SwaggerConfig配置

代码示例：

package com.xxx;【修改路径】

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.ParameterBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.schema.ModelRef;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Parameter;
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;

/**
 * Swagger2的接口配置

 * @author gxl
 */
@Configuration
@EnableSwagger2
@EnableKnife4j
public class SwaggerConfig {

    /**
     * 是否开启swagger
     */
    @Value("${swagger.enabled}")
    private boolean enabled;

    /**
     * 创建API
     */
    @Bean
    public Docket createRestApi() {
        ParameterBuilder ticketPar = new ParameterBuilder();
        List<Parameter> pars = new ArrayList<Parameter>();
        //Token 以及Authorization 为自定义的参数，session保存的名字是哪个就可以写成那个
        ticketPar.name("Authorization").description("授权")
                .modelRef(new ModelRef("string")).parameterType("header")
                //header中的ticket参数非必填，传空也可以
                .required(false).build();
        //根据每个方法名也知道当前方法在设置什么参数
        pars.add(ticketPar.build());
        return new Docket(DocumentationType.SWAGGER_2)
                .enable(enabled)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.gxl"))
                .paths(PathSelectors.any())

    }

    /**
     * 添加摘要信息
     */
    private ApiInfo apiInfo() {
        // 用ApiInfoBuilder进行定制
        return new ApiInfoBuilder()
                // 设置标题
                .title("boot项目_接口文档")
                // 描述
                .description("boot项目服务")
                // 版本
                .version("版本号:" + "1.0")
                .build();
    }
}

拦截器配置

代码示例：

package com.xxx;【修改路径】

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

/**
 *  拦截器配置
 * @author gxl
 */
@Configuration
public class WebMvcConfigurer extends WebMvcConfigurationSupport {

    /**
     * 发现如果继承了WebMvcConfigurationSupport，则在yml中配置的相关内容会失效。 需要重新指定静态资源
     *
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations(
                "classpath:/static/");
        registry.addResourceHandler("swagger-ui.html").addResourceLocations(
                "classpath:/META-INF/resources/");
        registry.addResourceHandler("doc.html").addResourceLocations(
                "classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations(
                "classpath:/META-INF/resources/webjars/");
        super.addResourceHandlers(registry);
    }
}
