Swagger使用
1. Swagger UI
按以下步骤配置,项目启动后访问:
1.1 添加依赖
io.springfox springfox-swagger2 2.2.2 io.springfox springfox-swagger-ui 2.2.2
1.2 配置类
@Configuration @EnableSwagger2 public class Swagger2 { public static final String SWAGGER_SCAN_BASE_PACKAGE = "abc.boot.examples.web"; public static final String VERSION = "1.0.0"; @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage(SWAGGER_SCAN_BASE_PACKAGE))//api接口包扫描路径 .paths(PathSelectors.any())//可以根据url路径设置哪些请求加入文档,忽略哪些请求 .build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("Swagger2 接口文档示例")//设置文档的标题 .description("更多内容请关注:http://www.abc.com")//设置文档的描述->1.Overview .version(VERSION)//设置文档的版本信息-> 1.1 Version information .contact(new Contact("ABC Boot", "http://www.abc.comt", ""))//设置文档的联系方式->1.2 Contact information .termsOfServiceUrl("www.abc.com")//设置文档的License信息->1.3 License information .build(); } }
1.3 注解使用
@ApiOperation
@ApiOperation(value="获取用户列表", notes="获取所有用户列表",produces = "application/json") @RequestMapping(value="/users", method= RequestMethod.GET) public ListgetUserList() { List r = new ArrayList (users.values()); return r; }
@ApiResponses
@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",produces = "application/json")// ApiResponses 增加返回结果的描述 @ApiResponses(value = { @ApiResponse(code = 405,message = "Invalid input",response = Integer.class)}) (1) @ApiImplicitParam(name = "id",value = "用户ID",dataType = "int",paramType = "path") (2) @RequestMapping(value="/users/{id}", method= RequestMethod.GET) public User getUser(@PathVariable Integer id) { return users.get(id); }
(1) 在默认Response的基础上增加新的Response说明
(2) 使用ApiImplicitParam描述接口参数@ApiImplicitParams
@ApiOperation(value="更新用户名称", notes="更新指定用户的名称")@RequestMapping(value="/users/{id}", method= RequestMethod.POST) @ApiImplicitParams({ (1) @ApiImplicitParam(name = "id",value = "用户ID",paramType = "path",dataType = "int"), (2) @ApiImplicitParam(name = "userName",value = "用户名称",paramType = "form",dataType = "string") }) public void updateUserName(@PathVariable Integer id,@RequestParam String userName){ User u = users.get(id); u.setName(userName); }
(1) 使用ApiImplicitParams描述多个参数
(2) 使用ApiImplicitParam时,需要指定paramType,这样也便于swagger ui 生成参数的输入格式。paramType 有五个可选值 : path, query, body, header, form
@ApiParam
@ApiOperation(value="创建用户-传递简单对象", notes="传递简单对象",produces = "application/json")@RequestMapping(value="/users-1", method= RequestMethod.POST) //可以不加ApiParam注解,需要给参数添加描述时可以使用这个注解,或者使用ApiImplicitParams注解 (1) public Map postUser(@RequestParam String userName,@ApiParam("地址") @RequestParam(required = false) String address) { User user = new User(); user.setId(Math.round(10)); user.setName(userName); user.setAddress(address); users.put(user.getId(), user); return ImmutableMap.of("user",user); }
(1) 使用ApiParam描述接口参数
ApiImplicitParam 与 ApiParam 的区别
ApiImplicitParam: This is the only way to define parameters when using Servlets or other non-JAX-RS environments.- 对Servlets或者非 JAX-RS的环境,只能使用 ApiImplicitParam。
- 在使用上,ApiImplicitParam比ApiParam具有更少的代码侵入性,只要写在方法上就可以了,但是需要提供具体的属性才能配合swagger ui解析使用。
- ApiParam只需要较少的属性,与swagger ui配合更好。
传递复杂对象 By ModelAttribute
