spring-boot整合swagger生成在线api文档

最近用springboot构建rest接口，考虑到最方便的验证接口，想到了引入swagger。

基本的步骤大致如下：

1.pom中引入swagger依赖：

<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
</dependency>

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

2.创建swagger的配置类：

package com.coder520.mamabike.common.swagger;

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 SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.coder520.mamabike"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("码码共享单车API文档")
                .version("1.0")
                .build();
    }

}

然后在controller层的方法中添加注解
比如这样：

    @ApiOperation(value="短信验证码",notes = "根据用户手机号码发送验证码",httpMethod = "POST")
    @ApiImplicitParam(name = "user",value = "用户信息 包含手机号码",required = true,dataType = "User")
    @RequestMapping("/sendVercode")
    public ApiResult sendVercode(@RequestBody User user,HttpServletRequest request){
        ApiResult<String> resp = new ApiResult<>();

        try {
            if(StringUtils.isEmpty(user.getMobile())){
                throw new MaMaBikeException("手机号码不能为空");
            }
            userService.sendVercode(user.getMobile(),getIpFromRequest(request));
            resp.setMessage("发送成功");
        } catch (MaMaBikeException e) {
            resp.setCode(e.getStatusCode());
            resp.setMessage(e.getMessage());
        } catch (Exception e) {
            log.error("Fail to update user info", e);
            resp.setCode(Constants.RESP_STATUS_INTERNAL_ERROR);
            resp.setMessage("内部错误");
        }

        return resp;
    }

然后访问http://localhost:8080/swagger-ui.html这个路径。

中间可能会出现json的错误，就是你项目中采用的是fastjson，出现错误提示

fetching resource list: http://localhost:8080/v2/api-docs; Please wait.

解决方法自行百度把。
