无法使用Spring + GORM + Gradle设置NamingStrategy

Question

我们将使用Spring和GORM和Gradle启动一个新项目。我已经能够为hibernate配置大多数属性，但是到目前为止我还没有找到正确的方法来设置命名策略。

尝试

我尝试在application.properties中设置各种属性并添加文件hibernate.properties.我们使用的是自动配置，我看到在HibernateGormAutoConfiguration.中发现并添加了道具

我还做了一些尝试，创建实体管理器和会话工厂bean，但没有成功。

示例来自application.properties (尝试所有排列)：

spring.hibernate.hbm2ddl.auto=none # this works!!
# from now on none works
# I tried all permutations with combinations of
# *.hibernate[.ejb].* and *.naming_strategy/naming-strategy
spring.hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
spring.hibernate.ejb.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
spring.jpa.hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
spring.properties.hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
spring.jpa.properties.hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
spring.gorm.hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
spring.gorm.properties.hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
gorm.hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy

来自src/main/resources/hibernate.properties:的示例

hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy
hibernate.ejb.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy

启动应用程序并尝试加载实体时的日志记录和堆栈跟踪：

2014-11-03 10:12:04.381  INFO 81729 --- [           main] org.hibernate.cfg.Environment            : HHH000205: Loaded properties from ... 
resource hibernate.properties: {hibernate.ejb.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy, hibernate.namingStrategy=org.hibernate.cfg.DefaultNamingStrategy, hibernate.bytecode.use_reflection_optimizer=false}

    java.sql.SQLException: Invalid column name 'origin_marking'.
    at net.sourceforge.jtds.jdbc.SQLDiagnostic.addDiagnostic(SQLDiagnostic.java:372)

代码示例

不幸的是，根据每个字段重写字段名并不是一个可行的解决方案：

static mapping = {
    columns {
        originMarking column: 'originMarking'
    }
}

构建文件的摘录如下所示：

.. // main build file
buildscript {
    repositories {
        jcenter()
        maven { url "http://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.0.M2")
        classpath 'org.springframework:springloaded:1.2.0.RELEASE'
    }
}
..
apply plugin: 'spring-boot'
..
.. // domain build file
jar.baseName = 'domain'
dependencies {
    compile "org.grails:gorm-hibernate4-spring-boot:1.1.0.RELEASE",
            "joda-time:joda-time:2.5",
            'org.jadira.usertype:usertype.jodatime:2.0.1',
            "commons-dbcp:commons-dbcp:1.4",
            "net.sourceforge.jtds:jtds:1.2.7"
    runtime "com.h2database:h2"
}
..
.. // api build file
apply plugin: 'spring-boot'
jar.baseName = 'api'
dependencies {
    compile project(':domain')
    compile "org.springframework.boot:spring-boot-starter-jersey"
    ..
}  

任何帮助都将不胜感激！！

Answer 1

Grails确实使用了spring.hibernate.naming_strategy设置，但它的使用方式并不像您所期望的那样，而且它没有触及默认的命名策略。我不知道这是什么原因。您可能想通过提出问题与Grails团队讨论这个问题。

同时，可以通过在configureNamingStrategy上调用AbstractGrailsDomainBinder来编程地配置默认命名策略。例如：

@EnableAutoConfiguration
class Application {
    static void main(String[] args) {
        AbstractGrailsDomainBinder.configureNamingStrategy('DEFAULT', DefaultNamingStrategy)
        SpringApplication.run Application, args
    }
}
