提问by SJS

I Moving from Spring MVC XML files to javaconfig. I am really at a lost with my database XML file. I don't know how to get Hibernate4 working and my JBoss JNDI Datasource working. Can someone please tell me how to make the javaconfig class work like this XML..

我从 Spring MVC XML 文件迁移到 javaconfig。我真的对我的数据库 XML 文件不知所措。我不知道如何让 Hibernate4 工作和我的 JBoss JNDI 数据源工作。有人可以告诉我如何使 javaconfig 类像这个 XML 一样工作..

Here is my database.xml:

I think the parts I am missing are the following but please overcheck my class

我认为我缺少的部分如下，但请检查我的课程

<context:property-placeholder location="classpath:app.properties" />

    <context:component-scan base-package="org.uftwf" />

    <tx:annotation-driven transaction-manager="hibernateTransactionManager" />

    <jee:jndi-lookup id="dataSource" jndi-name="java:jboss/datasources/mySQLDB"
        expected-type="javax.sql.DataSource" />

For

为了

<tx:annotation-driven transaction-manager="hibernateTransactionManager" />

annotate your Configuration class, WebMVCConfig, with

注释您的配置类, WebMVCConfig, 与

@EnableTransactionManagement

For

为了

<context:component-scan base-package="org.uftwf" />

Add the package String to your @ComponentScanfield basePackages

将包字符串添加到您的@ComponentScan字段basePackages

For

为了

<context:property-placeholder location="classpath:app.properties" />

annotate your Configuration class with

注释您的配置类

@PropertySource(value = "classpath:app.properties")

and make your PropertyPlaceholderConfigurer@Beanmethod static.

并制定您的PropertyPlaceholderConfigurer@Bean方法static。

For

为了

 <jee:jndi-lookup id="dataSource" jndi-name="java:jboss/datasources/mySQLDB"
    expected-type="javax.sql.DataSource" />

I think you can do

我认为你可以做到

@Bean
public DataSource dataSource() throws Exception {
    Context ctx = new InitialContext();
    return (DataSource) ctx.lookup("java:jboss/datasources/mySQLDB");
}

Instead of autowiring your session factory, just call your @Beanmethod

而不是自动装配您的会话工厂，只需调用您的@Bean方法

@Bean
public HibernateTransactionManager transactionManager()
{
    HibernateTransactionManager htm = new HibernateTransactionManager();
    htm.setSessionFactory(sessionFactory());
    return htm;
}
