Swagger2之springMVC的简单集成

搭建一个springMVC的demo工程

demo工程中pom.xml配置

              <!-- 接口文档和UI -->
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger2</artifactId>
			<version>2.4.0</version>
		</dependency>
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger-ui</artifactId>
			<version>2.4.0</version>
		</dependency>
                <!-- jackson必须加，否则swagger2异常  -->
                <dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-core</artifactId>
			<version>2.8.0</version>
		</dependency>
		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-databind</artifactId>
			<version>2.6.3</version>
		</dependency>
		<dependency>
		<groupId>com.fasterxml.jackson.core</groupId>
		<artifactId>jackson-annotations</artifactId>
		<version>2.6.3</version>
		</dependency>

swagger2需要定义启动配置类SwaggerConfig.java

package com.ppfuns.aaa.common;

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 org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
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;

/**
 * Created with IntelliJ IDEA.
 * User: xxx
 * Date: 2019/1/16
 * Time: 10:31
 * To change this template use File | Settings | File Templates.
 */
@Configuration  //启动配置
@EnableSwagger2      //启动swagger
@ComponentScan(basePackages = {"com.ppfuns.aaa.action"})  //扫描Action层接口列表目录
@EnableWebMvc
public class SwaggerConfig extends WebMvcConfigurationSupport {
    @Bean
    public Docket customDocket() {
        //
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        Contact contact = new Contact("22", "https://www.ppfuns.com", "[email protected]");
        return new ApiInfo("AAA 22",//大标题 title
                "Swagger 22 demo",//小标题
                "0.0.1",//版本
                "www.baidu.com",//termsOfServiceUrl
                 contact,//作者
                "22",//链接显示文字
                "https://www.ppfuns1.com"//网站链接
        );
    }
}

配置spring的xml配置，demo工程以springMvc为例，UI文件放在WEB-INF/swagger目录下

<!--  swagger静态文件路径 -->
	<mvc:resources mapping="/swagger/**" location="/WEB-INF/swagger/" cache-period="31556926"/>
	<mvc:default-servlet-handler />
	<bean class="com.ppfuns.aaa.common.SwaggerConfig" />

下载swagger-ui代码，引入dist目录下文件到WEB-INF/swagger/目录下；路径：https://github.com/swagger-api/swagger-ui

修改其中的目录WEB-INF/swagger/index.html文件

<!-- HTML for static distribution bundle build -->
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <title>Swagger UI</title>
    <link rel="stylesheet" type="text/css" href="../../resources/swagger/swagger-ui.css" >
    <link rel="icon" type="image/png" href="../../resources/swagger/favicon-32x32.png" sizes="32x32" />
    <link rel="icon" type="image/png" href="../../resources/swagger/favicon-16x16.png" sizes="16x16" />
    <style>
      html
      {
        box-sizing: border-box;
        overflow: -moz-scrollbars-vertical;
        overflow-y: scroll;
      }

      *,
      *:before,
      *:after
      {
        box-sizing: inherit;
      }

      body
      {
        margin:0;
        background: #fafafa;
      }
    </style>
  </head>

  <body>
    <div id="swagger-ui"></div>

    <script src="/resources/swagger/swagger-ui-bundle.js"> </script>
    <script src="/resources/swagger/swagger-ui-standalone-preset.js"> </script>
    <script>
    window.onload = function() {
      // Begin Swagger UI call region
      const ui = SwaggerUIBundle({
//        url: "https://petstore.swagger.io/v2/swagger.json",
     //url配置为：http://IP:PORT/{工程名}/v2/api-docs.json
        url:"http://localhost:8080/v2/api-docs.json",
        dom_id: '#swagger-ui',
        deepLinking: true,
        presets: [
          SwaggerUIBundle.presets.apis,
          SwaggerUIStandalonePreset
        ],
        plugins: [
          SwaggerUIBundle.plugins.DownloadUrl
        ],
        layout: "StandaloneLayout"
      })
      // End Swagger UI call region

      window.ui = ui
    }
  </script>
  </body>
</html>

启动应用，访问http://localhost:8080/swagger/index.html，如下图

以上swagger2和springMVC已集成在一起了，接下来对接口描述进行配置

@Api(description = "日志")
@Controller
@RequestMapping("/log")
public class LogController {
 
	@Autowired
	private ILogDAO mapper;
 
	@ApiOperation(value = "查询记录(GET)", notes = "查询记录:http method is get", httpMethod = "GET", produces = MediaType.APPLICATION_JSON_VALUE)
	@RequestMapping(value = "/user/queryByGet.json",method = RequestMethod.GET)
	@ResponseBody
	public APIResponse<List<Log>> queryByGet(
			@ApiParam(required = true, hidden = false, value = "用户名") @PathVariable String name,
			@ApiParam(required = true, hidden = false, value = "删除标识",example = "true",allowableValues = "true|false") @PathVariable boolean flag,
			@ApiParam(required = true, value = "当前页",allowableValues = "1,100",example = "5") @RequestParam("currentPage") int currentPage,
			@ApiParam(required = true, value = "每页显示数量") @RequestParam("pageSize") int pageSize) {
		Page page = new Page();
		page.setLow((currentPage - 1) * pageSize);
		page.setHight(currentPage * pageSize);
		page.setUsername(name);
		List<Log> logs = mapper.selectUserLogByPage(page);
 
		return APIResponse.returnSuccess(logs);
	}
 
	@ApiOperation(value = "查询记录(POST)", notes = "查询记录:http method is post", httpMethod = "POST", produces = MediaType.APPLICATION_JSON_VALUE)
	@RequestMapping(value = "/user/queryByPost.json",method = RequestMethod.POST)
	@ResponseBody
	public APIResponse<List<Log>> queryByPost(
			@ApiParam(required = true, hidden = false, value = "用户名") @PathVariable String name,
			@ApiParam(required = true, hidden = false, value = "删除标识",example = "true",allowableValues = "true|false") @PathVariable boolean flag,
			@ApiParam(required = true, value = "当前页",allowableValues = "1,5",example = "5") @RequestParam("currentPage") int currentPage,
			@ApiParam(required = true, value = "每页显示数量") @RequestParam("pageSize") int pageSize) {
		Page page = new Page();
		page.setLow((currentPage - 1) * pageSize);
		page.setHight(currentPage * pageSize);
		page.setUsername(name);
		List<Log> logs = mapper.selectUserLogByPage(page);
 
		return APIResponse.returnSuccess(logs);
	}
}
