SpringBoot整合knife4j

● knife4j是一个集 Swagger2和PoenApi为一体的增强解决方案

1. 导入依赖

<dependency>
  <groupId>com.github.xiaoymin</groupId>
  <artifactId>knife4j-spring-boot-starter</artifactId>
  <version>3.0.3</version>
</dependency>

2. 编写相关配置类

package com.feiyu.common.config;
 
 
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.Contact;
import springfox.documentation.service.Parameter;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2WebMvc;
 
import java.util.ArrayList;
import java.util.List;
 
/**
 * Created with IntelliJ IDEA.
 *
 * @Author: KeYu
 * @Package: com.feiyu.common.config
 * @Date: 2023/05/16/21:45
 * @说明:knife4j配置信息
 */
 
@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfig {
 
    @Bean
    public Docket adminApiConfig(){
        List<Parameter> pars = new ArrayList<>();
        ParameterBuilder tokenPar = new ParameterBuilder();
        tokenPar.name("token")
                .description("用户token")
                .defaultValue("")
                .modelRef(new ModelRef("string"))
                .parameterType("header")
                .required(false)
                .build();
        pars.add(tokenPar.build());
        //添加head参数end
 
        Docket adminApi = new Docket(DocumentationType.SWAGGER_2)
                .groupName("adminApi")
                .apiInfo(adminApiInfo())
                .select()
                //只显示admin路径下的页面
                .apis(RequestHandlerSelectors.basePackage("com.feiyu"))
                .paths(PathSelectors.regex("/admin/.*"))
                .build()
                .globalOperationParameters(pars);
        return adminApi;
    }
 
    private ApiInfo adminApiInfo(){
 
        return new ApiInfoBuilder()
                .title("后台管理系统-API文档")
                .description("本文档描述了后台管理系统微服务接口定义")
                .version("1.0")
                .contact(new Contact("keyu", "http://www.fkclass.top", "3111688230@qq.com"))
                .build();
    }
 
 
}

3. Controller层添加注解
   a. 方便查看

package com.feiyu.auth.controller;
 
import com.feiyu.auth.service.SysRoleService;
import com.feiyu.model.system.SysRole;
import com.feiyu.result.Result;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
import java.util.List;
 
/**
 * Created with IntelliJ IDEA.
 *
 * @Author: KeYu
 * @Package: com.feiyu.auth.controller
 * @Date: 2023/05/16/20:56
 * @说明:
 */
 
@Api("角色管理")
@RestController
@RequestMapping("/admin/system/stsRole")
public class SysRoleController {
    @Autowired
    private SysRoleService sysRoleService;
 
    @ApiOperation("查询所有角色")
    @GetMapping("/findAll")
    public Result findAll(){
        List<SysRole> list = sysRoleService.list();
        return Result.success(list);
    }
}
