這篇文章主要介紹了SpringBoot基于Swagger2構建API文檔過程解析,文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值,需要的朋友可以參考下

一、添加依賴

<!--SpringBoot使用Swagger2構建API文檔的依賴-->
    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger2</artifactId>
      <version>2.7.0</version>
    </dependency>

    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger-ui</artifactId>
      <version>2.7.0</version>
    </dependency>

二、創(chuàng)建Swagger2配置類

package com.offcn.config;

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.EnableSwagger2;

@Configuration//表示該類為一個配置類，相當于spring中的xml配置文件
@EnableSwagger2 //開啟在線文檔
public class SwaggerConfig {

  //1.聲明 api 文檔的屬性
  private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
        .title("Spring Boot中使用Swagger2構建RESTful APIs")
        .description("優(yōu)就業(yè)")
        .termsOfServiceUrl("http://www.ujiuye.com/")
        .contact("小劉同學")
        .version("1.0")
        .build();
  }

  //配置核心配置信息
  public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2)
        .apiInfo(apiInfo())
        .select()
        .apis(RequestHandlerSelectors.basePackage("com.offcn.controller"))
        .paths(PathSelectors.any())
        .build();
  }
}

三、修改Controller 增加文檔注釋

通過@ApiOperation注解來給API增加說明

通過@ApiImplicitParams@ApiImplicitParam注解來給參數(shù)增加說明

package com.offcn.controller;

import com.offcn.dao.UserDao;
import com.offcn.entity.User;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RequestMapping("/rest")
@RestController
public class RestFulController {

  @Autowired
  private UserDao userDao;

  @GetMapping("/getUserById")
  @ApiOperation(value="查找指定id用戶信息", notes="根據(jù)id查找用戶信息")
  @ApiImplicitParams({
      @ApiImplicitParam(name = "id", value = "用戶ID", required = true, dataType = "Integer"),
  })
  public User getUserById(Integer id){
    User user = userDao.getOne(id);
    return user;
  }

  @DeleteMapping("/del")
  @ApiOperation(value="刪除指定id用戶信息", notes="根據(jù)id刪除用戶信息")
  @ApiImplicitParams({
      @ApiImplicitParam(name = "id", value = "用戶ID", required = true, dataType = "Integer"),
  })
  public String delUserById(Integer id){
    userDao.deleteById(id);
    return "success";
  }
}
