当我在tomcat中重新部署我的应用程序时,我遇到以下问题:
The web application [] created a ThreadLocal with key of type
[java.lang.ThreadLocal] (value [java.lang.ThreadLocal@10d16b])
and a value of type [com.sun.xml.bind.v2.runtime.property.SingleElementLeafProperty]
(value [com.sun.xml.bind.v2.runtime.property.SingleElementLeafProperty@1a183d2]) but
failed to remove it when the web application was stopped.
This is very likely to create a memory leak.
另外,我在我的应用程序中使用ehcache.这似乎也导致以下异常.
SEVERE: The web application [] created a ThreadLocal with key of type [null]
(value [com.sun.xml.bind.v2.ClassFactory$1@24cdc7]) and a value of type [java
.util.WeakHashMap...
ehcache似乎创建了一个弱哈希映射,我得到的消息是,这很可能会造成内存泄漏.
我在网上搜索并发现了这个, http://jira.pentaho.com/browse/PRD-3616但是我没有这样的服务器访问权限.
如果这些警告有任何功能影响或是否可以忽略,请告诉我？我在tomcat管理器中使用了"查找内存泄漏"选项,它说"没有发现内存泄漏"
我在Tomcat 7中有一个Web应用程序.
当我关闭Tomcat时,我看到了这些警告(但并非总是如此)
SEVERE: The web application [/MyApplication] created a ThreadLocal
with key of type
[org.apache.xml.security.algorithms.MessageDigestAlgorithm$1] (value
[org.apache.xml.security.algorithms.MessageDigestAlgorithm$1@2e2c2e2c])
and a value of type [java.util.HashMap] (value
[{http://www.w3.org/2000/09/xmldsig#sha1=MESSAGE DIGEST SHA-1}]) but
failed to remove it when the web application was stopped. Threads are
going to be renewed over time to try and avoid a probable memory leak.
