How to custom Spring Batch DelimitedLineTokenizer -

-

i have 2 file types insert in database.

format : aa;bb;cc , aa;bb;cc;dd;ee

this flatfileitemreader :

    <bean name="readercontracttoaddintoprv" class="org.springframework.batch.item.file.flatfileitemreader">         <property name="comments" value="#" />         <property name="linestoskip" value="1" />         <property name="strict" value="false" />         <property name="linemapper">             <bean class="org.springframework.batch.item.file.mapping.defaultlinemapper">                 <property name="fieldsetmapper">                     <bean class="net.wl.batchs.fieldsetmapper.linetocreateintoprvfieldsetmapper" />                 </property>                 <property name="linetokenizer">                     <bean class="org.springframework.batch.item.file.transform.delimitedlinetokenizer">                         <property name="delimiter" value=";"/>                         <property name="names" value="aa,bb,cc,dd,ee" />                     </bean>                 </property>             </bean>         </property>     </bean>

i want setup works both types of files.

for moment, have :

org.springframework.batch.item.file.transform.incorrecttokencountexception: incorrect number of tokens found in record: expected 3 actual 5

do have ideas?

thank you.

edit : after correction :

<bean name="readercontracttoaddintoprv" class="org.springframework.batch.item.file.flatfileitemreader">     <property name="comments" value="#" />     <property name="linestoskip" value="1" />      <property name="strict" value="false" />     <property name="linemapper">         <bean class="org.springframework.batch.item.file.mapping.defaultlinemapper" p:linetokenizer-ref="multilinefiletokenizer">             <property name="fieldsetmapper">                 <bean class="net.wl.batchs.fieldsetmapper.linetocreateintoprvfieldsetmapper" />             </property>         </bean>     </property> </bean>  <bean id="multilinefiletokenizer" class="org.springframework.batch.item.file.transform.patternmatchingcompositelinetokenizer">   <property name="tokenizers">     <map>       <entry key="*;*;*;*;*" value-ref="nsce_iccid_msisdn_login_pwd"/>       <entry key="*;*;*" value-ref="nsce_iccid_msisdn"/>       <entry key="*" value-ref="headerdefault"/>     </map>   </property> </bean>  <bean id="parentlinetokenizer" class="org.springframework.batch.item.file.transform.delimitedlinetokenizer" abstract="true">     <property name="delimiter" value=";"/> </bean> <bean id="nsce_iccid_msisdn_login_pwd" parent="parentlinetokenizer">     <property name="names" value="nsce,iccid,msisdn,login,pwd" /> </bean> <bean id="nsce_iccid_msisdn" parent="parentlinetokenizer">     <property name="names" value="nsce,iccid,msisdn" /> </bean> <bean id="headerdefault" parent="parentlinetokenizer">     <property name="names" value="nsce,iccid,msisdn" /> </bean>

the issue isn't tokenizer. you'll have use patternmatchingcompositelinemapper (http://docs.spring.io/spring-batch/trunk/apidocs/org/springframework/batch/item/file/mapping/patternmatchingcompositelinemapper.html). allow create pattern each line type have , associate appropriate linetokenizer.

you can see linemapper in action in our samples here: https://github.com/spring-projects/spring-batch/blob/master/spring-batch-samples/src/main/resources/jobs/multilineorderinputtokenizers.xml
