# Spring Boot 2.X - Spring Boot整合Swagger2 #

> Spring Boot能够快速开发应用程序，而Swagger2则能够快速的生成Restful APIs接口文档。本文将就两者进行简单的整合应用。  
> 文中Spring Boot版本为`2.1.4.RELEASE`，Swagger2版本为`2.9.2`

## 添加依赖 ##

利用Spring Initializr快速创建一个Spring Boot应用，并添加Swagger2依赖，主要依赖如下：

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            
            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger2</artifactId>
                <version>${swagger.version}</version>
            </dependency>
            
            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger-ui</artifactId>
                <version>${swagger.version}</version>
            </dependency>

## 创建Swagger2配置 ##

@SpringBootConfiguration
    @EnableSwagger2
    public class SwaggerConfig { 
        public Docket buildDocket(){ 
            return new Docket(DocumentationType.SWAGGER_2)
                    .apiInfo(apiInfo())
                    .select()
                    .apis(RequestHandlerSelectors.basePackage("com.xudc.swagger.controller"))
                    .paths(PathSelectors.any())
                    .build();
        }
    
        private ApiInfo apiInfo() { 
            return new ApiInfoBuilder().title("Swagger构建Restful API文档")
                    .description("文档除了查看API还可以进行调试")
                    .contact(new Contact("xudc", "https://blog.csdn.net/xudc0521", "e-mail"))
                    .version("1.0.0")
                    .build();
        }
    }

## 新建实体 ##

@Data
    @Accessors(chain = true)
    public class User { 
        private Integer id;
        private String name;
        private Integer age;
    }

## 创建接口并构建文档内容 ##

@RestController
    @RequestMapping("/user")
    public class UserController { 
    
        private static Map<Integer, User> userMap = Maps.newConcurrentMap();
        private final static String SUCCESS = "success";
    
        @ApiOperation("获取用户列表")
        @GetMapping("")
        public List<User> list(){ 
            return Lists.newArrayList(userMap.values());
        }
        @ApiOperation(value = "创建用户",notes = "根据User对象创建用户")
        @ApiImplicitParam(name = "user",value = "用户实体json",required = true,dataType = "User")
        @PostMapping("")
        public String save(@RequestBody User user) { 
            userMap.put(user.getId(), user);
            return SUCCESS;
        }
    
        @ApiOperation(value = "查询用户",notes = "根据id查找用户")
        @ApiImplicitParam(name = "id", value = "用户id", required = true, dataType = "int")
        @GetMapping("/{id}")
        public User find(@PathVariable Integer id){ 
            User user = userMap.get(id);
            return user;
        }
    
        @ApiOperation(value = "删除用户",notes = "根据id删除指定用户")
        @ApiImplicitParam(name = "id", value = "用户id", required = true, dataType = "int")
        @DeleteMapping("/{id}")
        public String delete(@PathVariable Integer id) { 
            userMap.remove(id);
            return SUCCESS;
        }
    
        @ApiOperation(value = "修改用户",notes = "根据id修改用户信息")
        @ApiImplicitParams({ 
                @ApiImplicitParam(name = "id", value = "用户id", required = true, dataType = "int"),
                @ApiImplicitParam(name = "user", value = "用户实体json", required = true, dataType = "User")
        })
        @PutMapping("/{id}")
        public String update(@RequestBody User user, @PathVariable Integer id){ 
            User u = userMap.get(id);
            u.setName(user.getName()).setAge(user.getAge());
            userMap.put(id, u);
            return SUCCESS;
        }
    }

## 访问接口文档 ##

启动服务，访问`http://localhost:8080/swagger-ui.html`：

点击user-controller进入接口调试，点击对应功能右上角的`Try it out`进入调试

1.  添加用户（编写号json后，点击下方的Execute执行）：![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0UwOTYyMDEyNg_size_16_color_FFFFFF_t_70 1]
2.  查询list：![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0UwOTYyMDEyNg_size_16_color_FFFFFF_t_70 2]
