swagger2是一款帮助我们生成restful接口细节记录信息的工具。

引入Swagger2

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.2.2</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.2.2</version>
</dependency>

创建配置类

Application.java的同级创建Swagger2.java

@Configuration //标注为配置类
@EnableSwagger2 //启动Swagger2
public class Swagger2 {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.didispace.web"))
                .paths(PathSelectors.any())
                .build();
    }

//基本信息
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("标题")
                .description("介绍")
                .termsOfServiceUrl("url")
                .contact("name")
                .version("1.0")
                .build();
    }

}

丰富文档内容

• @ApiOperation给api增加说明
• @ApiImplicitParams包裹多个参数注解信息
• @ApiImplicitParam参数注解信息

@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<Long, User> users = Collections.synchronizedMap(new HashMap<Long, User>());

    @ApiOperation(value="获取用户列表", notes="")
    @RequestMapping(value={""}, method=RequestMethod.GET)
    public List<User> getUserList() {
        List<User> r = new ArrayList<User>(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";
    }

}

启动springBoot，访问http://localhost:8080/swagger-ui.html就能看到详细信息。

调试API

进入Swagger2的web界面，点击进入api,里面有调试api的按钮，并且黄色区域有参数的模板。

生产环境禁用

swagger2:
  enable: false
