springboot 集成完整的swagger2
springboot 在集成swagger中会不会遇到各种问题:
1、swagger 进行接口鉴权(比如设置header的token,接口进行拦截处理)。
2、swagger 进行实体属性解析(pojo类的属性注解无法解析)。
3、swagger 进行响应码统一(code状态吗标识、200响应成功,响应体解析)。
4、swagger 设置接口共用参数(统一每个接口都存在的参数)。
以下是解决问题配置信息
一、引入依赖包
使用之前请更新或直接引用该版本依赖包
更新版本地址:接口依赖jar https://mvnrepository.com/artifact/io.springfox/springfox-swagger2
ui 依赖jar https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.9.2</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.9.2</version> </dependency>
二、创建swagger 配置类
1、全局参数
2、全局响应参数,每个接口都存在响应值,方便沟通
3、设置安全认证
点击 authorize 按钮输入验证信息,则每次调试接口都会传响应的信息
废话少说!上配置代码
package com.example.config.swagger; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Profile; import org.springframework.web.bind.annotation.RequestMethod; import springfox.documentation.builders.*; import springfox.documentation.schema.ModelRef; import springfox.documentation.service.*; import springfox.documentation.spi.DocumentationType; import springfox.documentation.spring.web.plugins.Docket; import springfox.documentation.swagger2.annotations.EnableSwagger2; import java.util.ArrayList; import java.util.List; /** * * @author niunafei * * @Profile 注解 标识加载在dev和test文件使用 */ @Configuration @EnableSwagger2 //@Profile({"dev", "test"}) public class SwaggerConfig { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2).groupName("spring-test-interface") //加载配置信息 .apiInfo(apiInfo()) //设置全局参数 .globalOperationParameters(globalParamBuilder()) //设置全局响应参数 .globalResponseMessage(RequestMethod.GET,responseBuilder()) .globalResponseMessage(RequestMethod.POST,responseBuilder()) .globalResponseMessage(RequestMethod.PUT,responseBuilder()) .globalResponseMessage(RequestMethod.DELETE,responseBuilder()) .select() //加载swagger 扫描包 .apis(RequestHandlerSelectors.basePackage("com.example")) .paths(PathSelectors.any()).build() //设置安全认证 .securitySchemes(security()); } /** * 获取swagger创建初始化信息 * @return */ private ApiInfo apiInfo() { Contact contact = new Contact("niunafei", "", "niunafei0315@163.com"); return new ApiInfoBuilder().title("swagger 测试文档").description("dev by niunafei").contact(contact) .version("1.0.0").build(); } /** * 安全认证参数 * @return */ private List<ApiKey> security() { List<ApiKey> list=new ArrayList<>(); list.add(new ApiKey("token", "token", "header")); return list; } /** * 构建全局参数列表 * @return */ private List<Parameter> globalParamBuilder(){ List<Parameter> pars = new ArrayList<>(); pars.add(parameterBuilder("token","令牌","string","header",false).build()); return pars; } /** * 创建参数 * @return */ private ParameterBuilder parameterBuilder(String name,String desc,String type ,String parameterType,boolean required) { ParameterBuilder tokenPar = new ParameterBuilder(); tokenPar.name(name).description(desc).modelRef(new ModelRef(type)).parameterType(parameterType).required(required).build(); return tokenPar; } /** * 创建全局响应值 * @return */ private List<ResponseMessage> responseBuilder() { List<ResponseMessage> responseMessageList = new ArrayList<>(); responseMessageList.add(new ResponseMessageBuilder().code(200).message("响应成功").build()); responseMessageList.add(new ResponseMessageBuilder().code(500).message("服务器内部错误").build()); return responseMessageList; } }
以上代码中 @Profile({"dev", "test"})注解是在开发环境和测试环境的时候加载该类,线上生产环境为安全不建议创建swagger的bean
三、引入配置文件,并且配置好扫描类,但是仍然不能访问swagger 页面,这时候请考虑springboot的mvc指定访问路径
addResourceHandlers 方法中已经指定swagger-ui访问页的路径
同时该配置中处理了mvc 跨域的问题
addCorsMappings 方法中是在拦截 addInterceptors 方法执行后进行的跨域设置
corsFilter可以解决所有跨域问题
package com.example.config.mvc; //import com.example.config.interceptor.LoginInterceptor; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.cors.CorsConfiguration; import org.springframework.web.cors.UrlBasedCorsConfigurationSource; import org.springframework.web.filter.CorsFilter; import org.springframework.web.servlet.config.annotation.CorsRegistry; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport; /** * @author niunafei * @function * @email niunafei0315@163.com * @date 2019/6/28 下午12:28 */ @Configuration public class WebMvcConfigurerAdapter extends WebMvcConfigurationSupport { // @Autowired // private LoginInterceptor loginInterceptor; @Override public void addInterceptors(InterceptorRegistry registry) { // 添加拦截接口请求处理, // registry.addInterceptor(loginInterceptor).addPathPatterns("/api/**"); } @Override protected void addResourceHandlers(ResourceHandlerRegistry registry) { //定向swagger 位置 registry.addResourceHandler("/**").addResourceLocations("classpath:/static/"); registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/"); registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/"); } /** * 