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:

  • 服务器端和android客户端提供最佳性能
  • 提供简单toJSONString()和parseObject()方法的Java对象转换为JSON,反之亦然
  • 允许存在的无法改变的对象转换为从JSON
  • Java泛型的广泛支持
  • 允许自定义表示对象
  • 支持任意复杂的对象(深继承层次结构和广泛使用泛型类型)

主要特点:

  • 快速FAST (比其它任何基于Java的解析器和生成器更快,包括jackson)
  • 强大(支持普通JDK类包括任意Java Bean Class、Collection、Map、Date或enum)
  • 零依赖(没有依赖其它任何类库除了JDK)
  • 支持注解

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 parseObject(String text, Class 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  List parseArray(String text, Class 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

JSONObject:相当于Map

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 :

  • QuoteFieldNames 输出key时是否使用双引号,默认为true
  • UseSingleQuotes 使用单引号而不是双引号,默认为false
  • WriteMapNullValue 是否输出值为null的字段,默认为false
  • WriteEnumUsingToString Enum输出name()或者original,默认为false
  • UseISO8601DateFormat Date使用ISO8601格式输出,默认为false
  • WriteNullListAsEmpty List字段如果为null,输出为[],而非null
  • WriteNullStringAsEmpty 字符类型字段如果为null,输出为”“,而非null
  • WriteNullNumberAsZero 数值字段如果为null,输出为0,而非null
  • WriteNullBooleanAsFalse Boolean字段如果为null,输出为false,而非null
  • SkipTransientField 如果是true,类中的Get方法对应的Field是transient,序列化时将会被忽略。默认为true
  • SortField 按字段名称排序后输出。默认为false
  • WriteTabAsSpecial 把\t做转义输出,默认为false 不推荐
  • PrettyFormat 结果是否格式化,默认为false
  • WriteClassName 序列化时写入类型信息,默认为false。反序列化是需用到
  • DisableCircularReferenceDetect 消除对同一对象循环引用的问题,默认为false
  • WriteSlashAsSpecial 对斜杠'/'进行转义
  • BrowserCompatible 将中文都会序列化为\uXXXX格式,字节数会多一些,但是能兼容IE 6,默认为false
  • WriteDateUseDateFormat 全局修改日期格式,默认为false。JSON.DEFFAULT_DATE_FORMAT = “yyyy-MM-dd”;JSON.toJSONString(obj, SerializerFeature.WriteDateUseDateFormat);
  • DisableCheckSpecialChar 一个对象的字符串属性中如果有特殊字符如双引号,将会在转成json时带有反斜杠转移符。如果不需要转义,可以使用这个属性。默认为false
  • NotWriteRootClassName 含义
  • BeanToArray 将对象转为array输出
  • WriteNonStringKeyAsString
  • NotWriteDefaultValue
  • BrowserSecure
  • IgnoreNonFieldGetter
  • WriteEnumUsingName

}

Swagger集成

第一步:引入相关依赖


 io.springfox
 springfox-swagger2
 2.6.1
 compile


 com.fasterxml.jackson.core
 jackson-databind
 2.6.6

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:

  • @Api(description = “接口类的描述”)
  • @ApiOperation(value = “接口方法的名称”, notes = “备注说明”)
  • @ApiParam(name = “参数名称”, value = “备注说明”, required = 是否必须):标注在方法的参数上 用于描述参数的名称、备注、是否必须等信息
  • @ApiImplicitParam(paramType = “query”, name = “password”, dataType = “String”, required = true, value = “密码”, defaultValue = “123456”)用于描述方法的参数,标注在方法上,和@ApiParam功能一样,只是标注的位置不同而已
         .paramType:参数类型,即参数放在哪个地方
                .   header–>请求参数的获取:@RequestHeader,参数放在请求头
                 .   query–>请求参数的获取:@RequestParam,参数追加在url后面
                 .   path(用于restful接口)–>请求参数的获取:@PathVariable
                 .   body 使用@RequestBody接收数据 POST有效,参数放在请求体中
                 .    form
        .name:参数名
        .dataType:参数的数据类型
        .required:参数是否必须传
        .value:参数的描述
        .defaultValue:参数的默认值
  • @ApiImplicitParams: 用于包含多个@ApiImplicitParam
  • @ApiResponse(code = 0, message = “success”),
         .code:响应码,例如400
         .message:信息,一般是对code的描述
         .response:抛出异常的类
  • @ApiModel:描述一个Model的信息(这种一般用在post创建的时候,使用@RequestBody这样的场景,请求参数无法使用@ApiImplicitParam注解进行描述的时候)
         .@ApiModelProperty:描述一个model的属性
                  .   position 允许在模型中显式地排序属性。
                  .   value 参数名称
                  .   required 是否必须 boolean
                  .   hidden 是否隐藏 boolean
                  .   allowableValues = “range[0, 1]” 一般用于指定参数的合法值
  • @ApiIgnore:用于或略该接口,不生成该接口的文档

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

Spring MVC+FastJson+Swagger集成的完整实例教程

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

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


2、 在web.xml中增加要过滤的静态文件



 default
 *.js
 *.css
 /assets/*"
 /images/*

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


 spring-mvc
 org.springframework.web.servlet.DispatcherServlet
  
 contextConfigLocation 
 /WEB-INF/spring-servlet.xml 
 
 1

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

  • org.springframework.web.servlet.view.UrlBasedViewResolver
  • tiles3: org.springframework.web.servlet.view.tiles3.TilesConfigurer
  • springMVC: org.springframework.web.servlet.view.InternalResourceViewResolver,
  • shiro: org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor
  • 上传 org.springframework.web.multipart.commons.CommonsMultipartResolver,

静态资源映射





 

org.springframework.context.support.ResourceBundleMessageSource

返回结果的解析

  • FastJson: com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter

3、applicationContext.xml 是系统级别的配置,作用范围是系统上下文,它的初始化需要放到 web.xml 中的context-param中配置


 contextConfigLocation
 classpath:conf/spring/spring-*.xml

4、 关于applicationContxt.xml,一般是按照功能拆成多个配置文件如:

  • - applicationContxt-base.xml // 基础
  • - applicationContxt-redis.xml // redis相关配置
  • - applicationContxt-shiro.xml // shiro 相关配置
  • - applicationContxt-dao.xml // 数据库相关配置
  • - applicationContxt-xxx.xml // xxx
