From 6c262f1df549d07298431941bc08c71b9b2da6e8 Mon Sep 17 00:00:00 2001 From: rbygrave Date: Fri, 23 Jul 2021 16:50:24 +1200 Subject: [PATCH 01/26] JSON bean dirty detection via MD5 of JSON string content - MD5 of json content stored on EntityBeanIntercept for dirty detection - Only convert to JSON once (at dirty detection time). Store this json content on EntityBeanIntercept to later push to ScalarTypeJsonObjectMapper for bind Should consider alternative to extend BeanProperty rather than have these if blocks. --- .../io/ebean/bean/EntityBeanIntercept.java | 33 +++++++++ .../java/io/ebean/core/type/DataBinder.java | 11 +++ .../java/io/ebean/core/type/DataReader.java | 10 +++ .../java/io/ebean/core/type/ScalarType.java | 8 ++ .../server/deploy/BeanDescriptor.java | 4 +- .../server/deploy/BeanProperty.java | 47 ++++++++---- .../server/persist/dml/DmlHandler.java | 5 ++ .../dmlbind/BindablePropertyJsonInsert.java | 42 +++++++++++ .../dmlbind/BindablePropertyJsonUpdate.java | 35 +++++++++ .../persist/dmlbind/BindableRequest.java | 5 ++ .../persist/dmlbind/FactoryProperty.java | 7 ++ .../server/query/SqlBeanLoad.java | 11 ++- .../ebeaninternal/server/type/DataBind.java | 11 +++ .../server/type/RsetDataReader.java | 15 +++- .../type/ScalarTypeJsonObjectMapper.java | 52 ++++++++++++- .../org/tests/json/TestDbJson_Jackson3.java | 3 +- .../java/org/tests/json/TestDbJson_List.java | 12 ++- .../org/tests/model/json/EBasicPlain.java | 54 ++++++++++++++ .../model/json/TestJacksonPlainBean.java | 73 +++++++++++++++++++ 19 files changed, 404 insertions(+), 34 deletions(-) create mode 100644 ebean-core/src/main/java/io/ebeaninternal/server/persist/dmlbind/BindablePropertyJsonInsert.java create mode 100644 ebean-core/src/main/java/io/ebeaninternal/server/persist/dmlbind/BindablePropertyJsonUpdate.java create mode 100644 ebean-core/src/test/java/org/tests/model/json/EBasicPlain.java create mode 100644 ebean-core/src/test/java/org/tests/model/json/TestJacksonPlainBean.java diff --git a/ebean-api/src/main/java/io/ebean/bean/EntityBeanIntercept.java b/ebean-api/src/main/java/io/ebean/bean/EntityBeanIntercept.java index 28a088ce6..59a2450bd 100644 --- a/ebean-api/src/main/java/io/ebean/bean/EntityBeanIntercept.java +++ b/ebean-api/src/main/java/io/ebean/bean/EntityBeanIntercept.java @@ -91,6 +91,17 @@ public final class EntityBeanIntercept implements Serializable { private Object ownerId;
