springboot代理配置，本地访问测试环境数据库、测试环境elasticsearch

背景

本地项目启动需要直接连接测试环境的数据库、ES以及其他资源

配置

ES和其他一些资源的访问通过springboot配置走代理访问。比如我这里

@EnableAsync
@EnableScheduling
@SpringBootApplication
public class ApplicationStartUp {public static void main(String[] args) {String proxyHost = "127.0.0.1";String proxyPort = "7890";System.setProperty("http.proxyHost", proxyHost);System.setProperty("http.proxyPort", proxyPort);// 对https也开启代理System.setProperty("https.proxyHost", proxyHost);System.setProperty("https.proxyPort", proxyPort);SpringApplication.run(ApplicationStartUp.class, args);}
}

mysql访问通过配置SSH代理 复制如下代码，改下配置，然后spring.datasource.url的地址中的host和port替换为127.0.0.1:3306即可。注意引入pom
```
 <dependency><groupId>com.jcraft</groupId><artifactId>jsch</artifactId><version>0.1.55</version></dependency>

}
