Spring MVC+FastJson+Swagger集成的完整实例教程

作者:vbirdbest

这篇文章主要给大家分享介绍了关于Spring MVC+FastJson+Swagger集成的完整实例教程,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧。

基础部分

1. FastJson 简介

Fastjson是一个Java库,可用于将Java对象转换为JSON表示。它也可以被用来将一个JSON字符串转换成一个等效的Java对象。在转换速度上应该是最快的,几乎成为了项目的标配(在ajax请求和接口开发时一般都会用fastjson而不再使用jackson)。

GitHub: https://github.com/alibaba/fastjson (本地下载

特性:

主要特点:

2. fastjson api

Fastjson API入口类是com.alibaba.fastjson.JSON,常用的序列化操作都可以在JSON类上的静态方法直接完成。

// 把JSON文本parse为JSONObject或者JSONArray 
public static final Object parse(String text); 

// 把JSON文本parse成JSONObject 
public static final JSONObject parseObject(String text); 

// 把JSON文本parse为JavaBean 
public static final <T> T parseObject(String text, Class<T> clazz); 

// 把JSON文本parse成JSONArray 
public static final JSONArray parseArray(String text); 

// 把JSON文本parse成JavaBean集合 
public static final <T> List<T> parseArray(String text, Class<T> clazz); 

// 将JavaBean序列化为JSON文本 
public static final String toJSONString(Object object); 

// 将JavaBean序列化为带格式的JSON文本 
public static final String toJSONString(Object object, boolean prettyFormat); 

// 将JavaBean转换为JSONObject或者JSONArray
public static final Object toJSON(Object javaObject); 

JSONArray:相当于List<Object>

JSONObject:相当于Map<String, Object>

SerializeConfig: 是对序列化过程中一些序列化过程的特殊配置, 如对一些字段进行格式处理(日期、枚举等)

SerializeWriter:相当于StringBuffer

SerializerFeature属性 :

实战部分

1、pom.xml 中引入spring mvc、 fastjson 依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、 配置web.xml

<!DOCTYPE web-app PUBLIC

3、 配置spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

Swagger集成

第一步:引入相关依赖

<dependency>
 <groupId>io.springfox</groupId>
 <artifactId>springfox-swagger2</artifactId>
 <version>2.6.1</version>
 <scope>compile</scope>
</dependency>
<dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-databind</artifactId>
 <version>2.6.6</version>
</dependency>

第二步:Swagger信息配置

SwaggerConfig.java

@Configuration
@EnableWebMvc
@EnableSwagger2
public class SwaggerConfig {
 @Bean
 public Docket customDocket() {
 Docket docket = new Docket(DocumentationType.SWAGGER_2);
 docket.apiInfo(apiInfo());
 docket.select().apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class));
 docket.select().paths(PathSelectors.regex("/api/.*")).build();

 return docket;
 }

 private ApiInfo apiInfo() {
 Contact contact = new Contact("小明", "http://www.baidu.com", "baidu@163.com");
 return new ApiInfo("API接口", //大标题 title
 "API接口", //小标题
 "0.0.1", //版本
 "www.baidu.com",//termsOfServiceUrl
 contact,//作者
 "API接口",//链接显示文字
 "http://www.baidu.com"//网站链接
 );
 }
}

注意:因SwaggerConfig这个类配置了注解,所以这个类必须被扫描到,即该类一定包含在context:component-scan中。

第三步:在类、方法、参数上使用注解

@Controller
@RequestMapping("/api/v1")
@Api(description = "API接口")
public class ApiController {
 @ApiOperation(value = "用户登录", notes = "用户登录接口")
 @ApiResponses({
 @ApiResponse(code = 0, message = "success"),
 @ApiResponse(code = 10001, message = "用户名错误", response = IllegalArgumentException.class),
 @ApiResponse(code = 10002, message = "密码错误")
 })
 @RequestMapping(value = "/user/login", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8;"})
 @ResponseBody
 public String login(@ApiParam(name = "username", value = "用户名", required = true) @RequestParam String username,
  @ApiParam(name = "password", value = "密码", required = true) @RequestParam String password){
 return "{'username':'" + username + "', 'password':'" + password + "'}";
 }


 @ApiImplicitParams({
 @ApiImplicitParam(paramType = "header", name = "phone", dataType = "String", required = true, value = "手机号"),
 @ApiImplicitParam(paramType = "query", name = "nickname", dataType = "String", required = true, value = "nickname", defaultValue = "双击666"),
 @ApiImplicitParam(paramType = "path", name = "platform", dataType = "String", required = true, value = "平台", defaultValue = "PC"),
 @ApiImplicitParam(paramType = "body", name = "password", dataType = "String", required = true, value = "密码")
 })
 @RequestMapping(value = "/{platform}/user/regist", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8;"})
 @ResponseBody
 public String regist(@RequestHeader String phone, @RequestParam String nickname, @PathVariable String platform, @RequestBody String password){
 return "{'username':'" + phone + "', 'nickname':'" + nickname + "', 'platform': '" + platform + "', 'password':'"+password+"'}";
 }

