@Api("附件管理")
@RestController
@RequestMapping("/attachment")
public class AttachmentController {
    @Autowired
    private AttachmentService service;

    @ApiOperation("保存附件")
    @PostMapping
    public RestResponse save(@ApiParam("附件信息") @RequestBody Attachment attachment) {
        service.save(attachment);
        return RestResponse.result(attachment);
    }

    @ApiOperation("删除附件")
    @DeleteMapping("/{id}")
    public RestResponse delete(@ApiParam(value = "附件ID", example = "1") @PathVariable String id) {
        service.delete(id);
        return RestResponse.result(id);
    }

    @ApiOperation("查询附件")
    @GetMapping
    public RestResponse query(@ApiParam(value = "附件名称", example = "1.docx") @RequestParam(required = false) String name,
                              @ApiParam(value = "页数", example = "1") @RequestParam(required = false, defaultValue = "0") int pageNum,
                              @ApiParam(value = "每页条数", example = "10") @RequestParam(required = false, defaultValue = "10") int pageSize) {
        PageInfo<Attachment> page = service.query(name, pageNum, pageSize);
        return RestResponse.result(page);
    }
}

注意事项

  1. 常用注解有@Api, @ApiOperation, @ApiParam, @ApiModelProperty
  2. @Produces, @ApiResponses受制于框架暂不使用，接口风格尽量向rest靠拢
  3. 尽量在注解中添加example属性，以方便后期在swagger-ui中做手工接口测试
  4. 注解在一定程度上可以替代/**/注释，具体看公司要求

swagge-ui

查看API信息

浏览器访问http://localhost:8090/zorrodemo/swagger-ui.html，打开swagger-ui的界面，可查看所有API的信息

API测试验证

点击Try it out按钮，可对单个接口手工进行测试

文档生成

  1. 通过swagger的原始描述json，可以使用各种工具生成多种格式的API文档(asciidoc/pdf/html/markdonwn)
  2. json api-docs的路径为: http://localhost:8090/zorrodemo/v2/api-docs
  3. 建议使用swagger-markdown工具生成markdown格式文档，方便后期格式转换、导出

安装及使用:

npm install -g swagger-markdown
swagger-markdown -i ./api-docs.json
