相关的依赖以及添加，不知道如下问题是如何导致，求解！ 已添加的依赖有： flink-connector-mysql-cdc flink-format-changelog-json flink-json
报错信息如下： java.util.ServiceConfigurationError: org.apache.flink.table.factories.Factory: Provider com.alibaba.ververica.cdc.formats.json.ChangelogJsonFormatFactory could not be instantiated at java.util.ServiceLoader.fail(ServiceLoader.java:232) at java.util.ServiceLoader.access$100(ServiceLoader.java:185) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:384) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:404) at java.util.ServiceLoader$1.next(ServiceLoader.java:480) at java.util.Iterator.forEachRemaining(Iterator.java:116) at org.apache.flink.table.factories.FactoryUtil.discoverFactories(FactoryUtil.java:342) at org.apache.flink.table.factories.FactoryUtil.discoverFactory(FactoryUtil.java:221) at org.apache.flink.table.factories.FactoryUtil.getDynamicTableFactory(FactoryUtil.java:326) at org.apache.flink.table.factories.FactoryUtil.createTableSource(FactoryUtil.java:118) at org.apache.flink.table.planner.plan.schema.CatalogSourceTable.buildTableScan(CatalogSourceTable.scala:135) at org.apache.flink.table.planner.plan.schema.CatalogSourceTable.toRel(CatalogSourceTable.scala:78) at org.apache.calcite.sql2rel.SqlToRelConverter.toRel(SqlToRelConverter.java:3492) at org.apache.calcite.sql2rel.SqlToRelConverter.convertIdentifier(SqlToRelConverter.java:2415) at org.apache.calcite.sql2rel.SqlToRelConverter.convertFrom(SqlToRelConverter.java:2102) at org.apache.calcite.sql2rel.SqlToRelConverter.convertFrom(SqlToRelConverter.java:2051) at org.apache.calcite.sql2rel.SqlToRelConverter.convertSelectImpl(SqlToRelConverter.java:661) at org.apache.calcite.sql2rel.SqlToRelConverter.convertSelect(SqlToRelConverter.java:642) at org.apache.calcite.sql2rel.SqlToRelConverter.convertQueryRecursive(SqlToRelConverter.java:3345) at org.apache.calcite.sql2rel.SqlToRelConverter.convertQuery(SqlToRelConverter.java:568) at org.apache.flink.table.planner.calcite.FlinkPlannerImpl.org$apache$flink$table$planner$calcite$FlinkPlannerImpl$$rel(FlinkPlannerImpl.scala:164) at org.apache.flink.table.planner.calcite.FlinkPlannerImpl.rel(FlinkPlannerImpl.scala:151) at org.apache.flink.table.planner.operations.SqlToOperationConverter.toQueryOperation(SqlToOperationConverter.java:789) at org.apache.flink.table.planner.operations.SqlToOperationConverter.convertSqlQuery(SqlToOperationConverter.java:761) at org.apache.flink.table.planner.operations.SqlToOperationConverter.convert(SqlToOperationConverter.java:238) at org.apache.flink.table.planner.delegation.ParserImpl.parse(ParserImpl.java:78) at org.apache.flink.table.api.internal.TableEnvironmentImpl.executeSql(TableEnvironmentImpl.java:684) at com.jfbank.searchrec.main.XfkOsProducts.main(XfkOsProducts.java:31) Caused by: java.lang.NoClassDefFoundError: org/apache/flink/formats/json/JsonOptions at com.alibaba.ververica.cdc.formats.json.ChangelogJsonFormatFactory.<clinit>(ChangelogJsonFormatFactory.java:53) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:442) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:380) ... 25 common frames omitted Caused by: java.lang.ClassNotFoundException: org.apache.flink.formats.json.JsonOptions at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 32 common frames omitted cljb...@163.com
