java技术：knife4j实现后端swagger文档

一、pom依赖

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>3.0.2</version>
</dependency>

lombok依赖

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.8</version>
        </dependency>

二、配置文件

package com.example.config;

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

/**
 * @author Mr.L
 * @version 1.0
 * @description TODO
 * @date 2024/3/27 11:18
 */
@Configuration
public class SwaggerConfig {
    @Bean
    public Docket docket() {
        ApiInfo apiInfo = new ApiInfoBuilder()
                .title("社区治理管理系统")
                .version("1.0")
                .description("社区治理管理系统对社区信息进行操作管理")
                .build();
        Docket docket = new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.controller"))
                .paths(PathSelectors.any())
                .build();
        return docket;
    }

    /**
     * 设置静态资源映射
     * @param registry
     */
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/doc.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

三、日志输出

package com.example;

import lombok.extern.slf4j.Slf4j;
import org.apache.jena.sparql.function.library.leviathan.log;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.core.env.Environment;

import java.net.InetAddress;
import java.net.UnknownHostException;

@Slf4j
@MapperScan("com.example.mapper")
@SpringBootApplication
public class Application {
    public static void main(String[] args) throws UnknownHostException {
        ConfigurableApplicationContext application = SpringApplication.run(Application.class, args);
        Environment env = application.getEnvironment();
        String ip = InetAddress.getLocalHost().getHostAddress();
        String port = env.getProperty("server.port");
        String context = env.getProperty("server.servlet.context-path");
        log.info("\n----------------------------------------------------------\n\t" +
                "Application Jeecg-Boot is running! Access URLs:\n\t" +
                "Local: \t\thttp://localhost:" + port + context + "/\n\t" +
                "External: \thttp://" + ip + ":" + port + context + "/\n\t" +
                "Swagger文档: \thttp://" + ip + ":" + port + context + "/doc.html\n" +
                "----------------------------------------------------------");
    }
}
