黑豹程序员-SpringBoot中整合knife4j接口文档

1、Knife介绍

2、坐标

        <dependency>
            <groupId>com.github.xiaoymin</groupId>
            <artifactId>knife4j-spring-boot-starter</artifactId>
            <version>2.0.7</version>
        </dependency>

3、和SpringBoot整合

package com.hello.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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;
import springfox.documentation.swagger2.annotations.EnableSwagger2WebMvc;

@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.hello.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API文档")
                .description("这是一个示例API文档")
                .version("1.0")
                .build();
    }
}

4、和SpringMVC整合

package com.hello.config;

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

/**
 * @version v1.0 创建时间：13:38
 * @author: 作者：陈子枢
 * @web CSDN：https://blog.csdn.net/nutony
 * @description 描述：放行Knife4j请求
 */
@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

5、使用Swagger注解

package com.hello.controller;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

import java.util.List;

/**
 * @version v1.0 创建时间：13:04
 * @author: 作者：陈子枢
 * @web CSDN：https://blog.csdn.net/nutony
 * @description 描述：
 */
@RestController
@Api(tags = "用户管理")
public class ApiController {

    @ApiOperation("获取用户列表")
    @PostMapping("/user/list")
    public List getUserList(){
        return null;
    }

    @ApiOperation("获取用户名")
    @GetMapping("/user/{name}")
    public String getName(@PathVariable String name){
        return name;
    }
}
