java - NotSerializableException on serialization of objects currently shown by Vaadin -


i notserializableexception when want serialize object shown vaadin.

the structure this:

vaadin ui <--- serialize / deserialize --- > hibernate/jpa postgres database

vaadin shows objects requested database via ipc, when manipulate object , want save again serializing , sending on controller following exception:

java.io.notserializableexception: org.springframework.boot.context.embedded.annotationconfigembeddedwebapplicationcontext  	at java.io.objectoutputstream.writeobject0(objectoutputstream.java:1183)  	at java.io.objectoutputstream.defaultwritefields(objectoutputstream.java:1547)  	at java.io.objectoutputstream.writeserialdata(objectoutputstream.java:1508)  	at java.io.objectoutputstream.writeordinaryobject(objectoutputstream.java:1431)  	at java.io.objectoutputstream.writeobject0(objectoutputstream.java:1177)  	at java.io.objectoutputstream.writeobject(objectoutputstream.java:347)  	at java.util.linkedlist.writeobject(linkedlist.java:1118)  	at sun.reflect.generatedmethodaccessor38.invoke(unknown source)  	at sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)  	at java.lang.reflect.method.invoke(method.java:606)

i tried to:

request -> manipulate -> save | works

request -> show in vaadin -> manipulate in vaadin-> save | doesn't work

why serializer want annotationconfigembeddedwebapplicationcontext , there workaround? can remove beforehand?

spring components not serializable (or should not serialized @ all).

injecting spring components in vaadin components linked vaadin ui tricky because them should declared transient , re-populated after deserialization..

i wrote small library jdal-aop ease process, using spring-aop serializable proxies.

for example

public class mainlayout extends verticallayout {      @autowired     @serializableproxy  // make dao serializable     private customerdao customerdao; }

it useful you.
