Question

我正在使用logback，我想打印一个时期时间戳而不是日期和时间。

https://logback.qos.ch/manual/layouts.html#contextName引用了https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html，无法将日期格式化为时代。

我不敢相信此基本功能不可用，但我搜索了一段时间，却找不到它。

对于log4j log4j : current time in milliseconds，我发现的是相同的问题，但是@thegeko的建议import React, { Component } from 'react'; import { View, Text, TextInput, FooterTab,Button,TouchableOpacity, ScrollView, StyleSheet, ActivityIndicator ,Header,FlatList} from 'react-native'; import {Icon} from 'native-base'; import { createStackNavigator } from 'react-navigation'; import { SearchBar } from 'react-native-elements'; export default class RenderList extends Component { static navigationOptions = { title: 'Selected Item', header: null, }; constructor() { super(); this.state = { data: null, loading: true, search: '', }; } componentDidMount() { this.createViewGroup(); } createViewGroup = async () => { try { const response = await fetch( 'http://Dsenze/userapi/grouphier/viewgroup', { method: 'POST', headers: { Accept: 'application/json', 'Content-Type': 'application/json', }, body: JSON.stringify({ password: 'admin', username: 'admin', viewall: 'false', id: [4], startlimit: '0', valuelimit: '10', }), } ); const responseJson = await response.json(); const { groupData } = responseJson; this.setState({ data: groupData, loading: false, }); } catch (e) { console.error(e); } }; clickedItemText(clickedItem) { this.props.navigation.navigate('Item', { item: clickedItem }); } updateSearch = search => { this.setState({ search }); }; keyExtractor = ({ id }) => id.toString(); keyExtractor = ({ name }) => name.toString(); renderItem = ({ item }) => ( <TouchableOpacity style={styles.item} activeOpacity={0.4} onPress={() => { this.clickedItemText(item); }}> <Text>Hospital Id {item.id}</Text> <Text>Hospital Name {item.name}</Text> </TouchableOpacity> ); renderSeparator = () => { return ( <View style={{ height: 1, width: "86%", backgroundColor: "#CED0CE", }} /> ); }; render_FlatList_header = () => { var header_View = ( <View style={styles.header_footer_style}> <Text style={styles.textStyle}> FlatList Header </Text> </View> ); return header_View ; }; render() { const { loading, data } = this.state; return ( <ScrollView> <View style={styles.container1}> {this.state.loading ? ( <ActivityIndicator size="large" /> ) : ( <FlatList data={data} renderItem={this.renderItem} keyExtractor={this.keyExtractor} ItemSeparatorComponent={this.renderSeparator} ListHeaderComponent={this.render_FlatList_header} /> )} </View> </ScrollView> ); } }在logback中对我不起作用。

有人知道吗？

您可以使用此代码段打印Unix Epoch：

<layout class="net.logstash.logback.layout.LogstashLayout">
    <timeZone>UTC</timeZone>
    <timestampPattern>[UNIX_TIMESTAMP_AS_NUMBER]</timestampPattern>
</layout>

参考：https://github.com/logstash/logstash-logback-encoder#customizing-timestamp

如何在回传中将日期格式化为纪元时间戳？