 @RequestMapping(value = "/user/list", method = RequestMethod.GET, produces = {"application/json;charset=UTF-8;"})
 @ResponseBody
 public String getUserList(Pager pager){
 return "[{'id': "+pager.getPage()+", 'username': 'zhangsan"+pager.getSize()+"'}]";
 }

 @RequestMapping("/docs")
 @ApiIgnore
 public String test(){
 return "api-docs";
 }
}

Pager

public class Pager {
 @ApiModelProperty(value = "页码", required = true)
 private int page;
 @ApiModelProperty(value = "每页条数", required = true)
 private int size;

 public Pager() {
 }

 public int getPage() {
 return page;
 }

 public void setPage(int page) {
 this.page = page;
 }

 public int getSize() {
 return size;
 }

 public void setSize(int size) {
 this.size = size;
 }
}

常用注解:

第四步:访问/v2/api-docs

在浏览器上访问http://localhost:8080/工程名称/v2/api-docs 如果有json内容,证明正常

第五步:下载swagger-ui

从github上下载https://github.com/swagger-api/swagger-ui,注意这里要选择下载v2.2.10(https://github.com/swagger-api/swagger-ui/tree/v2.2.10 (本地下载)),大于这个版本的集成方式不一样。

集成方法:将v2.2.10下的dist目录下的所有文件放到自己工程中静态文件中,并使用下面代码覆盖掉index.html中的脚本部分

<script type="text/javascript">
 var baseUrl = "";
 $(function () {
  var url = window.location.search.match(/url=([^&]+)/);
  if (url && url.length > 1) {
  url = decodeURIComponent(url[1]);
  } else {
  //上面描述的api-docs地址
  url = baseUrl + "/webapp/v2/api-docs";
  }

  // Pre load translate...
  if (window.SwaggerTranslator) {
  window.SwaggerTranslator.translate();
  }
  window.swaggerUi = new SwaggerUi({
  url: url,
  validatorUrl: undefined,
  dom_id: "swagger-ui-container",
  supportedSubmitMethods: ['get', 'post', 'put', 'delete', 'patch'],
  onComplete: function (swaggerApi, swaggerUi) {

   if (typeof initOAuth == "function") {
   initOAuth({
    clientId: "your-client-id",
    clientSecret: "your-client-secret-if-required",
    realm: "your-realms",
    appName: "your-app-name",
    scopeSeparator: ",",
    additionalQueryStringParams: {}
   });
   }

   if (window.SwaggerTranslator) {
   window.SwaggerTranslator.translate();
   }

   $('pre code').each(function (i, e) {
   hljs.highlightBlock(e)
   });

   addApiKeyAuthorization();
  },
  onFailure: function (data) {
   log("Unable to Load SwaggerUI");
  },
  docExpansion: "none",
  jsonEditor: false,
  apisSorter: "alpha",
  defaultModelRendering: 'schema',
  showRequestHeaders: false
  });

  //这里可以添加权限认证,例如token
  function addApiKeyAuthorization() {
  var token = "you-token";
  var tokenHeader = new SwaggerClient.ApiKeyAuthorization("token", token, "header");
  window.swaggerUi.api.clientAuthorizations.add("token", tokenHeader);
  }

  window.swaggerUi.load();
  function log() {
  if ('console' in window) {
   console.log.apply(console, arguments);
  }
  }
 });
 </script>

第六步:访问上面修改的那个index.html
http://localhost:8080/工程名称/static/third-party/swagger-ui/index.html

注意:因要访问静态资源,使用springmvc请确保静态资源能够被访问到,如果不能访问请做如下配置:

1、 在Spring的配置文件中增加默认的servlet处理器

<!-- 过滤静态资源 -->
<mvc:default-servlet-handler/>

2、 在web.xml中增加要过滤的静态文件

<!-- 过滤静态资源 -->
<servlet-mapping>
 <servlet-name>default</servlet-name>
 <url-pattern>*.js</url-pattern>
 <url-pattern>*.css</url-pattern>
 <url-pattern>/assets/*"</url-pattern>
 <url-pattern>/images/*</url-pattern>
</servlet-mapping>

示例项目代码结构:

完整示例Demo下载地址: http://xiazai.jb51.net/201804/yuanma/platform-springmvc-webapp(jb51.net).rar

其他

关于spring-servlet.xml 和 applicationContext.xml

SpringMVC 提供了两种配置文件 spring-servlet.xml 、 applicationContext.xml
spring-servlet.xml 是Controller级别的,作用范围是控制层,默认的名字是【servlet-name】-servlet.xml
默认是放在WEB-INF/目录下,SpringMVC会自动加载,也可以在web.xml中配置它的位置

<servlet>
 <servlet-name>spring-mvc</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <init-param> 
 <param-name>contextConfigLocation</param-name> 
 <param-value>/WEB-INF/spring-servlet.xml</param-value> 
 </init-param>
 <load-on-startup>1</load-on-startup>
</servlet>

一般在spring-servlet.xml中配置一些和控制器相关的配置,如视图解析、静态资源文件的映射、返回结果的解析等

视图解析

静态资源映射

<mvc:resources location="/static/" mapping="/static/**" />
