Swagger

在项目中使用swagger需要springfox；

• swagger2
• ui

SpringBoot继承Swagger

1. 新建一个springboot==web项目

2. 导入swagger依赖（在仓库搜索springfox swag）

   <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
   <dependency>
       <groupId>io.springfox</groupId>
       <artifactId>springfox-swagger2</artifactId>
       <version>2.9.2</version>
   </dependency>
   <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
   <dependency>
       <groupId>io.springfox</groupId>
       <artifactId>springfox-swagger-ui</artifactId>
       <version>2.9.2</version>
   </dependency>
   

   3. 编写一个helloworld的程序

   4. 配置Swagger==》Config

      @Configuration
      @EnableSwagger2  //开启Swagger2
      public class SwaggerConfig {
      }
      

3. 测试运行

   localhost:8080/swagger-ui.html

配置Swagger

Swagger的bean实例Docket

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket docket(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo());
    }
    //配置Swagger信息apiInfo
    private ApiInfo apiInfo(){
        //作者信息
         Contact contact = new Contact("黑黑", "www.baidu.com", "577055183@qq.com");
        return new ApiInfo(
                "黑黑的Swagger日记",
                "即使再小的帆也能远航",
                "1.0",
                "www.baidu.com",
                contact,
                "Apache 2.0",
                "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList());

    }
}

Swagger配置扫描接口

@Bean
public Docket docket(){
    return new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(apiInfo())
            .select()
            //RequestHandlerSelectors配置要扫描接口的方式
            //basePackage配置要扫描的包
            .apis(RequestHandlerSelectors.basePackage("com.lr.controller"))
            //过滤什么路径
            .paths(PathSelectors.ant("/kuang/**"))
            .build();
}

配置是否启动Swagger

@Bean
public Docket docket(){
    return new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(apiInfo())
            //禁用swagger
            .enable(false)
            .select()
            //RequestHandlerSelectors配置要扫描接口的方式
            //basePackage配置要扫描的包
            .apis(RequestHandlerSelectors.basePackage("com.lr.controller"))
            //过滤什么路径
          //  .paths(PathSelectors.ant("/kuang/**"))
            .build();
}

我只希望我的Swagger在生产环境中使用，在发布的时候不适用？

• 判断是不是生产环境 flag = false
• 注入enable(flag)

@Bean
public Docket docket(Environment environment){
    //设置要显示的swagger环境
    Profiles profiles = Profiles.of("dev","test");
    //获得项目的环境
    boolean flag = environment.acceptsProfiles(profiles);
    return new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(apiInfo())
            //禁用swagger
            .enable(flag)
            .select()
            //RequestHandlerSelectors配置要扫描接口的方式
            //basePackage配置要扫描的包
            .apis(RequestHandlerSelectors.basePackage("com.lr.controller"))
            //过滤什么路径
          //  .paths(PathSelectors.ant("/kuang/**"))
            .build();
}

配置API文档的分组

.groupName("黑黑")

如何配置多个分组？多个Docket实即可

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket docket(Environment environment){
        //设置要显示的swagger环境
        Profiles profiles = Profiles.of("dev","test");
        //获得项目的环境
        boolean flag = environment.acceptsProfiles(profiles);
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .groupName("黑黑")
                //禁用swagger
                .enable(flag)
                .select()
                //RequestHandlerSelectors配置要扫描接口的方式
                //basePackage配置要扫描的包
                .apis(RequestHandlerSelectors.basePackage("com.lr.controller"))
                //过滤什么路径
              //  .paths(PathSelectors.ant("/kuang/**"))
                .build();
    }
    @Bean
    public Docket docket1(Environment environment){
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("A");
    }
    @Bean
    public Docket docket2(Environment environment){
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("B");
    }
    @Bean
    public Docket docket3(Environment environment){
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("C");
    }
    //配置Swagger信息apiInfo
    private ApiInfo apiInfo(){
        //作者信息
         Contact contact = new Contact("黑黑", "www.baidu.com", "xxxxxxx@qq.com");
        return new ApiInfo(
                "黑黑的Swagger日记",
                "即使再小的帆也能远航",
                "1.0",
                "www.baidu.com",
                contact,
                "Apache 2.0",
                "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList());

    }
}

实体类配置

@ApiModel("用户实体类")
public class User {
    @ApiModelProperty("用户名")
    public String username;
    @ApiModelProperty("密码")
    public String password;

}

@RestController
public class HelloController {
    @GetMapping(value = "/hello")
    public String hello(){
        return "hello";
    }
    //
    @PostMapping(value = "/user")
    public User user(){
        return new User();
    }
    @ApiOperation("Hello控制类")
    @PostMapping ("/hello2")
    public String hello2(@ApiParam("用户名") String username){
            return "hello"+username;
    }
    @PostMapping ("/hello3")
    public User hello2(@ApiParam("用户名") User user){
        return user;
    }
}

总结：

​ 【注意点】：正式发布的时候关闭swagger！！！处于安全考虑。而且节省运行内存。
