好了大概配置就这样，博主知识技术有限，这里就不仔细写了，如果不懂，没关系，博主把代码也上传，欢迎大家参考学习。

# 简单的说：WebService即Web服务，它是一种跨编程语言和跨操作系统平台的远程调用技术。 #

实现不同系统，进程间，任何地点的数据交换，webservice是跨语言技术。webservice是基于HTTP与XML的技术。

采用标准SOAP(Simple Object Access Protocol)协议传输，soap属于W3C标准。Soap协议是基于http的应用层协议，传输是xml数据。

采用wsdl作为描述语言即webservice使用说明书，wsdl属于w3c标准。

xml是webservice的跨平台的基础，xml主要的 优点在于它既与平台无关，又与厂商无关。

什么是webservice?

概述二： Webservice是一套远程调用技术规范;

远程调用RPC, 实现了系统与系统进程间的远程通信.

java领域有很多可实现远程通讯的技术，如：RMI(Socket + 序列化)、Binary-RPC(Http+二进制, 代表Hessian)、XML-RPC(Http+XML, 代表Burlap, WebService用的SOAP)、JMS(使用消息机制)、Mina(使用NIO)等, 底层都是基于http/socket和网络IO来实现的.

从效率上来讲, RMI > Hessian >> Burlap >> web service.

底层传输简介：

![70][]

## 1.1. **WebService三要素** ##

**1.1.1. ****SOAP (简易对象访问协议)**

数据传输的协议（http+xml） 基于http协议传输...传输的内容是xml

### 1.1.2. **WSDL (Web services 描述语言 说明书)** ###

定义webservice数据是如何传输的，数据的内容 以及相关协议描述和定义

客户端通过wsdl文件获取本地代理类(也叫桩)

wsimport  jdk提供!  -s  -d  -p

### 1.1.3. **UDDI (webservice注册地)** ###

注册webService服务

整合和发现WebService服务—类似目录服务器

以上大概介绍了一下，那么接下来就代码开干吧：

整个项目结构如下图：

    </project>

二：加载相应的配置：log4j.properties  ,mybatis.cfg.xml  ,mysqlproperties,spring-servlet.xml

![20190316164935269.png][]

2.1：log4j.properties  具体如下：

log4j.rootCategory=WARN, stdout , R
    
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=[QC] %p [%t] %C.%M(%L) | %m%n
    
    log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.R.File=D:\\apache-tomcat-7.0.52\\logs\\qc.log
    log4j.appender.R.layout=org.apache.log4j.PatternLayout
    1log4j.appender.R.layout.ConversionPattern=%d-[TS] %p %t %c - %m%n
    
    log4j.logger.com.neusoft=WARN
    log4j.logger.com.opensymphony.oscache=ERROR
    log4j.logger.net.sf.navigator=ERROR
    log4j.logger.org.apache.commons=ERROR
    log4j.logger.org.apache.struts=WARN
    log4j.logger.org.displaytag=ERROR
    log4j.logger.org.springframework=WARN
    log4j.logger.com.ibatis.db=WARN
    log4j.logger.org.apache.velocity=FATAL
    
    log4j.logger.com.canoo.webtest=WARN
    
    log4j.logger.org.hibernate.ps.PreparedStatementCache=WARN
    log4j.logger.org.hibernate=WARN
    log4j.logger.org.logicalcobwebs=WARN

2.2mybatis.cfg.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration PUBLIC 
    	"-//mybatis.org//DTD Config 3.0//EN" 
    	"http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    
    
    	<settings>
    		 <setting name="logImpl" value="STDOUT_LOGGING"/>
    	</settings>
    
    	
    	
    	<typeAliases>
    		<package name="com.hong.domain"/>
    	</typeAliases>
    </configuration>

2.3mysqlproperties配置如下：记得修改成你自己对应的数据库与用户名与密码：

mysql.driver=com.mysql.jdbc.Driver
    mysql.url=jdbc:mysql://localhost:3306/test5?useUnicode=true&characterEncoding=utf8
    mysql.username=root
    mysql.password=123456

2.4：springmvc-servlet.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    		xmlns:p="http://www.springframework.org/schema/p"
    		xmlns:tx="http://www.springframework.org/schema/tx"
    		xmlns:context="http://www.springframework.org/schema/context"
    		xmlns:mvc="http://www.springframework.org/schema/mvc"
    	   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.springframework.org/schema/beans  
            http://www.springframework.org/schema/beans/spring-beans.xsd

            http://www.springframework.org/schema/context/spring-context-3.2.xsd

            http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
            http://www.springframework.org/schema/tx  
            http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
            " >
            <context:annotation-config></context:annotation-config>
            <context:component-scan base-package="com.hong"></context:component-scan>
            <mvc:annotation-driven></mvc:annotation-driven>
            <mvc:default-servlet-handler/>
            
            
            
            <bean id="propertyPlaceholder" 
            class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    	        <property name="locations">
    	        	<list><value>classpath:mysql.properties</value></list>
    	        </property>
            </bean>
            
            <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
            p:driverClassName="${mysql.driver}" p:url="${mysql.url}"
            p:username="${mysql.username}" p:password="${mysql.password}"
            p:initialSize="3" p:maxIdle="10"
            ></bean>
            
            <bean id="factory" class="org.mybatis.spring.SqlSessionFactoryBean"
            p:dataSource-ref="dataSource" p:configLocation="classpath:mybatis.cfg.xml"
            p:mapperLocations="classpath*:com/hong/dao/*.xml"
            >
              
            </bean>
            
            <bean id="configurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer"
            p:basePackage="com.hong.dao" p:sqlSessionFactoryBeanName="factory"
            ></bean>
            
            
             <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
             p:dataSource-ref="dataSource"
             ></bean>
             
             
             
             <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
             p:viewClass="org.springframework.web.servlet.view.JstlView" 
             p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"
             ></bean>
             <tx:annotation-driven transaction-manager="txManager"/>
              
    		</beans>

运行效果：这样就可以调用其他系统传过来的数据了
