SpringBoot 读取配置文件

SpringBoot 读取配置文件

1.IO 流读取机密文件(打 jar 可读取）

InputStream inputStream = AuthorizationHelper.class.getClassLoader()
    .getResourceAsStream("META-INF/default-public.pem");

StringBuilder builder = new StringBuilder();
Assert.notNull(inputStream,()->"inputStream is null");
BufferedInputStream bis = new BufferedInputStream(inputStream,1024);
byte[] buffer = new byte[1024];
int length = 0;
while ((length = bis.read(buffer))!=-1){
  builder.append(new String(buffer,0,length, StandardCharsets.UTF_8));
}
String publicKeyStr = builder.toString();

2.@EnableConfigurationProperties 读取配置文件

@Configuration
@EnableConfigurationProperties({RemoteServerProperties.class})
public class RemoteConfiguration {
  //properties配置文件前缀
  @ConfigurationProperties(prefix = "remote.url") 
  @Data
  public static class RemoteServerProperties{
    //aorpApiServer 对应properties文件的aorp-api-server
    private String aorpApiServer;
  }
}

//properties配置文件
remote.url.aorp-api-server: http://192.168.1.159:7777/aorp

3.@Value 读取配置文件(维护成本高)
