javers設(shè)計(jì)了幾張表，這里簡(jiǎn)單介紹下
jv_snapshot
主要用來(lái)存儲(chǔ)對(duì)象的每次變更操作以及變更的屬性值。
-- ----------------------------
-- Table structure for jv_snapshot
-- ----------------------------
DROP TABLE IF EXISTS "public"."jv_snapshot";
CREATE TABLE "public"."jv_snapshot" (
"snapshot_pk" int8 NOT NULL,
"type" varchar(200) COLLATE "default",
"version" int8,
"state" text COLLATE "default",
"changed_properties" text COLLATE "default",
"managed_type" varchar(200) COLLATE "default",
"global_id_fk" int8,
"commit_fk" int8
)
WITH (OIDS=FALSE);
ALTER TABLE "public"."jv_snapshot" OWNER TO "postgres";
-- ----------------------------
-- Primary key structure for table jv_snapshot
-- ----------------------------
ALTER TABLE "public"."jv_snapshot" ADD PRIMARY KEY ("snapshot_pk") NOT DEFERRABLE INITIALLY IMMEDIATE;
-- ----------------------------
-- Indexes structure for table jv_snapshot
-- ----------------------------
CREATE INDEX "jv_snapshot_commit_fk_idx" ON "public"."jv_snapshot" USING btree(commit_fk "pg_catalog"."int8_ops" ASC NULLS LAST);
CREATE INDEX "jv_snapshot_global_id_fk_idx" ON "public"."jv_snapshot" USING btree(global_id_fk "pg_catalog"."int8_ops" ASC NULLS LAST);
-- ----------------------------
-- Foreign keys structure for table jv_snapshot
-- ----------------------------
ALTER TABLE "public"."jv_snapshot" ADD CONSTRAINT "jv_snapshot_commit_fk" FOREIGN KEY ("commit_fk") REFERENCES "public"."jv_commit" ("commit_pk") ON UPDATE NO ACTION ON DELETE NO ACTION NOT DEFERRABLE INITIALLY IMMEDIATE;
ALTER TABLE "public"."jv_snapshot" ADD CONSTRAINT "jv_snapshot_global_id_fk" FOREIGN KEY ("global_id_fk") REFERENCES "public"."jv_global_id" ("global_id_pk") ON UPDATE NO ACTION ON DELETE NO ACTION NOT DEFERRABLE INITIALLY IMMEDIATE;
jv_global_id
存儲(chǔ)了每次變更的id
-- ----------------------------
-- Table structure for jv_global_id
-- ----------------------------
DROP TABLE IF EXISTS "public"."jv_global_id";
CREATE TABLE "public"."jv_global_id" (
"global_id_pk" int8 NOT NULL,
"local_id" varchar(200) COLLATE "default",
"fragment" varchar(200) COLLATE "default",
"type_name" varchar(200) COLLATE "default",
"owner_id_fk" int8
)
WITH (OIDS=FALSE);
ALTER TABLE "public"."jv_global_id" OWNER TO "postgres";
-- ----------------------------
-- Primary key structure for table jv_global_id
-- ----------------------------
ALTER TABLE "public"."jv_global_id" ADD PRIMARY KEY ("global_id_pk") NOT DEFERRABLE INITIALLY IMMEDIATE;
-- ----------------------------
-- Indexes structure for table jv_global_id
-- ----------------------------
CREATE INDEX "jv_global_id_local_id_idx" ON "public"."jv_global_id" USING btree(local_id COLLATE "default" "pg_catalog"."text_ops" ASC NULLS LAST);
-- ----------------------------
-- Foreign keys structure for table jv_global_id
-- ----------------------------
ALTER TABLE "public"."jv_global_id" ADD CONSTRAINT "jv_global_id_owner_id_fk" FOREIGN KEY ("owner_id_fk") REFERENCES "public"."jv_global_id" ("global_id_pk") ON UPDATE NO ACTION ON DELETE NO ACTION NOT DEFERRABLE INITIALLY IMMEDIATE;
jv_commit
存儲(chǔ)了每次變更的時(shí)間、變更人
-- ----------------------------
-- Table structure for jv_commit
-- ----------------------------
DROP TABLE IF EXISTS "public"."jv_commit";
CREATE TABLE "public"."jv_commit" (
"commit_pk" int8 NOT NULL,
"author" varchar(200) COLLATE "default",
"commit_date" timestamp(6) NULL,
"commit_id" numeric(22,2)
)
WITH (OIDS=FALSE);
ALTER TABLE "public"."jv_commit" OWNER TO "postgres";
-- ----------------------------
-- Primary key structure for table jv_commit
-- ----------------------------
ALTER TABLE "public"."jv_commit" ADD PRIMARY KEY ("commit_pk") NOT DEFERRABLE INITIALLY IMMEDIATE;
-- ----------------------------
-- Indexes structure for table jv_commit
-- ----------------------------
CREATE INDEX "jv_commit_commit_id_idx" ON "public"."jv_commit" USING btree(commit_id "pg_catalog"."numeric_ops" ASC NULLS LAST);
支持自動(dòng)從SpringSecurity獲取auditor
public class SpringSecurityAuthorProvider implements AuthorProvider {
public SpringSecurityAuthorProvider() {
}
public String provide() {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
return auth == null?"unauthenticated":auth.getName();
}
}
也可以自定義，比如
@Bean
public AuthorProvider authorProvider() {
return new MockAuthorProvider();
}
jv_commit_property
用來(lái)存儲(chǔ)額外的信息，比如存儲(chǔ)了用戶id，順帶存一下用戶名等。
-- ----------------------------
-- Table structure for jv_commit_property
-- ----------------------------
DROP TABLE IF EXISTS "public"."jv_commit_property";
CREATE TABLE "public"."jv_commit_property" (
"property_name" varchar(200) NOT NULL COLLATE "default",
"property_value" varchar(600) COLLATE "default",
"commit_fk" int8 NOT NULL
)
WITH (OIDS=FALSE);
ALTER TABLE "public"."jv_commit_property" OWNER TO "postgres";
-- ----------------------------
-- Primary key structure for table jv_commit_property
-- ----------------------------
ALTER TABLE "public"."jv_commit_property" ADD PRIMARY KEY ("commit_fk", "property_name") NOT DEFERRABLE INITIALLY IMMEDIATE;
-- ----------------------------
-- Indexes structure for table jv_commit_property
-- ----------------------------
CREATE INDEX "jv_commit_property_commit_fk_idx" ON "public"."jv_commit_property" USING btree(commit_fk "pg_catalog"."int8_ops" ASC NULLS LAST);
CREATE INDEX "jv_commit_property_property_name_property_value_idx" ON "public"."jv_commit_property" USING btree(property_name COLLATE "default" "pg_catalog"."text_ops" ASC NULLS LAST, property_value COLLATE "default" "pg_catalog"."text_ops" ASC NULLS LAST);
-- ----------------------------
-- Foreign keys structure for table jv_commit_property
-- ----------------------------
ALTER TABLE "public"."jv_commit_property" ADD CONSTRAINT "jv_commit_property_commit_fk" FOREIGN KEY ("commit_fk") REFERENCES "public"."jv_commit" ("commit_pk") ON UPDATE NO ACTION ON DELETE NO ACTION NOT DEFERRABLE INITIALLY IMMEDIATE;
可以這樣自定義
@Bean
public CommitPropertiesProvider commitPropertiesProvider() {
return new CommitPropertiesProvider() {
@Override
public Map<String, String> provide() {
return ImmutableMap.of("key", "ok");
}
};
}
