springboot + swagger2 生成api文档

直接贴代码：

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.8.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.8.0</version>
        </dependency>

　　config

import io.swagger.annotations.ApiOperation;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
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;
 
 
//ConditionalOnProperty 注解，是为了根据配置文件的配置来指定swagger，是否生效。如果需要生效，就在application文件中配置 swagger.enable=true
@ConditionalOnProperty(prefix = "swagger",value = {"enable"},havingValue = "true")
@Configuration
@EnableSwagger2
public class SwaggerConfig extends WebMvcConfigurerAdapter {
 
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars*")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
 
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .forCodeGeneration(true)
                .useDefaultResponseMessages(false)
                .apiInfo(apiInfo())
                .select()
//              .apis(RequestHandlerSelectors.basePackage(""))
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build();
    }
 
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(" API文档")
                .description(" API文档")
                .version("1.0")
                .build();
    }
}

　　返回model

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
 
/**
 * 封装返回数据javabean
 *
 **/
@ApiModel(value = "Result",description = "通用返回对象")
public class Result {
    public final static String MSG_SUCCESS = "success";
 
    @ApiModelProperty(value = "调用是否正常",name = "isok")
    private boolean isok;
    @ApiModelProperty(value = "接口返回msg，如果isok是false，那么msg是错误信息",name = "msg")
    private String msg;
    @ApiModelProperty(value = "调用成功，返回的数据",name = "data")
    private Object data;
 
    public Result() {
    }
 
    public Result(boolean isok, String msg) {
        this.isok = isok;
        this.msg = msg;
    }
 
    public Result(boolean isok, String msg, Object data) {
        this.isok = isok;
        this.msg = msg;
        this.data = data;
    }
 
    public boolean isIsok() {
        return isok;
    }
 
    public void setIsok(boolean isok) {
        this.isok = isok;
    }
 
    public String getMsg() {
        return msg;
    }
 
    public void setMsg(String msg) {
        this.msg = msg;
    }
 
    public Object getData() {
        return data;
    }
 
    public void setData(Object data) {
        this.data = data;
    }
}

　　controller 上注解：

@Api(value = "/XXX",tags = "查询接口")

method 上注解示例：

@ApiOperation(value = "XXX",notes = "XXXX")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "methodName",value = "XXX",required = true,dataType = "String",paramType = "query"),
            @ApiImplicitParam(name = "params",value = "XXXXX",required = true,paramType = "body")
    })

public Result selectServiceRun(String methodName,
                        @RequestBody Map<String, Object> params,
                        HttpServletRequest request) {

说明：

@Api：用在类上，说明该类的作用
@ApiOperation：用在方法上，说明方法的作用
@ApiImplicitParams：用在方法上包含一组参数说明
@ApiImplicitParam：用在@ApiImplicitParams注解中，指定一个请求参数的各个方面
- 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）
- name：参数名
- dataType：参数类型
- required：参数是否必须传
- value：参数的意思
- defaultValue：参数的默认值
@ApiResponses：用于表示一组响应
@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
@ApiModel：描述一个Model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：描述一个model的属性
