一、添加Swagger2依赖

    <properties>
        <springfox.version>2.7.0</springfox.version>
    </properties>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>${springfox.version}</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>${springfox.version}</version>
        </dependency>

二、编写Swagger2配置类

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;

/**
 * Created by flysheep on 2017/9/30.
 */
@Configuration
@EnableSwagger2
public class Swagger2Configuration {

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

    private ApiInfo buildApiInf() {
        return new ApiInfoBuilder()
                .title("security-login-check 接口文档")
                .description("security-login-check 提供的接口描述文档")
                .build();

    }

}

三、编写Controller

import com.domain.base.ResultDTO;
import com.domain.request.PasswordErrorFrequencyRequest;
import com.util.ResultDTOUtil;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by flysheep on 2017/9/30.
 */
@Api(value = "安全登录校验controller", description = "密码错误次数校验", tags = {"安全登录校验接口"})
@RestController
public class SecurityLoginCheckController {

    @ApiOperation("密码错误次数校验")
    @PostMapping("/checkPassword")
    public ResultDTO checkPasswordErrorFrequency(PasswordErrorFrequencyRequest request) {
        // TODO: 2017/9/30 具体的业务逻辑
        return ResultDTOUtil.successResult(null);
    }

}

完成上述代码后，打包Spring Boot程序并启动，打开浏览器访问：http://localhost:8080/swagger-ui.html，就能看到展示的RESTful API的页面。
