SpringBootSwagger

Java IDE SpringBoot Maven License

System : Windows 10

Intellij IDEA : Ultimate 2022.2.4

SpringBoot:2.7.6

Java : 1.8.0_333

Maven : 3.6.3

1.项目新建

首先我们先简单搭建一个简单的SpringBoot项目,如果之前没有创建过SpringBoot项目,可以参考我之前写的一篇创建SpringBoot项目的文章:使用IDEA创建SpringBoot项目 在这里插入图片描述

2.导入依赖

我们需要使用 Swagger3,需要导入对应依赖,因为 Swagger3 当前只有一个版本,所以版本也不用选了,直接使用 3.0.0 的版本

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>

</project>

3.yml配置

我们将 application.properties 的后缀名改为 yml,并创建对应测试环境的:application-test.yml,并将其中的配置信息完善,这里我们将 Swagger 的配置信息配置到 application-test.yml 中,如果使用的 SpringBoot 版本大于等于 2.6.0,则需要配置路径匹配规则,否则会报错

application.yml

# Tomcat配置
server:
  # 端口
  port: 8080

# Spring配置
spring:
  application:
    # 应用名称
    name: SpringBootSwagger
  # 配置文件
  profiles:
    # 运行环境
    active: test
  # 路径匹配机制
  mvc:
    pathmatch:
      matching-strategy: ANT_PATH_MATCHER

application-test.yml

# Document配置信息

  # 组织信息

  # 扫包路径

4.Swagger配置类

在java目录下新建 com.lijinjiang.swagger.config.property 包,创建对应的 Swagger 属性配置实体类 SwaggerProperty

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;

/**
 * @Description Swagger接口文档配置类
 * @Author 03010430
 * @ModifyDate 2023/2/13 14:36
 */
@Data
@ConfigurationProperties("swagger")
public class SwaggerProperty {
    //系统标题
    private String title;
    //分组名称
    private String groupName;
    //是否开启
    private Boolean enable = true;
    //描述信息
    private String describe;
    //版本信息
    private String version;
    //扫描路径
    private String scanPackage;
    //组织链接
    private String termsOfServiceUrl;
    //联系人名称
    private String contactName;
    //联系人url
    private String contactUrl;
    //联系人email
    private String contactEmail;
}

在 com.lijinjiang.swagger.config 包下创建 Swagger 的配置类 SwaggerConfig

import com.lijinjiang.swagger.config.property.SwaggerProperty;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
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;

import javax.annotation.Resource;
import java.sql.Timestamp;
import java.util.Date;

/**
 * @Description Swagger配置文件
 * @Author 03010430
 * @ModifyDate 2023/2/13 14:35
 */
@Configuration
@EnableConfigurationProperties(SwaggerProperty.class)
public class SwaggerConfig {

    @Resource
    private SwaggerProperty swaggerProperty;

    @Bean
    public Docket createApiDoc() {
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo())
                .groupName(swaggerProperty.getGroupName())
                .enable(swaggerProperty.getEnable())
                .select()
                .apis(RequestHandlerSelectors.basePackage(swaggerProperty.getScanPackage()))
                .build().directModelSubstitute(Timestamp.class, Date.class);
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(swaggerProperty.getTitle())
                .description(swaggerProperty.getDescribe())
                .version(swaggerProperty.getVersion())
                .termsOfServiceUrl(swaggerProperty.getTermsOfServiceUrl())
                .contact(new Contact(swaggerProperty.getContactName(), swaggerProperty.getContactUrl()
                        , swaggerProperty.getContactEmail()))
                .build();
    }
}

5.模拟案例

这里我们模拟一个用户类的增删改查操作 先创建一个 com.lijinjiang.swagger.entity 包,然后创建对应用户类 User

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.io.Serializable;
import java.sql.Timestamp;

/**
 * @Description 用户类
 * @Author 03010430
 * @ModifyDate 2023/2/13 14:52
 */
@Data
@ApiModel(description = "用户类")
public class User implements Serializable {
    private static final long serialVersionUID = 1L;
    @ApiModelProperty(value="主键ID")
    private String id;
    @ApiModelProperty(value="账号")
    private String account;
    @ApiModelProperty(value="密码")
    private String password;
    @ApiModelProperty(value="头像")
    private String avatar;
    @ApiModelProperty(value="电话")
    private String phone;
    @ApiModelProperty(value="创建时间")
    private Timestamp ctime;
}

然后创建 com.lijinjiang.swagger.controller 包,并创建用户控制类 UserController,并在里面模拟用户的增删改查操作(具体的 Mapper 和 Service 没有写)

import com.lijinjiang.swagger.common.Result;
import com.lijinjiang.swagger.entity.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

/**
 * @Description 用户控制器
 * @Author 03010430
 * @ModifyDate 2023/2/13 14:56
 */
@Api(tags = {"用户管理"})
@RestController
public class UserController {

    @ApiOperation(value = "新增用户", notes = "根据传入的数据,新增用户", produces = "application/json")
    @PostMapping("/users")
    public Result addUser(@RequestBody User user) {
        //具体业务代码
        return Result.success(null);
    }

    @ApiOperation(value = "删除用户", notes = "根据传入的id,删除对应用户")
    @DeleteMapping("/users/{id}")
    public Result deleteUser(@PathVariable("id") String id) {
        //具体业务代码
        return Result.success(null);
    }

    @ApiOperation(value = "修改用户", notes = "根据传入的数据,修改用户")
    @PutMapping("/users")
    public Result updateUser(@RequestBody User user) {
        //具体业务代码
        return Result.success(null);
    }

    @ApiOperation(value = "查询用户", notes = "根据传入的id,查找返回对应用户信息")
    @GetMapping("/users/{id}")
    public Result queryUser(@PathVariable("id") String id) {
        //具体业务代码
        return Result.success(null);
    }
}

6.项目运行

运行项目启动类(这里我将启动类名称改为了 Application) Application,然后登陆 Swagger 的 UI 界面 http://localhost:8080/swagger-ui/index.html

在这里插入图片描述 这里还可以做一些简单的测试,不过操作及显示不太友好,最好引入其他显示UI

7.引入knife4j

因为Swagger的默认UI显示的不太友好,根据市场上大家的选择,我最终选择knife4j作为Swagger的显示UI pom.xml调整,直接将引入的Swagger依赖改为引入knife4j即可

<!-- Knife4j 版本 -->
<knife4j.version>3.0.3</knife4j.version>

<!-- Knife4j 接口文档 -->
<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>${knife4j.version}</version>
</dependency>

application-test.yml 上添加 knife4j 开启增强功能

# knife4j配置
knife4j:
  # 开启增强配置
  enable: true

在这里插入图片描述 使用一段时间之后,我发现在这个系统上查看文档和测试接口都比较方便的,当然如果是使用postman测试的话,可以直接将上面的Swagger接口的url链接导入到postman,一样可以进行测试

8.项目结构

这里附上项目最终结构树,供大家参考 在这里插入图片描述
