1、添加相关依赖

   <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
    <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>

2、创建Swagger自动配置类


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.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.ck.demo"))
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Spring Boot中使用Swagger2构建RESTful APIs")
                .description("更多Spring Boot相关文章请关注:https://www.yuque.com/chaohen")
                .termsOfServiceUrl("https://www.yuque.com/chaohen")
                .contact("潮痕")
                .version("1.0.0")
                .build();
    }
}
  • 首先通过@Configuration注解,让Spring来加载该类配置。再通过@EnableSwagger2注解来启用Swagger2。
  • 其次通过createRestApi函数创建Docket的Bean之后,使用apiInfo()用来创建该Api的基本信息(这些基本信息会展现在文档页面中)。-
  • 再次通过select()函数返回一个ApiSelectorBuilder实例用来控制哪些接口暴露给Swagger来展现,本例采用指定扫描的包路径来定义,Swagger会扫描该包下所有Controller定义的API,并产生文档内容,这里除了被@ApiIgnore指定的请求。

实际使用:

import com.ck.demo.bean.BlogsUserInfo;
import com.ck.demo.service.UserInfoService;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import java.util.List;

@RestController
@RequestMapping("user")
public class UsreInfoController {
    @Resource
    private JdbcTemplate jdbcTemplate;

    @Autowired
    private UserInfoService userInfoService;

    @ApiOperation(value = "获取用户列表",notes = "")
    @RequestMapping(value = "/getusers",method = RequestMethod.GET)
    public Object getDbType() {
        String sql = "select * from blogs_user_info";
        RowMapper<BlogsUserInfo> rowMapper = new BeanPropertyRowMapper<BlogsUserInfo>(BlogsUserInfo.class);
        List<BlogsUserInfo> list = jdbcTemplate.query(sql, rowMapper);
        ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = servletRequestAttributes.getRequest();
        Integer times = (Integer) request.getSession().getAttribute("times");
        ;
        if (times == null) {
            times = new Integer(1);
        } else {
            times = new Integer(times.intValue() + 1);
        }
        request.getSession().setAttribute("times", times);
        System.out.println("***********************" + times);
        return list;
    }

    @ApiOperation(value = "根据用户ID获取用户信息",notes = "")
    @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
    @RequestMapping("/getId/{id}")
    public Object getUserInfoByParmityKey(@PathVariable String id) {
        BlogsUserInfo blogsUserInfo = userInfoService.getUserInfoByParmityKeyService(id);
        return blogsUserInfo;
    }

}

注解语法用例:

@Api:用在请求的类上,表示对类的说明
    tags="说明该类的作用,可以在UI界面上看到的注解"
    value="该参数没什么意义,在UI界面上也看到,所以不需要配置"
    
eg: @Api(tags = "用户信息Controller")



@ApiOperation:用在请求的方法上,说明方法的用途、作用
    value="说明方法的用途、作用"
    notes="方法的备注说明"
    
eg: @ApiOperation(value="用户登录",notes="手机号、密码都是必填!")



@ApiImplicitParams:用在请求的方法上,表示一组参数说明
    @ApiImplicitParam:用在@ApiImplicitParams注解中,指定一个请求参数的各个方面
        name:参数名
        value:参数的汉字说明、解释
        required:参数是否必须传
        paramType:参数放在哪个地方
            · header --> 请求参数的获取:@RequestHeader
            · query --> 请求参数的获取:@RequestParam
            · path(用于restful接口)--> 请求参数的获取:@PathVariable
            · body(不常用)
            · form(不常用)    
        dataType:参数类型,默认String,其它值dataType="Integer"       
        defaultValue:参数的默认值
        
 eg: @ApiImplicitParams({
        @ApiImplicitParam(name="username",value="用户名",required=true,paramType="String"),
        @ApiImplicitParam(name="password",value="密码",required=true,paramType="form"),
        @ApiImplicitParam(name="vcode",value="验证码",required=true,paramType="form",dataType="Integer")
        })



@ApiResponses:用在请求的方法上,表示一组响应
    @ApiResponse:用在@ApiResponses中,一般用于表达一个错误的响应信息
        code:数字,例如400
        message:信息,例如"请求参数没填好"
        response:抛出异常的类
        
 eg:@ApiOperation(value = "select1请求",notes = "多个参数,多种的查询参数类型")
     @ApiResponses({
        @ApiResponse(code=400,message="请求参数没填好"),
        @ApiResponse(code=404,message="请求路径没有或页面跳转路径不对")
         })

 
@ApiModel:用于响应类上,表示一个返回响应数据的信息
            (这种一般用在post创建的时候,使用@RequestBody这样的场景,
            请求参数无法使用@ApiImplicitParam注解进行描述的时候)
    @ApiModelProperty:用在属性上,描述响应类的属性

eg: 
    import io.swagger.annotations.ApiModel;
    import io.swagger.annotations.ApiModelProperty;
    import java.io.Serializable;

    @ApiModel(description= "返回响应数据")
    public class RestMessage implements Serializable{

        @ApiModelProperty(value = "是否成功")
        private boolean success=true;
        @ApiModelProperty(value = "返回对象")
        private Object data;
        @ApiModelProperty(value = "错误编号")
        private Integer errCode;
        @ApiModelProperty(value = "错误信息")
        private String message;

        /* getter/setter */
    }

3、在Swagger可视化界面展示

输入 http://localhost:8080/user/getusers  结果如下:

{"uuid":"d882f714-c015-4c46-a92e-5d7e2a8b3380","name":"丫丫","age":12,"address":"浙江省","phone":"1898*****63","company":"alibaba"}

在浏览器打开:http://localhost:8080/swagger-ui.html
页面如下:

详细信息:

get请求

post请求

delete请求

4、详情测试

此时执行成功,已经达到所需的目标,End。
