Spring boot 整合 Swagger

环境准备

  1. JDK版本:1.8
  2. Spring boot版本:1.5.16
  3. Swagger及其Swagger-ui版本:2.6.1(关于swagger-ui版本 每个版本的汉化方式可能有不同)
  4. 默认url:http://localhost:8080/swagger-ui.html

Maven依赖

<!-- swagge2 -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.6.1</version>
</dependency>
<!-- swaggerui用于展示swagger页面 -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.6.1</version>
</dependency>

注意事项:

swagger-ui依赖 有可能会与com.google.guava冲突 提供一个解决办法:

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.2.2</version>
    <!-- 将冲突包移除 -->
    <exclusions>
        <exclusion>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
        </exclusion>
    </exclusions>
</dependency>

配置文件

@Configuration
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket api() {
        // 统一设置返回描述
        List<ResponseMessage> responseMessages = new ArrayList<>();
        responseMessages.add(new ResponseMessageBuilder().code(400).message("请求参数有误").build());
        responseMessages.add(new ResponseMessageBuilder().code(401).message("未授权").build());
        responseMessages.add(new ResponseMessageBuilder().code(403).message("禁止访问").build());
        responseMessages.add(new ResponseMessageBuilder().code(404).message("请求路径不存在").build());
        responseMessages.add(new ResponseMessageBuilder().code(500).message("服务器内部错误").responseModel(new ModelRef("string")).build());

        return new Docket(DocumentationType.SWAGGER_2)
                // 禁用默认返回描述
                .useDefaultResponseMessages(false)
                // 启用新的返回描述
                .globalResponseMessage(RequestMethod.GET, responseMessages)
                .globalResponseMessage(RequestMethod.POST, responseMessages)
                .globalResponseMessage(RequestMethod.PATCH, responseMessages)
                .globalResponseMessage(RequestMethod.PUT, responseMessages)
                .globalResponseMessage(RequestMethod.DELETE, responseMessages)
                // 设置基本信息
                .apiInfo(apiInfo())
                .select()
                // 设置哪些api被扫描
                .apis(RequestHandlerSelectors.basePackage("cn.willvi.springbootswaggerdemo"))
                // 设置路径
                .paths(PathSelectors.any())
                .build();
    }

    /**
     * 设置基本信息
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                // 标题
                .title("我的接口文档")
            	// 描述
                .description("这是我的第一个接口文档")
            	// 版本号

                // 作者
                .license("willvi")
                .licenseUrl("")
                .build();
    }
}

Swagger注解详解

@Api 设置Controller整体信息

注解位置:Controller类上

/**
 * value                 url路径值(汉化后不起作用) http://xxx/swagger-ui.html#/demo-controller中的 demo-controller即为value
 * tags                  设置这个值、value的值会被覆盖(汉化后有bug最好不写)
 * description           对api资源的描述
 * basePath              基本路径可以不配置
 * position              如果配置多个Api 想改变显示的顺序位置
 * produces              例如, "application/json, application/xml"  页面上的 Response Content Type (响应Content Type)
 * consumes              例如, "application/json, application/xml"
 * protocols             Possible values: http, https, ws, wss.
 * authorizations        高级特性认证时配置
 * hidden                配置为true 将在文档中隐藏
 */
@Api(value = "Swagger 注解使用",description = "123")

@ApiOperation 设置每个方法(接口)信息

注解位置:方法上

  /**
     * value               页面tab右侧值
     * tags                如果设置这个值、value的值会被覆盖
     * description         对api资源的描述
     * basePath            基本路径可以不配置
     * position            如果配置多个Api 想改变显示的顺序位置
     * produces            例如, "application/json, application/xml"
     * consumes            例如, "application/json, application/xml"
     * protocols           Possible values: http, https, ws, wss.
     * authorizations      高级特性认证时配置
     * hidden              配置为true 将在文档中隐藏
     * response            返回的对象
     * responseContainer   这些对象是有效的 "List", "Set" or "Map".,其他无效
     * httpMethod  "GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS" and "PATCH"
     * code                http的状态码 默认 200
     * extensions          扩展属性
     */
     @ApiOperation(
            value = "post",
            notes = "这是一个小demo",
            produces = "application/json",
            response = Person.class
    )

@ApiImplicitParams 与 @ApiImplicitParam 设置传入参数信息

注解位置:方法上

注意事项: name必须与参数名相同,不然多出一个参数框

    /**
     * @ApiImplicitParam
     * 当dataType不是对象时可以使用
     *
     * paramType:参数放在哪个地方
     * name:参数代表的含义
     * value:参数名称
     * dataType: 参数类型,有String/int,无用
     * required : 是否必要
     * defaultValue:参数的默认值
     */
    @ApiImplicitParams(
            @ApiImplicitParam(name = "name",value = "name",paramType ="path", dataType = "String")
    )

@ApiResponses 设置返回的一些状态码信息

注解位置:方法上

 /**
     * code                http的状态码
     * message             描述
     * response            默认响应类 Void
     * reference           参考ApiOperation中配置
     * responseHeaders     参考 ResponseHeader 属性配置说明
     * responseContainer   参考ApiOperation中配置
     */
@ApiResponses({@ApiResponse(code = 500, message = "服务器内部错误", response = String.class)})

@ApiModel

描述一个Model的信息(这种一般用在post创建的时候,使用@RequestBody这样的场景,请求参数无法使用@ApiImplicitParam注解进行描述的时候

注解位置:实体类上

@ApiModelProperty

描述一个model的属性。

注解位置:实体类每个属性上面

@ApiModelProperty(value = "姓名",name = "name")

@ApiParam

注解位置:方法参数内

 /**
     * name	属性名称
     * value	属性值
     * defaultValue	默认属性值
     * allowableValues	可以不配置
     * required	是否属性必填
     * access	不过多描述
     * allowMultiple	默认为false
     * hidden	隐藏该属性
     * example	举例子
     */
 public ResponseEntity<String> placeOrder(
      @ApiParam(value = "xxxx", required = true) Person person) {
    storeData.add(order);
    return ok("");
  }

Controler示例

@Api(value = "Swagger 注解使用")

@RestController
@RequestMapping("/")


public class DemoController {
    @PostMapping("/postHello")
    /**
     * value               url的路径值
     * tags                如果设置这个值、value的值会被覆盖
     * description         对api资源的描述
     * basePath            基本路径可以不配置
     * position            如果配置多个Api 想改变显示的顺序位置
     * produces            例如, "application/json, application/xml"
     * consumes            例如, "application/json, application/xml"
     * protocols           Possible values: http, https, ws, wss.

    )
    public String hello(@PathVariable String name){
        return "hello " + name;

Model示例

// 描述一个Model的信息
@ApiModel
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class Person {
    @ApiModelProperty(value = "姓名",name = "name")
    String name;
    int age;
}

swagger汉化

  1. 在resources资源下创建 META-INF/resources 文件夹并创建名为swagger-ui.html文件

  2. 复制以下内容:
