✍How To Develop

• 비밀번호 암호화 사용

  package com.wooribank.backend.configuration;
  
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Configuration;
  import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
  import org.springframework.security.crypto.password.PasswordEncoder;
  
  @Configuration
  public class SecurityConfiguration {
  
      @Bean
      public PasswordEncoder passwordEncoder() {
          return new BCryptPasswordEncoder();
      }
  }
  

• 계좌인증 API 사용(@PostMapping("/account/update/all") accountService.updateAllAccounts)

  package com.wooribank.backend.configuration;
  
  import org.springframework.boot.autoconfigure.http.HttpMessageConverters;
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Configuration;
  import org.springframework.http.converter.HttpMessageConverter;
  import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
  import org.springframework.web.client.RestTemplate;
  
  @Configuration
  public class RestTemplateConfiguration {
  
      @Bean
      public RestTemplate restTemplate() {
          RestTemplate restTemplate = new RestTemplate();
          MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
          restTemplate.getMessageConverters().add(converter);
          return restTemplate;
      }
  
  
  }
  

• API 문서 자동화 규격 제공 (http://localhost:8080/swagger-ui/index.html)

  package com.wooribank.backend.configuration;
  
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Configuration;
  import springfox.documentation.builders.PathSelectors;
  import springfox.documentation.builders.RequestHandlerSelectors;
  import springfox.documentation.spi.DocumentationType;
  import springfox.documentation.spring.web.plugins.Docket;
  import springfox.documentation.swagger2.annotations.EnableSwagger2;
  
  @Configuration
  public class SwaggerConfiguration {
      @Bean
      public Docket api() {
          return new Docket(DocumentationType.SWAGGER_2)
                  .select()
                  .apis(RequestHandlerSelectors.basePackage("com.wooribank.backend.controller"))
                  .paths(PathSelectors.any())
                  .build();
      }
  }
