之前我的项目中整合Swagger都是间接通过依赖springfox-swagger
、springfox-swagger-ui
两个jar包来实现的,最近发现springfox 3.0.0版本曾经有了本人的SpringBoot Starter,应用起来更符合SpringBoot我的项目,十分不便,举荐给大家!
应用官网Starter
咱们先应用官网Starter来整合Swagger看看是否够简略!
- 首先在
pom.xml
中增加springfox官网Swagger依赖;
<!--springfox swagger官网Starter-->
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-boot-starter</artifactId> <version>3.0.0</version></dependency>
- 增加Swagger的Java配置,配置好Api信息和须要生成接口文档的类扫描门路即可;
/** * Swagger2API文档的配置 */@Configurationpublic class Swagger2Config { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("com.mybatis.plus")) .paths(PathSelectors.any()) .build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("SwaggerUI演示") .description("Spring Boot Swagger2 构建把把智能") .contact(new Contact("wlb", null, null)) .version("1.0") .build(); }}
注:
这里不再须要 @EnableSwagger2
注解
- 拜访API文档信息,拜访地址:http://localhost:8080/swagger-ui/
- 两步即可搞定SpringBoot集成Swagger,是不是很简略!
与之前版本相比
之前咱们应用的是springfox 2.9.2版本,接下来比照下3.0.0的SpringBoot Starter应用,看看有何不同!
- 旧版本须要依赖
springfox-swagger2
和springfox-swagger-ui
两个配置,新版本一个Starter就搞定了,而且之前的版本如果不应用新版本的swagger-models
和swagger-annotations
依赖,拜访接口会呈现NumberFormatException
问题;
<dependencies> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <exclusions> <exclusion> <groupId>io.swagger</groupId> <artifactId>swagger-annotations</artifactId> </exclusion> <exclusion> <groupId>io.swagger</groupId> <artifactId>swagger-models</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> </dependency> <!--解决Swagger 2.9.2版本NumberFormatException--> <dependency> <groupId>io.swagger</groupId> <artifactId>swagger-models</artifactId> <version>1.6.0</version> </dependency> <dependency> <groupId>io.swagger</groupId> <artifactId>swagger-annotations</artifactId> <version>1.6.0</version> </dependency></dependencies>
- 新版本去除了一些第三方依赖,包含
guava
,之前应用旧版本时就因为guava
版本问题导致过依赖抵触,具体能够看下《给Swagger降级了新版本,没想到竟然有这么多坑!》; - 新版本和旧版本文档拜访门路产生了变动,新版本为:http://localhost:8080/swagger-ui/ ,旧版本为:http://localhost:8080/swagger-ui.html
- 新版本中新增了一些SpringBoot配置,
springfox.documentation.enabled
配置能够管制是否启用Swagger文档生成性能; - 比如说咱们只想在
dev
环境下启用Swagger文档,而在prod
环境下不想启用,旧版本咱们能够通过@Profile
注解实现;
@Configuration@EnableSwagger2@Profile(value = {"dev"})public class Swagger2Config { }
- 新版本咱们在SpringBoot配置文件中进行配置即可,
springfox.documentation.enabled
在application-dev.yml
配置为true,在application-prod.yml
中配置为false。
整合Spring Security应用
咱们常常会在我的项目中应用Spring Security实现登录认证,接下来咱们来讲下如何应用Swagger整合Spring Security,实现拜访须要登录认证的接口。
- 如何拜访须要登录认证的接口?只需在拜访接口时增加一个非法的
Authorization
申请头即可,上面是Swagger相干配置;
/** * Swagger2API文档的配置 */@Configurationpublic class Swagger2Config { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("com.mybatis.plus")) .paths(PathSelectors.any()) .build() //增加登录认证 .securitySchemes(securitySchemes()) .securityContexts(securityContexts()); } //构建 api文档的详细信息函数 private ApiInfo apiInfo() { return new ApiInfoBuilder() //页面题目 .title("Spring Boot Swagger2 构建把把智能") //条款地址 .termsOfServiceUrl("http://despairyoke.github.io/") .contact(new Contact("wlb", null, null)) .version("1.0") //形容 .description("API 形容") .build(); } private List<SecurityScheme> securitySchemes() { //设置申请头信息 List<SecurityScheme> result = new ArrayList<>(); ApiKey apiKey = new ApiKey("Authorization", "Authorization", "header"); result.add(apiKey); return result; } private List<SecurityContext> securityContexts() { //设置须要登录认证的门路 List<SecurityContext> result = new ArrayList<>(); result.add(getContextByPath("/brand/.