springboot + swagger2 生成api文档

直接贴代码：

			<artifactId>springfox-swagger2</artifactId>
			<version>2.8.0</version>

　　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;

//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())

	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