@ApiOperation(value="创建用户-传递复杂对象", notes="传递复杂对象DTO, url参数拼接",produces = "application/json")@RequestMapping(value="/users-2", method= RequestMethod.POST) //传递对象推荐使用ModelAttribute注解 public Map postUser2(@ModelAttribute User user) { (1) users.put(user.getId(),user); return ImmutableMap.of("user",user); }
(1) ModelAttribute 是Spring mvc的注解,这里Swagger可以解析这个注解,获得User的属性描述
@ApiModel
@ApiModel(value = "User", description = "用户对象")public class User { @ApiModelProperty(value = "ID") private Integer id; @ApiModelProperty(value = "姓名") private String name; @ApiModelProperty(value = "地址") private String address; @ApiModelProperty(value = "年龄",access = "hidden") private int age; @ApiModelProperty(value = "性别") private int sex; ....... }
传递复杂对象 By RequestBody
@ApiOperation(value="创建用户-传递复杂对象", notes="传递复杂对象DTO,json格式传递数据",produces = "application/json")@RequestMapping(value="/users-3", method= RequestMethod.POST) //json格式传递对象使用RequestBody注解 public User postUser3(@RequestBody User user) { users.put(user.getId(),user); return user; }
PathVariable
@ApiOperation(value="删除用户- PathVariable", notes="根据url的id来指定删除对象")@RequestMapping(value="/users/{id}", method = RequestMethod.DELETE) public void deleteUser(@PathVariable Integer id) { (1) users.remove(id); }
(1) PathVariable是Spring 的注解,对于这种简单的参数,就可以不用写ApiParam来描述接口参数。
数组的描述
@ApiOperation(value="删除用户-传递数组", notes="删除对象,传递数组")@RequestMapping(value="/users/deleteByIds", method = RequestMethod.DELETE) public void deleteUser(@ApiParam("用户ID数组") @RequestParam Integer[] ids) { (1) for (int id:ids){ users.remove(id); } }
(1) 这里用ApiParam为数组参数添加描述
1.4 可选配置
在application.properties中加入以下配置,用于设置测试请求的host,默认在swagger ui上做请求测试时都是以/users/1为路径发送请求。
如果需要改变请求的根路径,就需要配置这个参数:springfox.documentation.swagger.v2.host = yourapp.abc.com配置获取api docs json数据的请求路径 ,默认为/v2/api-docs:
springfox.documentation.swagger.v2.path = /api2. springfox-staticdocs 生成静态文档
2.1 Maven 配置
io.springfox springfox-staticdocs 2.2.2 test
2.2 生成json文件
编写Junit测试,这样在测试环节就可以将api-docs的json数据写入文档,便于下一步生成asciidoc文件。
@WebAppConfiguration@RunWith(SpringJUnit4ClassRunner.class)@SpringBootTest(classes = DemoBootApplication.class)public class Swagger2MarkupTest { @Autowired private WebApplicationContext context; private MockMvc mockMvc; @Before public void setUp() { this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context).build(); } @Test public void createSpringfoxSwaggerJson() throws Exception { String outputDir = "src/docs/json"; //将api-docs的json数据写入文件 MvcResult mvcResult = this.mockMvc.perform(get("/v2/api-docs") .accept(MediaType.APPLICATION_JSON)) .andExpect(status().isOk()) .andReturn(); MockHttpServletResponse response = mvcResult.getResponse(); String swaggerJson = response.getContentAsString(); Files.createDirectories(Paths.get(outputDir)); try (BufferedWriter writer = Files.newBufferedWriter(Paths.get(outputDir, "swagger.json"), StandardCharsets.UTF_8)) { writer.write(swaggerJson); } } }
2.3 配置Maven Plugin
配置以下两个插件:
swagger2markup-maven-plugin,该插件将json文件转为asciidocasciidoctor-maven-plugin, 该插件将asciidoc转为html/pdf执行Maven命令 : mvn swagger2markup:convertSwagger2markup process-resources
生成的html文档存储在src\main\resources\META-INF\resources\docs目录下。
