weblogic91使用扩展日志格式设置 HTTP 访问日志
登录console-Servers-AdminServer(admin)-Logging-选择http-Advanced-
其中Format 选择Extended
Extended Logging Format Fields : x-TrueIP date time cs-method cs-uri sc-status bytes cs(Referer) cs(User-Agent) cs(cookie)

其中x-TrueIP为自定义字段
class 如下：
import weblogic.servlet.logging.CustomELFLogger;
import weblogic.servlet.logging.FormatStringBuffer;
import weblogic.servlet.logging.HttpAccountingInfo;

public class TrueIP implements CustomELFLogger
{
//获取真实client ip
public void logField(HttpAccountingInfo metrics, FormatStringBuffer buff)
{
String ip = metrics.getHeader("X-Forwarded-For");
if(ip == null || ip.length() == 0) {
ip=metrics.getHeader("WL-Proxy-Client-IP");
}
if(ip == null || ip.length() == 0) {
ip=metrics.getRemoteAddr();
}
buff.appendValueOrDash(metrics.getHeader("ip"));
}
}

将TrueIP.class 增加到weblogic 的 setDomainEnv.sh 中
# SET THE CLASSPATH

CLASSPATH="${PRE_CLASSPATH}${CLASSPATHSEP}${WEBLOGIC_CLASSPATH}${CLASSPATHSEP}${POST_CLASSPATH}${CLASSPATHSEP}${WLP_POST_CLASSPATH}${CLASSPATHSEP}${WL_HOME}/integration/lib/util.jar::/home/weblogic/bea/user_projects/domains/base_domain/bin/TrueIP.class"
export CLASSPATH

重新启动weblogic nohup ./startWebLogic.sh >log&
报错信息如下：
