Windows에서 Debian으로 프로젝트를 내보낼 때의 MySQL 오류

Question

Tomcat 및 Mysql에서 Spring과 Hibernate로 실행되는 webapp가 있습니다. 내 컴퓨터에서 코드를 작성하는 데 사용합니다. Windows 7 기반 환경 : webapp이 정상적으로 작동합니다.

그런 다음 원격 데비안 서버에서 내 보내서 tomcat 및 mysql을 설치 한 다음 내 Windows mysql DB에서 Dump를 가져옵니다.

내가 MySQL의 콘솔 내 데이터베이스에 액세스 할 수없는 경우에도, 내 웹 애플리케이션은 나에게이 오류 포기하지 수 :

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.apache.commons.dbcp2.PoolableConnectionFactory.validateConnection(PoolableConnectionFactory.java:303)

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

그럼 내가 검색을 약 "hibernate.hbm2ddl.auto" 그래서 뭔가를 발견 내 conf에 추가 : prop.put ("hibernate.hbm2ddl.auto", "validate"); @Configuration @EnableWebSecurity AppSecurityConfig :

지금 : 여기

내 conf의 파일입니다 ...

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

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:475) 

그래서 내 응용 프로그램 내 데이터베이스에 액세스 할 수 보이지만 나는 이유를 이해 해달라고 public class AppSecurityConfig extends 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; 
} 
} 

MVCInitializer는 공용 클래스 MVCInitializer는 AbstractAnnotationConfigDispatcherServletInitializer를 확장 {

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

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

@Override 
protected String[] getServletMappings() { 
return new String[] { "/" }; 
} 
} 

ViewConfig

@EnableWebMvc 
@Configuration 
@ComponentScan({ "com.meltdown.*" }) 
@EnableTransactionManagement 
@Import({ AppSecurityConfig.class }) 
public class ViewConfig extends WebMvcConfigurerAdapter { 

    @Bean 
    public SessionFactory sessionFactory() { 
     LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource()); 
     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"); 
     prop.put("hibernate.hbm2ddl.auto", "validate"); 
     return prop; 
    } 

@Bean(name = "dataSource") 
public BasicDataSource dataSource() { 
    BasicDataSource ds = new BasicDataSource(); 
    ds.setDriverClassName("com.mysql.jdbc.Driver"); 
    ds.setUrl("jdbc:mysql://localhost:3306/meltdown2"); 
    ds.setUsername("root"); 
    ds.setPassword("myXP4NYYKF8"); 
    return ds; 
} 

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

@Override 
public void addResourceHandlers(ResourceHandlerRegistry registry) { 
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/bo_theme/**"); 
} 

@Bean 
public InternalResourceViewResolver viewResolver() { 
    InternalResourceViewResolver viewResolver 
    = new InternalResourceViewResolver(); 
    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; 
    } 
}

그 유일한 문제인지 잘 모르겠어요,하지만 난 당신의 로그에서이 오류 발견 :

Missing table: BARS을 .

Windows의 mysql 테이블 이름은 대소 문자를 구분하지 않는다는 것을 알고 있습니다. Linux/Unix 시스템에서는 대소 문자를 구분합니다. (필자는 Windows에서 코드를 개발할 때 어려운 방법을 배웠고 PC에서는 잘 작동했습니다. Linux 서버에 배포 할 때 작동하지 않습니다).

DB에 정의 된 테이블이 Windows에서 작동하는 바 또는 막대이지만 Linux/Unix에서는 작동하지 않는 동안 코드가 BARS 테이블 (모든 대문자)을 참조한다고 가정합니다.
