    一、背景介绍

                 为了加快Tomcat环境下基于Axis2引擎的WebService开辟,将开辟Web Service的处置如参数解析,方法调用和结果返回进行了封装,生成一个Axis2Service.jar包,实现了Web Service的输入,处置和输出的可配置,简化了WebService的开辟工作,并应用Axis2hotupdatehotdeploy功能,直接从WebServicepropertiesXML配置文件生成WebService代码,主动编译成class发布,简化了WebService的开辟,并可部署相应的URL转换Servlet,缩短了WebService的调用URL

        

    二、主动创立流程

        

    1. Web Service Request

            用户或系统Server发出Web Service Request请求,包括Request URL以及相应的参数

        例如http://10.139.8.167:8080/TestService/beeCommission?

        strXMLParameter=<?xml version='1.0' encoding= 'UTF-8'?><requestversion='1.0'><beeCommissionCommand><Parameters><sessionID>112843584</sessionID><startDate>20130101</startDate><endDate></endDate></Parameters></beeCommissionCommand></request>  

        这是XML格式的RequestParameter;

        http://10.139.8.167:8080/TestService/javaMethod?userId=leoliao&orderTime=20130326111259

        这是String格式的RequestParameter

        

    2. Web Service名称取得

            从服务器上响应上述URLServlet收到的的Request URI中取得Web Service的名称。例如上述Web Service Request中,取得Service Name为:TestService

        

    3. Web Service代码生成

         Web Service的配置文件分为两种:

        一种是XML文件,是全配置的Web Service,输入,执行操作和输出都可配置;

        另一种是properties文件,是简单配置Web Service,直接将Web Service Mapping到指定的java方法。

            根据Tomcat路径下conf目录中WSConfigure活页夹中所有的web serviceconfigure XML文件及properties文件,依次加载每一个XML文件到WebService对象,加载每一个properties文件到SimpleWebService对象,并生成相应的public java 方法,加上importAxis2Service jar包中的语句,组成Web Servicejava文件,放在Axis2缺省发布class文件作为web service的目录下。

            每个Web Service配置文件都市有Debug的开关,如果所有的Web Service的配置文件中的Debug都是关闭的,则Web Service的主动生成和编译就不会运行。(Web Service Debug实现,正式发布后,应该把所有配置文件中的Debug都关掉。)

        例如,上述例子中,读取Web Service XMLconfigure文件的路径为:E:\java\Tomcat7022\conf\WSConfigure

        生成的Web Service代码文件为TestService.java,存放路径为:

        E:\java\Tomcat7022\webapps\axis2\WEB-INF\pojo

         

        

    4. Web Service代码编译

        调用Java runtime,执行javac,编译生成的Web Service java代码,生成class文件,被主动发布为Web Servicejava代码里面的每一个大众方法,都将发布成一个Web Service方法。

        

    5. Web Service调用

           转换短的Web Service调用URL,并处置所有参数,生成新的Web Service URL然后把调用Redirect到新的Web Service URL,实现Web Service调用。

           例如:

        http://10.139.8.167:8080/TestService/javaMethod?userId=leoliao&orderTime=20130326111259

        将被转换为:

        http://10.139.8.167:8080/axis2/services/TestService/javaMethod?userId=leoliao&orderTime=20130326111259

        

    、开辟准备

        1. Install Tomcat

          Install JDK set System VariableJAVA_HOME

          Install Tomcat  apache-tomcat-7.0.22.exe (Tomcat7.exe)

        安装完毕后,在IE中输入http://localhost:8080应能看到如下Tomcat的启动界面

        如果没法看到此界面,说明Tomcat安装不胜利,请检查相干配置及安装文件并重新安装直至胜利。

                          方法和文件           

        2. Install Axis2

          Downloadaxis2-1.6.1-bin.zip,unzip,set System variable AXIS2_HOME

          Download axis2.war,copy toTomcat7 webapps

        Tomcat会主动解压axis2.war,在webapps目录中生成一个axis2的活页夹,所有axis2 Web Service引擎的应用文件都在这个目录下。

        Axis2安装完毕,在IE中输入http://localhost:8080/axis应能看到如下Axis2的主界面:

