5 SpringBoot整合
5.1 操作步骤
- 配置FastDFS执行环境
- 文件上传配置
- 整合Swagger2测试接口

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
import com.github.tobato.fastdfs.domain.fdfs.StorePath;
import com.github.tobato.fastdfs.service.FastFileStorageClient;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.util.StringUtils;
import org.springframework.web.multipart.MultipartFile;
import javax.annotation.Resource;
@Component
public class FileDfsUtil {
private static final Logger LOGGER = LoggerFactory.getLogger(FileDfsUtil.class);
@Resource
private FastFileStorageClient storageClient ;
/**
* 上传文件
*/
public String upload(MultipartFile multipartFile) throws Exception{
String originalFilename = multipartFile.getOriginalFilename().
substring(multipartFile.getOriginalFilename().
lastIndexOf(".") + 1);
StorePath storePath = this.storageClient.uploadImageAndCrtThumbImage(
multipartFile.getInputStream(),
multipartFile.getSize(),originalFilename , null);
return storePath.getFullPath() ;
}
/**
* 删除文件
*/
public void deleteFile(String fileUrl) {
if (StringUtils.isEmpty(fileUrl)) {
LOGGER.info("fileUrl == >>文件路径为空...");
return;
}
try {
StorePath storePath = StorePath.parseFromUrl(fileUrl);
storageClient.deleteFile(storePath.getGroup(), storePath.getPath());
} catch (Exception e) {
LOGGER.info(e.getMessage());
}
}
}
5.3.4 文件上传配置
spring:
application:
name: fdfs-demo
jackson:
time-zone: GMT+8
date-format: yyyy-MM-dd HH:mm:ss
servlet:
multipart:
max-file-size: 100MB
max-request-size: 100MB
enabled: true
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();
}
}
启动类：
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@EnableSwagger2
@SpringBootApplication
public class FdfsDemoApplication {
public static void main(String[] args) {
SpringApplication.run(FdfsDemoApplication.class, args);
}
}
5.3.6 API接口
import com.itheima.fdfs.demo.common.FileDfsUtil;
import io.swagger.annotations.ApiOperation;
import org.springframework.http.ResponseEntity;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import javax.annotation.Resource;
@RestController
public class FileController {
@Resource
private FileDfsUtil fileDfsUtil ;
/**
* http://localhost:8081/swagger-ui.html
*/
@ApiOperation(value="上传文件", notes="测试FastDFS文件上传")
@RequestMapping(value = "/uploadFile",headers="content-type=multipart/form-data", method = RequestMethod.POST)
public ResponseEntity<String> uploadFile (@RequestParam("file") MultipartFile file){
String result ;
try{
String path = fileDfsUtil.upload(file) ;
if (!StringUtils.isEmpty(path)){
result = path ;
} else {
result = "上传失败" ;
}
} catch (Exception e){
e.printStackTrace() ;
result = "服务异常" ;
}
return ResponseEntity.ok(result);
}
/**
* 文件删除
*/
@RequestMapping(value = "/deleteByPath", method = RequestMethod.GET)
public ResponseEntity<String> deleteByPath (){
String filePathName = "group1/M00/00/00/rBIAAmNmi82AJxLsAABdrZgsqUU214.jpg" ;
fileDfsUtil.deleteFile(filePathName);
return ResponseEntity.ok("SUCCESS") ;
}
}
