SpringBoot项目引入Swagger接口文档

一、在项目中引入Swagger依赖

<!--swagger-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

        <dependency>
            <groupId>com.github.xiaoymin</groupId>
            <artifactId>swagger-bootstrap-ui</artifactId>
            <version>1.9.6</version>
        </dependency>

二、Swagger配置

  1、新建两个类，分别为SwaggerProperties  SwaggerConfiguration

  2.SwaggerProperties类的内容

package com.example.book.config.swagger.properties;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "swagger")
@Data
@AllArgsConstructor
@NoArgsConstructor
public class SwaggerProperties {
    
    //标题
    private String title;
    //描述
    private String description;
    //版本
    private String version;
    //作者
    private String author;
}

3.SwaggerConfiguration配置内容

package com.example.book.config.swagger;


import com.example.book.config.swagger.properties.SwaggerProperties;
import io.swagger.annotations.ApiOperation;
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.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import javax.annotation.Resource;

@Configuration
@EnableSwagger2
public class SwaggerConfiguration{

    @Resource
    private SwaggerProperties swaggerProperties;

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("接口文档")
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build()
                //是否使用默认响应消息
                .useDefaultResponseMessages(false);
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(swaggerProperties.getTitle())
                .description(swaggerProperties.getDescription())
                .contact(new Contact(swaggerProperties.getAuthor(), "", ""))
                .version(swaggerProperties.getVersion())
                .build();
    }

}

代码的一些解释如下

 4.在application.yml中配置title，等

swagger:
  title: "项目相关服务说明文档"
  description: "作者很懒，什么也没下"
  version: "1.0"
  author: "thd"

三、在Controller中测试Swagger能否正常使用，写一个接口

package com.example.book.controller;


import com.example.book.service.IBookService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.awt.print.Book;
import java.util.List;

@RestController
@Api(tags = {"图书管理控制器"})
@RequestMapping("/book")
@Slf4j
public class BookController {

    @Resource
    IBookService bookService;

    @GetMapping("/getAll")
    @ApiOperation(value = "获取所有-book",notes = "获取所有-book")
    public List<Book> getAll(){
        return bookService.getAll();
    }


}

 五、访问http://localhost:4399/doc.html，此地址为Swagger自动生成，4399为自己设置的server.port=4399

 完成！