        方法和文件

        如果看不到这个界面,说明Axis2安装不胜利,请检查相干设置,确保Axis2安装胜利。

         

        3. Tomcat设定

          取得Axis2Service.jar包,放入tomcatlib目录中。

          tomcatconf目录下的web.xml,增加TestService(要开辟的WebService的名称)的servlet注册:

        <servlet>

            <servlet-name>TestService</servlet-name>

            <servlet-class>com.foxconn.cmmsg.itss.URLTransfer</servlet-class>

        </servlet>

        mapping到对所有以TestService开始的URL,也就是TestService所包含的所有API拜访路径,都市由这个Servlet来处置:

        <servlet-mapping>

                <servlet-name>TestService</servlet-name>

               <url-pattern>/TestService/*</url-pattern>

        </servlet-mapping>

        4. Axis2设定

          应用Axis2用最简单的缺省POJO方式发布Web Service,防止打包成aar文件再发布的繁琐步骤:

        直接把编译好的TestService.class文件放到axis2\WEB-INF\pojo目录中

        如果没有pojo目录,则建立该目录;

        如果须要应用其他目录名称,请修改axis2\WEB-INF\conf\axis2.xml中:

        <deployer extension=".class"directory="pojo"class="org.apache.axis2.deployment.POJODeployer"/>

        缺省的pojo为其他的目录名。

          修改axis2\WEB-INF\conf\axis2.xml中:

        <parametername="hotdeployment">true</parameter>

        启用热发布功能,Tomcat不须要重新启动就能够主动发布Web Service

          修改axis2\WEB-INF\conf\axis2.xml中:

        <parameter name="hotupdate">true </parameter>

        启用热更新功能,Tomcat不须要重新启动就能够更新已发布胜利的Web Service

        

    四、Web Service配置文件

        应用Axis2Servic.jar包所包含的框架进行Web Service的开辟,最重要的工作就是配置Web ServiceXMLproperties configure文件。这些configure文件缺省路径在Tomcatconf目录下的WSConfigure文件夹:

         方法和文件

        

    1.Simple Service Properties

        Web ServiceProperties configure配置文件比较简单:

        例如simpleService.properties内容如下:

        sevice.version =1.0  service版本

        service.ame=simpleService  service名称

        service.debug=true  是不是打开debug

        service.datasource=hiverService 数据源JNDI名称

        service.classfolder=WSClass  加载类文件的活页夹

        Mapping2JavaMethod=ServiceImpl.simpleService  service mapping到的java类和公然静态方法名称

        Parameters=para1,para2,para3  service的参数列表

        Web ServiceXMLconfigure配置文件重要分四部分,依次介绍如下:

        

    2. Service Header

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

        <service name="JavaMethod" tag="JavaMethod"version="1.0"

                 debug="true"datasource="hiver" classfolder="WSClass">

                 <errormessageList>

        <errormessage>Success.</errormessage>

                    <errormessage>Your accountis locked.</errormessage>

                    <errormessage>Fail to pairyour account.</errormessage>

                    <errormessage>API version isincorrect.</errormessage>

                 </errormessageList>

        这里定义了WebService方法的名称,表现的TagAPI版本,是不是打开debug,应用的数据源以及如果应用Java方法,引用的javaclass的活页夹。

        errormessageList部分可以有一条或多条,是针对此web service定义的error message,次序位置为对应的errorcode

        每个Web Service方法都必须有。

        

    3.RequestParameters

        <requestParameters format="String">

                           <requestParameter>

                                    <name>userId</name>

                                    <tag>userId</tag><!--tag-->

                                    <type>text</type><!--type-->

                                    <required>Yes</required><!--isRequired-->

                                    <mapping>_userid</mapping><!--mappingto field -->

                           </requestParameter>

                ….

