java - Nested Thymeleaf Templates in Spring -


short version

how 1 supposed make nested templates in thymeleaf when using spring? appears asterisk notation not supported ("*{mailingaddress}") inside th:object attributes in spring. there work-around / different tag use?

long version

for example, let's have these classes:

class address { string street; } class person { address mailingaddress; address shippingaddress; } class order { int orderno; person customer; }

so make address.html thymeleaf template:

<span th:text="*{street}"></span>

we test sample address. looks good.

and make person.html thymeleaf template references address so:

<span th:text="*{firstname}"></span> <span th:object="${person.shippingaddress}">     <span th:include="fragments/address :: address"></span> </span>

and test example person. reference same template , set context ${person.mailingaddress}. far good.

now let's make our order template. only, hey, wait. earlier, in our person.html file said ${person.shippingaddress} now need ${order.customer.shippingaddress}. if not using spring i'd put following person.html:

<span th:text="*{firstname}"></span> <span th:object="*{shippingaddress}">     <span th:include="fragments/address :: address"></span> </span>

that way, no matter path getting here have care current context has shippingaddress. use person.html directly within order.html template.

unfortunately am in spring, following exception:

org.thymeleaf.exceptions.templateprocessingexception:      expression used object selection *{shippingaddress},     not valid: variable expressions (${...})     allowed in 'th:object' attributes in spring-enabled environments.      (include:510) @ org.thymeleaf.spring4.processor.attr.springobjectattrprocessor.validateselectionvalue(springobjectattrprocessor.java:73) @ org.thymeleaf.standard.processor.attr.abstractstandardselectionattrprocessor.getnewselectiontarget(abstractstandardselectionattrprocessor.java:69) @ org.thymeleaf.processor.attr.abstractselectiontargetattrprocessor.processattribute(abstractselectiontargetattrprocessor.java:61)

to move forward must duplicate nested templates. in example, have 1 person.html th:object="${person.mailingaddress}" calling address.html, , duplicate of person.html called ordercustomer.html change line th:object="${order.customer.mailingaddress}", otherwise identical.

is there work-around out there let me re-use templates?

you can report bug thymeleaf developers in github, or fork project add functionality , convince daniel fernández accept it.

https://github.com/thymeleaf/thymeleaf/issues

or else, available in stackoverflow. can send him message posibility of integrating functionality

https://stackoverflow.com/users/550664/daniel-fern%c3%a1ndez

apart there nothing can rather stick approach of putting th:object="${person.mailingaddress}" , th:object="${order.customer.mailingaddress}" outside each import.
