我是Spring编程的新手,目前正在努力使用Spring 3.1的基于Java的配置"我创建了以下配置类
@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("${jdbc.password}")
String password;
@Bean
public DataSource dataSource() {
System.out.println("Creating data Source.");
return new DriverManagerDataSource(url, username, password);
}
@Bean
public SessionFactory sessionFactory () throws Exception {
return new AnnotationSessionFactoryBuilder().setDataSource(dataSource()).setPackagesToScan("com.argusoft.loginmodule.domain").buildSessionFactory();
}
}
现在当我尝试运行项目时,我得到以下错误:
SEVERE: Exception while loading the app:java.lang.IllegalStateException: ContainerBase。addChild:开始:org.apache.catalina.LifecycleException:java.lang.IllegalArgumentException: javax.servlet.ServletException:java.lang.NoClassDefFoundError:org/springframework/core/env/EnvironmentCapable
卡住了,解决不了.....我在关注Spring Source Blog。
还请建议一些好的教程,其中Spring最新的基于Java的配置通过易于理解的示例进行解释…
提前致谢
从异常的角度看:
java.lang.NoClassDefFoundError: org/springframework/core/env/EnvironmentCapable
这个问题等于这个问题:Spring class EnvironmentCapable
所以正确答案可能是:
我认为需要使用3.1.0版本的包
由user810430给出:原始答案
you can puth configuration like this
inside application context:
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>/WEB-INF/configuration.properties</value>
</list>
</property>
</bean>
<import resource="db-config.xml" />
and
db-config.xml is:
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass">
<value>${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>
