Spring的基于Java的配置对我不起作用

我是Spring编程的新手,目前正在努力使用Spring 3.1的Java Based Configuraion“我创建了以下Configuration类

@Configuration
@ImportResource("classpath:/resources/jdbc.properties")
public class AppConfig {

    @Autowired
    Environment env;
    private @Value("${jdbc.url}")
    String url;
    private @Value("${jdbc.username}")
    String username;
    private @Value("${jdbc.password}")
    String password;

    @Bean
    public DataSource dataSource() {
        System.out.println("Creating data Source.");
        return new DriverManagerDataSource(url, username, password);
    }

    @Bean
    public SessionFactory sessionFactory () throws Exception {
        return new AnnotationSessionFactoryBuilder().setDataSource(dataSource()).setPackagesToScan("com.argusoft.loginmodule.domain").buildSessionFactory();
    }
}

现在当我尝试运行项目时,我得到了以下错误。

输出

  

严重:加载应用时出现异常:   java.lang.IllegalStateException:ContainerBase.addChild:start:   org.apache.catalina.LifecycleException:   java.lang.IllegalArgumentException:javax.servlet.ServletException:   java.lang.NoClassDefFoundError:   组织/ springframework的/核心/ ENV / EnvironmentCapable

坚持下去,无法解决它......我正在关注Spring Source Blog

还请提供一些很好的教程,其中Spring的最新基于Java的配置通过易于理解的示例进行解释...

提前致谢,

2 个答案:

答案 0 :(得分:2)

从例外的角度来看:

java.lang.NoClassDefFoundError: org/springframework/core/env/EnvironmentCapable

这个问题等于问题:Spring class EnvironmentCapable

所以正确答案可能是:

  

我认为需要使用版本3.1.0 - in package   org.springframework.core-3.1.0.M2.jar这个类介绍。

you can puth configuration like this
inside application context:
    <bean id="propertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>/WEB-INF/configuration.properties</value>
            </list>
        </property>
    </bean>

<import resource="db-config.xml" />

and   
db-config.xml is:
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
        destroy-method="close">

        <property name="driverClass">
            <value>${jdbc.driver.className}</value>
        </property>
        <property name="jdbcUrl">
            <value>${jdbc.url}</value>
        </property>
        <property name="user">
            <value>${jdbc.username}</value>
        </property>
        <property name="password">
            <value>${jdbc.password}</value>
        </property>
    </bean>
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" autowire="byName">
        <property name="dataSource">
        <ref bean="dataSource" />
        </property>
        <property name="packagesToScan" value="com.huawei.sa.album" />
        <property name="hibernateProperties">
                 <props>
                                <prop key="hibernate.dialect">${jdbc.hibernate.dialect}</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <!-- uncomment this for first time run-->
                <prop key="hibernate.show_sql">false</prop>
            </props>
        </property>

    </bean>


    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>

       <tx:annotation-driven />

</beans>
