Access to DialectResolutionInfo cannot be null when ‘hibernate.dialect’ not set
去了stackoverflow： java - Spring Boot JPA - Access to DialectResolutionInfo cannot be null when ‘hibernate.dialect’ not set - Stack Overflow 不是PostgreSQL，那就换成mysql的嘛：
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Kingbase8Dialect
Could not load requested class : org.hibernate.dialect.Kingbase8Dialect
增加方言类： class Kingbase8Dialect extends PostgreSQL9Dialect
@Override
public IdentifierHelper buildIdentifierHelper(IdentifierHelperBuilder builder, DatabaseMetaData dbMetaData)
throws SQLException {
if (dbMetaData == null) {
builder.setQuotedCaseStrategy(IdentifierCaseStrategy.MIXED);
}
builder.applyIdentifierCasing( dbMetaData );
builder.applyReservedWords( dbMetaData );
builder.applyReservedWords( AnsiSqlKeywords.INSTANCE.sql2003() );
builder.applyReservedWords(super.getKeywords());
builder.setNameQualifierSupport( getNameQualifierSupport() );
builder.setUnquotedCaseStrategy(IdentifierCaseStrategy.MIXED);
return builder.build();
Caused by: java.lang.RuntimeException: Driver org.postgresql.Driver claims to not accept jdbcUrl, jdbc:kingbase8:
增加配置： spring.datasource.ddb.driver-class-name=com.kingbase8.Driver
couldn’t deduct database type from database product name ‘KingbaseES’
