Spring Mvc Hibernate编码/多行导入sql

Question

我正在研究Spring MVC,

在项目启动时,我已设置database为sql 使用hibernate配置导入默认值hibernate.hbm2ddl.import_files.里面的数据import.sql用UTF-8.编码.

控制台输出

 ERROR: org.hibernate.tool.hbm2ddl.SchemaExport - HHH000388:
 Unsuccessful: INSERT INTO menu (id, DATE_CREATED, DATE_DELETED,
 DATE_UPDATED, TITLE_ENG, TITLE_GEO, TITLE_RUS, ENABLED, PARENT_ID,
 URL, SITE_ID, USER_ID) VALUES 

 ERROR:

Answer 1

1. 确保将JDBC驱动程序设置为使用UTF-8:

   jdbc:mysql://dbname?useUnicode=true&characterEncoding=utf-8

2. 在persistence.xml,设置hibernate连接字符集:

   <property name="hibernate.connection.charSet" value="UTF-8"/>

如果您的resources/import.sql文件是多行的,请添加:

<property 
  name="hibernate.hbm2ddl.import_files_sql_extractor"
  value="org.hibernate.tool.hbm2ddl.MultipleLinesSqlCommandExtractor" 
/>

或者用于Spring Boot,在application.properties:

spring.jpa.properties.hibernate.connection.charSet=UTF-8
spring.jpa.properties.hibernate.hbm2ddl.import_files_sql_extractor=org.hibernate.tool.hbm2ddl.MultipleLinesSqlCommandExtractor