        这里定义了Web Service方法RequestParameter的格式,可以有XMLJSONSTRING(通过URL QueryString)三种格式;随后是各个RequestParameter的具体定义,可以有0到多个RequestParameter

        RequestParameter定义中:

        nameparameter的名字,

        tagparameterXMLJSONURL中输入时的tag,平日和name保持一致,

        typeparameter的类型,可所以textnumericdoublefloatintegerintdigital

        requiredparameter是不是必须,如果为1,y,t,yestrue,则此parameter不准为空,

        mappingparameter作为下一步ServiceOperation输入参数时的参数名称。

        

    4. ServiceOperations

            <serviceOperations name="{call sp_checkSession(?,?,?) }"

                           format="sp">

                           <operationParameter>

                                    <name>_userid</name>

                                    <mode>IN</mode>

                                    <type>varchar</type>

                                    <preprocess>trim</preprocess>

                                    <mapping>userId</mapping>

                           </operationParameter>

        这里定义了Web Service方法要进行的ServiceOperation,格式可所以SPname就是调用SP的语句,包括sp名称;或者java,则name就是要执行的java方法的包名及类名;如果此java方法有参数,则name@@开头。

        上面ServiceOperations的各个operationParameter定义。可以有0到多个参数:

        nameparameter的名字,

        modeparameter的模式,INOUTINOUT

        typeparameter的类型,因为此类型可能要对应到数据库参数类型,所以有CHAR,VARCHAR,FLOAT,DOUBLE,INTEGER,BIGINT,JAVA方法,可以都填VARCHAR

        preprocessparameter的预处置,目前有以下几种:

        trim

        tolowercase

        touppercase

        md5

        sha1sha-1

        base64

        decodebase64 decode),

        uuid(随机UUID字符串,value为长度,如果value为空,缺省长度为16),

        hex(随机16进制字符串,value为长度,如果value为空,缺省长度为16),

        random(随机字符串,value为长度,如果value为空,缺省长度为16),

        ip

        format(?),其中?为一整数,对value取证到?位,

        hex(?),其中?为一整数,对value转换到16进制?位。

        mappingparameter mappingRequest Parameter的名字,此parameter会取相应的RequestParamter的值;

        如果mapping字符串包含.,则为mappingjava方法取值,如果mapping字符串中不包含(…),则为Java方法无参调用;否则,为有参java方法调用,mapping字符串中方法名后括号中的字符串为参数列表,多个参数以@@分隔,参数名 mappingRequestParamter取值。

        

    5.ResponseOutput

        <responseOutput format="xml">

                 <outputParameter>

        每日一道理
    美丽是平凡的,平凡得让你感觉不到她的存在;美丽是平淡的,平淡得只剩下温馨的回忆;美丽又是平静的,平静得只有你费尽心思才能激起她的涟漪。

                           <name>Success</name>

                           <tag>Success</tag>

                           <mapping>NULL</mapping>

                 </outputParameter>

        这里定义的是Web Service方法返回的格式,有XMLJSONSTRING,以及参数,可以有1到多个参数,其中参数nameerrorcode的若值为0,表示胜利,其余值表示失败:

        Outputparameter定义中:

        name parameter名,

        tagparameter表现在XMLJSONString中的tag,平日和name保持一致,多级tag旁边加.,例如<output><time>这类tag,应设定为output.time,

        mappingparametermappingServiceParameterRequestParameter的名字,

        如果mapping字符串为不含.则为参数取值,NULL表示空值,其余表示mappingService ParameterRequest Parameter取值;

        mapping字符串包含.,则为mappingjava方法取值,如果mapping字符串中不包含(…),则为Java方法无参调用;否则,为有参java方法调用,mapping字符串中方法名后括号中的字符串为参数列表,多个参数以@@分隔,参数名 mappingRequestParamterServiceParameter取值。

