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
特性:
- 在服务器端和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> 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 :
- 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
实战部分
1、pom.xml 中引入spring mvc、 fastjson 依赖

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

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
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 ),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

2
|
<!-- 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> |

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
- 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

<mvc:resources location= "/static/" mapping= "/static/**" /> <mvc:resources location= "/images/" mapping= "/static/**" /> <mvc:resources location= "/css/" mapping= "/static/**" /> <mvc:resources location= "/js/" mapping= "/static/**" /> <mvc:resources location= "/html/" mapping= "/static/**" /> <mvc:resources location= "/upload/" mapping= "/static/**" /> |
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
1

|
<context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:conf/spring/spring-*.xml</param-value> </context-param> |
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
