Spring boot/swagger

添加pom依赖:


    io.springfox
    springfox-swagger2
    2.2.2


    io.springfox
    springfox-swagger-ui
    2.2.2

创建Swagger2配置类:
在Application.java同级创建Swagger2的配置类Swagger2。

@Configuration
@EnableSwagger2
public class Swagger2 {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.sboot.web"))
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("My RESTful APIs")
                .description("用Swagger2构建RESTful APIs")
                .termsOfServiceUrl("yourUrl")
                .contact("zzhblh")
                .version("1.0")
                .build();
    }
}

如上代码所示,通过@Configuration注解,让Spring来加载该类配置。再通过@EnableSwagger2注解来启用Swagger2。
再通过createRestApi函数创建Docket的Bean之后,apiInfo()用来创建该Api的基本信息(这些基本信息会展现在文档页面中)。select()函数返回一个ApiSelectorBuilder实例用来控制哪些接口暴露给Swagger来展现,本例采用指定扫描的包路径来定义,Swagger会扫描该包下所有Controller定义的API,并产生文档内容(除了被@ApiIgnore指定的请求)。

Controller:
通过@ApiOperation注解来给API增加说明、通过@ApiImplicitParams
,@ApiImplicitParam注解来给参数增加说明。

@RestController
@RequestMapping(value="/users")     // 通过这里配置使下面的映射都在/users下,可去除
public class UserController {
    static Map users = Collections.synchronizedMap(new HashMap());
    @ApiOperation(value="获取用户列表", notes="")
    @RequestMapping(value={""}, method=RequestMethod.GET)
    public List getUserList() {
        List r = new ArrayList(users.values());
        return r;
    }
    @ApiOperation(value="创建用户", notes="根据User对象创建用户")
    @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")
    @RequestMapping(value="", method=RequestMethod.POST)
    public String postUser(@RequestBody User user) {
        users.put(user.getId(), user);
        return "success";
    }
    @ApiOperation(value="获取用户详细信息", notes="根据url的id来获取用户详细信息")
    @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
    @RequestMapping(value="/{id}", method=RequestMethod.GET)
    public User getUser(@PathVariable Long id) {
        return users.get(id);
    }
    @ApiOperation(value="更新用户详细信息", notes="根据url的id来指定更新对象,并根据传过来的user信息来更新用户详细信息")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long"),
            @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")
    })
    @RequestMapping(value="/{id}", method=RequestMethod.PUT)
    public String putUser(@PathVariable Long id, @RequestBody User user) {
        User u = users.get(id);
        u.setName(user.getName());
        u.setAge(user.getAge());
        users.put(id, u);
        return "success";
    }
    @ApiOperation(value="删除用户", notes="根据url的id来指定删除对象")
    @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
    @RequestMapping(value="/{id}", method=RequestMethod.DELETE)
    public String deleteUser(@PathVariable Long id) {
        users.remove(id);
        return "success";
    }
}
