H2 不保存价值，不抛出任何异常
Posted
技术标签:
【中文标题】H2 不保存价值，不抛出任何异常【英文标题】：H2 not saving value and not throwing any exceptions 【发布时间】：2012-09-04 12:11:14 【问题描述】：我开始使用 h2 数据库。
我正在使用以下代码在数据库中保存一个值 -
public class MyDao extends NamedParameterJdbcDaoSupport
public void save()
System.out.println("Saving..");
getNamedParameterJdbcTemplate().update(
"insert into mytable values(:time)",
new MapSqlParameterSource("time", new Date()));
System.out.println("Saved..");
弹簧配置-
<bean id="dataSource" class="org.h2.jdbcx.JdbcConnectionPool"
destroy-method="dispose">
<constructor-arg>
<bean class="org.h2.jdbcx.JdbcDataSource">
<property name="URL" value="jdbc:h2:tcp://localhost:8082/test/" />
<property name="user" value="sa" />
<property name="password" value="" />
</bean>
</constructor-arg>
</bean>
代码打印Saving..，然后从不打印Saved..。它在更新语句处冻结。
没有抛出异常。这是为什么呢？

【问题讨论】：
你能得到一个完整的线程转储并发布吗？要获取进程 ID，请在命令行上运行jps -l，然后运行 jstack -l <pid> 以获取完整的线程转储。
@KshitizSharma 服务器端怎么样，你也可以发布完整的线程转储吗？实际上我会先检查H2服务器版本是否与客户端相同（理论上应该没有问题，但过去有一些兼容性）。
@ThomasMueller 也这样做了。客户端和服务器都运行 1.3.168
@ThomasMueller 如果我将数据库 url 字符串更改为 localhost 而不是 localhost:8082，问题就会消失。我不明白为什么会这样。它不应该在端口 8082 上运行吗？
@KshitizSharma Web 服务器的默认端口是 8082，但这是错误的服务器。您不想连接到 Web 服务器，而是想连接到 TCP 服务器。默认端口是 9092。
【参考方案1】：
问题出在 jdbc url 中，它应该包含 localhost:9092 而不是 localhost:8082。
从上面的评论中引用 Thomas Mueller -
Web 服务器的默认端口是 8082，但这是错误的 服务器。你不想连接到网络服务器，你想 连接到 TCP 服务器。那里的默认端口是 9092。
