作者的應(yīng)用有多個(gè)數(shù)據(jù)源，兩個(gè)pg和释漆，一個(gè)mysql
如果應(yīng)用第一個(gè)初始化的數(shù)據(jù)源是pg悲没，那應(yīng)用就會(huì)一直使用pg的dialect繼續(xù)初始化之后的數(shù)據(jù)源
必須在mysql的數(shù)據(jù)源配置類中手動(dòng)指定為mysql的dialect
網(wǎng)上大多數(shù)是在配置文件中指定
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
如果你的數(shù)據(jù)源都是同一類型，就不會(huì)有問(wèn)題
private Map<String, Object> getVendorProperties() {
Map<String, Object> ret = jpaProperties.getHibernateProperties(new HibernateSettings());
ret.put("hibernate.dialect", "org.hibernate.dialect.MySQL5InnoDBDialect");
return ret;
}
