Question

我试图在Eclipse上启动我的Tomcat服务器，但它始终挂在日志上的这一行

14:44:52.467 INFO  o.s.o.j.LocalContainerEntityManagerFactoryBean - Building JPA container EntityManagerFactory for persistence unit 'default'

我甚至将超时设置为999秒仍然会超时。

我正在尝试使用Maven启动Spring Web应用程序。

所以我可以查明挂起的原因，Building JPA container EntityManagerFactory for persistence unit 'default'期间发生了什么？为什么它挂在那里？

这是我在Tomcat中的context.xml

<Resource name="jdbc/default" auth="Container" type="javax.sql.DataSource"
    maxActive="-1" maxIdle="-1" maxWait="-1" autoReconnect="true"
    username="example" password="example" driverClassName="com.mysql.jdbc.Driver"
    spring.datasource.testOnBorrow="true"
    spring.datasource.validationQuery="SELECT 1"
    url="jdbc:mysql://example:1106/example" />

<Resource name="jdbc/default_gathering" auth="Container" type="javax.sql.DataSource"
    maxActive="-1" maxIdle="-1" maxWait="-1" autoReconnect="true"
    username="example" password="example" driverClassName="com.mysql.jdbc.Driver"
    spring.datasource.testOnBorrow="true"
    spring.datasource.validationQuery="SELECT 1"
    url="jdbc:mysql://example:1106/admin" />

的persistence.xml
