一、pom.xml引入基於maven的swagger依賴

　　　　　<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>

        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.9.7</version>
        </dependency>

二、編寫SwaggerConfig配置類

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@Configuration
@EnableSwagger2
@EnableWebMvc
@ComponentScan(basePackages 
 
= {"com.foriseland.fsoa.pay.controller"})
public class SwaggerConfig {
     @Bean
        public Docket customDocket() {
            return new Docket(DocumentationType.SWAGGER_2)
                    .apiInfo(apiInfo())      
                    .select()
                    .apis(RequestHandlerSelectors.any())
                    .paths(PathSelectors.any())
                    .build();
        }
 
        private ApiInfo apiInfo() {
            Contact contact = new Contact("支付組", "", "");
            return new ApiInfoBuilder()
                    .title("支付API介面")
                    .description("支付API介面")
                    .contact(contact)
                    .version("1.1.0")
                    .build();
        }
}

三、在spring mvc配置xml裡面加入Swagger配置

　　<!-- swagger -->
   <bean class="com.foriseland.fsoa.pay.swagger.SwaggerConfig"></bean>
   <mvc:default-servlet-handler/>
   <mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/>
   <mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>

四、controller層的編寫例子

@Controller
@CrossOrigin
@Api(tags="賬戶資訊控制類")
@RequestMapping("account")
public class AccountController{

    @ApiOperation(value = "獲取盈豆數量", notes = "獲取盈豆數量", httpMethod = "POST")
    @RequestMapping(value="getBeansNumber", method=RequestMethod.POST)
    @ResponseBody
    public void getBeansNumber(@RequestBody BeansCountDto info, HttpServletResponse response) {
 
    }
}

五、啟動專案

http://127.0.0.1:8080/{projectName}/swagger-ui.html
