最近在学习SpringMvc开发，有一个提问困扰了很久，就是在Eclipse启动Tomcat需要很长时间，大概要1分多钟。

Spring配置：
@Bean
public DataSource dataSource(){
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getRequiredProperty("jdbc.driverClassName"));
dataSource.setUrl(env.getRequiredProperty("jdbc.url"));
dataSource.setUsername(env.getRequiredProperty("jdbc.username"));
dataSource.setPassword(env.getRequiredProperty("jdbc.password"));
dataSource.setInitialSize(env.getRequiredProperty("jdbc.initialSize", Integer.class));
dataSource.setMaxIdle(env.getRequiredProperty("jdbc.maxIdle", Integer.class));
return dataSource;
} @Bean
public LocalSessionFactoryBean sessionFactory(DataSource dataSource){
LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();
factoryBean.setDataSource(dataSource);
factoryBean.setMappingResources(new String[]{
"com/caihao/hibernate/caihao.hbm.xml"
});
Properties props = new Properties();
props.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
props.setProperty("hibernate.show_sql", "true");
props.setProperty("hibernate.jdbc.fetch_size", "50");
factoryBean.setHibernateProperties(props);
return factoryBean;
}
解决方法添加：
props.setProperty("hibernate.temp.use_jdbc_metadata_defaults", "false");
