@Resourceprivate SmsUtils smsUtils;@Overridepublic Boolean sendSms(String mobile) {return smsUtils.sendAliSMS(mobile);}
}

package com.dino.business.sms.impl;import com.burukeyou.smartdi.annotations.BeanAliasName;
import com.dino.business.sms.SmsService;
import com.dino.utils.sms.SmsSendRequest;
import com.dino.utils.sms.SmsUtils;
import org.springframework.stereotype.Component;import javax.annotation.Resource;/*** 创蓝短信发送*/
@BeanAliasName("cl")
@Component
public class ClSmsServiceImpl implements SmsService {@Resourceprivate SmsUtils smsUtils;@Overridepublic Boolean sendSms(String mobile) {return smsUtils.sendClSms(mobile);}
}

配置文件配置

# 短信类型  阿里：ali  创蓝 cl
sms:impl: cl
接口调用@AutowiredProxySPIprivate SmsService smsService;public Boolean sendSmsCode(String mobile) {     return smsService.sendSms(mobile);}
