Spring Custom label Specification definition XSD

Introduction:

In spring's configuration file, all of the tags are spring-defined. <bean/>, and so on, with the definition of the specification, in order to allow users to fill out the normal available. You want to write a custom label, but first you need to understand the XML Schema Definition (XSD).

Label Definition:

For the definition of this class label, Spring has the corresponding XSD definition document

Http://www.springframework.org/schema/beans

For XSD, simply the definition of a label for XML, there is no explanation for the XSD too much, see

Http://www.w3school.com.cn/schema/schema_example.asp

Here is a simple description of some of the definitions that are often encountered in the application.

Application Scenario:

The database connection is further encapsulated to simplify the configuration.

      from the original configuration: XML code   <bean id= "DataSource"         class= "Org.springframework.jdbc.datasource.DriverManagerDataSource" >        <property name= "Driverclassname"  value= "Com.mysql.jdbc.Driver" ></property>        <property name= "url"             value= "jdbc:mysql://localhsost/freebug?useunicode=true&amp;characterencoding=utf8&amp; Autoreconnect=true "></property>       <property name=" username " >           <value>root</value>       </property>       <property name= "Password" >           <value>root</value>       </property>   </bean>      <!--  session  -->    <bean id= "sqlmapclient"  class= "Org.springframework.orm.ibatis.SqlMapClientFactoryBean" >        <property name= "configlocation"  value= "classpath: Sqlmapcommonconfig.xml " />       <property name=" DataSource "  ref= "DataSource"  />   </bean>   

Instead: XML code <mysql:client id= "Sqlmapclient" datasouceip= "Localhsost" characterencoding= "" UTF8 "fr Eebug "username=" root "password=" root "configlocation=" Classpath:SqlMapCommonConfig.xml "/>

From here, the configuration is handled in a simplified form. Many other information properties can also be restricted by default and regular.

How to make the above configuration can be set up, which requires the definition of the XSD specification for this tag.

Label Definition

The    definition is as follows: XML code    <?xml version= "1.0"  encoding= "UTF-8"?>   <xsd: schema xmlns= "Http://sammor.javaeye.com/schema/tags"        xmlns:xsd= "http:/ /www.w3.org/2001/xmlschema " xmlns:beans=" Http://www.springframework.org/schema/beans "        targetnamespace= "Http://sammor.javaeye.com/schema/tags"         elementformdefault= "qualified"  attributeformdefault= "unqualified" >        <xsd:import namespace= "Http://www.springframework.org/schema/beans"  />        <xsd:element name= "Client" >            <xsd:annotation>               < xsd:documentation>connect to mysql</xsd:documentation>       & nbsp;   </xsd:annotation>           <
