解決springboot啟動(dòng)失敗的問(wèn)題('hibernate.dialect'?not?set)
springboot啟動(dòng)失敗的問(wèn)題
springboot版本是1.3.0.M1，連接的mysql版本為8，用spring-boot-starter-data-jpa操做數(shù)據(jù)庫(kù)
啟動(dòng)springboot報(bào)錯(cuò)如下

這一句比較關(guān)鍵：
Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
原來(lái)是Hibernate SQL方言沒(méi)有設(shè)置導(dǎo)致的，在properties文件中增加下面這行：
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
再啟動(dòng)springboot，這次啟動(dòng)成功了；
將Hibernate SQL方言整理如下表
| 數(shù)據(jù)庫(kù) | 方言 |
|---|---|
| DB2 | org.hibernate.dialect.DB2Dialect |
| DB2 AS/400 | org.hibernate.dialect.DB2400Dialect |
| DB2 OS390 | org.hibernate.dialect.DB2390Dialect |
| PostgreSQL | org.hibernate.dialect.PostgreSQLDialect |
| MySQL | org.hibernate.dialect.MySQLDialect |
| MySQL with InnoDB | org.hibernate.dialect.MySQLInnoDBDialect |
| MySQL with MyISAM | org.hibernate.dialect.MySQLMyISAMDialect |
| Oracle (any version) | org.hibernate.dialect.OracleDialect |
| Oracle 9i/10g | org.hibernate.dialect.Oracle9Dialect |
| Sybase | org.hibernate.dialect.SybaseDialect |
| Sybase Anywhere | org.hibernate.dialect.SybaseAnywhereDialect |
| Microsoft SQL Server | org.hibernate.dialect.SQLServerDialect |
| SAP DB | org.hibernate.dialect.SAPDBDialect |
| Informix | org.hibernate.dialect.InformixDialect |
| HypersonicSQL | org.hibernate.dialect.HSQLDialect |
| Ingres | org.hibernate.dialect.IngresDialect |
| Progress | org.hibernate.dialect.ProgressDialect |
| Mckoi SQL | org.hibernate.dialect.MckoiDialect |
| Interbase | org.hibernate.dialect.InterbaseDialect |
| Pointbase | org.hibernate.dialect.PointbaseDialect |
| FrontBase | org.hibernate.dialect.FrontbaseDialect |
| Firebird | org.hibernate.dialect.FirebirdDialect |
springboot出現(xiàn)'hibernate.dialect'not set
在application.properties內(nèi)寫下這兩條
雙保險(xiǎn)！
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect spring.jpa.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
