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。
启动日志：

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");