        

    五、Service代码开辟

            由于web service的代码已根据配置文件主动生成了,所以这里的代码开辟现实上指的是为了实现web service的特定功能,须要通过反射机制调用的一些java方法的实现。

            例如,<serviceOperationsname="ServiceImpl.SampleService@@"

                           format="java">

        此处定义Web ServiceserviceOperationsformatjava,那么我们就须要实现其name中指定的class及方法,如本例中,要实现ServiceImpl class中的SampleService方法。具体方法及参数定义可见后面Web Service XML Configure文件的解释。

        再比如:<outputParameter>

                                    <name>sellCountList</name>

                                    <tag>NULL</tag>

                                    <mapping>ServiceImpl.getBeeSellCountList</mapping>

                           </outputParameter>

        此处定义此输出参数mappingServiceImpl类中的getBeeSellCountList方法,那么我们就须要实现ServiceImpl class中的getBeeSellCountList方法。具体方法及参数定义可见后面Web Service XML Configure文件的解释。

        要注意的是,定义在指定class中的方法都必须是静态方法,而且参数次序要和Web Service XML configure中定义一致。同一个class中的方法名及调用参数必须唯一。这些class文件的缺省路径在E:\java\Tomcat7022\conf\WSClass,也可以在web serviceconfigure文件中指定为conf目录下不同的活页夹作为class folder

        

    六、Web Service开辟实例

        此处给出一个simpleServiceproperties文文件实例和三个现实的Web ServiceXML configure 文件的实例。

        

    1. simpleService.properties

        sevice.version=1.0

        service.name=simpleService

        service.debug=true

        service.datasource=hiverService

        service.classfolder=WSClass

        Mapping2JavaMethod= ServiceImpl.simpleService

        Parameters=para1,para2,para3

        

    2. login.xml

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

        <service name="login" tag="loginCommand"version="1.0" debug="true" datasource="hiver"classfolder="WSClass">

                 <errormessageList>

                   <errormessage>Your account is locked.</errormessage>

                   <errormessage>Fail to pair your account.</errormessage>

                   <errormessage>API version is incorrect.</errormessage>

                 </errormessageList>      

        <!--request parameter -->

                 <requestParametersformat="xml">

                                    <required>Yes</required><!--isRequired-->

                           </requestParameter>

                           <requestParameter>

                                    <required>Yes</required>

                                    <mapping>psw</mapping>

                           </requestParameter>

                 </requestParameters>

                 <serviceOperations name="{callsp_login(?,?,?,?,?,?,?,?,?,?,?) }"

                           format="sp">

    七、注意事项

        1. 数据源加载失败的话,会缺省加载tomcat conf目录下的jdbc_ws.properties

        2. 定义在Web Service properties中作为Service mappingXML配置文件中作为parameter mappingJava方法,必须是publicstatic,返回字符串;

        3. 定义在XML配置文件中作为Service Operation mappingjava方法,七返回类型为List<String>,其值依次为各个Service Operation输出参数的取值。

        4. Tomcat conf目录下WSConfigure活页夹中的所有propertiesxml文件,都市被当做service配置文件而加载,只要其中有一个Debugtrue,整个Service就会重新生成,编译和主动部署发布。当系统正式运行后,可以把所有的service中的Debug配置的改为false,以进步Web Service的拜访效率。

    文章结束给大家分享下程序员的一些笑话语录: 关于编程语言
    如果 C++是一把锤子的话,那么编程就会变成大手指头。
    如果你找了一百万只猴子来敲打一百万个键盘,那么会有一只猴子会敲出一 段 Java 程序,而其余的只会敲出 Perl 程序。
    一阵急促的敲门声,“谁啊!”,过了 5 分钟,门外传来“Java”。
    如果说 Java 很不错是因为它可以运行在所有的操作系统上,那么就可以说 肛交很不错,因为其可以使用于所有的性别上。
