将项目从Windows导出到Debian时发生的错误

Question

我有一个运行在Tomcat和Mysql上的Spring和Hibernate的webapp。 我用我的电脑上的代码：基于Windows 7的环境：webapp工作正常。

然后我试图将它导出到远程的debian服务器上，所以我安装了tomcat和mysql，然后从我的Windows mysql数据库中导入了一个Dump。

即使我可以访问我的数据库MySQL控制台，我的web应用程序不能给我这个错误：

20:35:03,020 DEBUG LogicalConnectionImpl:226 - Obtaining JDBC connection 
20:35:03,021 DEBUG PoolableConnectionFactory:292 - Failed to validate a poolable connection 
java.sql.SQLException: isValid() returned false 
    at org.apache.commons.dbcp2.PoolableConnection.validate(PoolableConnection.java:228)

    at org.hibernate.engine.jdbc.connections.internal.DatasourceConnectionProviderImpl.getConnection(DatasourceConnectionProviderImpl.java:139) 

然后我搜索，发现一些有关“hibernate.hbm2ddl.auto”所以我添加到我的conf： prop.put（“hibernate.hbm2ddl.auto”，“验证”）;

现在：

20:53:24,701 ERROR ContextLoader:331 - Context initialization failed

因此，看起来，我的应用程序不能访问我的数据库，但我不明白为什么...

这里是我的conf文件： AppSecurityConfig @Configuration @EnableWebSecurity 公共类AppSecurityConfig扩展了WebSecurityConfigurerAdapter {

@Autowired 
@Qualifier("userDetailsService") 
UserDetailsService userDetailsService; 

@Autowired 
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 
    auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder()); 
} 

@Override 
protected void configure(HttpSecurity http) throws Exception { 
    http 
    .csrf().disable() 
    .authorizeRequests() 
    .antMatchers("/bo/**").access("hasRole('ROLE_ADMIN')") 
    .antMatchers("/bo/bars**").access("hasRole('ROLE_SUPERADMIN')") 
    .and().formLogin(); 
} 

@Override 
public void configure(WebSecurity web) throws Exception { 
    web 
    .ignoring() 
    .antMatchers("/resources/**"); 
} 

@Bean 
public PasswordEncoder passwordEncoder(){ 
    PasswordEncoder encoder = new BCryptPasswordEncoder(); 
    return encoder; 
} 
} 

MVCInitializer 公共类MVCInitializer扩展AbstractAnnotationConfigDispatcherServletInitializer {

@Override 
protected Class<?>[] getRootConfigClasses() { 
return new Class[] { ViewConfig.class }; 
} 

@Override 
protected Class<?>[] getServletConfigClasses() { 
return null; 
} 

@Override

return new String[] { "/" }; 
} 
} 

ViewConfig

@EnableWebMvc 
@Configuration

     builder.scanPackages("com.meltdown").addProperties(getHibernateProperties()); 
     return builder.buildSessionFactory(); 
    } 

    private Properties getHibernateProperties() { 
     Properties prop = new Properties(); 
     prop.put("hibernate.format_sql", "true"); 
     prop.put("hibernate.show_sql", "true"); 
     prop.put("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");

    ds.setUsername("root"); 
    ds.setPassword("myXP4NYYKF8"); 
    return ds; 
} 

//Create a transaction manager 
@Bean 
public HibernateTransactionManager txManager() { 
    return new HibernateTransactionManager(sessionFactory());

    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/bo_theme/**");

    viewResolver.setViewClass(JstlView.class); 
    viewResolver.setPrefix("/WEB-INF/pages/"); 
    viewResolver.setSuffix(".jsp"); 
    return viewResolver; 
} 

@Bean 
    public MultipartResolver multipartResolver() { 
    CommonsMultipartResolver resolver = new CommonsMultipartResolver(); 
    resolver.setMaxUploadSize(1000000); 
    return resolver; 
    } 
}

我不知道如果这是唯一的问题，但我注意到这个错误日志中的：

Missing table: BARS 。我知道Windows中的mysql表名在默认情况下不区分大小写，而在Linux/Unix系统中它们区分大小写（当我在Windows中开发代码并在我的PC上正常工作时，在部署在我们的Linux服务器上时不起作用）。

我假设你的代码引用表BARS（所有大写字母），而在数据库中定义的表是酒吧或酒吧，它适用于Windows，但不适用于Linux/Unix。
