Java Spring和x2B的特定环境配置；Hibernate应用程序

我正在努力为hibernate使用不同的.properties文件来配置我的Spring应用程序。我的计划是创建一个maven属性，该属性将反映我希望通过概要文件选择的环境。然后在我的hibernate.cfg.xml上加载属性变量

文件：hibernate.cfg.xml：

.... <property name="hbm2ddl.auto">${hibernate.hbm2ddl.auto}</property>  ...

文件：spring-context.xml:

... <context:property-placeholder location="classpath*:*persistence-${envTarget}.properties" /> ...

。。。

我这里缺少什么？

hibernate.cfg.xml不是由Spring管理的

试图使用

propertyplaceholderconfigure

（或其替代

propertysourcesplaceplaceconfigurer

）对其进行筛选是无用的

您可以使用Maven资源筛选支持：

<profiles>
    <profile>
        <id>dev</id>
        <properties>
            <hibernate.hbm2ddl.auto>dev</hibernate.hbm2ddl.auto>
        </properties>
    </profile>

    <profile>
        <id>prod</id>
        <properties>
            <hibernate.hbm2ddl.auto>validate</hibernate.hbm2ddl.auto>
        </properties>
    </profile>
</profiles>

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

真的

您还可以将其与Spring概要文件支持结合使用（假设您愿意在构建期间将Spring概要文件名称传递给Maven，而不仅仅是使用运行时，如果您从Maven运行Spring概要文件相关的测试，您无论如何都会这样做）：

spring.profiles.active

我是通过以下方式实现的：

将所有环境的公共属性保存在

hibernate.cfg.xml

文件中，如下所示

 <hibernate-configuration>
        <session-factory>

            <!-- JDBC connection pool (use the built-in) -->
            <property name="connection.pool_size">1</property>

            <!-- SQL dialect -->
            <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

            <!-- Enable Hibernate's automatic session context management -->
            <property name="current_session_context_class">thread</property>


            <!-- Echo all executed SQL to stdout -->
            <property name="show_sql">true</property>

            <!-- Drop and re-create the database schema on startup -->
            <property name="hbm2ddl.auto">update</property>

          <!-- DB mapping if any -->    
            <mapping class='classname'></mapping>


        </session-factory>
    </hibernate-configuration>

下面是放置在资源文件夹中的

local.properties

文件

#hibernate properties
connection.url=jdbc:mysql://localhost:3306/rivigo
connection.username=root
connection.password=root

希望有帮助

工作得很有魅力！非常感谢。现在，是否可以仅为一个特定类更改“hibernate.hbm2ddl.auto”属性？是否可以在配置文件之间共享属性？如果要在两个配置文件之间共享属性，最好在pom文件的

properties

部分声明它们。我不明白你说的更改特定类的属性是什么意思。

 <hibernate-configuration>
        <session-factory>

            <!-- JDBC connection pool (use the built-in) -->
            <property name="connection.pool_size">1</property>

            <!-- SQL dialect -->
            <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

            <!-- Enable Hibernate's automatic session context management -->
            <property name="current_session_context_class">thread</property>


            <!-- Echo all executed SQL to stdout -->
            <property name="show_sql">true</property>

            <!-- Drop and re-create the database schema on startup -->
            <property name="hbm2ddl.auto">update</property>

          <!-- DB mapping if any -->    
            <mapping class='classname'></mapping>


        </session-factory>
    </hibernate-configuration>
