最近我加入了一个新团队，这里的人使用 h2 进行存根服务。
我想知道是否可以使用网络界面显示该数据库的内容。在工作中，可以通过访问localhost:5080
我有一个使用 h2 数据库的项目，但是当我点击时我看不到 h2 Web 控制台localhost:5080
我也尝试过localhost:8082- 它也不起作用。
我的项目配置（成功运行）：
<bean id="wrappedDataSource" class="net.bull.javamelody.SpringDataSourceFactoryBean">
<property name="targetName" value="dataSource" />
</bean>
<bean id="wrappedDataSource" class="net.bull.javamelody.SpringDataSourceFactoryBean">
<property name="targetName" value="dataSource" />
</bean>
<bean class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" id="dataSource">
<property name="driverClassName" value="org.h2.Driver" />
<property name="url" value="jdbc:h2:~/test;MODE=PostgreSQL" />
<property name="username" value="sa" />
<property name="password" value="" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="wrappedDataSource"/>
<property name="configLocation">
<value>classpath:hibernate-test.cfg.xml</value>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.connection.charSet">UTF-8</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hbm2ddl.auto">create-drop</prop>
</props>
</property>
</bean>
<context:property-placeholder location="classpath:jdbc.properties"/>
我不知道如何访问 h2 Web 控制台。请帮忙。
P.S.
我只在中看到提到 h2.m2 folder
P.S.2
我注意到网络控制台可以通过http://localhost:8082/如果将配置中的 url 替换为：
<property name="url" value="jdbc:h2:tcp://localhost/~/test;MODE=PostgreSQL" />
But如果我已经开始 h2(in.m2文件夹查找h2jar 文件并双击）
如果我启动应用程序时 h2 未启动 - 我会看到以下错误：
java.lang.IllegalStateException: Failed to load ApplicationContext

如果我启动应用程序时 h2 未启动，我希望实现 h2 启动。
P.S.3
我尝试编写以下代码：
Server server = null;
try {
server = Server.createTcpServer("-tcpAllowOthers").start();
Class.forName("org.h2.Driver");
Connection conn = DriverManager.getConnection("jdbc:h2:tcp://localhost/~/test;MODE=PostgreSQL", "sa", "");
} catch (Exception e) {
LOG.error("Error while initialize", e);
}
我执行它并在尝试输入后localhost:9092在我的浏览器中。
此时正在下载文件。文件内包含以下内容：
Version mismatch, driver version is “0” but server version is “15”
我的 h2 版本 1.4.182
P.S.4
这段代码的工作原理：
public class H2Starter extends ContextLoaderListener {
private static final Logger LOG = LoggerFactory.getLogger(H2Starter.class);
@Override
public void contextInitialized(ServletContextEvent event) {
startH2();
super.contextInitialized(event);
}
private static void startH2() {
try {
Server.createTcpServer("-tcpAllowOthers").start();
Class.forName("org.h2.Driver");
DriverManager.getConnection("jdbc:h2:tcp://localhost/~/test;MODE=PostgreSQL;AUTO_SERVER=TRUE", "sa", "");
Server.createWebServer().start();
} catch (Exception e) {
LOG.error("cannot start H2 [{}]", e);
}
}
public static void main(String[] args) {
startH2();
}
}
但我只需要在混凝土弹簧配置文件处于活动状态时调用它（现在它始终有效）
