Question

我使用以下配置启动SessionFactory：

    <?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!-- Concrete services -->

    <bean id="userService" class="org.blog.service.UserService" parent="sessionService" />

    <!-- Hibernate base -->

    <bean id="sessionService" abstract="true" class="org.blog.service.SessionService">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses"> 
            <list> 
                <value>org.blog.domain.User</value> 
            </list> 
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </bean>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/website"/>
        <property name="username" value="root"/>
        <property name="password" value="enter"/>
    </bean>

</beans>

但是，运行时会弹出以下错误：

我认为我的图书馆出了问题。

目前我正在使用这些：

公地集合-3.1.jar
公地dbcp.jar
公地logging.jar
公地pool.jar
DOM4J-1.6.1.jar
EJB3-persistence.jar
hibernate3.jar（3.5包含注释）
javaee.jar
了Javassist-3.9.0.GA.jar
jstl.jar jta-1.1.jar
MySQL的连接器的Java-3.1.12-bin.jar
org.springframework.asm-3.0.0.RC1.jar
org.springframework.beans-3.0.0.RC1.jar
org.springframework.context-3.0.0.RC1.jar
org.springframework.context.support-3.0.0.RC1.jar
org.springframework.core-3.0.0.RC1.jar
org.springframework.expression-3.0.0.RC1.jar
org.springframework.jdbc-3.0.0.RC1.jar
org.springframework.orm-3.0.0.RC1.jar
org.springframework.transaction-3.0.0.RC1.jar
org.springframework.web-3.0.0.RC1.jar
org.springframework.web.servlet-3.0.0.RC1.jar
SLF4J-API-1.5.8.jar
standard.jar

任何人都可以确定导致我错误的原因吗？我的源代码分发在http://code.google.com/p/jeesh-blog/

Answer 1

您正在使用SLF4J，但只在类路径中使用SLF4j-API。 您还需要SLF4J 的实现，例如SLF4j-NOP或SLF4j-Simplelogger。

您可以通过实现一个简单的测试用例来初始化Spring ApplicationContext，然后用Java 6 运行它来查看无法找到哪个Class：

public class AppCtxTest {
    @Test
    public void testApplicationContext() throws Exception {
        FileSystemXmlApplicationContext ctx = new FileSystemXmlApplicationContext(
                "app/WEB-INF/services.xml");
        ctx.close();
    }
}

输出将显示缺少的内容;

org.springframework.beans.factory.BeanCreationException:
    Error creating bean with name 'userService' defined in file [C:\Users\mhaller\workspace\Blog\app\WEB-INF\services.xml]:
    Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory';
    nested exception is ...
Caused by: org.springframework.beans.factory.BeanCreationException:
    Error creating bean with name 'sessionFactory' defined in file [C:\Users\mhaller\workspace\Blog\app\WEB-INF\services.xml]:
    Invocation of init method failed;
    nested exception is java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder
Caused by: java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder
Caused by: java.lang.ClassNotFoundException: org.slf4j.impl.StaticLoggerBinder

确实缺少一些依赖项：

SLFJ4j实施（slf4j-xxx.jar）
Java Persistence API（jpa.jar）：javax.persistence.ElementCollection

Answer 2

hibernate javax / persistence / ElementCollection

* JPA 2.0作为Java EE 6发行版（Sept09）的一部分发布

* JPA 2.0参考实现将是EclipseLink项目（开源TopLink）随WLS，Glassfish，Spring或独立运输 http：/ www.eclipse.org/eclipselink
