问题描述
我有hibernate.cfg.xml文件。
< session-factory>
< property name =connection.driver_class> com.mysql.jdbc.Driver< / property>
< property name =connection.url>< / property>
< property name =connection.username>< / property>
< property name =connection.password>< / property>
< property name =connection.pool_size> 1< / property>
.....................
这是文件中最有趣的部分。
现在我必须设置缺失值:网址,用户名,密码。
我想这样做:
public static void SetSessionFactory(){
try {
AnnotationConfiguration conf = new AnnotationConfiguration()。configure();
//<! - 数据库连接设置 - >
conf.setProperty(connection.url,URL);
conf.setProperty(connection.username,USERNAME);
conf.setProperty(connection.password,PASSWORD);
SESSION_FACTORY = conf.buildSessionFactory();
} catch(Throwable ex){
//记录异常!
抛出新的ExceptionInInitializerError(ex);
$ / code>
但它只是从hibernate.cfg加载我的配置。 xm并且不要更改任何属性......
url,username,passoword - 是命令行参数,所以我必须在运行时设置它们。 $ b
解决方案 试着在这里调用 conf.configure();
b属性可能需要有hibernate前缀,如hibernate.connection.username
希望它有帮助。
I have hibernate.cfg.xml file.
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url"></property>
<property name="connection.username"></property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
.....................
This is the most interesting part of file.Now i must set missing values: url, username, password.I'm trying to do in such way:
public static void SetSessionFactory() {
try {
AnnotationConfiguration conf = new AnnotationConfiguration().configure();
// <!-- Database connection settings -->
conf.setProperty("connection.url", URL);
conf.setProperty("connection.username", USERNAME);
conf.setProperty("connection.password", PASSWORD);
SESSION_FACTORY = conf.buildSessionFactory();
} catch (Throwable ex) {
// Log exception!
throw new ExceptionInInitializerError(ex);
}
}
But it just loads my configuration from hibernate.cfg.xm and do not changing any property...
url, username, passoword - are command-line arguments so i must set them on runtime.
解决方案 Try to call conf.configure();
here.
And properties may need to have hibernate prefix like "hibernate.connection.username"
Hope it helps.
