如何配置spring多个配置文件数据库javaconfig

Question

如何使用带有配置文件的Spring MVC启动项目，与数据库建立多个连接..并使用gradle运行测试？

前段时间我正在尝试进行这些设置而我没有得到我做错的事情？ （对不起我的英文我正在使用谷歌翻译。）​​

以下是我的设置

开发设置

db.driver=org.postgresql.Driver
db.url=jdbc:postgresql://localhost:5432/nextinfoerp
db.username=myuser
db.password=mypass

#Hibernate Configuration:
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
hibernate.show_sql=true
hibernate.format_sql =true
entitymanager.packages.to.scan=br.com.nextinfo.erp

测试设置

#Test properties:
db.driver=org.postgresql.Driver
db.url=jdbc:postgresql://localhost:5432/nextinfoerptestdb
db.username=myuser
db.password=mypass

#Hibernate Configuration:
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
hibernate.show_sql=true
hibernate.format_sql =true
entitymanager.packages.to.scan=br.com.nextinfo.erp

Gradle设置

 apply plugin: 'war'
 apply plugin: 'eclipse-wtp'
 apply plugin: 'jetty'

我正在使用spring-data

错误 Servlet调度程序的Servlet.init（）引发了异常

如果我删除正常使用注释inicializer函数的注释配置文件和类， 我该如何解决这个问题？

Answer 1

我通过移动数据库配置类以及根设置

来解决问题

 @Override
 protected Class<?>[] getRootConfigClasses() {
 return new Class[] {ThymeleafConfig.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]     {ThymeleafConfig.class,ProdProfileDatabase.class,DevProfileDatabase.class,TestPr   ofileDatabase.class};
}

我做了这次交流

@Override
protected Class<?>[] getRootConfigClasses() {
  return new Class[] {ProdProfileDatabase.class,DevProfileDatabase.class,TestPr ofileDatabase.class};
  }

@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]    {ThymeleafConfig.class};
}
