Spingboot 整合swagger2

1.pom.xml

添加

        <!--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.Swagger2Configuration.java

package com.soft.xx.config;

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;

/**
 * Swagger2配置类
 * 通过@Configuration注解，让Spring来加载该类配置。
 * 再通过@EnableSwagger2注解来启用Swagger2。
 */
@Configuration
@EnableSwagger2
public class Swagger2Configuration {

    /**
     * 创建API应用
     * apiInfo() 增加API相关信息
     * 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指定要建立API的目录。
     *
     * @return
     */
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.soft.xx"))
                .paths(PathSelectors.any())
                .build();
    }

    /**
     * 创建该API的基本信息（这些基本信息会展现在文档页面中）
     * 访问地址：http://项目实际地址/swagger-ui.html
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("swagger2测试")
                .description("")
                .termsOfServiceUrl("")
                .contact("suphowe")
                .version("1.0")
                .build();
    }
}

3.修改controller

import com.alibaba.dubbo.config.annotation.Reference;
import com.soft.api.service.IProviderDemo;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

@RestController
@CrossOrigin
@Api(value = "swagger2测试")
public class ConsumerController {

    @Reference
    private IProviderDemo providerDemo;

    @ResponseBody
    @RequestMapping(value = "/callInterfase", produces = "text/plain;charset=UTF-8", method = RequestMethod.POST)
    @ApiOperation(value = "消费者接口调用", notes = "消费者接口调用")
    @ApiImplicitParams({
            @ApiImplicitParam(paramType = "query", name = "info", value = "info", required = false, dataType = "String")
    })
    public String callInterfase(String info) {
        String hello = providerDemo.providerReturnString("consumer test " + info);
        System.out.println(providerDemo.providerReturnString("consumer print " + info));
        return hello;
    }
}

4.访问url :http://127.0.0.1:9021/swagger-ui.html

 

 

5.测试接口

 

 6.遇到的坑

***************************

Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed


Process finished with exit code 1

　　问题处理：开始使用的是swagger为2.2.2版本,springboot为2.3.0版本，报如上错误

　　　　　　将swagger版本升级为2.9.2，Reimport，重启正常
