我们将我们的网站作为iframe集成到另一个在不同域上运行的网站.似乎我们无法设置cookie.以前有人遇到过这个问题吗？有任何想法吗？

我们偶尔会遇到例外情况,例如:

com.google.gwt.user.client.rpc.SerializationException:类型"xxx"无法分配给"com.google.gwt.user.client.rpc.IsSerializable",并且没有自定义字段序列化程序.出于安全考虑,此类型不会序列化:com.google.gwt.user.client.rpc.impl中的com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serialize(ServerSerializationStreamWriter.java:610)中的instance = xxx .AbstractSerializationStreamWriter.writeObject(AbstractSerializationStreamWriter.java:129)维持在com.google.gwt.user.server com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter $ ValueWriter $ 8.write(ServerSerializationStreamWriter.java:152). rpc.impl.ServerSerializationStreamWriter.serializeValue(ServerSerializationStreamWriter.java:534)位于com.google.gwt.user.server.rpc.RPC.encodeResponse(RPC.java:609)位于com.google.gwt.user.server.rpc.RPC.encodeResponseForSuccess(RPC.java:467)com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.的java:564)在com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:188)在de.softconex.travicemanager.server.TraviceManagerServiceImpl.processCall(TraviceManagerServiceImpl.java:615)在com.google .gwt.user.server.rpc.RemoteServiceServlet.processPost(RemoteServiceServlet.java:224)在com.google.gwt.user.server.rpc.AbstractRemoteServiceServlet.doPost(AbstractRemoteServiceServlet.java:62)在javax.servlet.http.HttpServlet .service(HttpServlet.java:710)位于org.apache.catalina.core.ApplicationFilterChain的javax.servlet.http.HttpServlet.service(HttpServlet.java:803).internalDoFilter(ApplicationFilterChain.java:290)在org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)在org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)在组织位于org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)的.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235)org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve) .java:230)在org.jboss的org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175)org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179). org.apache.catalina上的web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84).core.StandardHostValve.invoke(StandardHostValve.java:127)在org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)在org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve. java:157)org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262)at org.apache.coyote.ajp .AjpAprProcessor.process(AjpAprProcessor.java:419)在org.apache.coyote.ajp.AjpAprProtocol $ AjpConnectionHandler.process(AjpAprProtocol.java:378)在org.apache.tomcat.util.net.AprEndpoint $ Worker.run(AprEndpoint .java:1508)在java.lang.Thread.run(Thread.java:619)调用(ErrorReportValve.java:102)在org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157)在org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)在org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262)在org.apache.coyote.ajp.AjpAprProcessor.process(AjpAprProcessor.java:419)在org.apache.coyote.ajp.AjpAprProtocol $ AjpConnectionHandler .process(AjpAprProtocol.java:378)atg.apache.tomcat.util.net.AprEndpoint $ Worker.run(AprEndpoint.java:1508)at java.lang.Thread.run(Thread.java:619)调用(ErrorReportValve.java:102)在org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157)在org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)在org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262)在org.apache.coyote.ajp.AjpAprProcessor.process(AjpAprProcessor.java:419)在org.apache.coyote.ajp.AjpAprProtocol $ AjpConnectionHandler .process(AjpAprProtocol.java:378)atg.apache.tomcat.util.net.AprEndpoint $ Worker.run(AprEndpoint.java:1508)at java.lang.Thread.run(Thread.java:619)connector.CoyoteAdapter.service(CoyoteAdapter.java:262)在org.apache.coyote.ajp.AjpAprProcessor.process(AjpAprProcessor.java:419)在org.apache.coyote.ajp.AjpAprProtocol $ AjpConnectionHandler.process(AjpAprProtocol.java: 378)atg.apache.tomcat.util.net.AprEndpoint $ Worker.run(AprEndpoint.java:1508)at java.lang.Thread.run(Thread.java:619)connector.CoyoteAdapter.service(CoyoteAdapter.java:262)在org.apache.coyote.ajp.AjpAprProcessor.process(AjpAprProcessor.java:419)在org.apache.coyote.ajp.AjpAprProtocol $ AjpConnectionHandler.process(AjpAprProtocol.java: 378)atg.apache.tomcat.util.net.AprEndpoint $ Worker.run(AprEndpoint.java:1508)at java.lang.Thread.run(Thread.java:619)

该应用程序通常正常运行.指示的类实现Serializable(整个对象图).

到目前为止,唯一的模式/观察是:

• 我们似乎只有在iframe中使用应用程序时才会遇到问题

• 当部署了新版本的应用程序时,似乎会出现问题

• 在隐私模式下运行firefox(禁用所有缓存等)并不能解决问题

有任何想法吗？

问题如下:我们使用带有注释的hibernate作为O/R Mapper.

一些@Column注释看起来像:

@Column(columnDefinition = "longblob", name = "binaryData", nullable = true)

要么

@Column(columnDefinition = "mediumtext", name = "remark", nullable = true)

columnDefinition属性是特定于mysql的

例如,在postgres上,columnDefinition值应为"bytea"和"varchar(999999)"

而在oracle上可能还有别的东西.

当前在Schema Export时出现问题,例如在创建DDL语句时.

我能想到的可能的解决方法是 - 为DDL语句破解一些为文本替换的JDBC驱动程序(例如longblob-> bytea).这很难看,但会以某种方式工作 - 使用hibernate xml配置而不是注释.这可能会奏效,但我更喜欢注释

有人知道其他选择吗？Hibernate特定的解决方法是可以的,例如,如果columnDefinition属性可以包含方言特定值,例如

@Column(columnDefinition = "mysql->mediumtext, postgres->varchar(999999)", name = "remark", nullable = true)
