项目的异常Spring Hibernate Jndi Tomcat

-1

我创建了我的项目，现在我尝试运行它，但我发现异常，这让我明白jdbc中的问题，也许在jndi连接中。项目的异常Spring Hibernate Jndi Tomcat

我pom.xml：

一些JNDI的设置我已经在web.xml中

<resource-ref> 
    <description>DB Connection</description> 
    <res-ref-name>jdbc/cms</res-ref-name> 
    <res-type>javax.sql.DataSource</res-type> 
    <res-auth>Container</res-auth> 
</resource-ref

我用最小的XML这么做是注释。我的调度员：

public class Dispatcher implements WebApplicationInitializer{ 

    @Override 
    public void onStartup(ServletContext servletContext) throws ServletException{ 
     AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext(); 
     appContext.register(ApplicationContext.class); 
     ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher", new DispatcherServlet(appContext)); 
     dispatcher.setLoadOnStartup(1); 
     dispatcher.addMapping("/"); 
    } 

}

和我的applicationContext

@Configuration 
@ComponentScan("com.myproject") 
@EnableTransactionManagement 
public class ApplicationContext{ 

    @Bean(name="viewResolver") 
    public InternalResourceViewResolver getViewResolver(){ 
     InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 
     viewResolver.setPrefix("/WEB-INF/jsp/"); 
     viewResolver.setSuffix(".jsp"); 
     return viewResolver;  
    } 

    @Bean(name="dataSource")  
    public DataSource getDataSource(){ 
     JndiDataSourceLookup dsLookup = new JndiDataSourceLookup(); 
     DataSource dataSource = dsLookup.getDataSource("jdbc/cms"); 
     return dataSource; 
    } 

    private Properties getHibernateProperties(){ 
     Properties properties = new Properties(); 
     properties.put("hibernate.show_sql","true"); 
     properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect"); 
     return properties; 
    } 

    @Autowired 
    @Bean(name="sessionFactory") 
    public SessionFactory getSessionFactory(DataSource dataSource){ 
     LocalSessionFactoryBuilder sessionBuilder = new LocalSessionFactoryBuilder(dataSource); 
     sessionBuilder.addAnnotatedClasses(com.myproject.User.class); 
     sessionBuilder.addProperties(getHibernateProperties()); 
     return sessionBuilder.buildSessionFactory(); 
    } 

    @Autowired 
    @Bean(name = "transactionManager") 
    public HibernateTransactionManager getTransactionManager(SessionFactory sessionFactory){ 
     HibernateTransactionManager transactionManager = new HibernateTransactionManager(sessionFactory); 
     return transactionManager; 
    } 

    @Autowired 
    @Bean(name="daoInterfaceImpl") 
    public DaoInterface getDaoInterfaceImpl(SessionFactory sessionFactory){ 
     return new DaoInterfaceImpl(sessionFactory); 
    } 

}

我也有控制器，模型类，查看...

，并在最后，我看到这些例外情况：

更新：

我以 '没有合适的驱动程序' 解决了这个问题。我解决它以这样的方式

<build> 
    <finalName>ApplicationAnnotations</finalName> 
    <plugins> 
     <plugin> 
     <groupId>org.apache.tomcat.maven</groupId> 
     <artifactId>tomcat7-maven-plugin</artifactId> 
     <configuration> 
      <url>http://localhost:8080/manager/text</url> 
      <server>tomcatserver</server> 
     </configuration> 
     <dependencies> 
      <dependency> 
      <groupId>mysql</groupId> 
      <artifactId>mysql-connector-java</artifactId> 
      <version>5.1.34</version> 
      <scope>compile</scope> 
      </dependency> 
     </dependencies> 
     </plugin> 
    </plugins> 
    </build>

而是 “没有合适的驱动程序” 我已经NullPointerException异常错误

问题在JNDI，因为当我更换

@Bean(name = "dataSource") 
    public DataSource getDataSource() { 
     BasicDataSource dataSource = new BasicDataSource(); 
     dataSource.setDriverClassName("com.mysql.jdbc.Driver"); 
     dataSource.setUrl("jdbc:mysql://localhost:3306/cms"); 
     dataSource.setUsername("root"); 
     dataSource.setPassword("admin"); 

     return dataSource; 
    }

代替

// @Bean(name="dataSource") 
    // public DataSource getDataSource(){ 
    // JndiDataSourceLookup dsLookup = new JndiDataSourceLookup(); 
    // DataSource dataSource = dsLookup.getDataSource("jdbc/cms"); 
    // return dataSource; 
    // }

项目开始正常工作。

在Tomcat的配置如何被定义的连接？从我所站的地方来看，异常情况表明，您的服务器类路径中没有JDBC驱动程序。 – 2015-01-09 18:35:46

更新，你可以看到 – alemale 2015-01-09 18:40:33

那你有你的服务器的类路径上'的mysql-xxxx.jar'（例如* $ {CATALINA_HOME}/lib目录*）？ – 2015-01-09 18:41:46

java.sql.SQLException: No suitable driver 
    java.sql.DriverManager.getDriver(DriverManager.java:278) 
    org.apache.tomcat.dbcp.dbcp.BasicDataSource.createConnectionFactory(BasicDataSource.java:1437)

如果数据源是由服务器配置定义和管理的，则JDBC驱动程序需要位于服务器的类路径中。

把你mysql-connector-java-5.1.34.jar在${CATALINA_HOME}/lib（有点脏的解决方案，你混淆了自定义的罐子正确的服务器JAR文件）。

如果您想要一个更漂亮的解决方案，请将JAR放置在${CATALINA_HOME}/lib/ext（要求篡改catalina.properties中的常见加载器位置）。

当获得从JNDI数据源，你并不需要包括JDBC驱动程序作为Web应用程序（即你可以从pom.xml删除）的依赖。

它没有帮助。 – alemale 2015-01-10 11:30:15

你还会得到同样的异常吗？因为如果你在服务器的类路径上有驱动程序，那么**不可能得到相同的异常。 – 2015-01-10 11:33:53

根据你的指令，我把mysql-connector-java-5.1.34.jar放在$ {CATALINA_HOME}/lib中，但它没有改变任何东西。之后，我在catalina.properties中编写了mysql-connector-java-5.1.34.jar，但是例外情况相同 – alemale 2015-01-10 11:51:10
