  • SpringBoot2.0 项目异常日志,但不影响运行(待解决)

    第一种:

    第三种:

    2019-04-18 02:44:42 [WARN] [org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver:197] - Resolved [org.springframework.web.HttpMediaTypeNotAcceptableException: Could not parse 'Accept' header [/]: Invalid mime type "/": does not contain subtype after '/']
    2019-04-18 02:47:57 [WARN] [org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver:197] - Resolved [org.springframework.web.HttpMediaTypeNotAcceptableException: Could not parse 'Accept' header [/]: Invalid mime type "/": does not contain subtype after '/']
    2019-04-18 05:26:21 [WARN] [org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver:197] - Resolved [org.springframework.web.HttpMediaTypeNotAcceptableException: Could not parse 'Accept' header [/]: Invalid mime type "/": does not contain subtype after '/']

    看下网上的解决方案:

    (1)原因是Tomcat的header缓冲区大小不够,只需要在 server.xml 中增加 maxHttpHeaderSize 字段即可:

    <Connector connectionTimeout="20000" maxHttpHeaderSize="10000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

    我是在 SpringBoot 中的配置文件添加了:(并没有解决任何问题)

    server.max-http-header-size=16KB

    (2)头部包含了特殊字符的原因:

    Tomcat 7.0.81以上支持,打开conf/catalina.properties在底部将

    #tomcat.util.http.parser.HttpParser.requestTargetAllow=|

    修改为

    tomcat.util.http.parser.HttpParser.requestTargetAllow=|,{,}

    目前服务经常不定时就挂了,没有错误日志。

    先弄了个监控重启的脚本,还没找出根本原因:

    #!/bin/bash
    while true
    do
        procnum=` ps -ef|grep "erp_server-1.0"|grep -v grep|wc -l`
        if [ $procnum -eq 0 ]; then
            nohup java -jar /srv/server/erp_server-1.0.jar &
        fi
        sleep 30
    done
