Infinite recursion when requesting application/vnc.api+json data [DATAREST-767]
Gabriel Bauman opened DATAREST-767 and commented
I have a test Spring Boot application with a single entity Contact and CrudRepository at /contact. There are no entity relationships.
When there are no entities in the database, the request:
curl 'http://localhost:8080/contacts' -H 'Accept: application/vnd.api+json'
Returns:
{
"links" : [ {
"rel" : "self",
"href" : "http://localhost:8080/contacts"
}, {
"rel" : "profile",
"href" : "http://localhost:8080/profile/contacts"
} ],
"content" : [ {
"collectionValue" : true,
"rel" : null,
"relTargetType" : "sdr.Contact",
"value" : [ ]
} ]
}
But, when I add a record to the database, the same curl request is infinitely recursive:
{
"links" : [ {
"rel" : "self",
"href" : "http://localhost:8080/contacts"
}, {
"rel" : "profile",
"href" : "http://localhost:8080/profile/contacts"
} ],
"content" : [ {
"id" : 1,
"firstName" : "Test",
"lastName" : "Person",
"embeddeds" : {
"content" : [ ]
},
"propertyAccessor" : {
"bean" : {
"id" : 1,
"firstName" : "Test",
"lastName" : "Person"
}
},
"persistentEntity" : {
"idProperty" : {
"name" : "id",

Hmm, it appears that there are a number of related bugs. See DATAREST-733 and DATAREST-734

Have the same problem with "x-spring-data-verbose+json" and "x-spring-data-compact+json".
Invinite loop of:
"association" : false, "owner" : { "idProperty" : { "name" : "id", "rawType" : "java.lang.Integer", "field" : { "name" : "id", "type" : "java.lang.Integer", "modifiers" : 2, "annotations" : [ { }, { } ], "declaredAnnotations" : [ { }, { } ], "synthetic" : false, "declaringClass" : "Access", "enumConstant" : false, "genericType" : "java.lang.Integer", "annotatedType" : { "type" : "java.lang.Integer", "annotations" : [ ], "declaredAnnotations" : [ ] }, "accessible" : true }, "association" : false, "owner" : { ....