*")); return result; } private SecurityContext getContextByPath(String pathRegex) { return SecurityContext.builder() .securityReferences(defaultAuth()) .forPaths(PathSelectors.regex(pathRegex)) .build(); } private List<SecurityReference> defaultAuth() { List<SecurityReference> result = new ArrayList<>(); AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything"); AuthorizationScope[] authorizationScopes = new AuthorizationScope[1]; authorizationScopes[0] = authorizationScope; result.add(new SecurityReference("Authorization", authorizationScopes)); return result; }}
- 咱们须要在Spring Security中配置好Swagger动态资源的无受权拜访,比方首页拜访门路
/swagger-ui/
;
package com.spring.security.demo.config;import com.spring.security.demo.security.JwtAuthenticationFilter;import com.spring.security.demo.security.JwtAuthenticationProvider;import com.spring.security.demo.security.JwtLoginFilter;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.http.HttpMethod;import org.springframework.security.authentication.AuthenticationManager;import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;import org.springframework.security.web.authentication.logout.HttpStatusReturningLogoutSuccessHandler;@Configuration@EnableWebSecurity@EnableGlobalMethodSecurity(prePostEnabled = true)/** * 对SpringSecurity的配置的扩大,反对自定义白名单资源门路和查问用户逻辑 */public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private UserDetailsService userDetailsService; @Override public void configure(AuthenticationManagerBuilder auth) throws Exception { // 如果间接定制UserDetailsService ,而不自定义 AuthenticationProvider,能够间接在配置文件 WebSecurityConfig 中这样配置。 // 指定自定义的获取信息获取服务// auth.userDetailsService(userDetailsService); // 应用自定义登录身份认证组件----> 指定了自定义身份认证组件 JwtAuthenticationProvider,并注入 UserDetailsService auth.authenticationProvider(new JwtAuthenticationProvider(userDetailsService)); } @Override protected void configure(HttpSecurity http) throws Exception { // 禁用 csrf, 因为应用的是JWT,咱们这里不须要csrf http.cors().and().csrf() .disable() .sessionManagement()// 基于token,所以不须要session .sessionCreationPolicy(SessionCreationPolicy.STATELESS) .and() .authorizeRequests() .antMatchers(HttpMethod.GET, // 容许对于网站动态资源的无受权拜访 "/", "/swagger-ui/", "/*.html", "/favicon.ico", "/**/*.html", "/**/*.css", "/**/*.js", "/swagger-resources/**", "/v2/api-docs/**" ) .permitAll() .antMatchers("/login")// 对登录注册要容许匿名拜访 .permitAll() .antMatchers(HttpMethod.OPTIONS)//跨域申请会先进行一次options申请 .permitAll() .anyRequest()// 除下面外的所有申请全副须要鉴权认证 .authenticated(); // 退出登录处理器 http.logout().logoutSuccessHandler(new HttpStatusReturningLogoutSuccessHandler()); // 开启登录认证流程过滤器----> 指定了登录认证流程过滤器 JwtLoginFilter,由它来触发登录认证// http.addFilterBefore(new JwtLoginFilter(authenticationManager()), UsernamePasswordAuthenticationFilter.class); // 访问控制时登录状态查看过滤器----> 指定了访问控制过滤器 JwtAuthenticationFilter,在受权时解析令牌和设置登录状态 http.addFilterBefore(new JwtAuthenticationFilter(authenticationManager()), UsernamePasswordAuthenticationFilter.class); } //初始化authenticationManager @Bean @Override public AuthenticationManager authenticationManager() throws Exception { return super.authenticationManager(); }}
- 调用登录接口获取token,账号密码为
admin:123456
; - 点击
Authorize
按钮后输出Authorization
申请头,之后就能够拜访须要登录认证的接口了。
总结
Swagger官网Starter解决了之前整合Swagger的一系列问题,简化了SpringBoot整合Swagger的过程,应用起来更加不便了。同时对于一些简单的配置应用根本没有变动,一些之前的应用形式仍然能够应用!
