java swagger 设置token

实现Java Swagger设置Token的步骤

为了实现Java Swagger的Token设置，我们需要按照以下步骤进行操作：

接下来，我们将逐步详细介绍每个步骤的具体操作。

步骤1：导入所需的依赖库

首先，我们需要在项目的pom.xml文件中导入以下Swagger和Spring Security相关的依赖库：

<dependencies>
    <!-- Swagger 相关依赖 -->
    <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>
    
    <!-- Spring Security 相关依赖 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
</dependencies>

步骤2：配置Swagger Security

在Spring Boot的配置类中，我们需要配置Swagger Security，以定义哪些API需要受到保护，需要通过Token进行访问。

@Configuration
@EnableSwagger2
public class SwaggerConfig {
 
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build()
                .securitySchemes(Arrays.asList(apiKey()))
                .securityContexts(Arrays.asList(securityContext()));
    }
    
    private ApiKey apiKey() {
        return new ApiKey("Token Access", "token", "header");
    }
    
    private SecurityContext securityContext() {
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(PathSelectors.regex("/api/.*"))
                .build();
    }
    
    private List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Arrays.asList(new SecurityReference("Token Access", authorizationScopes));
    }
}

步骤3：实现自定义的Token验证过滤器

我们需要编写一个自定义的Token验证过滤器，用于验证请求中的Token是否有效。

@Component
public class TokenFilter extends OncePerRequestFilter {
 
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        String token = extractTokenFromRequest(request);
        
        // 验证Token是否有效，这里可以根据具体业务逻辑进行实现
        
        filterChain.doFilter(request, response);
    }
    
    private String extractTokenFromRequest(HttpServletRequest request) {
        // 从请求中提取Token，可以根据具体的Token位置进行实现
        // 这里假设Token存储在请求头的Authorization字段中
        String tokenHeader = request.getHeader("Authorization");
        if (StringUtils.hasText(tokenHeader) && tokenHeader.startsWith("Bearer ")) {
            return tokenHeader.substring(7);
        }
        return null;
    }
}

步骤4：将Token验证过滤器应用到Swagger上

最后，我们需要将自定义的Token验证过滤器应用到Swagger上，以确保Swagger在访问API时会执行Token验证。

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
 
    @Autowired
    private TokenFilter tokenFilter;
    
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .authorizeRequests()
                .antMatchers("/swagger-ui.html", "/v2/api-docs", "/swagger-resources/**", "/webjars/**").permitAll()
                .anyRequest().authenticated();
        
        http.addFilterBefore(tokenFilter, BasicAuthenticationFilter.class);
    }
    
    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs", "/configuration/ui", "/swagger-resources/**", "/configuration/security", "/swagger-ui.html", "/webjars/**");
    }
}

以上就是实现Java Swagger设置Token
