org.glassfish.grizzly.http.ajp.AjpHandlerFilter.encodeHttpPacket(AjpHandlerFilter.java:282) 当使用 Apache 作为 GF 5 的负载平衡器时
org.glassfish.grizzly.http.ajp.AjpHandlerFilter.encodeHttpPacket(AjpHandlerFilter.java:282) when using Apache as load balancer for GF 5
我已经配置了一个带有 AJP 连接器的 Glassfish 5.0 实例，它可以用作负载平衡器，即使目前我只有一个 glassfish。
在 domain.xml 我有以下内容：
<http-service>
<access-log></access-log>
<virtual-server network-listeners="http-listener-1,http-listener-2,jk-connector" id="server"></virtual-server>
<virtual-server network-listeners="admin-listener" id="__asadmin"></virtual-server>
</http-service>
其中 jk-connector 是我使用的负载均衡器。
<network-config>
...
<protocols>
<protocol name="jk-connector">
<http default-virtual-server="server">
<file-cache></file-cache>
</http>
</protocol>
</protocols>
</network-config>
然后是监听器
<network-listeners>
<network-listener protocol="jk-connector" jk-enabled="true" port="8009" name="jk-connector" thread-pool="http-thread-pool" transport="tcp"></network-listener>
</network-listeners>
我的Apachehttp.conf如下：
LoadModule headers_module modules/mod_headers.so
LoadModule jk_module modules/mod_jk.so
# Where to find workers.properties
JkWorkersFile conf/workers.properties
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
<IfModule mod_rewrite.c>
Options +Indexes
Options +FollowSymlinks
RewriteEngine on
RewriteMap uc int:toupper
#rewrite per compatibilita' con vecchie URL dei servizi
RewriteRule ^/services/(.)(.*)$ /api/${uc:}Services?%{QUERY_STRING} [PT]
#RewriteRule ^/services/(.)(.*)$ http://%{HTTP_HOST}/api/${uc:}Services?%{QUERY_STRING} [R=301,L]
#solo nel caso di un GET
RewriteCond %{REQUEST_METHOD} GET
ReWriteRule ^(.*)/login.jsf;jsessionid=[A-Za-z0-9\.]+(.*)$ /login.jsf [L,R=301]
</IfModule>
例外情况是：

Using JDK 1.8.0_131, Glassfish 5.0, Apache 2.4.2
看来你正面临这个问题Glassfish bug (and this one)。
您可以在此处试用最新的 Glassfish 5 版本：http://download.oracle.com/glassfish/5.0.1/nightly
不幸的是，目前除了手动修复 grizzly JAR 文件外似乎没有其他解决方案。
您可以尝试以下方法：
- 下载 grizzly 2.4 源代码 (https://github.com/javaee/grizzly/archive/2.4.x.zip) 并提取它们
- 打开项目grizzly-http-ajp并构建它，如果由于缺少依赖导致构建失败，请在pom.xml
中将项目版本更改为2.4.3
- 如果编译没有问题，打开class AjpHandlerFilter
在第 276 行附近进行以下更改，使代码如下所示：
if (contentBuffer.hasRemaining()) {
return AjpMessageUtils.appendContentAndTrim(memoryManager,
encodedBuffer, contentBuffer);
} else if (encodedBuffer == null) {
encodedBuffer = Buffers.EMPTY_BUFFER;
}
保存并编译项目
- 转到
/grizzly-2.4.x/modules/http-ajp/target/classes/org/glassfish/grizzly/http/ajp/ 并复制为 AjpHandlerFilter 生成的 .class 文件
- 更新 Glassfish 安装的
glassfish-grizzly-extras-all.jar（在 glassfish/glassfish/modules 内）中的 AjpHandlerFilter.class。您可以使用 jar uf ${jar-file} ${class-file} 执行此操作。您需要确保路径正确并且您替换了 JAR 中的旧 .class 文件
或者您可以尝试找到项目 glassfish-grizzly-extras-all 的源代码，解决那里的问题并构建一个新的 glassfish-grizzly-extras-all.jar.
