Question

我偶尔会在日志文件中收到以下错误字符串。我正在使用spring boot运行spring spring应用程序。我使用包含另一个配置文件的日志记录配置文件。 spring boot版本是v1.2.3（Spring cloud 1.0.1）。

％PARSER_ERROR [wex] 2015-06-01 12：30：22.180 DEBUG 6833 --- [http-nio-9000-exec-1] ...其余的日志消息

我看到了这个条目（Spring Boot - logback PARSER_ERROR），但是这似乎不适用。

logback.xml文件是：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <property name="LOG_FILE" value="logs/myservice.log"/>

    <!-- the rollover settings with mean a max size per log of 100Mb and 7 days -->
    <property name="MAX_HISTORY" value="7"/>
    <property name="MAX_FILE_SIZE" value="100MB"/>

Answer 1

在我的情况下，问题是由我从另一个项目中复制的以下格式引起的（它完美地工作）

%m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}

将格式更改为

%m%n${LOG_EXCEPTION_CONVERSION_WORD:-%rEx}

我们停止了这个错误。

奇怪的是，两个项目都在slf4j上使用logback-core-1.1.8和logback-classic-1.1.8。唯一的区别是wEx格式用于Spring Boot项目，并且在较旧的Spring 3项目中需要rEx格式。

请在您的Logback.xml中包含Spring提供的default.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml" />

Answer 3

在我们的案例中，问题出在我们使用的ELK系统中。我们运行了一个Elasticsearch-Logstash-Kibana日志收集系统，收集日志的日志存储代理正在将日期记录中的％PARSER_ERROR％[wex]插入到日志记录中。

在我们得到接受的解决方法之后，问题就消失了。

弹出启动日志记录中的％PARSER_ERROR [wex]
