，這是我的春天LDAP設置

<property name="baseEnvironmentProperties"> 
    <props> 
     <prop key="com.sun.jndi.ldap.connect.pool">true</prop> 
     <prop key="com.sun.jndi.ldap.connect.pool.initsize">1</prop> 
     <prop key="com.sun.jndi.ldap.connect.pool.maxsize">1</prop> 
     <prop key="com.sun.jndi.ldap.connect.pool.prefsize">1</prop> 
    <prop key="com.sun.jndi.ldap.connect.pool.timeout">300000</prop> 
    </props> 
</property> 

任何意見，爲什麼這個事業內存不足？我的池大小隻有1？

Answer 1

我懷疑它與LDAP或池大小有什麼關係。燙髮可能會被填滿。我會打開visualvm並觀察應用程序啓動時發生的情況，看看是否屬於這種情況。

我也會檢查Tomcat日誌，看看是否有更多，更好的信息比這個堆棧跟蹤。
