5.3 客户端开发

5.3.1 FastDFS配置

fdfs:
  # 链接超时
  connect-timeout: 60
  # 读取时间
  so-timeout: 60
  # 生成缩略图参数
  thumb-image:
    width: 150
    height: 150
  tracker-list: 192.168.86.101:22122

5.3.2 FastDFS配置类

@Configuration
@Import(FdfsClientConfig.class)
// 避免Jmx重复注册bean
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
public class DFSConfig {

5.3.3 文件工具类

5.3.5 配置Swagger2

配置类：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

/**
 * Swagger 配置文件
 */
@Configuration
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.itheima.fdfs.demo"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("SpringBoot利用Swagger构建API文档")
                .description("Fast DFS接口")
                .version("version 1.0")
                .build();
