Solr has an error with the specified unknown field type 'cndate'' when using DIH. How to modify the specification?

Unknown fieldType "cndate" specified on field birth. appears whenever I use type= "cndate"

when I comment on this line of code, the program can run. Not only "cndate", but also "int" and "text_ik" will report the same mistake.

Code of the schema.xml file 

<field name="userName" type="string" indexed="true" stored="true" omitNorms="true"/>
<field name="sex" type="boolean" indexed="true" stored="true" omitNorms="true"/>
<field name="birth" type="cndate" indexed="true" stored="true" omitNorms="true"/>
<field name="salary" type="int" indexed="true" stored="true" omitNorms="true"/>
<field name="text" type="text_ik" indexed="true" stored="true" omitNorms="true" multiValued="false"/>
<field name="author" type="string" indexed="true" stored="true"/>
<field name="title" type="string" indexed="true" stored="true"/>

<field name="size" type="long" indexed="true" stored="true" />
<field name="lastModified" type="cndate" indexed="true" stored="true"/>

<field name="id" type="string" indexed="true" stored="true" required="false" multiValued="false" />

what result do you expect? What is the error message actually seen?

error problem log: new2_core: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core new2_core: Can"t load schema cndate" specified on field birth cndate" specified on field birth

how do you specify these types in solr?

there may be no "cndata", "int" and "text_ik" types in the solr7.5 version. Check the source code to find 

<dynamicField name="*_i"  type="pint"    indexed="true"  stored="true"/>
<dynamicField name="*_is" type="pints"    indexed="true"  stored="true"/>
<dynamicField name="*_s"  type="string"  indexed="true"  stored="true" />
<dynamicField name="*_ss" type="strings"  indexed="true"  stored="true"/>
<dynamicField name="*_l"  type="plong"   indexed="true"  stored="true"/>
<dynamicField name="*_ls" type="plongs"   indexed="true"  stored="true"/>
<dynamicField name="*_t" type="text_general" indexed="true" stored="true" multiValued="false"/>
<dynamicField name="*_txt" type="text_general" indexed="true" stored="true"/>
<dynamicField name="*_b"  type="boolean" indexed="true" stored="true"/>
<dynamicField name="*_bs" type="booleans" indexed="true" stored="true"/>

<dynamicField name="*_ds" type="pdoubles" indexed="true"  stored="true"/>
<dynamicField name="random_*" type="random"/>
<!-- Type used for data-driven schema, to add a string copy for each text field -->
<dynamicField name="*_str" type="strings" stored="false" docValues="true" indexed="false" useDocValuesAsStored="false"/>
<dynamicField name="*_dt"  type="pdate"    indexed="true"  stored="true"/>
<dynamicField name="*_dts" type="pdate"    indexed="true"  stored="true" multiValued="true"/>
<dynamicField name="*_p"  type="location" indexed="true" stored="true"/>
<dynamicField name="*_srpt"  type="location_rpt" indexed="true" stored="true"/>
<!-- payloaded dynamic fields -->
<dynamicField name="*_dpf" type="delimited_payloads_float" indexed="true"  stored="true"/>
<dynamicField name="*_dpi" type="delimited_payloads_int" indexed="true"  stored="true"/>
<dynamicField name="*_dps" type="delimited_payloads_string" indexed="true"  stored="true"/>
<dynamicField name="attr_*" type="text_general" indexed="true" stored="true" multiValued="true"/>

represents different types of code. Change "cndata" to "pdata", "int" to "pint", and "text_ik" to "text_general" to run