拦截后的跨域解决 * * @param registry */ @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**").allowCredentials(true).allowedHeaders("*").allowedOrigins("*").allowedMethods("GET", "POST", "PUT", "OPTIONS"); } /** * 处理拦截前处理检测 授权跨域问题 * * @return */ @Bean public CorsFilter corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); source.registerCorsConfiguration("/**", corsConfig()); return new CorsFilter(source); } /** * @return */ private CorsConfiguration corsConfig() { CorsConfiguration corsConfiguration = new CorsConfiguration(); // 请求常用的三种配置,*代表允许所有,当时你也可以自定义属性(比如header只能带什么,只能是post方式等等) corsConfiguration.addAllowedOrigin("*"); corsConfiguration.addAllowedHeader("*"); corsConfiguration.addAllowedMethod("*"); corsConfiguration.setAllowCredentials(true); corsConfiguration.setMaxAge(3600L); return corsConfiguration; } }
四、swagger 返回扫描的问题
接口层请使用泛型返回,个人定义的统一返回类
ApiModel是生成swagger时扫描的实体注解
ApiModelProperty 是属性注解
ApiHttpCode 是一个响应值的枚举类
package com.example.config.response; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; /** * @author niunafei * @function * @email niunafei0315@163.com * @date 2019/6/28 下午2:00 */ @ApiModel() public class ApiResult<T> { private static final Object RESULT_OBJECT=new Object(); @ApiModelProperty(value = "编码", name = "code", dataType = "int", example = "200") private Integer code; @ApiModelProperty(value = "提示", name = "msg", dataType = "string", example = "success") private String msg; @ApiModelProperty(value = "内容", name = "data", dataType = "t") private T data; public ApiResult() { } public ApiResult(ApiHttpCode code, T data) { this.code = code.getCode(); this.msg = code.getDesc(); this.data = data; } public ApiResult(Integer code, String msg, T data) { this.code = code; this.msg = msg; this.data = data; } public static ApiResult<Object> ok() { return ApiResult.ok(ApiHttpCode.SUCCESS, RESULT_OBJECT); } public static <T> ApiResult<T> ok(T data) { return ApiResult.ok(ApiHttpCode.SUCCESS, data); } public static <T> ApiResult<T> ok(ApiHttpCode code, T data) { return ApiResult.ok(code.getCode(), code.getDesc(), data); } public static <T> ApiResult<T> ok(Integer code, String msg, T data) { return new ApiResult(code, msg, data); } public static ApiResult<Object> error() { return ApiResult.error(ApiHttpCode.ERROR, new Object()); } public static <T> ApiResult<T> error(T data) { return ApiResult.error(ApiHttpCode.ERROR, data); } public static <T> ApiResult<T> error(ApiHttpCode code) { return ApiResult.error(code.getCode(),code.getDesc(),null); } public static <T> ApiResult<T> error(ApiHttpCode code, T data) { return ApiResult.error(code.getCode(), code.getDesc(), data); } public static <T> ApiResult<T> error(Integer code, String msg) { return ApiResult.error(code, msg, null); } public static <T> ApiResult<T> error(Integer code, String msg, T data) { return new ApiResult(code, msg, data); } public Integer getCode() { return code; } public String getMsg() { return msg; } public T getData() { return data; } }
ApiHttpCode枚举类
package com.example.config.response; /** * @author niunafei * @function * @email niunafei0315@163.com * @date 2019/6/28 下午2:02 */ public enum ApiHttpCode { /** * 响应成功 */ SUCCESS(200, "OK"), /** * 服务器异常 */ ERROR(500, "ERROR"), /** * 未授权访问 */ UNAUTHORIZED(401, "访问未授权"); private int code; private String desc; ApiHttpCode(int code, String desc) { this.code = code; this.desc = desc; } public int getCode() { return code; } public String getDesc() { return desc; } public static ApiHttpCode valueOf(int value) { for (ApiHttpCode role : ApiHttpCode.values()) { if (role.code == value) { return role; } } return null; } }
五、接口层引用
@Api注解添加
接口方法上添加@ApiOperation 才可以生成文档
@ApiImplicitParams 用来定义接口参数,并指定描述的,
@ApiResponses 用来定义添加额外的响应值,与配置类中的全局响应功能一致。
访问接口页面 http://localhost:8888/spring-demo/swagger-ui.html
访问格式:http://IP地址或域名:端口/应用名称/swagger-ui.html
无关后话,与swagger 无关:授权检测的创建继承HandlerInterceptorAdapter 方法
package com.example.config.interceptor; import org.springframework.stereotype.Component; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.handler.HandlerInterceptorAdapter; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * @author niunafei * @function * @email niunafei0315@163.com * @date 2019/6/28 下午12:31 */ @Component public class LoginInterceptor extends HandlerInterceptorAdapter { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { //未开启权限检测 跳过 return true; } @Override public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception { } @Override public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception { } }
