SpringBoot2 整合 Swagger2

SpringBoot 整合三板斧

第一步、引入 pom

<dependency>
  <groupId>com.spring4all</groupId>
  <artifactId>swagger-spring-boot-starter</artifactId>
  <version>1.9.0.RELEASE</version>
</dependency>
<dependency>
  <groupId>com.github.xiaoymin</groupId>
  <artifactId>swagger-bootstrap-ui</artifactId>
  <version>1.9.6</version>
</dependency>

<dependency>
  <groupId>io.swagger</groupId>
  <artifactId>swagger-annotations</artifactId>
  <version>1.5.22</version>
</dependency>
<dependency>
  <groupId>io.swagger</groupId>
  <artifactId>swagger-models</artifactId>
  <version>1.5.22</version>
</dependency>

swagger-spring-boot-starter该我的项目次要利用 Spring Boot 的自动化配置个性来实现疾速的将 swagger2 引入 spring boot 利用来生成 API 文档,简化原生应用 swagger2 的整合代码。

swagger-bootstrap-uispringfox-swagger 的加强 UI 实现,为 Java 开发者在应用 Swagger 的时候,能领有一份简洁、弱小的接口文档体验

swagger-annotations,swagger-models是因为 springfox-swagger2 包里有 swagger-models-1.5.20.jar 报错。所以替换成 1.5.22 版本

java.lang.NumberFormatException: For input string: ""
    at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
    at java.lang.Long.parseLong(Long.java:601)
    at java.lang.Long.valueOf(Long.java:803)
    at io.swagger.models.parameters.AbstractSerializableParameter.getExample(AbstractSerializableParameter.java:412)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
    at......

看下 1.5.20 版本里 AbstractSerializableParameter.java 源码:

public Object getExample() {if (this.example == null) {return null;} else {
        try {if ("integer".equals(this.type)) {return Long.valueOf(this.example);
            }
        
            if ("number".equals(this.type)) {return Double.valueOf(this.example);
            }

            if ("boolean".equals(this.type) && ("true".equalsIgnoreCase(this.example) || "false".equalsIgnoreCase(this.defaultValue))) {return Boolean.valueOf(this.example);
            }
        } catch (NumberFormatException var2) {LOGGER.warn(String.format("Illegal DefaultValue %s for parameter type %s", this.defaultValue, this.type), var2);
        }

        return this.example;
    }
}

这里只判断了 this.example == null 才返回 null,其余会去进行转换,而空字符串也会进行转换,导致格局抛出格式化转换异样. 再来看下 1.5.22 版本里 AbstractSerializableParameter.java 源码:

public Object getExample() {if (this.example != null && !this.example.isEmpty()) {
        try {if ("integer".equals(this.type)) {return Long.valueOf(this.example);
            }

            if ("number".equals(this.type)) {return Double.valueOf(this.example);
            }

            if ("boolean".equals(this.type) && ("true".equalsIgnoreCase(this.example) || "false".equalsIgnoreCase(this.defaultValue))) {return Boolean.valueOf(this.example);
            }
        } catch (NumberFormatException var2) {LOGGER.warn(String.format("Illegal DefaultValue %s for parameter type %s", this.defaultValue, this.type), var2);
        }

        return this.example;
    } else {return this.example;} 
}

对 example 同时进行了 null 和空值的判断,官网也发现了本人的这个问题,咱们进行相应的替换即可

第二部、配置

swagger-spring-boot-starter相干配置信息可参考如下地址:

  • 源码地址

    • GitHub:https://github.com/dyc87112/s…

  • 应用样例:https://github.com/dyc87112/s…

  • 社区:http://www.spring4all.com

swagger-bootstrap-ui相干配置信息可参考如下地址:

官网地址:https://doc.xiaominfo.com/guide/

swagger-bootstrap-ui目前已改名了knife4j-spring-boot-starter

我的项目正式更名为knife4j, 取名 knife4j 是心愿她能像一把匕首一样玲珑, 轻量, 并且性能强悍, 更名也是心愿把她做成一个为 Swagger 接口文档服务的通用性解决方案, 不仅仅只是专一于前端 Ui 前端.

swagger-bootstrap-ui 的所有个性都会集中在 knife4j-spring-ui 包中, 并且后续也会满足开发者更多的个性化需要.

swagger:
  version: 1.0v # 版本号
  authorization: # 全局参数
    name: Authorization # 鉴权策略 ID,对应 SecurityReferences ID
    type: ApiKey # 鉴权策略,可选 ApiKey | BasicAuth | None,默认 ApiKey
    key-name: X-Token # 鉴权传递的 Header 参数
  #    auth-regex: ^.*$ # 须要开启鉴权 URL 的正则, 默认 ^.*$ 匹配所有 URL
  ui-config: # 排序规定
    operations-sorter: method # 按办法定义程序排序
    tags-sorter: alpha # 按字母表排序
  docket: # 分组配置
    common:
      base-package: com.xxxx.a

      title: xxx 接口

        url: https://zc.happyloves.cn

第三步、注解

@EnableSwagger2Doc // 启用 Swagger2
@EnableSwaggerBootstrapUI // 启用 swagger-bootstrap-ui
@SpringBootApplication
public class WebApplication {public static void main(String[] args) {SpringApplication.run(WebApplication.class, args);
    }
}

编写代码

@Api(value = "DemoOne-DemoOne 服务~~~~~~~~", tags = {"1-DemoOne-DemoOne 服务"})
@Slf4j
@Validated
@RestController
@RequestMapping("/common/DemoOne")
public class DemoOneController {
    private final DemoOneService service;

    @Autowired
    public DemoOneController(DemoOneService service) {this.service = service;}

    //=====================================================================================DELETE=====================================================================================
    @ApiOperation(value = "依据主键 ID 删除", notes = "依据主键 ID 删除~~~~~~~~~~~~~")
    @DeleteMapping("/{id}")
    public ApiMessage deleteById(@PathVariable @Min(1) int id) throws Exception {return service.deleteById(id);
    }

    //=====================================================================================GET========================================================================================

    @ApiOperation(value = "获取所有数据", notes = "获取所有数据~~~~~~~~~~~~~")
    @GetMapping("/")
    public ApiMessage<List<DemoOneResponse>> getAllList() {return service.getAllList();
    }

    @ApiOperation(value = "依据主键 ID 获取数据", notes = "依据主键 ID 获取数据~~~~~~~~~~~~~")
    @ApiImplicitParams(value = {@ApiImplicitParam(name = "id", required = true, value = "主键 ID", paramType = "path", dataType = "string"),
    })
    @GetMapping("/{id}/{name}")
    public ApiMessage<DemoOneResponse> getById(@PathVariable @Min(1) int id, @PathVariable @AssertFalse boolean name) {return service.getById(id);
    }

    //=====================================================================================POST=======================================================================================
    @ApiOperation(value = "新增 DemoOne 数据", notes = "新增 DemoOne 数据~~~~~~~~~~~~~")
    @PostMapping("/")
    public ApiMessage<DemoOneResponse> save(@RequestBody @Valid DemoOneRequest parameter) {return service.addDemoOne(parameter);
    }

    //=====================================================================================PUT========================================================================================
    @ApiOperation(value = "更新 DemoOne 数据", notes = "更新 DemoOne 数据~~~~~~~~~~~~~")
    @PutMapping("/")
    public ApiMessage<DemoOneResponse> update(@RequestBody @Valid DemoOneRequest parameter) {return service.update(parameter);
    }
