ylb-知识点2-Swagger

1、ylb

1.1 Swagger配置类

在web模块settings包,创建SwaggerConfigruationSettinngs配置类:

package com.bjpowernode.front.settings;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

@Configuration
public class SwaggerConfigruationSettinngs {

    //创建Docket对象
    @Bean
    public Docket docket(){
        //1创建Docket对象
        Docket docket = new Docket(DocumentationType.SWAGGER_2);

        //2创建Api信息, 接口文档的总体描述
        ApiInfo apiInfo = new ApiInfoBuilder()
                .title("动力节点金融项目")
                .version("1.0")
                .description("前后端分离的项目,前端Vue,后端Spring Boot + Dubbo分布式项目")
                .build();

        //3.设置使用ApiInfo
        docket = docket.apiInfo(apiInfo);

        //4.设置参与文档生成的包
        docket = docket.select().apis(RequestHandlerSelectors.
                     basePackage("com.bjpowernode.front.controller")).build();

        return docket;

    }
}

1.2 启动类添加注解

在web模块上的启动类上添加注解:

//启动swagger 和 ui
@EnableSwaggerBootstrapUI
@EnableSwagger2
package com.bjpowernode.front;

import com.bjpowernode.common.util.JwtUtil;
import com.github.xiaoymin.swaggerbootstrapui.annotations.EnableSwaggerBootstrapUI;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

//启动swagger 和 ui
@EnableSwaggerBootstrapUI
@EnableSwagger2
//启动dubbo服务
@EnableDubbo
@SpringBootApplication
public class MicrWebApplication {

	@Value("${jwt.secret}")
	private String secertKey;
	//创建JwtUtil
	@Bean
	public JwtUtil jwtUtil(){
		JwtUtil jwtUtil = new JwtUtil(secertKey);
		return jwtUtil;
	}

	public static void main(String[] args) {
		SpringApplication.run(MicrWebApplication.class, args);
	}

}

1.3 配置文件application.yml

在web模块下的配置文件application.yml中:
MVC框架中路径匹配的设置,使用的匹配策略是Ant Path Matcher
详见Spring路径匹配器AntPathMatcher

spring:
  application:
    name: micr-web
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher
  redis:
    host: localhost
    port: 6379

#端口号
server:
  port: 8000
  servlet:
    context-path: /api
    encoding:
      enabled: true
      charset: utf-8
      force: true

#dubbo配置
dubbo:
  registry:
    address: zookeeper://localhost:2181
  scan:
    base-packages: com.bjpowernode.front
  consumer:
    check: false
    timeout: 50000
    retries: 0

#短信配置
jdwx:
  sms:
    url: https://way.jd.com/chuangxin/dxjk
    appkey: 3680fa919b771148da626bbcbd459475
    content: 【大富科技】你的验证码是:%s,3分钟内有效,请勿泄露给他人
    login-text: 【大富科技】登录验证码是:%s,3分钟内有效,请勿泄露给他人
  realname:
    url: https://way.jd.com/youhuoBeijing/test
    appkey: 3680fa919b771148da626bbcbd459475

jwt:
  secret: 342903934cb944808920b642616b3e76

2、reggie

2.1 Swagger配置类

在config包下,WebMvcConfig配置类添加:

  • 1、注解@EnableSwagger2和@EnableKnife4j
  • 2、添加Docket、ApiInfo,描述接口文档信息
  • 3、设置静态资源(WebMvcConfig中)
  • 4、LoginCheckFilter(设置不需要处理的路径)
package com.itheima.reggie.config;

        messageConverter.setObjectMapper(new JacksonObjectMapper());
        //将上面的消息转换器对象追加到mvc框架的转换器集合中
        converters.add(0,messageConverter);
    }

    @Bean
    public Docket createRestApi() {
        // 文档类型
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.itheima.reggie.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("瑞吉外卖")
                .version("1.0")
                .description("瑞吉外卖接口文档")
                .build();
    }
}
