項目的異常Spring Hibernate Jndi Tomcat

-1

我創建了我的項目，現在我嘗試運行它，但我發現異常，這讓我明白jdbc中的問題，也許在jndi連接中。項目的異常Spring Hibernate Jndi Tomcat

我pom.xml：

一些JNDI的設置我已經在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這麼做是註釋。我的調度員：

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，模型類，查看...

，並在最後，我看到這些例外情況：

更新：

我以 '沒有合適的驅動程序' 解決了這個問題。我解決它以這樣的方式

<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「沒有合適的驅動程序」我已經NullPointerException異常錯誤

問題在JNDI，因爲當我更換

@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; 
    // }

項目開始正常工作。

在Tomcat的配置如何被定義的連接？從我所站的地方來看，異常情況表明，您的服務器類路徑中沒有JDBC驅動程序。 – 2015-01-09 18:35:46

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

那你有你的服務器的類路徑上'的mysql-xxxx.jar'（例如* $ {CATALINA_HOME}/lib目錄*）？ – 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)

如果數據源是由服務器配置定義和管理的，則JDBC驅動程序需要位於服務器的類路徑中。

把你mysql-connector-java-5.1.34.jar在${CATALINA_HOME}/lib（有點髒的解決方案，你混淆了自定義的罐子正確的服務器JAR文件）。

如果您想要一個更漂亮的解決方案，請將JAR放置在${CATALINA_HOME}/lib/ext（要求篡改catalina.properties中的常見加載器位置）。

當獲得從JNDI數據源，你並不需要包括JDBC驅動程序作爲Web應用程序（即你可以從pom.xml刪除）的依賴。

它沒有幫助。 – alemale 2015-01-10 11:30:15

你還會得到同樣的異常嗎？因爲如果你在服務器的類路徑上有驅動程序，那麼**不可能得到相同的異常。 – 2015-01-10 11:33:53

根據你的指令，我把mysql-connector-java-5.1.34.jar放在$ {CATALINA_HOME}/lib中，但它沒有改變任何東西。之後，我在catalina.properties中編寫了mysql-connector-java-5.1.34.jar，但是例外情況相同 – alemale 2015-01-10 11:51:10
