 related project in my another project microservices
VIII. Zipkin Intergation
 trace sub project aimed to support All database to be tracable and can record query parameters.
IX.Dataming support
 Support weka dataming tools
 Support simile dataming tools

 g. Excel read write utils support auto merge columns and customer header define.
XI.Develop Requirement
 open JDK 11 or above installed
 Spring 5.2.22
 Spring boot 2.5.14
 Other jar dependency see parent pom

I.Model Layer:Simple ORM tool, Support JAVA JPA or my BaseObject Annotation
 Demostration:(support Composite primary key) 
 1.Model Class
 exmaple: core/src/test/java/com/robin/core/test/model
 TestJPaModel Model annotation with java JPA
 TestModel model annotation with My model definition
 TestLob support for clob and blob
 usage:
 1.create class extends BaseObject;
 2.create parameter mapping DB cloumns
 using annotation
 @MappingEnity 
 -------------------------------------------------------------------
 |parameter |reference |
 |value |tableName |
 |schema |specify schema |
 |jdbcDao |Specify JdbcDao(can switch datasource) | |
 --------------------------------------------------------------------
 @MappingField
 ----------------------------------------------------------------------------------------
 |parameter |reference |
 |value |DB column name,if java param same as columnName,can unsign |
 |primary |if column is primary,set true |
 |increment |if column is autoincrement,set true |
 |sequenceName |column insert with sequence,set sequenceName |
 |required |column is not null |
 |datatype |if column is clob or blob,set "clob" or "blob" |
 |precise |precise |
 |scale |scale |
 |length |length |
 ----------------------------------------------------------------------------------------
 when save or update,Entity will verify use Annotation
 
 Composite Primary Key,see example core/src/test/java/com/robin/core/test/model/TestMutiPK
 
 2.Dao Layer:
 use com.robin.core.base.dao.JdbcDao,no need to Generate new Class
 
 3.Service Layer
 exmaple: core/src/test/java/com/robin/core/test/service 
 base class:
 main function
 -------------------------------------------------------------------------
 |function name |description |
 ------------------------------------------------------------------------|
 |saveEntity |insert to DB |
 |updateEntity |update to DB |
 |deleteEntity |delete by key array |
 |getEntity |select by id |
 |queryByField |query with specify column and value |
 |queryBySelectId |query with config query |
 ------------------------------------------------------------------------ 
 
 4.Query Configuration XML 
 4.1 Config Spring Bean
 using Config file 

 <bean id="queryFactory" class="com.robin.core.query.util.QueryFactory" autowire="byName">
 <property name="xmlConfigPath" value="classpath:query"></property>
 </bean> 

 xmlConfigPath support three input
 I.if not assign value,read config xml from classpath:queryConfig
 II. classpath:query 
 III.jarpath:query read config from jar base Path with relative path
 
 using config class
 @Bean(name="queryFactory")
 public QueryFactory getQueryFactory(){
 QueryFactory factory=new QueryFactory();
 factory.setXmlConfigPath(queryConfigPath);
 return factory;
 }
 4.1 config XML File
 in xmlConfigPath Path ,add xml file content

 <SQLSCRIPT ID="$_GETCODESET">
 <FROMSQL>from t_sys_code a,t_sys_codeset b where a.CS_ID=b.ID and ${queryString}</FROMSQL>
 <FIELD>a.ITEM_NAME as ITEMNAME,a.ITEM_VALUE as ITEMVALUE</FIELD>
 </SQLSCRIPT> 

 SQLSCRIPT ID refrer to queryBySelectId selectId.example see core test. 
	5.mybatis like QueryMapper

			<mapper namespace="com.robin.test.query1">
			<resultMap id="rsMap1" type="com.robin.core.test.model.TestModel">
				<result column="id" property="id" jdbcType="BIGINT" />
				<result column="name" property="name" jdbcType="VARCHAR" />
				<result column="code_desc" property="description" jdbcType="VARCHAR" />
				<result column="cs_id" property="csId" jdbcType="BIGINT" />
				<result column="create_time" property="createTime" jdbcType="TIMESTAMP" />
			</resultMap>
			<sql id="sqlpart1">
				id,name,code_desc,cs_id,create_time
			</sql>
			<sql id="sqlpart2">
				name,code_desc,cs_id,create_time
			</sql>
			<select id="select1" resultMap="rsMap1">
				select
				<include refid="sqlpart1" />
				 from t_test where 1=1
				<script lang="js" id="test1" resultMap="rsMap1">
					var returnstr="";
					if(name!=null){
						returnstr+=" and name like :name";
					}
					if(description!=null){
						returnstr+=" and code_desc like :description";
					}
					if(csId!=null){
						returnstr+=" and cs_id=:csId";
					}
					returnstr;
				</script>
			</select>
			<insert id="insert1" resultMap="rsMap1" parameterType="com.robin.core.test.model.TestModel" useGeneratedKeys="true" keyProperty="id">
				insert into t_test (
				<script lang="js" id="test2">
					var returnstr="";
					if(name!=null){
						returnstr+="name,"
					}
					if(description!=null){
						returnstr+="code_desc,"
					}
					if(csId!=null){
						returnstr+="cs_id,"
					}
					returnstr+="create_time";
				</script>
				) values (
				<script lang="js" id="test3">
					var returnstr="";
					if(name!=null){
						returnstr+=":name,";
					}
					if(description!=null){
						returnstr+=":description,";
					}if(csId!=null){
						returnstr+=":csId,";
					}
					returnstr+="sysdate()";
				</script>
				)
			</insert>
			<batch id="batch1" resultMap="rsMap1" parameterType="com.robin.core.test.model.TestModel">
				insert into t_test
				<include refid="sqlpart2" />
				values (:name,:description,:csId,sysdate())
			</batch>
			<update id="update1" resultMap="rsMap1" parameterType="com.robin.core.test.model.TestModel">
				update t_test set
				<script lang="js" id="test4">
					var returnstr="";
					if(name!=null){
						returnstr+="name=:name,";
					}
					if(description!=null){
						returnstr+="code_desc=:description,";
					}
					if(csId!=null){
						returnstr+="cs_id=:csId,";
					}
					returnstr.substr(0,returnstr.length-1);
				</script>
				 where id=:id
			</update>
			<delete id="del1" parameterType="">
			</delete>
		</mapper>

	no need to generate Mapper class,Only need QueryMapper xml file
	exmaple: core/src/test/java/com/robin/core/test/db/JdbcDaoTest testQueryAndInsertMapper
	
	insert update delete segement support script rather than ognl
 
 4.Controller layer
 BaseCrudController basic Single Model base controller, exmaple see example/config-exmaple
		BaseCrudDhtmlxController dhtmlxGrid base controller,make it easy to develop web and controller.
		
	upon feature aim to simplify the work to develop standard MVC java code.
