WildFly10日志为JSON

Question

我创建了一个类来记录JEE7 REST接收的请求(和响应)。

类使用SLF4J和logback构造JSON格式的日志事件，如

{
   "timestamp" : "2019-05-14 11:46:40.419",
   "level" : "INFO",
   "thread" : "default task-5",
   "mdc" : {
     "request.headers.Connection" : "keep-alive",
     "request.headers.Accept" : "*/*",
     "request.requestUri" : "http://localhost:8080/play/v1.0/map",
     "request.headers.User-Agent" : "PostmanRuntime/7.11.0",
     "request.headers.Cache-Control" : "no-cache",
     "request.method" : "GET",
     "request.headers.accept-encoding" : "gzip, deflate",
     "request.headers.Host" : "localhost:8080",
     "request.headers.Postman-Token" : "e03c8d8b-ebea-475c-bfaf-0ff8d4646081",
     "response.status" : "200",
     "message" : "200 GET /play/v1.0/map"
   },
   "logger" : "javax.ws.rs.container.ContainerRequestFilter",
   "message" : "you",
   "context" : "default"
 }

问题是WildFly将自己的信息添加到日志中，因此当前结果如下所示：

11:46:40,420 INFO  [stdout] (default task-5) {
11:46:40,420 INFO  [stdout] (default task-5)   "timestamp" : "2019-05-14 11:46:40.419",
11:46:40,420 INFO  [stdout] (default task-5)   "level" : "INFO",
11:46:40,420 INFO  [stdout] (default task-5)   "thread" : "default task-5",
11:46:40,420 INFO  [stdout] (default task-5)   "mdc" : {
11:46:40,420 INFO  [stdout] (default task-5)     "request.headers.Connection" : "keep-alive",
11:46:40,421 INFO  [stdout] (default task-5)     "request.headers.Accept" : "*/*",
11:46:40,421 INFO  [stdout] (default task-5)     "request.requestUri" : "http://localhost:8080/play/v1.0/map",
11:46:40,421 INFO  [stdout] (default task-5)     "request.headers.User-Agent" : "PostmanRuntime/7.11.0",
11:46:40,421 INFO  [stdout] (default task-5)     "request.headers.Cache-Control" : "no-cache",
11:46:40,421 INFO  [stdout] (default task-5)     "request.method" : "GET",
11:46:40,421 INFO  [stdout] (default task-5)     "request.headers.accept-encoding" : "gzip, deflate",
11:46:40,421 INFO  [stdout] (default task-5)     "request.headers.Host" : "localhost:8080",
11:46:40,421 INFO  [stdout] (default task-5)     "request.headers.Postman-Token" : "e03c8d8b-ebea-475c-bfaf-0ff8d4646081",
11:46:40,421 INFO  [stdout] (default task-5)     "response.status" : "200",
11:46:40,421 INFO  [stdout] (default task-5)     "message" : "200 GET /play/v1.0/map"
11:46:40,421 INFO  [stdout] (default task-5)   },
11:46:40,421 INFO  [stdout] (default task-5)   "logger" : "javax.ws.rs.container.ContainerRequestFilter",
11:46:40,421 INFO  [stdout] (default task-5)   "message" : "you",
11:46:40,421 INFO  [stdout] (default task-5)   "context" : "default"
11:46:40,422 INFO  [stdout] (default task-5) }

我希望我的日志文件只包含JSON对象，每行一个(为了清晰起见，上面的例子都打印得很清楚)

WildFly的日志配置文档不清楚如何实现这一点。

有人能帮我吗？

logback.xml

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

<configuration scan="true">
    <contextName>/psp/v1.0</contextName>

    <!-- ADD jboss-deployment-structure.xml -->
    <!-- WildFly adds slf4j as a default logging dependency. To avoid this exclude the main implementation in jboss-deployment-structure.xml descriptor -->

    <!-- don't log logback startup info -->
    <statusListener class="ch.qos.logback.core.status.NopStatusListener"/>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

如果您使用logback作为日志后端，那么您可以使用一个json附录来配置它。

您需要将这些依赖项添加到pom.xml中：

<dependencies>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.1.7</version>
    </dependency>

    <dependency>
        <groupId>ch.qos.logback.contrib</groupId>
        <artifactId>logback-json-classic</artifactId>
        <version>0.1.5</version>
    </dependency>

    <dependency>
        <groupId>ch.qos.logback.contrib</groupId>
        <artifactId>logback-jackson</artifactId>
        <version>0.1.5</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.9.3</version>
    </dependency>
</dependencies>

然后，您可以向logback (logback.xml)添加附录，如下所示：

<appender name="json" class="ch.qos.logback.core.ConsoleAppender">
    <layout class="ch.qos.logback.contrib.json.classic.JsonLayout">
        <jsonFormatter
            class="ch.qos.logback.contrib.jackson.JacksonJsonFormatter">
            <prettyPrint>true</prettyPrint>
        </jsonFormatter>
        <timestampFormat>yyyy-MM-dd' 'HH:mm:ss.SSS</timestampFormat>
    </layout>
</appender>

<logger name="jsonLogger" level="TRACE">
    <appender-ref ref="json" />
</logger>
