JavaWeb项目中集成Swagger API文档

1.增加依赖

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.7.0</version>
        </dependency>

2.配置类SwaggerConfig.java

package com.example.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
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
@ComponentScan(basePackages = { "com.example.demo" })
public class SwaggerConfig {
    ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("demo Web service APIs")
                .description("")
                .license("")
                .licenseUrl("")
                .termsOfServiceUrl("")
                .version("1.0.0")
                .build();
    }

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo"))
                .build()
                .apiInfo(apiInfo());
    }

}

3.启动类加 @EnableSwagger2 注解

package com.example;

import com.example.config.SupplyConfig;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@EnableConfigurationProperties(SupplyConfig.class)
@EnableSwagger2
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

4.接口类加@Api及接口方法加@ApiOperation注解

package com.example.demo.controller;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/greet")
@Api(value = "demo api")
public class HelloWorldController{

    @ApiOperation(value = "问好")
    @RequestMapping(value = "helloworld",method = RequestMethod.GET)
    public String sayHello() {
        return "hello world cc";
    }
}

5.访问swagger-ui

http://localhost:8080/swagger-ui.html （端口是spring-boot项目启动的端口），打开页面如下：

发送get请求：
